Monitors supporting hardware calibration modify their own internal LUT and so are not affected by any software messing up with the GPU. Supposedly widowed/borderless avoids this and there are some injectors that fix it, but I haven't got experience with either. The problem with games is they reset the GPUs LUT so you lose your calibration. There is additional information in the ICC profile for color conversion in supporting apps for even better results but I never quite understood how that part works.Īfter profiling and loading the LUT you get a color accurate image on your monitor.

The most important part of it is the LUT that gets loaded into your GPU and does the majority of work to get accurate colors and gama.
