Gaming Screens

[Gohobojoe]

I've decided to connect my monitor to my laptop. Except when I use that monitor, the color shifts a bit. Take for example, GBAtemps's blue background. When I put this window on that one, the color shifts and becomes a dark blue-green. And white doesn't look as white as the white on my laptop screen.
Why is this happening?

When I use the monitor normally with my PC, all the colors come out normally. Oh, and I'm using an HDMI cable to connect the laptop and the monitor.

Most likely a loose connection. Make sure the cable is fully attached, and try using another cable to see if the same thing happens.
