I have a iiYAMA "Vision Master 17" monitor. This is a problem I've been chasing for some time now. The best way I can describe the effect is that periodicaly object will appear on the screen with their assiciated colouring displaced or smearing to the right hand side. A sort of ghosting effect. I've replaced the VGA cable and even tried different graphics cards but the problem still remains. I've witnesed the same effect on a iiYAMA monitor at my place of work. When the fault is present I can temporarily cure it by just wiggling the VGA cable around but it will always re appear. If I push against front of the monitor gently causing it to rock for a second or two the effect varies in intensity. It's almost like some kind of earthing problem. The only way I can permanently fix the problem is to use A VGA to the five BNC connector input. This is all very well but I have two computers and it would be nice to take advantage of both inputs to the monitor. Has anyone else experienced this problem with iiYAMA CRT monitors?
