Hello, I currently use my PC's monitor as my PlayStation 2 display, using a KVM switch and VGA adapter. If I buy a 17" iMac, could I use its monitor in a similar fashion? I have seen USB TV tuners with appropiate video input for the iMac, but these have a rather low resolution, 320x240 or so. Are there any for FireWire? Will the different aspect ratio of the iMac monitor cause any problems?
