Regular maintenance of the monitor is recommended. 

Dust the rear cover of the monitor regularly using a soft, dry cloth. Dust on the rear 

cover may cause the cooling system of the monitor to fail. To remove stubborn 
dust, only use a moistened (not dripping) cloth which has been dipped in a mild 
detergent solution. See important notes below.   

To clean the LCD surface, apply a non-abrasive camera lens cleaner to a soft, dry cloth. 

Lightly wipe the cleaning cloth over the LCD surface in a circular motion. Avoid 
using an excessive amount of cleaner, and do not apply the cleaner directly on 
the LCD surface. Abrasive cleaners, solvent or other harsh chemicals might 
scratch the LCD surface.   

 

Image brightness may decrease after long-term use. In this case, the interior of the 
monitor may need to be cleaned. Do not attempt to clean the monitor yourself.

 Note: 

1.  Unplug the AC power cord before cleaning the monitor to avoid a shocking hazard. 
2.  When cleaning the monitor, avoid pressing too hard on the monitor surface. Excessive 

force can cause damage to the monitor. 

3.  Do not use paper products or similar items to wipe the LCD screen. These materials 

can easily scratch the LCD surface. Only use a soft dry cloth. 

4. 

Keep sharp objects, such as writing utensils and screwdrivers, away from the LCD 
surface to avoid screen damage.

 

5. 

Avoid cleaning monitors with solutions which contain ammonia, ethyl alcohol, 
acetone, toluene, ethyl acid, or methyl chloride. These chemicals will damage your 
monitor.
