Quote I have question about PC configuration for UHD BD playback.

This configuration HTPC suitable for playing UHD BD with HDR:

CPU: Intel Pentium G4600 (G4600T)

MB: ASRock Fatal1ty Z270 Gaming-ITX/ac

I'm using a older version of that MB ASRock Fatal1ty Z170 Gaming-ITX/ac and it is working (except for HD Audio bitstream, see my other thread). Cannot say for sure about the processor as I'm using a 7700K. But according to CyberLink requirements it should work. BUT if you are looking to use the Pioneer UHD Drive it has it's own requirements:

And according to those you need i5/i7...

Thanks. I know this specification.

I think the main requirements are the Intel SGX and HD Graphics 630.

For example in this specification there is a requirement: Intel 200-series motherboard. But you have previous version of motherboard and it works i3 7100T + AsRock Z270 ITX + Pioneer BDR-211UBK

Only 4-core CPUs will work, I guess. Pioneer says i7 or i5 only, not i3 or anything below. I am going to buy i5 7500 this week.

Your motherboard should be OK, see more here: http://forum.blu-ray.com/showthread.php?t=287599 .
