I recently purchased a 4k TV and am using a NVidia 1030 fanless GPU. 
Xorg automatically went into 4k mode when I connected the new TV via 
HDMI. My version of mythtv is not the latest (v30.0-58-g4761e7a6d4). I 
am still using VDPAU decoding. CPU is i3-2100T.

That said, I have audio sync. issues for a few seconds, periodically. 
Sometimes the GUI is laggy (MythCenter wide).

My purchase last year was the HDHR-4k model so I am hoping to be able to 
play 4k content. I am pondering moving to a NUC10 and an external hard 
drive enclosure for recordings.
