EDID

Extracts extended display identification data information using the RandR extension. Useful in identifying what monitor is connected to your system.

Requirements

You need a compiler and the RandR extensions enabled, version 1.3 of the RandR extension is required.

To find out if RandR is enabled, simply call xrandr (from x11-xserver-utils in Debian) or grep for RANDR in your X.Org server log (usually somewhere in /var/log/Xorg.0.log).

If RandR is not yet enabled in xorg, you can enable it by adding:

Section "ServerFlags"
    Option "RandR" "on"
EndSection

Compiling

Simply call make

Example

I have a Dell monitor connected to my MacBook Pro:
