Hi,
I cannot use 3840x2160@30hz with my Intel NUC D34010WYKH2.
The NUC is connected via DP -> HDMI cable. I am running Ubuntu 14.04 LTS where all resolutions beyond FHD are not listed. Using xrandr I can see support for UHD. All modes up to 25hz are working fine. 30hz fails with xrandr: Configure crtc 0 failed. (60hz too - but I am not sure if it is supported with that NUC.) I already bought another cable where the manufacturer guarantees for 4k support @ 60hz.
Any suggestions?
