HDR10 YCbCr444 10 bit at 2160p 60

[magicoolje]

Hello,
Does Himedia Q5 Pro support HDR10 YCbCr444 10 bit  at 2160p 60?
I tried this on my LG 65 UH850V which support HDR10 and DV and I only get HDR YCbCr444 at 24 HZ. I can't switch to YCbCr444 10 bit at 60 hz.
Does anyone experience this problem?

there NOT any device support YCbCr444 10 bit at 60hz , HDMI 2.0 support max  YCbCr444 10 bit at 30hz.

try YCbCr422 10 bit at 60hzy.

it's equal because there are NOT any material at  422 , UHD blueray and all 4k material are  420... maybe in future ....SAT-TV Astra do some test at 422.

I think the YCbCr422 setting in Q10 Pro outputs 8bit.
Anyway there's no option to select 10bit for 422?

YCbCr422 10bit at 60Hz is allow by in HDMI standard.
YCbCr422 12bit not official support by HiMedia, but can try to get with the PATCH or AFR helper when video is play.

Enjoy HiMedia players.

Q10 Pro and Q5 Pro known to have problems to "auto" switch to the most accurate colorspace and bitdepth when switching down from 60Hz, when playing a video, to fe. 23.976Hz. To eliminate this, you must keep your GUI refresh rate setting at 30Hz, set the colorspace and bitdepth to 444 / 10bit and than, when starting a video, with presumably lover fps (and so refresh rate)  the colorspace and bitdepth stays at the same setting as it was at 30Hz, which are the most "optimal" in the aspect of picture quality.
