I have a Dell U2312HM monitor connected to a Dell Latitude E7440 laptop via a HDMI-DVI cable. I'm running it on Ubuntu 14.04. I had an issue with the monitor blinking from time to time (reported here), so I changed the cable which solved one issue, but created another. Sometimes the display on the monitor is just fine, but more often than not I'm getting this message:
This is the output of
HDMI1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 287mm 1920x1080 60.0*+ 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1
How is this possible? What is different in these two cables that causes such differences?
