Can somebody help out there. Not getting any help?? I have a scanport 822a monitor and a Dell 4500. I need to correct this issue so it can be used for school for kids. The monitor will go off center. It worked for a week now it happened again.I have tried drivers for the dell chipset and video. What the heck am I missing. I can correct the most complicated issues but not this simple one.Is there another driver. What gives??
