How to connect a TV to a computer in Windows 11

Is it possible to connect a TV or a second monitor to a computer in Linux

This guide will show you how to connect a TV or a second monitor to a computer in Windows 11. It will also talk about the available settings and solutions to common problems that arise when connecting a TV to a computer.

If you are a Linux user, then see the articles:

What you need to connect a TV or an additional monitor to a computer

To connect a TV or a second monitor to a computer or laptop, you need:

  • TV with HDMI connector (all modern models) or monitor with HDMI connector (all monitors released in the last two decades)
  • a computer with an HDMI connector – almost all computers and laptops will fit
  • HDMI cable

Choosing an HDMI cable

I approached the choice of HDMI cable quite simply – I chose the cheapest with the right length, which I found in the store. In subsequent use, this cable fully satisfied my needs.

Despite its cheapness, this HDMI cable supports:

  • UHD 4K@2160P / 4K@60Hz / 4K HDR
  • High Speed HDMI 2.0
  • Gold plated contacts

Cable length 1.8 meters.

Apparently, these are already the minimum characteristics – perhaps more expensive models support higher resolutions and data transfer at higher speeds.

What TV can be connected to a computer

Using an HDMI cable, you can connect any TV with an HDMI connector. This connector is present on all TVs and monitors released in the last decade.

Older TVs without an HDMI connector can also be connected to a computer, but instead of an HDMI cable, you will need a wire with an adapter.

As for the technical characteristics of the TV (diagonal size, screen resolution, screen refresh rate, aspect ratio), this is not critical. That is, you do not have to select a TV model with the same characteristics as your monitor. Modern video cards support a variety of modes (screen resolutions and refresh rates), including the video card will work with a TV if the screen resolution is different from the monitor.

For example, the characteristics of my devices:

  • laptop monitor: 17", 1920×1080, 16:9, 120 Hz
  • TV (all specifications): 32", 1366x768p, 16:10, 60Hz

That is, these are two very different devices, but at the same time I had no problems when they worked together.

How to connect HDMI cable to TV

Plug the HDMI cable into the connectors of the computer (laptop) and TV.

Both on the computer and on the TV, there may be several HDMI connectors – remember the number of the selected connector.

Turn on your computer and TV.

Note: The HDMI cable can be connected when the computer and TV are already on.

Use the remote control to select “HDMI” as the input source on the TV.

If, after selecting HDMI as the signal source on the TV, you see the message “No Input Signal”, then:

  1. Select HDMI with a different number.
  2. Move the wire, it may not be firmly connected to the computer or TV socket.
  3. Make sure your computer is on.
  4. The monitor on the computer should not be turned off due to inactivity.

How to use a TV connected to a computer

There are two main modes:

  • join displays
  • mirror (duplication) of images on both displays

When displays are combined, the total space expands. That is, if you connected another 1920×1080 display to a computer with one 1920×1080 display, then now the resolution of your virtual screen becomes 3840×1080, if there are three such displays, the resolution will become 5760×1080. You can drag program windows from one display to another. Some apps and games support these wide virtual screens.

When the image is repeated (Mirror), the same image will be shown on both displays.

Among the displays, Primary stands out. This is the one connected first. A feature of the main display is that it shows desktop shortcuts, although this can be changed in the settings.

In the next video, the TV is connected to the computer. To play a YouTube video on a TV, the web browser window is dragged from the monitor to the TV.

Where are the settings for the second display and TV

Open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Here you will see the display settings.

Select the display (or TV) you want to customize.

At the top of the settings window, you'll see a display layout.

The “Multiple displays” settings area appears only if multiple monitors (TVs) are connected to the computer, it contains settings for the computer's behavior when working with multiple displays. To see these settings, click on the arrow icon on the right side.

The following are settings common to all displays.

Then at the bottom of the window are settings specific to each display.

Select a monitor to change its settings.

The following settings are individual for each monitor:

  • Scale
  • Display resolution
  • Display orientation

When you go to the “Advanced display” settings section, you will also be able to adjust the refresh rate for each of the displays.

