Hi, Even if it is refreshing, shouldn't be that noticeable. One possible reason is not enough memory in your video card for which you can try compensate by increasing the Graphics Aperture Size in your CMOS/BIOS setup. Normally it should be twice of your on-board/add-on video card memory. Another possibility is your LCD monitor is showing signs of pending problem which could either be the CCFLamp, the inverter that powers it or the video interface. Some models of Viewsonic are known to have inverter failures. Specifically, the capacitors are overheating and would need replacement. In some instances, it is the lamp that goes or still others are simply cold solder joints. Hope this be of some help/idea. Post back how things are or should you need additional information. Good luck and kind regards.
