Hi, I recently built a gaming pc and I have a HDR tv but it looks washed out. I have a 1080ti graphics card and HDR on windows 10 is set to on. On nvidia settings my desktop colour depth is 32, output colour depth is 12 bit and output dynamic range is limited. It won't allow me to put it to full which is strange as my ps4 allows me to. Watching hdr movies has very washed out blacks, almost like grey and hdr games also look washed out. Is there any settings I should change? I 'm using a sony xe90 tv so it should be goof for hdr. A link to my tv is below, thanks.
