No Video Signal when input is HDR

  • Hello All!


    I just finished my hyperion setup and everything seemed to be working fine. Then I switched my signal to a HDR signal and suddendly my Raspberry Pi is getting no input to display. The live video feed is blank. When I switch back to regular 4K content the live feed is there and the LEDs display as expected. I am using the Gofanco Prophacy gaming splitter which allows me to enable HDR to SDR. This should solve the issue but it is not. I have tried everything I can think of and in researching I am unable to find anyone else having this issue. I have attached a picture of what it looks like when its pushing a 4K signal vs when it is not. PLEASE HELP!! This is the last piece and my setup will be finished! Thanks!


  • Important Notes

    - Only HDMI output #4 supports HDR to SDR enhancement

    - Downscaling to 720p and 480p is not supported

    - Does NOT support resolution downscaling from 4K @60Hz 4:2:2 to 1080p

    - YCbCr 4:2:2 downscaling is not supported

    - Frame rate conversion (e.g., 60Hz to 24Hz) is not supported


    Have you sent the signal to the display and not to the grabber, is there a picture?

  • So I am using HDMI 4 with downscaling turned on


    I do have it set to 720P as the resolution on the pi so do I need to set it to 1080P? I assume a Pi 3B+ should be able to handle that right?


    So I am using a splitter and it does go to the projector just fine. It happens when my Series X goes to HDR. I also tried running HBO Max and as soon as Black Adam starts it goes blank. The game may be at 4K@60Hz but not the movie.


    If Frame rate conversion is not supported this will never work for PS5 or Xbox. Is that correct?


    Thank you for your help on this!
