The UB900 have some processing issues, it is messing up croma resolution, and adding croma ringing on 1080P output as 1080P, wich should be a simple matter to handle.. But as there is nobody testing these standard parameters anymore, and just looking on the screen having a subjective opinion, its quite impossible to know whats the best player.. Some serious objective testing of the UB900 vs Oppo 203 would be interesting. Some proper UHD patterns would be needet, along with a reference UHD display, wich might be hard to find.
I haven't seen any ringing, but my UB900, once it recognized that my display was 4K, upscales Blu-rays to 4K automatically now anyway, so it isn't outputting 1080p. When I have Jeff Meier of Accucal here Sunday to calibrate my RS4500, I'll have him test this and maybe I can take some photos of test patterns, if there is time.
A UHD croma multiburst and color pluge should do for the croma test, but you will also have to be sure the display dont have any croma issues, so multiple players and displays are normaly needet to figure out whats what.
I'm only concerned with my RS4500, and I don't have several laying around, so that isn't going to happen - LOL.
If you have a UHD tv you would have something to compare to, and see if it behaves the same.
I do not. I have one 4K display - an RS4500.
Will be exiting to see how that combination handle together.
Jeff knows his stuff, so I'll post up what he says etc. next Monday!
I'm not too worried about 1080p output from a 4k player to be honest. Playing back 4K UHD and 1080p at 4K, the 900 has excellent PQ.Im one of the ones that had a buggy mess with a 203, sold it after 45 days (bought on release day), but they seem to have worked everything out. If you need HDR to SDR 709 or SDR 2020, there is nothing better than the 900 right now.That being said, I currently have a 900, X800 and X1000ES. Love all of em, and the Sony's streaming ability is excellent, especially since it outputs Amazon and Netflix at 2160p/24, not 60. Panasonic did gain a slight edge here, their FW last week enabled HDR on Amazon, Sony has HDR Netflix but only UHD Amazon right now.
