Windows 10: Windows switching from one monitor to another when alt tabbing from a full screen game or...

Hello,


Since several years ago, and that on different computers, I keep experiencing an issue where different applications opened such as Google Chrome, Microsoft Office, Microsoft Teams, Windows Explorer, etc. will switch from one monitor to the other or the size of the windows will change randomly when :


- I alt tab from a video game in full screen mode back to my desktop

- I lock my session and login again


I use a main monitor with a resolution of 3840x2160p or 2560x1440p

I use a secondary monitor with a resolution of 1920x1080p


Is there something that can be done about this?

Thank you.

:)

 

Is alt+tabbing bad for your monitor or TV?

Well your monitor will only go on and off from Alt+ TAB if you are switching from an odd resolution to the desktop resolution.
Also you could just windowed borderless.

 

What is the "magic" of alt+tab?

What about using alt+enter to ensure you're full screen, or switch to window and back instead of alt-tabbing to desktop?

Can't recall a game I've played having any issues like what you're reporting...but I do recall using alt+enter to go full screen, still use that from time-to-time when a game launches incorrectly or launches with first run settings. I'm curious to see if only alt + tab works for you or if alt + enter works as well...

 

Weird alt-tab out of fullscreen games.

Hi Simon,

The multitasking capability of a game depends on the total memory of your computer. If you have large amounts of RAM on your computer, it can multitask heavy programs easily like high-end games. To ensure that we can provide the appropriate resolution
for your concerns with the alt-tab function, we’d like to ask you a few questions:

• What were the recent changes made on your computer before you experienced this issue?
• When did the issue start?

• Have you pressed the alt-tab key during you play Rainbow Six Siege? Or it just happen without pressing it?
  
• Does the automatic ALT-TAB behavior happens on other games?
• Do you have any other programs running on your computer while playing?
• What is the anti-virus program you're using?

• What is your device or system specifications? To know, follow these steps:
  1. Press Windows + S and type
     About your PC.
  2. Send us the information listed under Device specifications.
  
  

Moving forward, if you're multitasking while playing, we recommend that you play this game only without doing other tasks. Pressing ALT-TAB or performing a multitasking interferes with the performance of your video card, especially if you're running a heavy
game like Rainbow Six Siege. It will generate screen viewing issues like intermittently switching your game screen between your desktop environment.

For now, restart your game and do not press ALT+TAB while playing. This will allow your video card to dedicate its graphics performance on the game only instead of your desktop environment.

If you would like me to provide additional advice, simply respond to this thread. I will get notified and I’ll reply to you as soon as I can.
