I was recently able to pick up one of the smaller Apple color monitors (I can't recall which one exactly, I think it's a 13", and in any case, it has brightness and contrast dials and the power button on the front, and it is mounted on a swivel/tilt base...maybe that helps!) and an LCIII for $15, so I thought I might be able to use the monitor with a PC and bought the setup. Since I don't have a PC (yet) I thought I'd test it with my wife's iMac DV. I plugged it in and got the familiar "scrolling lines" effect (you'll know what I'm talking about if you've seen it before, it's kind of like a TV with the vertical and horizontal hold misadjusted). I tried changing the resolution, etc., but nothing seemed to help.

Of course, before all this, I was looking through the Apple Spec Database and it said that this monitor wouldn't work as a VGA monitor, but I figured stranger things have happened, so I tried it anyway.

To make a long story short, is there any kind of easy and cheap way to make this monitor work with a PC? I'm thinking along the lines of a small cable adapter or easy hardware hack, not some $100 VGA to Mac converter box.

TIA,
Matthew

The thing is that that monitor is fixed-frequency; it syncs to 67Hz ONLY, not to the 60Hz most PCs default to (the iMac DV's 640x480 is 117Hz). You need a plug adapter, which you must already have since the iMac DV uses a PC-style connector. A 67Hz monitor can sort of display a 60Hz signal (well enough for you to find the Windows Control Panel and change it to 67Hz), so just set the PC to 640x480 at 67Hz andf it should work.
