I only receive projector only. i am still selecting projector screen for it. only has a preliminary testing on it by projecting on the wall. If the video is 4K 60p (4:2:0) , it will have banding problems especially the banding is so obvious on some bright sky scene . When set the output of media to 4K24p . the banding seem to be solved. I test it with Nvidia Sheild TV
i also test it with Panasonic Ub900
I found thayt another method seen to be able to solve this banding problem with UB900 The user can set 4K60 output settiing Of UB900 to 4K60p(4:2:0). In this setting, Panasonic convert all 4K60p video to 4:2:0 8bit and Panasonic will automatically proceed dynamic contrast conversion process and and color spacing will automatically mapping to 709 rather than BT2020. In this process. UB900 can output the picture very close to HDR contrast but keep with 60p . Moreover, when a 4K24p video is detected, UB900 will automatically switch back to 4:2:2 12 bit HDR output. I think it is temporary method for user which can enjoy 4K60p video without or less banding picture issue
I will bring to my friend home, i will test it again with a proper projector screen on coming Sunday
