Windows 10: Screen brightness dims the moment i open the 2nd program/application

Hi Community,I encountered this annoying situation where my screen is automatically dimming the moment I open the 2nd program/application.I always keep highest brightness setting. This dimming is not what i expect. Hope this is just a software glitch. Any help? Thank you!

Screen dimming even at 100% brightness

Hi recently bought a Lenovo laptop, a Lenovo V14-ARE laptop, and as soon as I turned it on I noticed, when I put it on 100% brightness it is bright and vivid but then it dims. After a while, the screen brightens again then proceeds to dim once again in a
few seconds. When I plug it in to charge, the screen is bright and vivid but as soon as I unplug it, it dims. I already left clicked on the power icon in the task bar, went to power options and selected "choose when to turn off the display", clicked "change
advanced power settings", scrolled down to "display" and opened its list, but the only option I have for the display's list is "turn off display after", in the Youtube videos I've seen they have an "adaptive brightness" setting or something like that and that
fixes their problem but I don't have that option. My power plan is also in high performance and everything is "on battery" but the problem still happens.

Can this problem be fixed?

 

Screen dim when using some program.

Hi,

It is happening for a long time now. I start to get annoyed with the screen dims whenever I change to a different program.

Example;

• When I'm using Movie & TV to watch a video that I downloaded. In the main menu, the screen was bright. But then it starts dimming when I want to watch video fullscreen. I opened the
  Action Center to change the brightness but its already on 100%.
• The program that I frequently use is Avast Secure Browser (preferred browser) is bright than the other program like
  Desktop Telegram (even in a restored window) then it starts to dim.

My eye starts to get hurt by seeing the screen changing brightness frequently (especially in the dark). I tried to find a solution but could not find any. even though this is a small thing. But it makes me less productive when I am making music. I tried
restarting my laptop multiple times already but still did not solve the problem.

A laptop that I'm using is HP Revolve 810 running Windows 10.

 

Very dim screen, lack of brightness.

windows 10, Samsung laptop

After computer unplugged for about 5 hours, but turnedoff, and then when turned back on and plugged in again screen very very dim. Battery is charging, up to (93%), brightness set to 90% but display very very dim. Should I not have full brightness the moment
computer was plugged in again after having been unplugged for some time?