How to set Main (Primary) Monitor

By default, desktop shortcuts are shown on the Main Display. You can change, i.e. choose a new primary monitor. For this:

1. Open the “Settings” application, this can be done by pressing Win+i.

2. Go to the “Display” section.

3. Select the display you want to make Primary.

4. Expand the “Multiple displays” settings area.

5. Check the “Make this my main display” checkbox.

How to turn off the display or TV in the settings, without physically disconnecting

You can disconnect the HDMI cable from your TV or computer at any time, but this is not always convenient. In addition, you may want to turn off the computer monitor or the laptop's built-in monitor.

To turn off any monitor or TV in Settings, open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Below the monitor layout, you will see a drop-down list of the following items:

  • Duplicate these displays
  • Extend these displays
  • Show only on 1
  • Show only on 2

Selecting the “Show only on…” option will cause the image to be displayed on only one display (or TV), and all others will be disabled.

A disabled monitor will stop working (it will no longer receive an input signal), but the disabled monitor will still be available in the settings. You can turn it back on at any time. To enable all monitors, select one of the following options from the drop-down list above:

  • Duplicate these displays
  • Extend these displays

How to make the TV show the same thing as the monitor

Open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Under the monitor layout, select “Duplicate these displays” from the drop-down list.

As a result, the resulting settings for both monitors at once will be shown.

Now the image on the monitor and TV is the same:

You may notice that the picture on the TV is slightly cropped.

This may be due to the aspect ratio or screen resolution.

In my case, both the aspect ratio and the screen resolution of the monitor built into the laptop and the TV are different. Changing the screen resolution to what the TV has somewhat reduced the problem with cut edges.

How to make the TV become an extension of the monitor

Open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Under the monitor layout, select “Extend these displays” from the drop-down list.

In this case, one of the monitors will be considered the main one. In this case, each of the monitors will show its own desktop, which, in fact, is one.

Why can't I drag the program window to the second screen

If you see two displays in the settings, but you can’t drag the program window to the TV or the second display, then try dragging the window to the other side. That is, if you, for example, are trying to drag a program window to the left side, then try dragging it to the right side instead.

The fact is that the physical location of the second monitor (TV) and its location in the settings can be different. To fix this, swap the monitors in the settings.

In addition to the location of the monitors to the left and right of each other, other options are possible.

You can place one of the monitors (or TVs) above the other.

In this case, the screen resolution and desktop area will change accordingly.

If you have many monitors, you can place them however you want, not all monitors need to be in a straight line horizontally. You can arrange them, for example, as 3×2, that is, two rows of three monitors.

How to make the Taskbar only show on the Main monitor

If you want the taskbar to be shown only on the Main monitor, then follow the steps below.

Open the “Settings” app by pressing Win+i.

Go to “Personalization” → “Taskbar”.

Expand the “Taskbar behavior” section.

Uncheck the “Show my taskbar on all displays” setting.

How to make the taskbar show on all monitors

If you want the taskbar to be shown on all connected monitors and TVs, then follow these steps.

Open the “Settings” app by pressing Win+i.

Go to “Personalization” → “Taskbar”.

Expand the “Taskbar behavior” section.

Check the box next to “Show my taskbar on all displays”.

After that, the Taskbar will be shown on all monitors.

How to set different desktop wallpapers for monitor and TV

You can set a different desktop wallpaper for all connected monitors and TVs.

To do this, open the “Settings” application, this can be done by pressing Win+i.

Go to “Personalization” → “Background”.

Right click on the photo you want to set as your desktop wallpaper. From the pop-up menu, select the number of the monitor for which you want to set this desktop background.

Now the desktop wallpaper on the monitor and TV is different.

How to identify displays

If you have multiple monitors and you are confused about their settings, then you can enable the display of the number on the screen of each monitor.

Open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Click the “Identify” button, which is located under the schematic image of the monitors.

After that, each monitor and TV will show squares with display numbers in the settings.

Why is the sound played through a computer (laptop) and not through a TV

An HDMI cable can carry both video and audio. But even after connecting the TV with an HDMI cable, sound is still output from the laptop speakers or computer speakers.

To change the audio output source, go to the audio settings. To do this, open the “Settings” application, this can be done by pressing Win+i.

Go to the “Sound” section.

In the “Output” section, select “Audio for Displays”.

