Windows 10: Monitor screen dims when watching video on fullscreen using PotPlayer

So whenever I watch a video on PotPlayer on fullscreen it auto dims after a few seconds.This problem doesn't occur on Windows 10 default media player.

I really like this player compared to the default windows player so is there a solution I can fix this.


Yes I also checked all the power setting and it's on high performance and no auto dimming whatsoever.


Tq.

Black screen when playing video fullscreen in Windows 10

My Laptop has dual graphic card:Intel HD Graphics 530 and GTX 970m and I usually connect an external monitor to it, setting external monitor (noted as Monitor 1) as main monitor. Both monitors are on. But these days I found that when I play video fullscreen on chrome, the monitor will turn to black but audio goes on, ie. my computer cannot render video correctly. I tested several times and got some info:

1. When I set Monitor 2(internal monitor of laptop) as main monitor, the video is ok when fullscreen, no matter which screen you drag the chrome window into.
   
2. When the HD 530 is banned in Device Manager, ie. only GTX 970m working, it also works well.
   
3. I tried disabling Hardware Accleration as some solution instructed but seems this issue remains unsolved.
   
4. Playing video file (.mkv, .mpeg, etc.) with video player (Windows video player, Potplayer, .etc) never meets black screen.
   
5. Rolling graphic cards' drivers back has been tried but not working.
   
6. Edge as well as IE has same problem as chrome, so I guess the real problem is about video cards indeed.
   

Addition:

I seem to recall that weeks ago when I played web video fullscreen on Monitor 2 (which is not main), Windows crashed and went BLUE SCREEN. Though if Monitor 2 set as main the error would not occur according to my tests.

I really want to know why and how to fix. Thank you.

Screen dimming and video playback issues.

Hello! Recently my laptop has been having some issues. I've noticed that now-a-days whenever I put my laptop in charging, the screen brightens, and when I unplug it, it dims. I've also seen a similar thing in video playback. Whenever I'm watching netflix,
or just even a video, when I go into fullscreen mode, the screen brightens and dims frequently. It flickers. This issue hadn't come up before and now it is, I've updated my graphic drivers, and I've searched a lot online, I couldn't find any solution. Some
help would be really appreciated, thanks!
