properly.
• 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
65 and 66.)

turn the power on again.
The video from D-Sub input terminal does not appear
correctly.
• Is the setting for D-SUB of INPUT SELECT on the SETUP
menu correct? (See page 28.)
• Is the input signal compatible with this monitor? (See pages
65 and 66.)
The video from the DisplayPort does not appear properly.
• Does the DisplayPort cable support 4K, and is it
DisplayPort standard compliant? The monitor will not work
with cables that are not standard compliant.

• Load noises from outside may be interfering with normal
operation. Turn off the main power and turn it on after
waiting at least 5 seconds, and then check the operation.
The input mode changes automatically.
• When NO SIGNAL AUTO INPUT SEL. is ON and
the current video signal input stops, the input mode
automatically changes to the mode of an active video
signal.
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 video does not appear properly even after the
DisplayPort STREAM setting is changed.
• Try restarting the monitor and computer.
• Is the video card MST (Multi Stream Transport) compatible?
If not, set to SST (Single Stream Transport).

“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 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.
