- Occasionally black screen every 30-40 secs with 4K HEVC/10 Bit (Color space settings are set to 4:4:4)
If i set the color space setting to 4:2:2 there is no blank screen, however there is no 10Bit output too.

- No 4:2:0 output setting, why? Most of the sources are recorded in 4:2:0. Is this output mode is not supported by the Hardware, or is the internal processing done in 4:2:2 or 4:4:4.
What i can say is that internal hw processing is not done in RGB like it seems in Nvidia's Shield TV. The goal is to do less modifications on the source as possible.

If you have deep color on, you will get black screen (AV dropouts) at 2160p. To prevent this you can either select 4:2:2 or turn deep color off at 2160p.

4:2:2 output can only be 12-bit as per HDMI specs. If you set it to 10-bit, on reboot there will be no video output.

4:2:0 is allowed only for 50/59.94/60Hz at 2160p as per HDMI 2.0 specs. If you select 3840x2160/4096x2160 50/60Hz, you will see 4:2:0 as an option.
