Right now, playing AIW, I am getting HDR Bt2020 4:4:4 10bit 24P and all looks well but with the Sony X700 the UHD50 was showing the same but 12bit. The Dynamic Range Optimizer really helps in producing an overall, seemingly brighter image, but with no loss of highlight or shadow details which allows me full advantage of my low gain ~145in grey painted screen. Also in Canada, it has a Prime Video 4K HDR streaming app which is nice as this was lacking on the X700. Our current plan is to move the Sony X700 to one of our other residences, in the US to take advantage of the X700's much larger suite of 4K HDR streaming apps down south.
Some initial impressions are that the UB420 doesn't upscale 1080p content to 4K as cleanly as the X700. Also the interface is less well laid out than on the X700 and the UB420's remote is truly terrible, as the non-back lit, 4-way selector, is tightly surrounded by curved buttons, that if accidentally pressed, will pull you completely away from whatever option you might have contemplated using... OTOH, it has a powerful transmitter that easily bounces off the screen to control the UB420, which is located behind our seating position.
Edit: The UB420 is definitely a step up in terms of HDR output and I think it'll be well worth the cost. I'll try and take some comparison photos in the next few days but it's tough to do a side by side with the X700 because the UHD50 only has a single HDMI 2.0 input.
OK, I got the UB420 UHD BD 12bit 4:4:4 24P working:
I set 4k/60z to 4:4:4 (from auto)
Edit: ycbcr is auto (if set to 4:4:4) HDR fails on Netflix. However everything is playing at 60hz. 4:4:4 8bit. My x700 will play Netflix 4k HDR content at 24p, 12bit 4:4:4.
Deep colour is 12bit(auto) which is optimal for HDR BDs but results in posterization with Netflix. Setting Deep Colour to 10bit results in 60hz 10bit 4:2:0 and much superior HDR and no posterization.
I have the HDR Optimzer set to projector and: 'light room' with brightness at 0, tone curve white at -3 and tone curve black at +3. On some streamed 4K content I set tone curve white at -9. The ability to use the HDR optimizer whilst streaming 4K HDR content is a very nice feature.
These settings produce a brighter image but keep the highlights from blowing out and prevent the shadows from getting too blocked up; of course the HDR Optimizer settings will be somewhat room specific.
The UB420 has some nice audio features for us condo dwellers that I didn't notice on the X700, especially a dialogue enhancer which makes voices easier to hear at low volume settings and a night mode to keep the sound effects from getting too loud.
The UB420 audio enhancements really boost the quality of the stereo speaker output in the UHD50. If you're in an apartment or condo, the UB420/UHD50 might be all you need.
