I would really like some more information because (after reading way too much info) I don't think 4K netflix streaming would be working because it needs HDCP2.2. Intel chip only outputs DisplayPort 1.2 which don't include HDCP2.2. The intel NUC have a HDMI 2.0 output because they used a LSPCON from megachips.
You can see a datasheet here : http://www.megachips.us/products/documen...abrief.pdf
On page 5 you can see that the only way this adapter adds HDCP2.2 protection to the displayport is when it's integrated to the motherboard. If it's external it's just a repeater, like the Parade PS176 chip which is used in the uptab adapter you bought. And being a reapeater, it can't repeat HDCP2.2 if the source DisplayPort don't have it.

Could you make a test with netflix 4K to see if it works?

It's impossible to say what will be needed for HDR with the intel platform, but it seems we at least need hdcp2.2 for 4K.

I'm still searching for an affordable kaby lake motherboard with the LSPCON chip. I don't seem to find any. The only one I found are the asrock fatality series (only some) and the cost is crazy expensive which means that it's nearly cheaper to buy a simple motherboard with an additional GPU nvidia 1050. (Crazy?!?)

I still want to find a motherboard so that in 5 years I can buy a gpu with new video features if needed.

So.., I had to wait to get the new HDMI cables in to be sure that it would not be a cable issue.

Netflix 4K seems to be working when using Edge, in the last Insider Fast build of Windows 10 that is. No HDR output though.
When using the Video and TV app and selecting a HDR Demo file, the video starts with a green image, but after some time, the image pops up, but still no HDR (popup) visible.

I don't know for sure if my setup is enough to get the job done for HDR, there is doubt about that at this moment. Besides HDR all the other video stuff works great and that is satisfying. When looking at the specifications of the Uptap adapter, I thought this would (or could) be the solution for my setup, but I don't know. Video (and HD-audio) is working just fine, but for the finishing touch (HDR), still in the dark at this moment. Maybe it's still a bit to soon?

Since you have a desktop Kaby Lake are you going to look into this?

I saw that news today, but I can't place one of those drives in my current case, it's much to tiny
I scratch my head when I look at the minimal CPU Kaby Lake specification for these UHD drives. Core i5, really?

On the positive side, it's cumming, slowly but cumming.