You can also expand the settings for each sound source by clicking the arrow symbol to the right of the source name. In the window that opens, you can fine-tune each sound source.

Why did the sound disappear after turning off the TV on the laptop (computer)

To change the audio output source, go to the audio settings. To do this, open the “Settings” application, this can be done by pressing Win+i.

Go to the “Sound” section.

In the “Output” section, select “Speakers”.

Setting the action when closing the laptop lid when using a second monitor

If you are using a laptop, closing the laptop lid when additional monitors are connected to it may not be what you expect. For example, when you close the laptop lid, the computer goes into Sleep mode or shuts down, but you expect to be able to work on a second monitor or watch TV connected to the computer.

To control how the computer behaves when the laptop lid is closed, open the “Control Panel”.

In the Control Panel, go to “Category” → “Small icons”.

Open the “Power Options” section.

Click on the “Choose what closing the lid does” link.

You can also go to this setting by running the command:

control /name Microsoft.PowerOptions /page pageGlobalSettings

In the window that opens, note that all actions are configured for two modes:

  • On battery
  • Plugged in

For the action for “When I close the lid”, select “Do nothing”.

How to prevent the monitor from turning off

If there is no activity for some time (for example, 10 minutes), the monitors will be turned off. You can disable the setting to turn off displays.

To control when monitors turn off due to inactivity, open the “Control Panel”.

In the “Control Panel”, go to “Category” → “Small icons”.

Open the “Power Options” section.

Click on the “Choose when to turn off the display” (or “Change when the computer sleeps” link).

You can also go to this setting by running the command:

control /name Microsoft.PowerOptions /page pagePlanSettings

In the window that opens, note that all actions are configured for two modes:

  • On battery
  • Plugged in

Set longer time intervals before turning off the monitor and entering sleep mode, or select “Never”.

1. Open the Settings Manager app, go to the “Display” section.

2. Select the monitor you want to make your primary

3. Activate the “Primary Display” slider next to the monitor name.

How to turn off the display or TV in the settings, without physically disconnecting

You can disconnect the HDMI cable from your TV or computer at any time, but this is not always convenient. In addition, you may want to turn off the computer monitor or the laptop's built-in monitor.

To turn off any monitor or TV in settings, open “Display” settings.

Select the monitor you want to turn off – this can be done by clicking on the schematic image of the monitor with a number or by selecting the name of the monitor from the drop-down list.

Then turn off the monitor using the slider marked 2 in the screenshot.

A disabled monitor will stop working (it will no longer receive an input signal), but the disabled monitor will still be available in the settings. You can turn it back on at any time.

How to make the TV show the same thing as the monitor

Go to Setting Manager → Display.

Select the “Mirror displays” option.

You may notice that the display sizes are not the same – this is due to the fact that they have different screen resolutions.

To ensure that the image is exactly the same on both displays, select the same screen resolution.

Please note that when “Mirror displays” is selected, the "Primary Display" option becomes unavailable because both monitors become equal.

As a result, the resulting settings for both monitors at once will be shown.

Now the image on the monitor and TV is the same:

How to make the TV become an extension of the monitor

Go to Setting Manager → Display.

Disable the “Mirror displays” option.

In this case, one of the monitors will be considered the main one. In this case, each of the monitors will show its own desktop, which, in fact, is one.

Why can't I drag the program window to the second screen

If you see two displays in the settings, but you can’t drag the program window to the TV or the second display, then try dragging the window to the other side. That is, if you, for example, are trying to drag a program window to the left side, then try dragging it to the right side instead.

In addition to the location of the monitors to the left and right of each other, other options are possible.

You can place one of the monitors (or TVs) above the other.

In this case, the screen resolution and desktop area will change accordingly.

If you have many monitors, you can place them however you want, not all monitors need to be in a straight line horizontally. You can arrange them, for example, as 3×2, that is, two rows of 3 monitors.

After changing the relative position of monitors in the settings, shortcuts and the taskbar moved to another monitor

If you swapped them in the monitor settings, then the desktop shortcuts and the taskbar are most likely moved to the leftmost monitor (TV). This is due to the fact that by default it is set in the settings that the Desktop shortcuts and the Panel are placed automatically, without being tied to the Primary display. How to make the Desktop shortcuts and Panel show on the Primary monitor is shown below.

