a little help calibrating hdr on optoma hd27hdr

I would start by ensuring that your nVidia settings are correct as that's the most likely culprit. It sounds like the games are not playing using proper HDR or aren't compatible with HDR.

HDR changes the way that white levels are handled by the display. So, if you have your display setup for HDR and are sending 10-bit color to the display with a HDR tag, but the video isn't actually using the proper mapping, then you will end up with whites which are in the HDR range, when they should just be normal 'white'.

Sounds like the projector is crushing whites because the game or video card isn't actually pushing HDR10 content out.

There is a ton of Google information on nVidia cards and HDR available to look at.
https://support.microsoft.com/en-us...> System > Display,dxdiag, and then select OK.

The Optoma certainly accepts HDR10 video, but it sounds like that's not what you are feeding it.

PC issue, not a projector issue (it sounds like).

Don't send 12 bit, set your pc to 10bit 4.2.2. Yes out of the box the hdr is way overblown. Put your brightness setting at -8 and set the contrast to -3 or 4. Use the details setting also. Try that. Or another thing to do is, find a scene that has a sky in it and turn down the brightness and contrast till all the detail cones in. I used the meg movie where he pulls up to the small dock right after he rescues the mom and he reunites her with the daughter. The platform they pull up to with the small boat had zero detail in it. Just a blown out white blob. I dialed that in with that scene.

Cool thanks for the input I'll try that out , btw that's exactly what I'm talking about that white blob either in the sky or any bright scenes which is way too overwhelming and you can't see nothing in, I think I set the HDR mode to details
and lamp settings to dynamic now too
