Ive just switched my pc on and at first attempt couldnt get my monitor to come on, so I checked connection at both ends and finally got it to come alive.
Problem is , its a wierd colour

everything is brown . the pick I have on my desktop is black and whithe but!!! brown parts to it . if that makes sense .
Ive tried all I can think of . Its a TFT flat screen monitor and I havent done anything to it that may warrant it going funny so im really puzzled.
any suggestions please.

even my accyweb is brown