Customizing the Xfce Panel, Desktop shortcuts and Notifications on a computer with multiple monitors

Options related to advanced settings for your TV or second monitor are located in the following settings sections:

  • Panel
  • Desktop
  • Notifications

All of these settings can be quickly accessed at once by going to Setting Manager → Display and then clicking the letter “i” next to the “Primary Display” enable slider.

You will see the following window:

The primary display is currently configured to show

  • Xfce Panel
  • Desktop icons
  • Notifications

In this window, you can click the “Configure” buttons next to the setting you want to change.

How to make the taskbar show on the main monitor

Go to Setting Manager → Display, click the “i” next to the “Primary Display” slider.

Opposite “Xfce Panel” click the “Configure” button.

On the “Display” tab, find the “Output” setting.

Several options will be offered:

  • Automatic (that is, on the very first (left) monitor in the settings)
  • Primary (on the main monitor)
  • HDMI-1 (monitor connected via HDMI cable)
  • ePD-1 (laptop built-in monitor)

To show the taskbar on the main monitor, select the “Primary” option.

How to make the taskbar show on all monitors

If you want the taskbar to be shown on all connected monitors and TVs, then follow these steps.

Go to Setting Manager → Display, click the “i” next to the “Primary Display” slider.

Opposite “Xfce Panel” click the “Configure” button.

On the “Display” tab, find and activate the “Span monitors” setting.

After that, the Taskbar will be shown on all monitors. Open programs will be added to the taskbar from left to right. That is, at first the taskbar will be filled on the very first (left) monitor and then it will start to fill on the subsequent ones.

How to set different desktop wallpapers for monitor and TV

You can set a different desktop wallpaper for all connected monitors and TVs.

To do this, go to Setting Manager → Display, click the letter “i” next to the “Primary Display” enable slider.

Opposite “Desktop icons” click the “Configure” button.

You will see something like this:

Move this dialog to the display you want to edit the settings for

That is, in order to change the desktop wallpaper, you need to move the window that opens to the monitor (or TV) for which you want to set a new wallpaper.

For example, the inscription “Wallpaper for Monitor 0 (eDP-1)” means that the wallpaper will be set for the monitor built into the laptop.

And the inscription “Wallpaper for Monitor 1 (HDMI-1)” means that the wallpaper for the device connected via HDMI cable is currently being configured.

How to make Desktop icons show on Primary monitor

By default, desktop icons will be shown on the first (leftmost) monitor or TV. To change this, go to Setting Manager → Display, click on the letter “i” next to the “Primary Display” enable slider.

Opposite “Desktop icons” click the “Configure” button.

In the “Desktop” window that opens, go to the “Icons” tab.

Find and activate the “Show icons on primary display” setting.

How to make notifications appear on the Primary display

By default, notifications are shown on the display where the mouse cursor is when the notification is displayed. To change this, go to Setting Manager → Display, click on the letter “i” next to the “Primary Display” enable slider.

Opposite “Notifications”, click the “Configure” button.

In the window that opens, on the “General” tab, find the “Show notification on” setting and select “primary display” in the drop-down list.

How to make notifications appear on the display with the mouse pointer

Go to Setting Manager → Display, click the “i” next to the “Primary Display” slider.

Opposite “Notifications”, click the “Configure” button.

In the window that opens, on the “General” tab, find the “Show notification on” setting and select “display with mouse pointer” in the drop-down list.

Why are monitors of different sizes in the settings

If monitors have different screen resolutions, they will be shown in different sizes in the settings.

If you wish, you can choose the same screen resolutions for all monitors and TVs.

The same screen resolutions can be set both in the “Mirror displays” mode, and when using monitors to show different areas of the desktop.

Is it necessary to set the same resolution for the monitor and TV

No, it doesn’t need.

Moreover, the TV or monitor may not support the resolution or screen refresh rate that the second monitor supports.

For example, if you have selected a screen resolution of 1920×1080 in the TV settings, but the TV itself only supports 1366×768, then the picture will be displayed with a resolution of 1366×768 anyway.

How to make the monitor display popup windows to identify displays

If you have multiple monitors and you are confused about their settings, then you can enable the display of the name and number on the screen of each monitor.

