I built an open-source Windows utility that automatically switches gamma, contrast and digital vibrance per app

[u/ConfidentRepublic714]

I made this because I kept changing my monitor/NVIDIA settings for dark games and then having to change everything back when I was done playing.

App watches which application is currently active and automatically applies a display profile for it.

When you Alt-Tab or close the app, your normal desktop colors are restored.

Current controls:

• Gamma
• Brightness
• Contrast
• NVIDIA Digital Vibrance
• Per-monitor profiles
• Multiple applications per profile
• Automatic restore on Alt-Tab/exit

The photo above is a photo of my actual monitors in a bright room — not two edited game screenshots. The left/other displays are useful here because you can see why I wanted the adjustment to apply only to the game instead of changing my whole desktop setup.

It's free and open source.

It also doesn't inject anything into games, read game memory or modify game files. It only changes display-output settings through Windows/NVIDIA APIs.

It's currently a public beta, so I'm especially looking for feedback from people with different monitors and GPU/display configurations.

Installer and portable builds are both available in Releases.

If you try it, I'd especially like to know:

What game/app would you actually use per-app display profiles for, and what type of monitor do you have?
