Care and Maintenance
Care
z  Avoid exposing your monitor directly to sunlight or other heat source. Place
your monitor away from the sun to reduce glare.
z  Put your monitor in a well ventilated area. Do not place anything heavy
on top of your monitor.
z  Make certain your monitor is installed in a clean and moisture-free area.
z  Keep your monitor away from    magnets, motors, transformers, speakers,
and TV sets.
Safety Tips:
z  If smoke, abnormal noise or odor came out of your monitor, switch off the
power immediately and call your service center.
z  Never remove the rear cover of your monitor cabinet. The display unit inside
contains high-voltage parts and may cause electric shock to human bodies.
Never try to repair your monitor yourself. Always call your
service center or a qualified technician to fix it.
Troubleshooting
No power
● 
Make sure A/C power is securely connected to the power adapter
and the power supply is firmly connected to the monitor.
 Plug another electrical device into the power inlet to verify that
the outlet is supplying proper voltage.
 Make sure all short cables are installed.
Power on but no screen image
 
Make sure the video cable supplied with the monitor is tightly
secured to the video output port on back of the computer. If not,
tightly secure it.
 Adjust brightness.
Wrong or abnormal colors
 If any colors (red, green, blue) are missing, check the video cable
to make sure it is securely connected. Loose or broken pins in the
cable connector could cause an improper connection.

Connect the monitor to another computer.