Go to Setting Manager → Display, open the “Advanced” tab.

Activate the setting “Identifying Displays. Show popup windows to identify displays”.

How to remove pop-up windows with monitor names and numbers

Go to Setting Manager → Display, open the “Advanced” tab.

Disable the “Show popup windows to identify displays” setting.

How to enable automatic configuration of connected displays

Go to Setting Manager → Display, open the “Advanced” tab.

Activate the “Configure new displays when connected” setting.

How to turn off automatic configuration of connected displays

Go to Setting Manager → Display, open the “Advanced” tab.

Disable the “Configure new displays when connected” setting.

Why is the sound played through a computer (laptop) and not through a TV

An HDMI cable can carry both video and audio. But even after connecting the TV with an HDMI cable, sound is still output from the laptop speakers or computer speakers.

To change the sound output source, go to the sound settings (Volume Control). This can be done via Setting Manager → PulseAudio Volume Control.

Or find this settings window through the start menu.

Another quick way to get to the sound settings is to click on the speaker icon next to the clock and select “Audio mixer”.

The “Output Devices” tab will open, you can search there for a TV or HDMI device as an audio output source, but in my case there was no such device. Only “Speakers” were available as “Port”.

To switch the sound output to an HDMI device, go to the “Configuration” tab and in the drop-down list of the “Profile” setting, select the item with HDMI.

For example, to get the sound through the TV, I chose “Digital Stereo (HDMI) Output” instead of “Analog Stereo Output”.

Why did the sound disappear after turning off the TV on the laptop (computer)

To change the sound output source, go to the sound settings (Volume Control). This can be done through Setting Manager → PulseAudio Volume Control, or find this settings window through the start menu. Another quick way to get to the sound settings is to click on the speaker icon next to the clock and select “Audio mixer”.

Go to the “Configuration” tab and in the drop-down list of the “Profile” setting, select “Analog Stereo Output”.

Setting the action when closing the laptop lid when using a second monitor

If you are using a laptop, closing the laptop lid when additional monitors are connected to it may not be what you expect. For example, when you close the laptop lid, the computer goes into Suspend (Sleep) mode or shuts down, and you expect to be able to work on a second monitor or watch TV connected to the computer.

To control how the computer behaves when the laptop lid is closed, go to Settings Manager → Power Management.

You can also find this settings window through the Start menu.

Here in the “System” tab you can change the behavior performed when the laptop lid is closed.

Please note that the behavior of the computer in two modes is separately configured:

  • On battery – when the laptop is running on battery power
  • Plugged in – when the laptop is running on mains power

The “When laptop lid is closed” setting determines the action that the computer will perform when the laptop lid is closed, even if a second monitor or TV is connected to it.

The following options are available:

  • Switch off display – disable built-in laptop display
  • Suspend – Stops all applications and puts the computer into low power mode. When you turn on the computer, it returns to the same state that it was before Suspend. The difference from Hibernate is that the computer turns on faster, although it continues to consume energy.
  • Hibernate – hibernation mode, writing the current state of the computer and RAM to the hard disk and turning off the computer. When you turn on the computer, it returns to the same state that it was before Hibernate. The difference from Suspend is that the computer completely stops consuming power and cannot lose data due to the fact that the battery is dead. But it turns on a little longer than when exiting the Suspend state.
  • Lock screen – Show a screensaver that requires the user to enter a password.

If you do not want the laptop to turn off when the lid is closed, then select “Switch off display” or “Lock screen”.

How to connect a TV to a computer in Linux in Cinnamon (Linux Mint, LMDE)

Is it possible to connect a TV or a second monitor to a computer in Linux

This post will show you how to connect a TV or a second monitor to a Linux computer with the Cinnamon desktop environment. It will also talk about the available settings and solutions to typical problems that arise when connecting a TV to a computer.

Cinnamon is used in distributions such as Linux Mint and LMDE, and the Cinnamon desktop environment can be installed on any other distribution. In my case, I'm using Arch Linux with Cinnamon.

If you have a different desktop environment, then see the articles:

If you are a Windows user, then see the article “How to connect a TV to a computer in Windows 11”.

