QE55S90DAEXXU HDR on pc not working

[Kaltar93]

So recently got a QE55S90DAEXXU from a  UE49KS70000 as it died from a storm last week so I had to get a new tv,

Long story short, (all work perfectly on old tv hdr wont on new tv neither will 144hz)

- hdr 10+ on old fine on pc and gaming, hdmi to hdmi on gpu, now won't work with new tv, I try turning on hdr in windows I get signal loss message, turn off and pic restores, loading a game in full screen also shows signal loss, turning on and off signal plus has no effect, 

-tried turn gaming mode and intelligent modes on and off, no effect, 

- found reducing refresh to 30hz and 1080p i get hdr to work on windows, but I can't get it to 60hz or 144hz or higher then 1080, 

- any suggestions??

HDMI ports can support different versions of HDCP. If your TV supports HDCP 2.3 and the version on your PC is lower, there could be issues. It is important to note that HDCP 2.3 is only partially compatible with HDCP 2.0 and 2.1. When using a copy-protected video stream, the resolution is limited to HD. If you notice that your TV starts showing low-resolution video after adjusting the resolution on your computer, this may be the cause. For more information on HDCP compatibility versions, please refer to this guide.

Try testing this by watching a protected movie on your PC using your TV as a monitor.
