Greetings.
My laptop has an ATI Rage Mobility Pro M-1 gfx card in
it and it should probably work with my 21" arcade monitor. However it refuses to toggle between the LCD screen and the VGA cable i made going to the arcade monitor. I gather this is because the way it detects a monitor is plugged in is via an imedance across two of the pins. But which pins and what impedance? Anyone know??? Anyone know of a way to force the ati to use the external VGA adaptor?
Thanks
