Help with 4" LCD

So I bought this LCD as seen in this thread here:

And i've installed it as he had in his pics. Problem is it's appearing as Black and White.

Now, the screen isn't faulty, I've been in my BIOS and that appears as Blue and Red as it should do, and the Windows logo on boot is in colour, but when in Windows the screen is (or appears) black and white.

I've tried everything, changing the output to PAL / NTSC (every version), messed with brightness, contrast, hue, saturation, etc, etc, etc to no avail. I tried the TV out on my laptop and that was the same, I even plugged my camcorder into it (the screen has an S-Video connection) and that was black and white.

To me this sounds like a PAL / NTSC problem but I don't see how it can be, if none of the settings make a difference.

Any ideas?

If it makes any difference the computer it's installed in is running a 7800GTX.

Fixed it, just used the AV box from my 59000Ultra instead of the 7800GTX and it solved it.

where do you normally buy those 4" screens from? they look awesome
