As for other settings:
I have 4K output set to 4K(50/60p) 4:2:0. I didn't notice any banding on my TV with 4:4:4 but I switched to 4:2:0 all the same. From what I understand it is also of no use to select 4:4:4?
I have selected YCbCr (Automatic), is that correct or should I choose YCbCr (4:2:2)? The disclaimer says that when 4:4:4 is selected during UHD playback, the player will still output in 4:2:0 anyway.
I have Deep Colour Output set to off as it is my understanding this option does nothing in particular.
Also under sound options, I have set Dynamic Range Compression to off.
I'm the type of person who wants to keep unnecessary and unwanted processing to an absolute minimum unless the PQ really does benefit from it. I like my picture (and sound) as untouched and pure as possible, the way it was intended to be seen.  |
The chroma sharpness affects UHD as well as BD, whereas the Edge Correction doesn't make a difference with UHD unless you really push the sharpness all the way out (seem my link to the Oblivion thread above).
But while the chroma sharpness generates obvious vertical and horizontal ringing on colour bars (behaving similarly to the chroma enhancement feature on my older Panny BD player) it's not something that's obvious during live action content so I changed my chroma from -3 back to 0, whereas on an animated feature the ringing may become more obvious so I'll tone it back down as and when I need to.
As for the 4K50/60 setting, I would advise changing that to 4:4:4 otherwise you won't get any HDR WCG playback from 4K60 content, as by setting it to 4:2:0 it automatically downrates 4K60 material to 8-bit SDR 709. Not so much a problem now, sure, seeing as there's only one 60fps movie disc (Billy Lynn's), but I'd set it to 4:4:4 all the same if your TV can handle full-fat 4K60 content. Mine cannot, so it automatically set the 4:2:0 4K60 output during initial set-up.
I've left Deep Colour on, it does nothing to the UHD 24p output which is 12-bit 4:2:2 anyway, but upscaled Blu-rays look a bit more polished in 12-bit 4:2:2 than 8-bit 4:4:4, as the latter is what the player will default to for BD playback if I turn DC off.
