In Reply to: Laptop -> Arcade Monitor; refuses to toggle display?? posted by kris on 27, 2000 at 1:07 AM:
Rage Mobility is a dual monitor chipset, your LCD and VGA port are basically two different video cards. Not sure on how to get it working with an arcade monitor.
: 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
