Late Christmas present

So while messing around with the VGA cable wiring, the O2 I ordered arrived at my doorstep :-)

So after unpacking it, I hooked it up.  Yes! It boots and displays on my DELL..... but wait a minute, the color seems to bit greenish and the image is not centered, #@&§ again display problems.

I'm getting a bit fed up with this.  In a few days I'll fetch an old CRT screen from my parents and see if I can get a different result using that one.

If anybody can help me out, don't hesitate :-)
