  Example: To transfer the data of block 1 (0 to 31 levels) 
of red (R) data
UGRW01000000010002 … 0031C0
Command Block number 32 pieces of data
Checksum
One piece of data consists
of 4 digits.
*  If data is less than 4 digits, add a “0” (zero) to make it 4 digits.
*  The checksum field is the character string (ASCII) data of lower-order one byte which indicates the sum of the block number 
and 32 pieces of data in hexadecimal (0 to F).
Saving the GAMMA user data
Use the user data save command (UGSV) to save the transferred user data in the monitor.
If the data is not saved, it will be cleared when:
•  The main power switch is off
•  STANDBY MODE is LOW POWER and the monitor enters standby mode
Activating the GAMMA user data
To activate the transferred user data, select USER for GAMMA in the PICTURE menu, or send the corresponding control 
command.
Checking the GAMMA user data
Use the user data read commands (UGRR, UGGR and UGBR) to return 512 pieces of user data for each of the R, G and B 
colors. Divide the data into 16 blocks and return 32 pieces of data with each command. The value to be returned is not the value 
stored in the monitor, but the value in the temporary memory for display. (These values are the same when the user data save 
command (UGSV) above has been sent.)
TIPS
•  The user data is not initialized by RESET of the PICTURE menu. To initialize the user data, use ALL RESET of the 
FUNCTION menu. 
The GAMMA user data initialize command (UGRS) allows the initialization of the user data only.

Troubleshooting
If you are experiencing any problem with your display, before 
calling for service, please review the following troubleshooting 
tips.
There is no picture or sound.
•  Is the power cord disconnected? (See page 14.)
•   Is the main power switch off? (See page 17.)
•   Is the monitor in standby mode (the power LED illuminating 
in orange)? (See page 17.)
•   Make sure correct input mode is selected. (See pages 24 
to 25.)
•   If any external equipment is connected, make sure the 
equipment is operating (playing back).
Remote control does not work.
•  Are the batteries inserted with polarity (+,-) aligned? (See 
page 15.)
•   Are the batteries exhausted?
•   Point the remote control unit toward the monitor’s remote 
control sensor. (See page 15.)
•   Is the menu display hidden or is operation disabled? (See 
page 44.)
Sound from left and right speakers is reversed.
Sound is heard from only one side.
•  Are audio cables connected properly? (See page 13.)
•  Make sure audio cables for external speakers are 
connected properly: left and right cables may be reversed 
or one of the two cables may not be connected. (See page 
13.)
•  Check the setting of BALANCE for AUDIO menu. (See 
page 36.)
There is a picture but no sound.
•  Is the sound muted?
•  Make sure the volume is not set to minimum.
•  Are audio cables connected properly?
•  Is the setting of AUDIO SELECT on the SETUP menu 
correct? (See page 36.)
•  Is the setting for SPEAKER SELECT of AUDIO OPTION on 
the SETUP menu correct? (See page 36.)
Unstable video.
•  The signal may be incompatible.
•  Try the automatic screen adjustment when D-SUB1[RGB] 
or D-SUB2 are used.
•  If the top and bottom of the image are not horizontally 
aligned, set TOUCH PANEL MODE on the MONITOR 
menu to OFF.
The video from the HDMI input terminal does not appear 
properly.
•  Is the setting for HDMI1/HDMI2/HDMI3 of INPUT SELECT 
on the SETUP menu correct? (See page 36.)
•  Is the HDMI cable HDMI standard compliant? The monitor 
will not work with cables that are not standard compliant.
•  Is the input signal compatible with this monitor? (See pages 
67 to 68.)
The video from D-sub1 input terminal does not appear 
correctly.
•  Is the setting for D-SUB1 of INPUT SELECT on the SETUP 
menu correct? (See page 36.)
•  Is the input signal compatible with this monitor? (See page 
67.)
The video from D-sub2 input terminal does not appear 
correctly.
•  Is the input signal compatible with this monitor? (See page 
67.)
The video from DisplayPort input terminal does not 
appear correctly.
•  Is the input signal compatible with this monitor? (See page 
67.)
•  Is the DisplayPort cable DisplayPort standard compliant? 
The monitor will not work with cables that are not standard 
compliant.
Control buttons do not work.
There is no picture.
•  Load noises from outside may be interfering with normal 
operation. Turn off the power and turn it on after waiting at 
least 5 seconds, and then check the operation.
The input mode changes automatically.
•  When CONNECT AUTO INPUT SELECT is ON, the input 
mode automatically changes to that terminal when a video 
signal is input into the input terminal. 
For this reason, the input mode may change when the 
computer wakes up from system standby.
•  When the NO SIGNAL AUTO INPUT SEL. is ON and no 
signal is present in a selected input mode, the monitor 
automatically changes the selected mode to a mode where 
a video signal is present.
  The input mode may change in the following cases:
- When a computer is in standby mode.
- When video play is stopped with a playback device.
The touch panel does not respond.
•   Is the USB cable connected properly? (Touch Panel 
Settings Tool Operation Manual)
•   Have Touch Panel Settings Tool and Touch Pen Utility been 
installed? (Touch Panel Settings Tool Operation Manual, 
Touch Pen Utility Operation Manual)
•   Has the pen tip of the touch pen become worn? Replace 
the pen tip. (See page 20.)
•   Is the battery inserted in the wrong orientation (+, -) in the 
touch pen? (See page 19.)
•   Is the touch pen battery exhausted?
The response of the touch screen is slow.
Some parts of the screen do not respond.
A different place is touched
•   Is the screen exposed to direct sunlight or other strong 
light? The touch panel uses infrared rays and thus may not 
operate correctly.
•  Is there an obstacle between the infrared transmitter/
receiver and the touch pen or your finger? An obstacle will 
prevent correct operation. If your fingers or a sleeve are too 
close to the screen, correct operation will not be possible.
•  Is the infrared transmitter/receiver dirty? Gently wipe off 
any dirt with a soft cloth.
•   If the touch panel is touched with a small tip less than about 
3/16 inch (5.5 mm) x 3/16 inch (5.5 mm), the touch may not 
be detected by infrared and correct operation will not take 
place.
•   When starting your computer or connecting the USB cable, 
do not touch the touch panel. If you touch the touch panel, 
this may be detected as an element failure in the infrared 
transmitter/receiver and incorrect operation will result.
Power LED flashes red.
“STATUS [xxxx]” appears in the corner of the screen.
•   Hardware has a problem. Turn off the monitor and request 
repair from your SHARP dealer. 
(When STATUS ALERT is set to OSD & LED. This varies 
depending on the setting.)

When “AUTO DIMMING” is displayed.
•   When the internal temperature of the monitor rises 
excessively, the brightness of the backlight automatically 
decreases in order to prevent a further temperature rise. If 
you attempt to use 
 
 to adjust the brightness while 
the monitor is in this state, “AUTO DIMMING” is displayed 
and you cannot change the brightness.
•   Remove the cause of the excessive temperature rise.
The monitor makes a cracking sound.
•   You may occasionally hear a cracking sound from the 
monitor. This happens when the cabinet slightly expands 
and contracts according to change in temperature. This 
does not affect the monitor’s performance.
The Power LED is flashing in red and green alternately. 
When “TEMPERATURE” is displayed in the corner of the 
screen.
•   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, “TEMPERATURE” is 
displayed on the screen and the Power LED flashes red 
and green alternately. (When TEMPERATURE ALERT is 
set to OSD & LED. This varies depending on the setting.)
•   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 7.)
-  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.
