I have serious reservations about doing a factory reset, which would wipe my identity from the TV and cause me to have to sign in to all of my paid subscription accounts (No simple feat). Netflix, Youtube, and Prime Video alone are daunting challenges and they are just for starters.
As it stands, the troubleshoot quide in the TV no longer mentions anything about 8K input (where it use to) and there's no indication it is currently supported.
The TV allowed a few moments viewing of content from the AVR before blanking the screen and declaring the 8K signal an "UNSUPPORTED RESOLUTION".
It had no issue with the signal up until the firmware update, so I checked the specific signal it was having an issue with,
It turns out the TV says it was receiving a resolution of 7680X4320 (which shouldn't be a problem) But ,it receiving it at 24P and not the expected 60P.
I'm not sure how that could happen since the Denon hardware dosen't have that in it's list of options.
Either way, I went into the Denon Settings and changed the "Video/Output setting" option -Resolution (HDMI) from Automatic to 8K.
I then changed the "4K/8K SIGNAL FORMAT" in Denon's settings panel back to 8K.
I don't believe they plan to ever fix that. (hardware limitations).
While the screen is excellent for 8K images, the internal apps simply cannot send 8K signals. Instead, we, as end users end up buying an 8K capable device and connecting it to HDMI 4. Playstation 5, an 8K capable home theater, or some other device that can send an 8K signal. The same applies to atmos.
If you want it, the easiest way to get it is with some other device connected to a Atmos capable home theater...and the screen is just that...only a screen. A very good one.
