Question

Windows 10 + NVIDIA + HDR

Hello,
I am able to play a videogame on PC with HDR thanks to my UHD TV and a 2.0 HDMI cable I purchased, which would be awesome... however my PC has an Nvidia GTX 970 videocard, and Nvidia's newest Updates completely screwed up the color profiles/brightness of Windows and thus every videogame is much much darker on default(Lot of people has this problem), The problem also persists when I play HDR content, it is very dark.
I can play around with the windows color settings, however I cannot get it right. Raising brightness does nothing just makes the picture washed out. Raising the Contrast and Gamma settings however would make things better. My problem is I cannot figure out the correct ratio of gamma and contrast to have a crispy yet bright-enough looking image (either washed out in ways like blood looking like tomato juice, or too dim).

My question basically: Is there any "correct ratio" of how Gamma relates to Contrast? Like, if i raise gamma this much I should raise contrast that much, related to it? Is there a chart, or something?

Actually

If you research this the common complaint is dull and such colors. Most folk try it then go back to not-HDR.

You are traveling a well worn area.

Not the problem

No, actually I am watching UHD HDR content on a Blue Ray Player connected to the same UHD TV and I have no problem with those. Those are nice and bright. I only have this problem with the videogames on the PC, it is because of an update that screwed up things with Nvidia graphics cards....

Another thing

Another thing with this though: In the videogame(It is MK11 btw)-s menu there is the Gamma adjust scale. It says 'Adjust Gamma Until Only the Right Dragon Logo is Visible" and there are two logos one darker one brighter. In SDR mode, I can do it so the left one is invisible, and yet the picture is bright enough for my preferences. In HDR, it only disappears if the picture is very dark.
Should that be taken into consideration, or that logo,and that gamma adjustment is only for SDR mode, and with HDR both logos are supposed to be seen as HDR is supposed to show more details in the dark areas(thus showing the logo because it is different color than pitch black)?
