cotmm68030, I think you are right about the resolution. I didn't even realize, but once we rebooted the PC, QuikRes got turned off, thus the setting is probably not set at 320x200. I had an idea. Perhaps we should add QuikRes to the StartUp items so that it automatically launches. Also, we can set the default res on it to 320x200. So everytime we start the PC, it will automatically start QuikRes in 320x200 mode. Does this sound like a good idea? Also, one thing we didn't try was simply setting QuickRes, then simply plug in the arcade monitor without rebooting the PC. One more thing. We don't have another PC to use UltraVNC on. We only have Mac's... Is there a Mac version that we can use? Perhaps something like Microsoft Remote Desktop Connection. I know I can connect to my work from home on my Mac to my PC at work using RDC. Is UltraVNC the same thing and is it available for Mac?
