=== Using video modes not available according to EDID === | |||
Normally the monitor tells the computer what its supported combinations of resolution and refresh rates (video modes) are. This system is called EDID. | |||
If for some reason you want to use a mode that is not in the list of EDID modes, you have to add it yourself. This is typically the case if you use an analog connections to the monitor. | |||
Before adding a mode you have to allow it in /etc/X11/xorg.conf (this file may not exist yet), the crux is in the line containing ''AllowNonEdidModes'': | |||
