    External second monitor colour issues.
    I have my white unibody macbook connected to a 1080p (PAL) tv via HDMI cable to a moshi adapter. I've had no problems with it at all until I turned it on this morning and the colours are messed up. There are no red tints only blue and green, even for the "close" and "minimise" icons they are green instead of red and orange/yellow. Also icons that were blue such as the scroll bar on the right hand side of the screen are more purple. I remember having a similar issue when I first connected the second monitor but it was fixed easily by clicking on something that I can't remember. Can anyone help me?

    If it was previously working fine and now the colors (US spelling) are off, I would first suspect the cable or connection. Reconnect or reseat the HDMI cable or the adapter to see if that makes a difference. You might also try wiggling the cable a bit at both ends.
