Hi Guys, Well after all my troubles with the ASRock MB, I'm now running a Gigabyte Z68P-DS3 which only has a HDMI output. So I managed to get hold of a HDMI to DVI cable, but I can only get 1024x768 :( $ xrandr -q Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.0* 800x600 60.3 56.2 848x480 60.0 640x480 59.9 HDMI1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 474mm x 296mm 1680x1050 59.9 + 60.0 1280x1024 75.0 60.0 1440x900 59.9 1280x960 60.0 1152x864 75.0 1024x768 75.1 60.0* 832x624 74.6 800x600 75.0 60.3 56.2 640x480 75.0 60.0 720x400 70.1 DP1 disconnected (normal left inverted right x axis y axis) So it knows the HDMI output supports 1680x1050, but it's picking the VGA instead Any idea how to tell it to pick HDMI?
