my monitor normally has a blue background, but occassionaly, when I start up, I get a poor pastel lilac colour. I can live with it, but is there a fault or is this common?
Hmm, sounds like a fault - my old CRT monitor had similar colour issues due to a loose connection in the power cable. Give it a wiggle (carefully) and see if the colour changes.
thanks for the answers. I've since been told to simply switch the monitor off and back on. This worked fine. I believe its called "degassing" or something!
