I have an old NEC monitor and when I plug in the screen to the 7500 the screen's image is all distorted. I think it is because the monitor doesn't support the 7500's resolution. It's to distorted for me to see where the mouse is going so it would be impossible to change the resolution. Is there a key combination that will change the resolution or at least open the monitors control panel. The 7500 is running system 8. I plugged in a Cetris 650 to the screen and it worked fine. The NEC monitor is VGA so I am using a VGA to Apple converter. Any help would be great. I'll try booting with extentions off, maybe that will do something? Also the Cetris 650 has its own graphics card teh 7500 is just using the one that is on the motherboard. Thanks in advance
