I have been searching but cant find a proper answer.

So I have a PC attached to a new Hisense Q8G 65" 4K TV. But when I go to select HDR in Windows display, it just auto turns off. I have it connected via a new Display to HDMI adapter and a new HDMI 4K compatible cable. Yes, it is Windows 10.

I may have found the answer:
It turns out. HDR will only enable if your Graphics Card or Motherboard has HDMI 2.0 or newer that supports HDR10.

If you're using DisplayPort to HDMI 2.0 Adapter. It won't enable HDR10. Because, the Adapter use DisplayPort 1.2. Which means DisplayPort 1.2 does not support HDR10. Only DisplayPort 1.4 or newer support HDR10.

If Anyone is interested for future info, I got it working.

I first just decided to use HDMI port as Display port on GTX 970 is only 1.2. Second, I had to switch in Nvidia settings to custom color and what not which I set it to Chroma 4:4:4 and limited Dynamic Range. Then I had to set on my TV HDMI 2.0 to "Enhance" mode in order to get it to just enable it. What a pain.

Well done, I would have thought HDR needed a newer GPU.
Good to know it works with older stuff.
