4k channels don’t work on Samsung UN65MU8000F
I have a Samsung UN65MU8000F (4K HDR) connected to 4K genie mini, and switching to one of the Directv 4k channels (105, etc.) causes the picture to go black and the tv to think it has lost the hdmi connection. All other HD channels work fine. I have a different, slightly older Samsung 4K tv (not hdr compatible) in a different room on a different 4K Genie mini, and it is able to view the 4K channels just fine (obviously not in HDR, though).
Things I have tried:
- Updating TV firmware (thought for sure this would fix it because I read somewhere that the Directv 4K HDR broadcast uses HLG and that a software update was required for HLG compatibility
- Ensured settings>general>external device manager>HDMI uhd color is on
-Game mode on
Interestingly, the Guide seems to correctly detect the 4K HDR capability of the TV because I can see “4K” and “HDR” logos next to the titles in the guide. The other non HDR tv only shows “4K” in the guide, so all of that seems correct. I initially thought it was just an HDR problem because I tried the Olympics broadcast in HDR but later realized all 4K content has the same issue... even A Directv cinema 4K movie that views fine on the other tv.
4k content works fine from other sources, for example Prime Video (have not confirmed HDR because I’ve had trouble finding HDR content through Prime Video).
I called Samsung - they said it was a Directv issue. I called Directv - they said it was a Samsung issue.
Has anyone else experienced any similar issues? Is there another HDR or 4K setting somewhere for the UN65MU8000F other than those tried above that I may be missing?
All very frustrating because I spent more for the HDR and can’t even watch 4K much less HDR!
