I have a slight problem with a VGA monitor which is connected through a Belkin KVM to two different computers. You should be able to see from the image what I am talking about... It is a photo, not a snapshot, so just ignore the wavy pattern due to the camera, the problem is the white vertical shadows:
Every black line on light background has this weird shadow which is very annoying. As a note I should say that this does not happen when the monitor is connected straight to the computer (so the problem seems to be signal degradation in the KVM).
Not being able to remove the KVM (I need switching every now and then) I was wondering if you know some settings or calibration that could compensate the problem. What I am doing now is imply to raise the contrast so that the artifacts washes out but this is not an ideal solution.
