Hardware :: Colour Profiles For External Screen (Dell E178WFP)

I screwed up. Or I'm too poor to do things right. I bought a Dell E178WFP, 17" 1440 x 900 @ 60 Hz, 32-bit color external flatscreen. And I live in Egypt and can't take it back. I should have bought an Apple cinema display, but it would have been five or six times the price. The problem is its colour profile. I set it the same as my powerbook, to LCD Color, but it still looks like a PC screen, and I hate that. One of the reasons I love mac is the subtlety of the colour of the screen; it is calm and has depth, unlike PCs which always look garish and brash to my eye.

Is there anything I can do? I explored the color settings, but so far can find no way to actually set the external screen in a way that it renders like the main screen of the powerbook. Ideally, I'd have them both near enough the same. Theoretically, this should be possible, no? Given that I'm running the external off my mac, and that it's a simple LCD that can render millions of colours...........
