I am hoping someone can help me...I just bought a new Demension 2400 w/flat screen two months ago.  Yesterday I went on my computer like I normally do after work and the color was fine (blue). I went in the other room and when I came back the screen had green in it. And I mean everything is a shade of green. My Display properties are the same. Nothing is changed. On the Apperence Tab is says it is default (blue). Nothing is any other color then green. Please help.
