Scusa ma i collegamenti che hai indicato non sono affatto chiari... l’uscita video va al tv diretta? Quella audio che chiami “mandata” a chi è collegata? Oltre a questo, hai provato invece che a guardare lato tv con menu nascosti a premere il tasto “playback info” (sul telecomando del 820 è a destra del 9) durante la v..........[CUT]
Si scusa probabilmente ho scritto di fretta, comunque l'uscita hdmi video è collegata direttamente al TV mentre l'uscita audio hdmi è collegata al mio sintoamplificatore certificato atmos, ho ricevuto la seguente risposta su av forum UK :have an LG cx55 and a Panasonic ub820 and really scratching my head on the settings
I have connected the player directly the player to the TV with this hdmi :cable Club 3D CAC-1372 - Cavo HDMI ad alta velocità, 10 K, 120 Hz, surely it should be able to handle everything such as dolby vision and hdr 10.
Nb :Little update, the problem is only with dolby vision, I just tried star wars the rise of Skywalker and the TV is displaying hdr 12 bit ycbcr 4.4.4... Even more puzzled so either I need to change settings for dolby vision on the player or dv is broken on the panasonic or the TV, I have changed hdmi cable too, same result for dv, help

Managed to do a factory reset on both the player and the TV, no luck, dolby vision still at 8bit, did change cable too, I think it's some player setting, no idea which one
This is perfectly OK. The player is outputting DV. The TV will be reporting this in the same way as my AVR does (8 bit RGB). As long as the TV is kicked into a DV mode you don't have a problem.
AVR’s may report DV signals in one of two ways, but both are correct: Resolution: 4k:24Hz ->4k:24Hz HDR: Dolby Vision Color Space: RGB 4:4:4 -> RGB 4:4:4 -OR- YCbCr 4:2:2 -> YCbCr 4:2:2 Color Depth: 8 bits -> 8 bits -OR- 12 bits -> 12 bits

This is called RGB tunneling and it's intended behavior. Basically the DV stream is wrapped in an 8bit RGB signal and sent through HDMI to be unpacked by the TV. This is the preferred way to send a DV signal if the TV supports it (which the CX does) as opposed to the low latency version (LLDV) where your player will do most of the heavy lifting for decoding a DV picture.
