Flux color calibration problems

[rkrisi]

Hi everyone!

I have reinstalled windows on my computer, and after installing flux, my main display (LG 34UM58, connected on HDMI) became a desaturated, colorless screen. My second monitor which is connected via DVI has no problems.
Previously I had the same issue with this display and flux but unplugging and plugging fixed this problem. Anyone experienced something familiar? Or knows a solution for it?

I'm using the latest version of Flux, and Windows 10 Pro 64bit (AMD R9 280X)

Thanks,

Kristóf
