Shadowing on lcd screen -help?

[BillyF]

I have a 21" Dell lcd. I think it used to show font and images clearly. (my personal computer for email, browsing, etc)

I just noticed yesterday that there is a significant shadowing with the font and images. When I type A, I see a typed A, and also see a shadowed A right next to it.. it's like seeing double blurry vision. Images also show a shadow copy.

Using ClearType doesn't change the shadows.

I set the monitor to 800x600 and the native 1200x800 and the shadowing is the same.

I do have a long video cord for it, 30', however the video image was clear for many months using the same cord.

The monitor is analog. Graphics is integrated Intel Extreme Graphics.

My eyes would be so appreciative of any help or ideas!
thank you..

try re-routing your video cable away from any Power cables, also try looping the cable in a figure 8 a couple times, you should really get rid of this big cable, shadowing is a common issue in longer cables, it's caused by video signal bleed between wires.

did you install the monitor driver and select the color profile ? try calibrating your monitor (there should be an option in most monitor softwares)
