I seemed to have found a scary issue with the 820 and my 4K SONY VPL VW385ES that presumably started after I installed the last firmware update yesterday. I have been very happy with the 820’s tone mapping and use the SDR/BT.2020 mode.
I have people coming over for movie night on Friday night and was checking some setting in the SONY menu while playing the 4K UHD movie I will be showing, Black Panther. In the SONY menu I notice that the display was 3840x2160/60p YCbCr 4:2:0 BT.709, when I was expecting 24p and BT .2020. Why the 820 was now outputting 60p instead of 24p, I don’t know. My SONY 385 can handle 4K60p, but not with full bit depth, plus I like to watch movies with the correct cadence, so this was not good. Panic!
The resolution setting on the 820 was 4K and I tried to set the 4K60p output mode to Off, but that forced the resolution to Auto (1080p). I was trying all combination of setting to try and get the UHD BT .2020 24p back working, but seemingly with no luck, so I decided to watch a bit of the movie see how bad the BT 709 mode looked. Not bad I thought and brought up the SONY Menu only to find that I was watching in 3840x2160/24p YCbCr 4:2:2 BT.2020, which of course, was what I had been expecting from the beginning. Now the 820 settings menu listed the Resolution as Auto (4K) not Auto (1080p). In this mode that I seemed to have somehow achieved, the 820 menus are 1080/60p BT 709, but when I start the movie, it is UHD at 24p and BT .2020. This does seem cause a bit more projector syncing delays when going in and out of the menus, but at least I know that there is a mode that works for Friday's Movie night. It must be in all my setting changes I finally convinced the 820 that the projector could do 4K properly at 24p. I don’t know, but it had me concerned for a bit. Comments appreciated.
