Why does my screen go black when I Alt Tab in Windows 11?

If your screen goes black when you press Alt-Tab keys, below are some possible triggers:

Incorrect display settings – If your monitor is not set with the best display settings, it may lead to a black screen issue on your Windows 11 PC.  Corrupt/outdated video driver – If you’re using an outdated video driver or there is some corruption in it, it can also cause this problem on your PC.  Wrong keyboard settings – If your keyboard settings have been changed or you’re using the wrong keyboard layout, it can cause this problem. Too many programs – The more programs that are running, the longer it takes to cycle through them all and show them on your screen. Wrong key combination – You may have accidentally pressed the wrong combination of keys on your keyboard. Virus infection – Some malware or virus may be installed on your computer, causing this problem. Old GPU – The GPU is responsible for displaying graphics on your screen. If it’s not powerful enough to handle high-resolution games or apps, then it can cause this issue. Low memory – If your computer has low memory or RAM and needs more resources, it will temporarily suspend other apps running on the system while loading up another one hence the black screen issue when pressing the Alt-Tab keys. App conflicts – You may have installed an application that has a hotkey that conflicts with your keystrokes.

What can I do to fix my screen if it goes black when I press Alt Tab?

A few workarounds that may work before you attempt the technical solutions include:

Ensure that your power cable is connected properly and that there are no loose connections. Try unplugging the keyboard and mouse from their USB ports and plugging them back in, preferably in different ports. Unplug your HDMI and plug it back in. Also, try with another HDMI cable if available. Close all unnecessary applications. The more programs you have open, the more memory they take, causing your computer to slow down significantly. Using RAM cleaners, ensure your PC has enough RAM to run multiple programs simultaneously.  You can always add more memory if that’s the issue. Uninstall any programs that you’ve recently installed on your computer, and then try using Alt-Tab again. Check that your operating system is up-to-date.  Refresh the video driver using the Windows Key + Shift + Ctrl + B shortcut.

1. Adjust your refresh rate 

Your refresh rate is the number of times per second your display refreshes itself. The higher the refresh rate, the better the response rate for your screen. Keep in mind that higher refresh rates work better with powerful GPUs.  If your GPU is an old one, it may not be able to keep up with the speed and may give birth to more problems, such as screen tearing.

2. Change your graphic settings 

Note that if the screen goes black when you press Alt-Tab, it’s also possible that your system cannot handle the game’s graphics requirements. Instead of selecting high performance, you should let Windows decide.

3. Update your graphic drivers

There are many methods to update your graphic drivers manually, but some of them are too complicated for the average user. This is why we recommend using a dedicated method like Driverfix. It automatically scans your computer for missing and outdated drivers, then downloads and installs these updates for you.

4. Run a virus scan

A black screen on your Windows 11 is nothing strange, so you must be prepared whenever it occurs.
