Shadows on my monitor
Where anything appears on the screen there is a shadow - running the whole width of the screen. On my desktop which is basically blue, there are wider brighter shadows across the screen.
Text is a lighter shade of black. On the status bar text has a faint bright highlight on each letter. Icons are all dull and the sharpness is missing on everything.
The monitor is a ViewSonic TFT and not very old.
Anyone any ideas please.
