The display seems to vibrate and have some kind of interference causing the the script and pictures on screen to appear to be vibrating. when changed to a regular monitor this is not going on so I think I ruled out interference from an external source. I also tried to connect the Acer into different power outlets to see if this would alleviate the "interference" with no success. I have only had this monitor for about 2 years..

Re: 22" Acer flat screen monitor
this sounds like an electrical fault or failing component, within the Monitor.
Check the cabling, to ensure it,s not damaged-broken-kinked et,c. by carefully moving the cable gently side to side and up and down.
If it puts itself right for a second or two. you can assume its a broken internal wire, within the lead.
Or a dry soldered joint-Connection.

you have to make sure that the picture you want to use as a background has similar resolution to that you are using in your actual display. for example if you are using 800x600 resolution you should have a picture close to that so it doesnt look distorted.
Ok if you prese the menu button on the monitor does the monitors setting menu appear on screen
If it displays adjust the contrast and brightness until a picture appears
If that does not work place a fringe magnet on one of the corners of the monitor if there is now green tinge around it than there is no electrons being fired at the screen and you have missed something so test every component
Flickering on the screen can be caused by defective hardware in the computer or by improperly installed software, but it can also be caused by interference from external devices. The following examples describe situations in which your screen could start flickering:
Screen starts flickering because of interference caused by devices which generate magnetic fields, for instance:
a TV set
a laser printer
hidden power lines
Apart from interference, an incorrect setting in your system CMOS setup can also cause flickering. On some systems it is possible to distinguish between interlaced and non-interlaced monitors. The setup of your system should always be colour non-interlaced.
Proximity to the monitor of fans, air-conditioning units or other devices with rotating motors.
The number of devices using power from the same electrical line. Are you overloading the plug?
Monitor placed on an unstable surface.
Improper video drivers, this is a software problem, see section B
An improperly configured or a defective video card.
hi, when all connected press and hold the FN key on the bottom left of the keypad while pressing one of the function keys F1 to F12(the one with picture of a screen or monitor). You may need to press it more than once but if will eventually switch the display over to the tv
It's possible your video card or monitor is going bad. Which type of monitor do you have? If it's a CRT then my guess is....monitor.
Check all your cables and connections first.
If possible hook up a known working monitor to rule out memory or video card problems.Monitors have a refresh rate but I don't recommend doing this without supervision or complete knowledge. Check to make sure you don't have any interference close to your monitor. Interference would/could be: magnets/speakers/radio's/televisions/microwaves (not sure about micros. If your have a LCD monitor I'm not sure all these suggestions apply.
