If there is no image on the screen or a 
Not Optimum Mode,Recommended Mode 1680 X 
1050 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.
