Hi, I don't quite know what I'm asking, I'm just fishing for responses :)
I got a Matrox DualHead2Go which splits a vga signal across multiple
monitors. Atm. I have it driving two screen with a duplicated image but
if you supply it one of these modes :
edid 2048x76...@60hz
clock=113.75
shb=2136 ehb=2200 ht=2352
vrs=771 vre=786 vt=806

edid 2048x76...@75hz

edid 2048x76...@85hz
clock=165.39
shb=2160 ehb=2232 ht=2408
vrs=769 vre=781 vt=808
hsync=- vsync=-
It will become two distinct screens, half on each monitor.
You can see form my Vesa mode dump that we don't have that in the list.
My nvidia card (8600 GT dual SLI) is aslo unrecognised by the vganvida.c
