Monitor picture jitters

It's possible the Monitor has failed, but here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

It is possible that your monitor is on a GFI switch. These switches turn off if they detect a problem that could incur a shock, or if they are getting worn. Check if there is a power outlet in the same room with a red and black switch. If so, push the reset switch, typically the red one.

Your monitor may also be on a switch activated outlet. Is it plugged into the top outlet? See if a wall switch nearby controls the outlet. then try turning on your monitor.

Is the surge protector your monitor is plugged into turned on?

Check the cord on the back of your monitor. It is possible it may be loose. Plug it in all the way.

Some Viewsonic monitors have a power pack that is not inside the monitor case. Check the wiring between it and the wall and between the pack and the monitor for frays.

mrjk65, If monitor still has bright, crisp images displayed on the LCD panel your monitor could be worth saving! Unplug unit from wall outlet and plug it back in! If same problem occurs then most likely problem could be a DC voltage is slightly "out of spec" or a settings panel push switch may have failed. My guess is that when STRANGE out of the BLUE things start to happen for no reason, I would suspect the "switch-mode-power-supply" to be the item at FAULT.

you need to get a better grade cable from the wall outlet to the plugs for the computer and monitor it most likely can not take the load high energy use will cause degrading on the wire and can cause a fire hazard, at your local hardware store they can sell you a better quality extension with a power surge protection unit built in that would be best.

(I'm copying a guest's comment above. What Gateway told him does seem to work - although in my case, the monitor was slow to start when plugged directly into the wall, and it was immediately fixed when I plugged it back into a heavy duty power bar.)

hey, I had the same problem. Gateway told me "Plug the monitor power plug directly into a wall electrical outlet
or a different wall outlet by removing any surge suppressors." I did that and it works. It might be a certain kind of power bar they do not like. It worked for me so try that and see if that helps.
