Your monitor provides a self test feature that allows you to check whether your monitor is functioning properly. |
 |
- Turn off both your computer and the monitor.
- Unplug the video cable from the back of the computer.
- Turn on the monitor.
|
If the monitor is functioning properly, you will see a white box with a blue border and red text inside as shown in the following illustration:
The three boxes inside the border are red, green and blue. |
|
Failure of any of the boxes to appear indicates a problem with your monitor. This box also appears during normal operation if the video cable becomes disconnected or damaged. |
- Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
|
If your monitor screen remains blank after using the previous procedure, check your video controller and computer system; your monitor is functioning properly. |
 |
|
 |
If there is something wrong with the input signal, a message appears on the screen or the screen goes blank although the power indicator LED is still on. The message may indicate that the monitor is out of scan range or that you need to check the signal cable. |

The location and the position of the monitor may influence the quality and other features of the monitor.
- If there are any woofer speakers near the monitor, unplug and relocate the woofer to another room.
- Remove all electronic devices such as radios, fans, clocks and telephones that are within 3 feet (one meter) of the monitor.
- Degauss the monitor if any devices were removed from the area.

- A monitor recreates visual signals received from the PC. Therefore, if there is trouble with the PC or the video card, this can cause the monitor to become blank, have poor coloring, noise, Sync. Out of Range, etc. In this case, first check the source of the problem, and then contact a service center or your dealer.
- Judging the monitor's working condition
If there is no image on the screen or an "Sync. Out of Range" message comes up, disconnect the cable from the computer while the monitor is still powered on.
- If there is a message coming up on the screen or if the screen goes white, this means the monitor is in working condition.
- In this case, check the computer for trouble.
