Xbox Series X No 4K HDR on a 4K UST projector

When i connect the Xbox directly to my projector 4k HDR 60hz game play is supported and works. When I pass through the Sony receiver 4k HDR 60hz gameplay is not supported. The Xbox says going through a receiver may limit support. But, the PS4 and my gaming
PC support 4k HDR 60hz gameplay passing through the projector. Just seems strange that the Xbox doesnt support this receiver. Makes we worried about future Series X compatibility as well...

Finally, I took my Xbox one s to my friend's house and connected it to a 4K OLED TV. And I can see the 4K and HDR signals working fine. I used the same HDMI cable that was connected to the 4K projector. But when connected back to the projector and selected
the option Allow 4K I see the message the TV doesn't support 4K. But Allow HDR is fine on the Projector. I don't know where the issue is. The projector seems to work fine with Apple TV 4K, Firestick 4K and nVidia Shield TV with 4K HDR signals. The issue seems
to be with the Xbox the way its detecting the signal on the TV.

Pro-Tip: Instead of a 4K HDR TV, get yourself a 4K HDR projector and a huge projection screen.

You'll be able to set the output of the Xbox One X to 1080p, and if a game supports HDR then the console will use it, I mean the Xbox One S supports HDR, so no reason why the Xbox One X would only allow it at 4K.

Thanks, I hope that is the case. The S will not allow HDR unless output is set to 4K. Not to tout the PS4 Pro but it told me my projector would not support HDR in 4K but offered up "2k HDR" as an option. I would hope the X was as elegant.

Here I am a year later with the same issue, different projector. Using the Optoma UHD51A and I can watch 4k HDR movies from a 4k blu-ray disc, but the X-Box says my system is not capable of 4k HDR gaming. So, still no fix eh?
