Extended Display IDentification is data about the monitor, which the monitor provides to the video card. EDID is the programmatical way to check if a video mode is supported. However, this procedure is rather complex. (See VBE).
Reading EDID
The first step, is, naturally, to actually get the data. This is done through the BIOS - int 0x10, ax=4F15h, bl=01h.
mov ax, 0x4f15
mov bl, 0x01
mov cx, 0
mov dx, 0
int 0x10
;AL = 0x4F if function supported
;AH = status (0 is success, 1 is fail)
;ES:DI contains the EDID
Note that this code will only run in Real Mode or vm8086.
