Desktop Video FAQs

Q: The edges of my display shake or quiver rapidly. What causes this and what can I do about it?

A: You may be getting interference from something in the room. The source is usually electrical. The effect may be constant or intermittent, depending on the source. A large power source or other interference near the monitor usually causes constant shaking. Intermittent effects are caused when other devices are turned on or off. Possible sources of interference:

• Power base with plugs and switches.
• Printer or other peripherals
• Power strips.
• Fluorescent lights.
• Appliances containing motors.
• Wiring inside walls, floors or ceilings
• Electric meter or power panel.
• Metal shelving.

You can try turning off all peripherals near the computer. If the shaking is reduced or gone, begin turning on one device at a time to identify the item causing the problem. If the shaking is still there, then try to move the computer to a different room.
