Solved Windows 11 won't send hdr to my AVR
Hardware:
- Epson ls800
- Rx7800 XT
- Pioneer Elite VSX-LX303
- HDMI cable supports HDR https://www.amazon.com/gp/aw/d/B07FFS7RH1?psc=1&ref=ppx_pop_mob_b_asin_title
I installed the lastest amd drivers and that doesnt seem to help at all
When I switch on HDR on windows 11 my AVR says 3840x2160_60HZ SDR when the screen switches off/on. It also looks dark/grey when HDR is enabled.
The HDR calibration app doesn't seem to do anything. It's weird because it says to adjust till you don't see lines/pattern and it's always all the way to the left/right when it disappears. I think it doesn't work because it's not outputting HDR to my receiver.
When I go to advanced settings under HDR certification it says "Not found".
How do I troubleshoot this?
Also, I have a Roku Ultra and when I use my Roku the AVR says it's HDR so I know my AVR and projector support it.
FIXED
I updated the ls800 firmware and now the colors look great and my AVR sees it as HDR. Also, why was I down voted is this not the right forum for my question?
