Ok, heres the deal. I got a ViewSonic 17PS (17" .25mm). The problem is the monitors screen will get bigger and smaller every now and then, its almost like if someone was to mess with the horizontal and vertical adjustment at the same time. It will flash every now and then, almost like adjusting the contrast really fast from semi dark to light. Anyone have any idea what my problem might be? This monitor is rather old, made in 1995. But maybe this is something that is repariable? I dunno. TIA
