I got my UB820 on Sunday, and after fiddling with settings last night I finally got it to output right on my Samsung Q7FN 65". It will correctly send sound via audio out HDMI to my Denon X4500h and correctly sends the picture direct to the TV via video out HDMI (since the Denon won't pass through HDR10+).

Super High Luminance LCD (Q7FN has peak brightness of 2268 nits, so perhaps this should be set to OLED even though it's not an OLED panel?)

All hunky dory. But now I'm trying to setup netflix and screen goes blank. I press the internet button, navigate to Netflix, press ok on the remote and the screen goes blank. 'NET' does appear on the front of the player but no picture. I've tried turning the TV off and on again in case the TV isn't recognising a change in video signal, but no, doesn't do anything. I press home to try and get back but to the home screen but still no picture and LCD display still says 'NET'. Tried the open/close button to check it isn't a menu thing that I can't see to accept (e.g. 'are you sure you want to quit'), but that won't open the drive. Only when to rescue this is to turn the panny off and back on again.
As well as the things mentioned above, I've tried switching from wireless to ethernet in case it was something odd with the network but that doesn't help either. I had a search for 'crash' in this thread and couldn't find anything so perhaps it's only my unit? Have checked firmware update and that is all up to date.
For netflix the above happens, can't even get to login page
For Amazon Prime the app opens and I could log in and browse, but if I try to play anything I get the spinning loading icon for 30 seconds or so and then a pop-up of 'Something went wrong, please try again later'
Anyone else had this?
