Self - Test  
Your monitor provides a self - test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly 
connected but the monitor screen remains dark, run the monitor self - test by performing the following steps:   
1. Turn off both your computer and the monitor.   
2. Unplug the video cable from the back of the computer or monitor. To ensure proper self - test operation, remove the HDMI, Digital (white connector), and 
the Analog (blue connector) cables from the back of the computer or monitor.   
3. Turn on the monitor. 
   
4. This box also appears during normal system operation, if the video cable becomes disconnected or damaged.   
5. 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 you use the previous procedure, check your video controller and computer, because your monitor is functioning 
properly.
