Ok let's call it UHD. And, sorry, but the HD621 does pass UHD just fine for me. As above, tested with Oppo 103 upscaling and via Himedia Q10 with genuine UHD material,
including Joe Kane's UHD test patterns.

As for those looking for a 2.2 solution into the HD621, lookup KD-HDFIX22. It should provide the solution were looking for, and indeed those with a 2.2 source could verify that it does...

If UHD is a problem via your HD621 there must be something "wrong" in the chain...
