Make sure to change above's HDMI1 to whatever your output device is - you see in Xorg.0.log. It might be DP1 for newer HDMI 2.0 device or HDMI2 for others. Also see that the 4k@50 and 4k@60 modes are commented out - as HDMI 1.4 does not support them. If you need them (HDMI 2.0) just comment them in (bottom) and also in the Modes line above, by removing the #

Hi fritsch

I created the xorg.conf file with the information you supplied I just changed my PreferredMode to 1920x1080@60p and changed the Identifier to HDMI2 (even though my intel nuc box is connected to HDMI1... ) and all is ok on my box... many thanks for your help, hope it also works for alex.ba .
