Color space which setting to select?

[DMD]

I had a problem with OFW 2.1.7 also for other stuttering issues video via lan (file UHD 95 Mb/s).
After resetting the box I installed OFW 2.1.7 and then the CFW 2.1.7, I solved both the video stuttering problem and the artifacts of the color space.

So these issues on OFW 2.1.7 may present for others as well... Needs further investigation. This PQ issue you had is called "banding" BTW.
I will do the S&M banding video test today, but I'm only able to do on 1080p, as I don't have an UHD TV yet.

I guess the CFW uses different version of the HiMedia Video Player (maybe the 1.2.53 version as the OFW has the 1.2.57 version for sure). Maybe pcristi can reassure these...

Edit:
So I have tested with OFW 2.1.7 and with this S&M test video (seen on the bottom part of the page) there are no Banding issues with 1080p /YCbCr 444/ 10bit on 23.976Hz. But according to the test description (if we take it seriously), it fails on the Clipping and Scaring tests (the little square boxes inside all the color rectangles are not visible). Tho' I don't know how much this affects the overall video playback PQ in practice... I have also tried it on all colorspace/bitdepth combination available in the Advanced menu, but none were better concerning the Clipping and Scaring test. Wonder how could the CFW perform regarding.
