How to enable automatic brightness adjustment on a Samsung monitor depending on the lighting around (using the ViewFinity S6 LS34A650UBEXXT model as an example)

Automatically adjust the brightness of your Samsung monitor based on ambient light

The brightness of the monitor (or TV) is perhaps one of the key settings. Setting the brightness to a low level will not reveal the capabilities of even a good (and expensive) monitor. At a low brightness level, the picture will be more faded and much less impressive.

For watching movies, you can simply select the maximum brightness level – and you can not go wrong.

But for many hours of work, excessive brightness can make eyes tired sometimes.

You also need to take into account that when working in a dark room, it is usually more comfortable with a slightly lower brightness. And on a clear day, when there is a lot of sunlight in the room, on the contrary, we want the monitor to be brighter.

Manufacturers have taken care of us: Samsung monitors have a sensor that captures the current brightness in the vicinity of the monitor. Using this sensor, the monitor can automatically adjust the brightness according to the environment. It's comfortable!

How to set automatic brightness on a Samsung monitor (using the ViewFinity S6 LS34A650UBEXXT as an example)

There are several auto brightness settings on Samsung monitors:

  • Adaptive Picture
  • Dynamic Brightness
  • Eco Sensor Mode
  • Eco Saving Plus
  • Picture Mode (Dynamic Contrast)

Agree that it is a bit surprising that more than one setting is responsible for setting the automatic brightness. Some of these settings perform the same function, and when one setting is activated, the corresponding option with a different name becomes unavailable.

In any case, to get the best result, before changing anything in the monitor settings, you need to thoroughly understand them.

Each of these auto-brightness settings is discussed in more detail below, and recommendations are given at the end of the article which of them to use for best results.

Adaptive Picture

The first setting for automatic brightness change is in the “Eye Care” group of settings.

The setting is called “Adaptive Picture”. It optimizes brightness and maximizes image quality in real time based on lighting conditions and content being viewed.

After it is enabled, the “Min. Backlight” setting will become active: reducing the screen backlight to a minimum when the adaptive image is turned on.

That is, in the “Min. Backlight” setting, you can set a level below which the brightness will not decrease.

Please note that when you turn on the “Adaptive Picture” option, it may appear that the screen brightness has not changed. The fact is that the decrease in brightness occurs gradually, even if it is dark around the monitor. When you disable the “Adaptive Picture” option, the brightness immediately returns to the original.

The “Adaptive Picture” option is available only if “Eco Sensor Mode” is off.

Dynamic Brightness

In the “System” group of settings, you will find the “Dynamic Brightness” option.

Dynamic Brightness” automatically adjusts brightness to provide the best screen contrast based on current lighting conditions.

That is, the difference between “Dynamic Brightness” and “Adaptive Picture” is that “Adaptive Picture” automatically changes the “Brightness” setting (brightness of the screen as a whole). And “Dynamic Brightness” automatically changes the “Contrast” setting (the contrast between bright and dark areas).

Dynamic Brightness” is not available if:

  • Eye Care Mode is on.
  • Eco Saving Plus is enabled.
  • PIP/PBP mode enabled.
  • Picture Mode is set to Dynamic Contrast.

Eco Sensor Mode

In the “System” group of settings, you will find another option for automatically adjusting the brightness, this is “Eco Sensor Mode”.

The Eco Sensor Mode option optimizes brightness in real time, based on your lighting environment.

You may be wondering how the “Eco Sensor Mode” option is different from the “Adaptive Picture” option in the “Eye Care” section? Apparently, nothing. At least when you activate any of these settings, the second one becomes inaccessible.

There is no equivalent for the “Eco Sensor Mode” option for the “Min. Backlight” option (unlike “Adaptive Picture”). Maybe that's the only difference.

Eco Saving Plus

Also in the ”System” settings there is an option “Eco Saving Plus”.

The Eco Saving Plus function reduces power consumption by controlling the electric current used by the monitor panel. That is, if the automatically selected brightness using the “Adaptive Picture” and “Eco Sensor Mode” is too bright for you, then by enabling the “Eco Saving Plus” option, you can reduce it by about 10% if you select the “Auto” option.

Possible options:

  • Off: Deactivate the Eco Saving Plus function.
  • Auto: The power consumption will automatically be reduced by about 10% over the current setting. (The reduction of power consumption depends on the customer screen brightness condition.)
  • Low: Saves up to 25 % energy compared to the maximum brightness.
  • High: Saves up to 50 % energy compared to the maximum brightness.

Notes:

  • This menu is not available when Eye Saver Mode is enabled.
  • This menu is not available when Game Mode is enabled.
  • This menu is not available when PIP/PBP Mode is enabled.
  • This menu is not available when Picture Mode is set to Dynamic Contrast mode.

Picture Mode (Dynamic Contrast)

In the “Picture” group of settings, there is an option called “Picture Mode”. Among its options there is “Dynamic Contrast”. When it is turned on, the contrast of objects noticeably improves, but the brightness also drops noticeably.

The description of this feature says: obtain balanced brightness through automatic contrast adjustment.

How “Dynamic Contrast” differs from “Dynamic Brightness”, which also adjusts contrast settings, is not entirely clear. It is possible that “Dynamic Brightness” sets the contrast settings based on the ambient light of the monitor, while “Dynamic Contrast” sets the contrast value based on the displayed content, that is, what is displayed on the screen.

Which auto brightness option should I choose?

According to my observations, the “Dynamic Brightness” option does not affect the overall brightness very much – at least I did not notice much effect from it, although I keep this option turned on.

There is no fundamental difference between the “Adaptive Picture” and “Eco Sensor Mode” options. But I choose the first option (“Adaptive Picture”), because this option is easier to find in the menu. In addition, enabling “Adaptive Picture” can be programmed to the “Setup Custom Key” and enable or disable this feature even faster.

How to bind the “Adaptive Picture” feature to a “Setup Custom Key”

In the process of using the “Adaptive Picture” function, I came to the conclusion that in low light this is a really useful and convenient feature. But in daylight, I like it when the brightness is set to maximum, even if the day is overcast and the monitor prefers to reduce the brightness a little.

Therefore, in the evening and early in the morning, I use the monitor with the “Adaptive Picture” function turned off, and turn it on during the day. It turns out that I switch this option 2 times a day. This is not much and this action can be done through the monitor options menu. But you can simplify your life even more and bring this function to the “Setup Custom Key” on the 5-way button.

5-way button – this is the joystick with which we enter the menu and move there. The RIGHT button can be customized with a custom action. Next, I'll show you how to enable and disable the “Adaptive Picture” feature to bind to a “Setup Custom Key”.

Go to Monitor Menu → System

Find the setting “Setup Custom Key”, go to this section.

Select “Adaptive Picture”.

Now, to enable or disable the “Adaptive Picture” function on the 5-way button, press the center button, then the RIGHT button once, and then the center button again.

How to get the brightest and most colorful picture on a Samsung monitor

Perhaps, having played enough (and completely confused) in the dynamic brightness options, you wanted to return to the brightest and most saturated picture. To do this, set the following settings:

  • Picture → Picture Mode → Cinema
  • Eye Care → Adaptive Image → Off
  • Eye Care → Eye Saver Mode → Off
  • System → Eco Saving Plus → Off
  • System → Dynamic Brightness → On or Off (I don't see the difference)
  • System → PC/AV Mode → PC
  • System → Eco Sensor Mode → Off
