Hi George,

Welcome back. Mark H posted this in another thread:

Now that we have UHD players, I'm sad to say that even though I could pass other 4K sources I have been unable to pass UHD discs. Fortunately the [panasonic] player has two HDMI outputs and so the video goes direct to the video chain and the audio goes through the HD621.
Interesting thread here on HD621 Does it support 4K?
