•   When the internal temperature of the monitor rises 

excessively, the brightness of the backlight decreases 
automatically in order to prevent high-temperature-related 
problems. When this occurs, the Power LED flashes red 
and green alternately.

•   If the internal temperature rises further, the monitor 

automatically enters standby mode. (The Power LED 
continues flashing red and green alternately.) 

•   Remove the cause of the excessive temperature rise.

-  If the monitor enters standby mode due to a rise in 

temperature, to return to normal display, turn the power 
switch off and then back on again. The monitor, however, 
will enter standby mode again if the cause of the 
temperature rise is not eliminated. (See page 8.)

-  Check whether the monitor is placed at a location where 

a quick rise in temperature is likely. Internal temperature 
rises quickly if the vents on the monitor are blocked.

-  Internal temperature rises quickly if dust accumulates 

inside the monitor or around the vents. Remove dust if 
possible. Ask SHARP dealer about removing internal dust.

  When mounting the monitor, be sure to use a wall-mount bracket that complies with the VESA-compatible mounting method. 

SHARP recommends using M6 screws and tighten the screws. 

Note that screw hole depth of the monitor is 3/8 inch (10 mm). Loose mounting may cause the product to fall, resulting in 

serious personal injuries as well as damage to the product. The screw and hole should come together with over 5/16 inch  

(8 mm) length of thread. Use a bracket which has been approved for UL1678 standard, and which can endure at least 4 times 

or more the weight of the monitor.

The monitor supports the VESA DDC (Display Data Channel) standard.

DDC is a signal standard for plug and play between monitors and computers. Information about resolution and other parameters 

is exchanged between the two. This function can be used if the computer supports DDC and it has been configured to detect 

plug-and-play monitors.

There are several types of DDC, depending on the communication method used. This monitor supports DDC2B.
