When I press Alt+Shift and Ctrl+Alt my screen changes contrast/. Ctrl+Alt sets it to "Default" while Alt+Shift cycles between "Normal", "Light", "Contrast", "Bright", "Vivid", "Intense", "Dimmed", and "Opaque".

I have no idea what caused these hotkeys to start behaving this way, it's been this way for as long as I can remember. I just can't stand the behavior any longer and want to make it stop. Any ideas?

  • Check your graphics card/video adapter options for disabling hotkeys.

  • I looked in the NVIDIA Control Panel for hotkey settings and couldn't find anything.

  • It's not a default Windows setting, so has to be something extraneous like (driver) software.

This issue was caused by a program called "Game Companion" which I had previously used to force games that didn't natively support borderless windowed mode into that display configuration. It was running at startup and had hotkeys for gamma adjustment.
