Yeah since this post i know now my post was confuse. I don't remember but either all movies even the "most HD" ones are 4:2:0 or 4:2:2.
Actually on a side note for some that are into detailed tech (not important to know) even UHD movies are not real 4K. They are usually 1080p, the 4K is for brightness informations, that kind of things.
Anyway, I was looking again to build a small form factor pc like you guys did (tired of my macbook pro overheating even when using chrome javascript games).
And it look like there is still not a real all round and known answer to the specific question :
Is there a mini itx am4 motherboard that does support HDR? (so hdmi 2.0a minimum), same question for HDR+HLG (so hdmi 2.0b)?
Because on this post some says asrock said it don't, some said asrock said it depend ONLY on the CPU.
Maybe hdmi 2.0 to hdmi 2.0 a or b is just a software update (apprently it's even the case for hdmi 2.1 that is not released yet). Or maybe the MB have to be compatible (software update or not).
I just want to see my options to build a small form factor PC / smart tv / htpc multi use system. And I really want to know beforehand if in the future I buy an HDR TV, if the build will be compatible or not. There is too much good HDR content for me to not considering it before buying. A 150$/200$ MB is not something i want to replace in 1 years or 2 when I'll have an HDR TV/monitor.
