I have an older(I'm not sure how old) 17" monitor which I bought used a few months ago. Last night when I went to bed everything was fine but this morning when I turned my computer on it was all screwy. The top 2 corners are green and the bottom 2 corners are pink. I'm not sure if this is my monitor though because I took a print screen of it and when i viewed the image in the center of my screen (which is still normal), the colour is OK. I am running Windows XP Pro.
