Thanks everyone for your comments!
I am looking for both a 4K TV and 4K Blu-ray player.
As previously mentioned am trying to do my homework.
Have had better results finding info for 4K TVs than 4K Blu-ray players.
Since posting decided to use Oppo Electronics Corporation as a state of art co and found Gene DellaSala's "Oppo UDP-203 & UDP-205 Ultra HD Blu-ray Players Review" "Both the UDP-203 and UDP-205 share critical components where it counts, the video processing and transport. Oppo once again teamed up with MediaTek to produce and manufacture a specialized 4K UHD Blu-ray decoder SoC - the quad-core OP8591, which is said to offer the most advanced image decoding and processing technology available for 4K UHD Blu-ray, Blu-ray, DVD and user-generated media formats"
Googled OP8591 and found "OPPO Digital UDP-205" "... video processing is done with a combination of hardware, digital signal processing, and firmware...The UDP-205 supports all current SD, HD, and UHD resolutions, including 4K at 60p, 4K at 50p, 4K at 30p, and 4K at 24p using various color spaces (e.g., PC RGB, Video RGB, YCbCr 4:4:4, 4:2:2, and 4:2:0). The UDP-205 will also play 4K media files and user-generated content. Decoding support includes HEVC, H.264, VP9 4K, and Hi10P video codecs. High Dynamic Range (the HDR 10 format) and Wide Color Gamut are also supported, and the player includes accurate conversion from HDR to standard dynamic range (SDR) for compatibility with older televisions."
Did find some mention of Oppo going out of business so wonder if MediaTek is releasing the OP8591 to other companies.
