Problems with Computer Monitor Image

When having problems with computer monitor image there are usually a few simple configuration changes that will help to fix the issue.

If the image has a blue or green tint it may need degaussing, to do this you'll need to enter the monitors control panel from the buttons on the front, and then find the degauss option. Don't be alarmed if you computer makes a loud buzz when it does this, its perfectly normal.

Is the image dull or dark?

From the monitors menu adjust the brightness and contrast as required. If the brightness or contrast is already at the 100% this usually means that the tube (if it's a CRT monitor) has developed a problem, once again the monitor will need replacing.

Does the image flicker every so often?

Check the power cable is securely fitted to the monitor.

Make sure the wall socket is not faulty (if it's loose or any of the internal cables are loose, this can be lethal, so make sure any electricity is turned off before examining this)

Otherwise it could be an issue either with a loose connector within the monitor or a faulty power supply, this usually means it's on it last legs.

Is the monitor's resolution set correctly? If not this can lead to everything being too large, too small or simply out or proportion.

This needs to be changed from your operating system,

Start Menu > Control Panel > Display > Settings tab

Now change the Screen Resolution to suit your taste.

Change the Color quality to give better image viewing quality.

The final option is the refresh rate selected the Advanced button > Monitor tab

Screen refresh rate: Windows will generally find compatible refresh rates for your monitor, but as a rule of thumb the higher you can go the better (but best to check with your monitor manufacturers for this figure) if your refresh rate is too low you may notice your monitor flickering slightly, this can lead to headaches and eye strain.

If the monitor appears to have any tiny specks in the screen display which look out of place compared to the rest of the screen this is called a dead pixel, nothing can be done about this, it's just a question of whether you can live with this, if not it's time to replace the monitor.

Does the monitor have any unusual horizontal or vertical lines? And no matter what is displayed the lines are always there.

Once again this is generally a physical problem with the monitor, you can plug in another computer to double check this on the monitor, but usually this means the monitor will need replacing.

If a monitor does need replacing, it's very good news that over the past 18 months the prices of flat screen monitors have come right down in price, a 17" screen can now be picked up for around £100 which is amazing considering prices of £300 less than 3 years ago.