What you need to connect a TV or an additional monitor to a computer

To connect a TV or a second monitor to a computer or laptop, you need:

  • TV with HDMI connector (all modern models) or monitor with HDMI connector (all monitors released in the last two decades)
  • a computer with an HDMI connector – almost all computers and laptops will fit
  • HDMI cable

Choosing an HDMI cable

I approached the choice of HDMI cable quite simply – I chose the cheapest with the right length, which I found in the store. In subsequent use, this cable fully satisfied my needs.

Despite its cheapness, this HDMI cable supports:

  • UHD 4K@2160P / 4K@60Hz / 4K HDR
  • High Speed HDMI 2.0
  • Gold plated contacts

Cable length 1.8 meters.

Apparently, these are already the minimum characteristics – perhaps more expensive models support higher resolutions and data transfer at higher speeds.

What TV can be connected to a computer

Using an HDMI cable, you can connect any TV with an HDMI connector. This connector is present on all TVs and monitors released in the last decade.

Older TVs without an HDMI connector can also be connected to a computer, but instead of an HDMI cable, you will need a wire with an adapter.

As for the technical characteristics of the TV (diagonal size, screen resolution, screen refresh rate, aspect ratio), this is not critical. That is, you do not have to select a TV model with the same characteristics as your monitor. Modern video cards support a variety of modes (screen resolutions and refresh rates), including the video card will work with a TV if the screen resolution is different from the monitor.

For example, the characteristics of my devices:

  • laptop monitor: 17", 1920×1080, 16:9, 120 Hz
  • TV (all specifications): 32", 1366x768p, 16:10, 60Hz

That is, these are two very different devices, but at the same time I had no problems when they worked together.

How to connect HDMI cable to TV

Plug the HDMI cable into the connectors of the computer (laptop) and TV.

Both on the computer and on the TV, there may be several HDMI connectors – remember the number of the selected connector.

Turn on your computer and TV.

Note: The HDMI cable can be connected when the computer and TV are already on.

Use the remote control to select “HDMI” as the input source on the TV.

If, after selecting HDMI as the signal source on the TV, you see the message “No Input Signal”, then:

  1. Select HDMI with a different number.
  2. Move the wire, it may not be firmly connected to the computer or TV socket.
  3. Make sure your computer is on.
  4. The monitor on the computer should not be turned off due to inactivity.

How to use a TV connected to a computer

There are two main modes:

  • join displays
  • mirror (duplication) of images on both displays

When displays are combined, the total space expands. That is, if you connected another 1920×1080 display to a computer with one 1920×1080 display, then now the resolution of your virtual screen becomes 3840×1080, if there are three such displays, the resolution will become 5760×1080. You can drag program windows from one display to another. Some apps and games support these wide virtual screens.

When the image is repeated (Mirror), the same image will be shown on both displays.

Among the displays, Primary stands out. This is the one connected first. A feature of the main display is that it shows desktop shortcuts, although this can be changed in the settings.

In the next video, the TV is connected to the computer. To play a YouTube video on a TV, the web browser window is dragged from the monitor to the TV. It also selects HDMI as the audio output source to play the sound on a TV instead of playing it on a computer (laptop).

Where are the settings for the second display and TV

Open the Settings application (System Setting), go to the “Display” section.

Here you will see the display settings.

Select the display (or TV) you want to customize.

Each display will have its own set of settings.

How to make the TV show the same thing as the monitor

Go to System Setting → Display.

Select the “Mirror” option.

As a result, the resulting settings for both monitors at once will be shown.

How to make the TV become an extension of the monitor

Go to System Setting → Display.

Select the “Join Displays” option.

In this case, one of the monitors will be considered the main (Primary) one. In this case, each of the monitors will show its own desktop, which, in fact, is one.

Why can't I drag the program window to the second screen

If you see two displays in the settings, but you can’t drag the program window to the TV or the second display, then try dragging the window to the other side. That is, if you, for example, are trying to drag a program window to the left side, then try dragging it to the right side instead.

The fact is that the physical location of the second monitor (TV) and its location in the settings can be different. To fix this, swap the monitors in the settings:

In addition to the location of the monitors to the left and right of each other, other options are possible.

You can place one of the monitors (or TVs) above the other.

