I just got new vga cables and a new kvm switch and now have some visual problems. I thought i bought high quality cables but I am leaning to that being the problem since the switch i am using has been recomended by other users on here. The problem I am seeing is sort of flicker or streaking of dark colors across light. It is mostly noticable on whits screens when a dark object appears. It looks like black flickering streaks reach from the object across the light colored background to the edge of thew screen. It is very faint but noticable and annoying. Any suggestion?
