Description

I am using the precompiled version for WIN I got the following issue Unable to save current gamma ramp. Failed to start adjustment method wingdi.

I am a developer of simillar app and setting windows gdi was working in previous builds of win 10, I am sure. I was wondering wether other apps solved the issue. Maybe you know wingdi api better than me and you will be able to find the solution. duplicate screen is working, independent screen is working. it will be something about the two screens in extended mode.
