TOPIC

    I have a Multiple Scan 15 Display and the top of the video image is skewed. As the is rotated around in a circle, the problem gets worse or better. This problem occurs even when the monitor is not sitting on the computer or close to the computer.


DISCUSSION

    The symptoms described appear to be a classic case of external interference. Your guess that it is most likely due to the earth's magnetic field is most likely correct. In any event, it seems as though something external to the display is causing the problem. Try the following:

    1. Move the display/CPU to a different building and see if the problem persists. My guess is that it will then work satisfactorily --indicating a problem in the environment you have it now.

    2. If there are metal objects in the area (ie. large metal cabinets, desks, or other fixtures), use a hand held degaussing coil to demagnetize these items. They can be the source of the problem.

    Finally, if the problem is the earth's magnetic field there is not much you can do to correct the situation unless you move the monitor elsewhere, or swivel it on its axis to a point that minimizes the distortion. All monitors can adversely be affected by stray magnetic fields.