In this case, the screen resolution and desktop area will change accordingly.

If you have many monitors, you can place them however you want, not all monitors need to be in a straight line horizontally. You can arrange them, for example, as 3×2, that is, two rows of 3 monitors.

Why are monitors of different sizes in the settings

If monitors have different screen resolutions, then they will be shown in different sizes in the settings.

Is it necessary to set the same resolution for the monitor and TV

No, it doesn’t need.

Moreover, the TV or monitor may not support the resolution or screen refresh rate that the second monitor supports.

For example, if you have selected a screen resolution of 1920×1080 in the TV settings, but the TV itself only supports 1366×768, then the picture will be displayed with a resolution of 1366×768 anyway.

How to install the Primary monitor

By default, desktop shortcuts are shown on the Primary monitor. You can change, i.e. choose a new primary monitor. For this:

1. Open the System Setting app, go to the “Display” section.

2. Select the monitor you want to make your primary

3. Click the “Set as Primary” button next to the monitor name.

How to turn off the display or TV in the settings, without physically disconnecting

You can disconnect the HDMI cable from your TV or computer at any time, but this is not always convenient. In addition, you may want to turn off the computer monitor or the laptop's built-in monitor.

To turn off any monitor or TV in settings, open “Display” settings.

Select the monitor you want to turn off – this can be done by clicking on the schematic image of the monitor with a number or by selecting the name of the monitor from the drop-down list.

Then turn off the monitor using the slider marked 2 in the screenshot.

A disabled monitor will stop working (it will no longer receive a signal), but the disabled monitor will still be available in the settings. You can turn it back on at any time.

Why does the sound come through a computer (laptop), and not through a TV

Go to sound settings (Sound). This can be done via System Setting → Sound. Or by clicking the musical note icon next to the clock and selecting “Sound System”.

Go to the “Output” tab.

Select “HDMI / DisplayPort Built-in Audio” as the output device.

Why did the sound disappear after turning off the TV

Go to sound settings (Sound). This can be done via System Setting → Sound. Or by clicking the musical note icon next to the clock and selecting “Sound System”.

Go to the “Output” tab.

Select “Speakers Built-in Audio” as the output device.

How to make the TV (on the second monitor) also show desktop icons

Go to System Setting → Desktop.

In the “Desktop Layout” drop-down menu, select the option you need:

  • No desktop icons
  • Show desktop icons on primary monitor only
  • Show desktop icons on non-primary monitor(s) only
  • Show desktop icons on all monitors

Setting the action when closing the laptop lid when using a second monitor

Go to System Setting → Power Management.

Here you can change the behavior performed when the laptop lid is closed.

In order for the action selected when closing the laptop lid to be applied even if a second monitor is connected, activate the “Perform lid-closed action even with external monitors attached” setting.

When connecting and disconnecting the TV, the next time you close the lid of the laptop, the monitor goes into sleep mode

On my laptop, the lid close action is set to Do nothing. This setting works fine, that is, when I close the lid of the laptop, the computer continues to work.

But when connecting and disconnecting the TV, the following problem was noticed: when the lid is closed, the laptop goes into sleep mode (Suspend), although the settings are set to “Do nothing”.

This looks like a bug. To fix it, install the “gnome-tweaks” package.

Run:

gnome-tweaks

On the “General” tab, find and disable the “Suspend when laptop lid is closed” setting.

Disabling this setting resolved the issue.

How to watch IPTV on your phone

How to connect to digital TV from a computer in Linux (IPTV, DVB-IP and TVoIP)

IPTV, DVB-IP and TVoIP

From a technical point of view, Internet TV provided by Internet Service Providers (ISPs) is different from video streaming such as YouTube or even live TV broadcasts.

Internet providers for digital television services use local IP addresses and multicast. Such broadcasting is tightly tied to the local resources of ISPs (that is, it will not be possible to watch TV channels of an ISP “A” while connected to the Internet via ISP “B”). Due to the use of multicast, the load on the broadcasting server does not increase with each additional client connection. Another feature is that the UDP protocol is used, an example is the stream address:

udp://@225.77.225.5:5000

Often, Internet service providers offer a set-top box that allows you to convert the data stream from the network into a TV signal. Also, the set-top box can be used to decrypt the data stream if the broadcast is encrypted.

