Self-Test Feature Check  |  Warning Messages |  Environment |  Useful Tips
 
Your monitor provides a self test feature that allows you to check whether your monitor is 
functioning properly.  
 
 
 
 
 Self-Test Feature Check 
 
1. Turn off both your computer and the monitor.  
2. Unplug the video cable from the back of the computer.  
3. Turn on the monitor.  
 
						

							If the monitor is functioning properly, you will see a box in the illustration below.  
 
 
 
This box appears during normal operation if the video cable becomes disconnected or 
damaged. 
 
4. 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. 
 
 
 Warning Messages  
 
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. 
 
 
 
 Environment  
 
The location and the position of the monitor may influence the quality and other 
features of the monitor. 
1. If there are any sub woofer speakers near the monitor, unplug and relocate the woofer 
to another room.  
2. Remove all electronic devices such as radios, fans, clocks and telephones that are 
within 3 feet (one meter) of the monitor. 
 
 
 Useful Tips 
 
zA monitor recreates visual signals received from the computer. Therefore, if there is trouble with 
the computer or the video card, this can cause the monitor to become blank, have poor coloring, 
noise, Video mode not supported, etc. In this case, first check the source of the problem, and 
then contact the Service Center or your dealer.  
 
zJudging the monitors working condition  
If there is no image on the screen or a 
Not Optimum Mode,Recommended Mode 1440 x 
900 60 Hz 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.
