Re: wavy or distorted monitor

Wavy or distorted issues only arise if electronics or anything that has magnets in it is near it or on the CRT ( the really huge monitors) so try moving it elsewhere ( In this case you can hire someone with the "magic wand " to zapp the colours back)(general tv repairer.If its an LCD (flat and small screen) it may be dying as the transistors are wearing out ( They usually last for 4 yrs) The only thing you can do is replace the circuit board or the panel . If you have another pc or laptop try to connect it to the monitor and if the pictures are perfect ,its your graphics card .

The best solution to this is to move the screen to another place without electronics or to connect it to a laptop or pc to see if its ok. If the symptoms persist i recommend you to buy another perferably dell screens 19" Lcd as they are cheap and provide good quality.

Sorry for the huge legnth of this Hope it helps :)

Screen colour distorted

Your monitor needs to be replaced more than likely.

Try using another monitor to isolate the problem. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok, then your original monitor is bad. If the Borrowed monitor shows the distorted colors, then your video card inside the computer is bad.

Gateway VX 920 Diamatron monitor has wavy lines at bottom

Since this is a CRT (Cathode Ray Tube) It is no longer cost effective to repair them. Your Tube Driver circuit (internal non-serviceable parts) is starting to fail.

I thought the screen was broken but its not , my laptop went ranbow coloured from one side and i dont know what to do?

try updating the video driver on and selecting drivers and downloads input your service tag it will bring up all your drivers . under video category look for your video driver. If you don't know which is your video driver go to device manager and under display adapter it will display it. if the rainbow distortion still is displayed try a diffrent monitor .If it show the same thing in another monitor then its your systems on-board video . If your system has a video card then replace video card.

Is this a MS-7184 problem? My son's computer has a wavy screen, so I replaced the CRT monitor with a new flat screen. Still wavy. Next, I replaced the onboard video card with a PCI card and nothing shows...

you need to install drivers with the new video card but first you must uninstall the old one-definately a driver issue(assuming all cables are good,etc)

Desktop frozen with the monitor showing disorted, green blocks

Try rebooting your computer with a disc or discs that came with it. That disc or discs should reinstall windows. If this does not work try getting linux or dos on a cd an try betting from the cd instead of the HDD. If this does not work either then it must your graphics card or HDD. I am leaning more towards graphics card because ussually your computer will give you a blue screen if your hard drive fails.

Monitor screen shrinks!

The problem is due to under voltage.You may have an unstable power or your computer auto voltage regulator (AVR) is not doing its part..If not then you have a busted capacitor..resolder all capacitors and replace ruptured capacitors with same value and ratings..

Computer monitor becomes distorted after boot up.


Download and install the correct driver for the monito as well as the deiver for your video card, if the video is onboard, you may need the motherboard and AGP driver as well.
You will probably need to boot in Safemode to do this.
Good Luck.

Computer loading/splash screen pixilated and distorted

if you can, hook the computer up to a different monitor and see if it does the same thing. It sounds like it is an issue with your monitor initalizing but the reboot can complicate things. Also if you have a cd that came with the computer you might want to put it in and see if you can re-install your video drivers. One last thing is to check and see if the reboot might have changed some of the settings on the monitor itself. See if you can reset to factory default or an auto adjust. It depends on the kind of monitor as to wich option you can do

Monitor distortion

Hey edwardaaron,

If you are encountering any kind of visible distortion on your computer monitor, there are a couple of things that I would suggest.

First, if you have a cathode ray tube (CRT) monitor, you may want to try manually degaussing the monitor. Whenever a CRT monitor is in use, it slowly builds up a magnetic charge that can interfere with its operation. Degaussing then, is the process by which CRT devices rid themselves of this excess magnetic charge. This is normally done whenever a monitor is first turned on, but many monitors will also have either a button on the front control panel you can press or an option in the main menu to perform a manual degauss.

In many cases, the degauss option will be marked with a horseshoe or magnet-shaped picture. Once you've selected this function, you may notice a metallic-sounding "twang" noise, followed by one or two "clicking" noises as the image on the screen is reset. Keep in mind that images on the screen may appear to vibrate and color may distort for a few seconds after you do so, but this is a normal part of the degaussing process. The screen should return to normal after a few seconds.

Second, interference can also be caused by placing your computer speakers too close to the monitor. Many speakers will produce a magnetic field of their own, which only adds to the magnetic field generated by your monitor. In this case, repositioning your computer speakers should help minimize the problem.

If degaussing fails (or you don't have a CRT monitor), you may wish to then test the cable connections to your computer. In some instances, simply replacing your monitor cable will resolve these types of problems.

You may also be encountering a problem where your monitor is simply set on the incorrect refresh rate. If the refresh rate is not correctly set, a monitor may display a "wavy" image or appear as if lines are periodically scrolling across the screen. Without knowing the exact make and model of your monitor however, I would not be able to provide any suggestions on how to change this setting - you would need to contact the manufacturer or refer to your owner's manual for specific instructions.

The worst case scenario would be if you are encountering an actual hardware failure. Both the video card and monitor can cause images to be distorted if they are not functioning properly, and even power supplies have been known to cause other components to sporadically malfunction. If you are unsure how to perform a hardware diagnostic, I would strongly suggest speaking with your local computer repair technician or a Geek Squad® agent at your local Best Buy™ store for further assistance.

Hope this helps you out.
