Hi
With the new alpha builds having the option to change colour space, I was woundering what this is and or means?
Do I need to find out what my tv supports and set it to one of these or is there more to it? Which is best etc. 
Thanks.

For normal HD TV use 444,8bit. If you have a UHD TV, use 444,10bit

brilliant, thanks bud. Much simpler than I thought.

I use automatic color space - Why should I change it manual

Can you explain what you mean by "automatic", and how you selected that?

the newer builds, you need to select manually.

I do nothing - colour space changes automatic to 444,10Bit playing video

Doesn't work on my boxes, I'do some tests;)

I didn´t check every video file, but playback looks OK.
Some files checked the colour space - all OK - SDR/HDR is recognized by the TV
I´m only using my 4k TVs(connected vie AVR) to play video or music files from NAS - no live TV, IPTV, DVB-S2 tuner etc.

Nope, no auto-switching on bits on my boxes. It sticks to what's in "/sys/class/amhdmitx/amhdmitx0/attr".
But it do switch from 444, 422 and 420 depending on values in disp_cap. So the trick questing here is, Can one also define Bits in disp_cap?
Anyone??

422 8/10/12 aka. 24/30/36 bit are have been present for a long time, you can choose these colorspaces on all DVD players, Blu-ray players from last 10 years and doesn't switch automatically to these colorspaces. UHD players and of course these boxes too can switch to UHD 420 10 bit, but 422 8/10 bit or 444 8/10 bit works only manually. So, if you choose 444 10 bit is very good for gradients but if you watch a UHD 10 bit movie the player will be switch to 420 10 bit all other movies will be played on previously setup, ex. 444 10 bit.

Either I´m stupid or lucky.
Checked a few min ago.
Recorded TV 720p(SDR) - OK
Recorded TV 1080p(SDR) - OK
4k 10Bit HDR - OK
My combination box-AVR-TV is working well - TV switching from SDR to HDR and back to SDR, also 420/422/444 depending on video file
Maybe some combinations are not working (my TV is from 2017, my AVR from 2016)

Dose your AVR/TV actually say YcbCr 444:30bit (3*10bit) or is it just the HD/UHD(HDR) that changes?

422 and 444 are fix colorspaces which is selected in colorspace settings, The TV switches between 422/444 (depends on the setting) and 420, no switch automatically between 422 and 444.

Yes - AVR reports YcbCr 444 or 422
TV reports SDR/HDR

And 8/10/12 bits also is also reported?
-
Bits are also reportet by AVR - but I never saw 12 bits

One mustn't mix bits & HDR. I you set your GUI to 720p and disable rate change, than play a 4k HDR movie your TV will report 720p HDR. But this has nothing to to with the amount of bit used for colors.
