 As I'm following along with your progress - and thank  you for taking up this challenge - can you list what set-up you are using to test?

Sure. It's nothing special, as I target a Full HD TV. Custom built HTPC with Intel DH77EB Mainboard (because of onboard CIR header), Core i5-3550S CPU and 8GB RAM. 

 Sorry if I'm not following fully here.

The i5-3550S is 7th gen? It can be hard to figure all these numbers and working names out at times.

The MB has HDMI 1.4 or 2.0?

4K playback with full HDR?

Lossless audio passthrough with working Dolby Atmos and dts:X?

Thanks again for working this through!