Streaming broadcasting of television channels on the Internet is closer to YouTube than we are used to. An example of the Euronews stream address is http://evronovosti.mediacdn.ru/sr1/evronovosti/playlist.m3u8. That is, HTTP and TCP protocols are used.

For the end user, it may not matter what happens “under the hood”. Just remember that some streaming addresses are ISP bound and only work when you're connected to a specific network.

List of Best IPTV Applications for Linux

The list of the best IPTV apps for Linux that you can find is as follows:

Astroncia IPTV

Homepage: https://gitlab.com/astroncia/iptv

IPTV player with EPG support.

Functions:

  • Watching IPTV (from m3u / m3u8 / xspf playlist, local or remote)
  • XTream API support
  • Viewing unencrypted streams UDP (multicast), HTTP, HLS (m3u8)
  • Adding channels to favorites
  • Recording TV programs
  • Hotkeys
  • Channel search
  • TV program (EPG) support in XMLTV and JTV formats
  • Display of technical information - video / audio codec, bit rate, resolution
  • Channel groups (from playlist and custom)
  • Hide channels
  • Sorting channels
  • Video settings for each channel - contrast, brightness, hue, saturation, gamma
  • Change user agent for each channel
  • M3U playlist editor
  • TV archive
  • Internalization
  • MPRIS support (and remote control using KDE Connect)
  • Taking screenshots

Excellent program, functional and intuitive. One of my favorites for watching IPTV.

FreeTUXTV

Homepage: https://github.com/freetuxtv/freetuxtv

One of the best for IPTV under Linux. Available in 21 languages and with the ability to record content for later viewing. To start using it, you just need to download and install the program, find the URL of the m3u playlist you want to view, open the app, paste the link and hit search…

Small tests have shown that links to built-in TV channels are often not working.

It was possible to add channels from the .m3u file. But for this, I had to start a local web server and copy the file to it in order to specify a link in FreeTUXTV, since the program, apparently, cannot open local files with channel lists.

In general, the program is quite buggy and was unable to open .m3u8 files. But at least it successfully copes with the display of digital television.

Hypnotic

Homepage: https://github.com/linuxmint/hypnotix

This is an IPTV streaming app supporting live TV, movies and series. It can support multiple IPTV providers of the following types:

  • M3U URL;
  • Xtream API;
  • M3U local playlist.

Hypnotic was created by the developers of Linux Mint, so this distribution comes pre-installed with it.

In my tests, the program was unable to open local .m3u files. At the same time, the program itself already has built-in lists of TV channels, broken down by country.

Megacube

Home page: https://megacubo.tv/online/en/

It is an intuitive, free and open source IPTV player.

Stremio

Homepage: https://www.stremio.com/

One-stop hub for aggregating video content (movies, TV shows, series, live TV or web feeds).

The program asks to register. Unable to play digital TV without registration. This is where my acquaintance with the program ended.

Kodi

Homepage: https://kodi.tv/

Certainly one of the best. A complete multimedia center with which you can watch IPTV and much more, as it has a large number of functions and add-ons to expand its capabilities.

Miro

Homepage: http://www.getmiro.com/

Another IPTV player available for Linux. It has many interesting features, but perhaps the most notable is that it allows you to handle many video formats and HD content without any problems. You just need to download it, install it, open the app, find the m3u link you want to see and put it in the app to start watching channels.

VLC

Homepage: https://www.videolan.org/vlc/index.html

As you know, this media player is one of the most powerful and complete and it is available for Linux. And among its features, there is also support for ITPV. Download, install, open the app, go to Media, Open Network Location, paste the URL and click Play.

tvheadend

Homepage: https://tvheadend.org/

Another option for streaming video. It also supports recording, and you can manage it via the web interface after installing it if you navigate from your web browser to http://[your-ip]:9981/, replacing [your-ip] with your address. For example, http.//192.168.1.2:9981.

IPTVnator

Homepage: https://www.electronjs.org/apps/iptvnator

Although many are not fans of Electron for obvious reasons, here is another application based on it and compatible with IPTV lists (m3u, m3u8). It has a very simple interface that you can easily learn to manage from the first moment.
