where do you get this information from ?
there are several major reasons why at this point in time the current model panasonic 4k bluray players are probably the better choice for people with higher end 2k HD displays (both the 3 new inexpensive panasonic models, as well as their initially released 2 premium models afaik
- they convert 4k YCbCr to 4k RGB before downscaling it
to 2k HD output for older 2k HD displays (like our sony w900a's) . this maintains 2x higher chroma information and allows a significant amount of the HDR luma information to be maintained when it is converted to a SDR signal (which is important for both non-HDR 4k displays, as well as for our 2k HD displays)
- they dont have the "chroma bug" error (which most other 4k bluray players released before end 2016 did have, including the samsung models, but not the oppo 4k)
one additional point in favor of the new less expensive panasonic 4k players (the 300 and 400 series models) is their ability to choose a manual setting for 10 bit and 12 bit video output. point being: 10 bit video in YCbCr is on the 4k disk, and many pre-2016 tv models cant cope well with 12 bit video being sent to it over HDMI (not sure about our w900a's either), even if it accepts it in the handshake, and will cause banding and posterization artifacts as a result. much better to send clean 10bit RGB to our w900a displays ( even if internally our w900a's might then still process it in 12 bit software). see
btw, the above points are exactly what i posted speculatively about a few months ago in this thread,
to try and send a high quality 4k to 2k converted signal to our w900s's to maximize the video signal allowed under the 2k HD technical standard (10 bit RGB deep color with maintained high chroma and luma values from the original 4k bluray video source by doing the right conversion steps in 4k
). panasonic (and potentially oppo, once it fixes its many bugs with firmware updates), is the only bluray 4K manufacturer that has done this right so far.
not sure why you would want to pre-order the new sony 4k player before it is confirmed it can convert UHD rec2020 color space to rec.709 x.v.Color for HD displays. if it does, great ! but if it doesnt, i cant see the point (other then integrated sony remote controls perhaps)
