Ok, so I've tried this thing out, and It doesn't work. I've tried hooking it up to two different iBook G4s and also a PC and the display will not power on. I played around with the different refresh rates and still nothing. Both iBooks are running Tiger, and the PC is running XP. Is there something I'm missing here? The led on the converter box lights up so I know its getting power and the power indicator on the display will flash on and off when I select a refresh rate of 75 hz but it won't actually show an image.
