Windows HDR Really Dull With No Contrast

[Steo]

Hi. I got myself a Panasonic 50ex700b TV mainly for the new Xbox one x when I get it. I know it isn't the best TV by far but it's pretty decent for what it cost me and I'm not exactly rich. Anyway when I try to turn on HDR in the windows settings I get a really dull picture where it looks like the contrast is turned right down and the brightness is turned right up. I tried it with my ps4 and gt sport and that looks very bright so I was wondering is this just a problem with windows has anyone any idea? I'm new to trying out HDR so don't really know a lot about it yet. The pc looks fine in normal sdr so it's not the TV itself or the cable.

Make sure settings any not altered

 

If that does not work try different tv

I have it on 10 bit and 422 and the tv says it's pq hdr. The ps4 is bright though so I'd imagine the tv is ok. I have an LG tv in my sittingroom that I can try it on just in case.

Had this issue myself with a Sony KD-65A1 and a GTX970. Went to Nvidia Control Panel and Adjust Desktop Colour Settings. First thing to do is turn the Hue to 0, you should see a marked difference. I then checked Use Nvidia settings and using various images on a split desktop, tweaked the sliders until I was happy. For me this has worked a charm, hope this helps.
