LCD Monitors troubleshooting

Troubleshooting PC Monitor Problems

No matter what brand or type of PC monitor you have, it might not always run smoothly, and you may occasionally run into some problems that will need to be fixed. If you have already experienced a problem, there are a few steps you can take to do your own troubleshooting.

Check Connections

If you cannot get an image to display on your monitor, it is important to check the cables and verify that they are connected correctly.

All monitors use a power cable, which should be plugged into a surge protector (to protect your investment in case of surges in electrical power), though any functional, three-prong wall outlet will work.

LCD monitors will either make use of a VGA input or DVI input (some have both), while older CRT monitors will mostly use the VGA format. Make sure you have the right type of cable to connect to both your monitor and your computer. If your monitor only offers DVI input and your PC only offers VGA (or vice versa), adapters are available to easily convert between formats.

Make sure that the VGA or DVI cable is tightly connected to your computer and to your monitor. If this cable becomes even slightly dislodged from its connector, the picture can go out, which is why it is important to tighten the small thumb screws on the ends of the video cable.

Adjust Settings

Though you should not need to adjust your monitor's settings too often, room lighting conditions and several other factors can affect or alter the image displayed by your monitor and its viewability. This would include problems such as the image stretching off the viewable area of the screen, flickering and washed-out colors.

To access your monitor's on-screen display (OSD) for settings, use the small buttons on your monitor beneath the screen or on the side (the location varies depending on your brand and model). If you own a CRT monitor, you will have settings such as contrast, brightness and refresh rate (which decreases flickering when increased).

LCD monitors will have a color temperature setting that helps compensate for images that appear too blue (9000K range) or too red (6500K range), and the luminance setting which adjusts the brightness of your screen.

Feel free to adjust all of the settings and find the optimal image, as most monitors also have a reset function within the settings menu which reverts all adjusted settings back to their factory defaults when necessary.
