I recently installed a Twin Turbo 128 M8 video card in a PCI slot in my Mac G4 to drive a second monitor (17 inch). The card seems to work okay because the monitor comes on and I can move images to its desktop, however, I don't know how to change the resolution.
When I installed the software for the Twin Turbo and tried to access it through the control panel (the way you would normally change the resolution with the card), I got a message that said a Twin Turbo card was not detected. I assume it located the main video card that drives my primary monitor.
My question is, how do I change the resolution on the secondary monitor that's using the Twin Turbo video card?
