Hi,

I stumbled on this forum while googling how to get my hdr to work and im hoping someone here can point me in the right direction

When i try to turn hdr on in windows it just gives me a black screen for a sec and turns back off.. no error no nothing. i tried it on different resolutions and only plugging in my tv instead of my tv and monitor and the result is the same .. it just turns on for a sec.. black screen.. turned off

I have a feeling it could be that my motherboard is too old? im using a 1660ti but on a pci x16 slot.. besides that i have no clue why it wont work

my specs are:
Gigabyte GA-Z97X-Gaming 3
Intel Core i7-4790K
Nvidia GTX 1660-Ti 6gb

and my tv is:
Philips 43PUS7304

any help would be greatly appreciated and if more info or tests are required im very willing to provide those.

Update. I managed to get hdr working at 30 hz. But it feels like the colors look wierd. Also why wont it work on 60hz? i bought a 4k 60hz cable .. my tv can run it and i doubt a 1660 ti cant ... so whats the problem here

You're not using an extra-long HDMI cable are you?

I had problems with HDR trying to use a 10m cable once but it was fine when I switched to a much shorter one
 
I managed to get it to work. Honestly i have no idea how exactly.. ive tried nvidia control center before and it just wouldnt let me change anything.. only when i put my tv on 30hz through windows... but it seems now i was able to change it to hdr 60hz in nvidia and after that in windows too...

well not sure how but problem solved :P
 
Wish I knew what you did, lol, I have the same issue. At 4K 60Hz it won't trigger. But at almost any other setting it will. I am not sure whether it just doesn't work at 60Hz or whether there is something wrong with Windows.
 
what i did was turn my tv to 30hz in windows settings.. after that i was able to select more settings through nvidia control pannel.. i played with that for a bit (accepting the settings at different hz and color depth format and range ) randomly at some point i was able to choose output color depth 12 bit?????? that disapeared quickly ... anyway after accepting those settings i went back to my windows and turned on hdr there.. which it accepted at the 30hz settings from nvidia panel.. then i think i just changed my hz back to 60 in windows... and it just worked.

I know this isnt a super helpful guide... but.. computers are strange sometimes.. it almost feels like nvidia control panel somehow forced windows to detect the screen better.

hope it helps :)
