Salmon Trout -
Thanks for your reply. I have an E Machine flat panel Monitor, which is an LCD. HOWEVER, I have solved my problem!! While checking the user guide I found out that there were 5 buttons on the side of the monitor. These buttons control the color and other operations. Apparently some time I accidentally pressed one of the bottons and changed the tint of the screen. When I read the directions I corrected the problem. I apologize for taking up your time. Consider the problem corrected. Thanks Bob
