AMD Drivers & HDCP

Reinstalled Win 8.1 this weekend and have had trouble with setting things up. Getting display driver errors and other similar problems when I was trying to initially supply both monitors from my nano via hdmi & DP (WMC, Amazon, Netflix).

Swapping to the DP monitor allowed somethings to go by, but to get WMC running I had to enable the igpu and everything then works fine on that monitor.

Some issue with the last couple amd drivers I hadn't heard about?
 
You recall the exact error message?

Smells like DRM at work, and that means you can only use WHQL drivers.
I know a few people that have run into this, all because they used non-WHQL drivers.

Note: Windows 8 and Windows RT video cards require a Microsoft WHQL-certified video driver for your hardware to playback content without restrictions. At this time many USB video cards do not meet this requirement. Please contact your video card manufacturer and search for and install the latest Microsoft WHQL-certified video driver for your hardware.

It was either display driver error unable to play protected content or HDCP error. I know you can't use beta drivers, but tried looking and can't figure out how to guarantee a certain driver is whql signed.

Tried plugging the Nano into one monitor (just one with HDMI) and see if it says HDCP is supported?

Have similar problems but with NVIDIA cards, no problem with AMD cards.
 
Did try just one monitor with both input methods. Had the latest beta drivers than went back to the latest official. Had a 290x until a couple months ago and didn't have the issue then, albeit with a couple driver revs since then.

Is this AMD specific (or Windows 8/RT specific)? I'm using a non-WHQL hotfix driver from Nvidia (368.51) on Windows 10 and HDCP works correctly when watching something on Amazon with Chrome.
