I'm using a Massdrop Vast monitor hooked in over Display Port 1.2 First I had HDCP errors trying to watch movies, and now I'm getting Connectivity issues are limiting playback error. I ordered a new cable in case the cord that came with my monitor is bad somehow. ANy insights are helpful. Also for those of us that perfer to watch movies on our PC you should allow UHD as I'm running a 1440p monitor and would like to see the better quality.
