It should provide a 1920x1200 display + audio via the monitor. When it does so, xrandr reports: xrandr -q Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 8192 x 8192 DIN disconnected (normal left inverted right x axis y axis) VGA-0 disconnected (normal left inverted right x axis y axis) DVI-0 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 60.0*+ 1920x1080 60.0 1600x1200 60.0 1680x1050 60.0 1600x1024 60.2 1400x1050 70.0 60.0 60.0 1280x1024 75.0 60.0 1440x900 75.0 59.9 1280x960 60.0 1360x765 59.8 1360x768 60.0 59.8 1280x800 74.9 59.8 1152x864 75.0 75.0 70.0 60.0 1280x768 74.9 59.9 1280x720 60.0 1024x768 75.1 75.0 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 720x576 50.0 848x480 60.0 720x480 59.9 640x480 75.0 72.8 72.8 72.8 75.0 60.0 59.9 59.9 720x400 70.1 4) The display generally starts fine, but intermittently, after apparently random times and with random programs running, the display turns off and the monitor reports no HDMI output. Logging in from another machine, everything appears to be normal and xrandr reports the same as above. However, there is no HDMI output to the monitor. This can be fixed by xrandr, using first: xrandr -d :0 --output DVI-0 --mode 1024x768 which makes the display visible again, in the lower resolution, then xrandr -d :0 --output DVI-0 --mode 1920x1200 which restores the original display. Things then function normally until the next random HDMI output failure.
