Windows 10: Screen changes brightness according to level of white on the screen, only when connected to...

So, I have just discovered this issue with my Acer Aspire 3 laptop. I shattered the screen, so being a broke college student, I decided to just connect my laptop to my 42" Samsung Smart TV to use as a monitor. Everything works fine after adjusting some things with audio issues and only showing the display on the TV, except for one single thing, and it's infuriating. Based on the level of white on the screen, or I suppose the relative level of bright color displayed on the screen as a whole, the entire display will instantly dim or brighten accordingly. Now, say, this would be okay if I didn't play video games on my laptop or use dark mode on any of my apps. but I do both of those things. For reference, this has never happened on the laptop display on its own, and I have also looked for as many possible display and power/eco/smart-saving settings on both my laptop and TV, and none of them seem to fix this. It's almost incredible how rare this issue seems to be on the internet, given the lack of simple fixes for this issue. However, any help would be greatly appreciated, because there is NO WAY this isn't a setting somewhere for something. My Xbox One has used this TV with no issues for months now. Thank you in advance.

Change screen brightness

My laptop screen is dull. Need to make it brighter. However the suggestion --> Start - Settings - System - Brightness and color

does not work. It is already set to max. brightness but there is no reaction. Screen remains dull. By the way there is no change if I move slide to minimum brightness, it would not change brightness level at all. Any suggestion?

 

Screen brightness change automatically

Hi,

Thank you for writing to Microsoft Community Forums.

I understand that the screen brightness change automatically while watching videos.

• Are you aware of any changes made to the PC recently?
  
• What is the model number of Lenovo Yoga PC?
  

Windows 10 has the ability to automatically adjust the screen brightness depending on the ambient light levels. This feature can be more annoying than helpful, either leaving your screen too dark or frequently
adjusting the brightness levels.

If you are using Lenovo YOGA 3 Pro-1370, I suggest you
Disable auto brightness feature
and check if it helps.
