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.
• Are the AC adapter and power cord properly connected?
(See page 13.)
• Is the main power switch off? (See page 15.)
• Is the monitor in standby mode (power lamp is off)? (See
page 15.)
• If any external equipment is connected, make sure the
equipment is operating (playing back).
Sound from left and right speakers is reversed.
Sound is heard from only one side.
• Are audio cables connected properly? (See page 12.)
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 20.)
• Is the headphone (etc.) cable connected to the headphone
terminal?
The sound crackles.
• Turn down the volume.
With some input devices, the sound may crackle at high
volume.
Unstable video.
• The signal may be incompatible.
The video from DisplayPort input terminal does not
appear properly.
• Is the cable a certified DisplayPort cable? Use the supplied
cable. The monitor will not work unless a standards-
compliant cable is used.
• Is the input signal compatible with this monitor?
(See page 30.)
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) compatible? If not, set
to SST (Single Stream).
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.
• When you display the screen or clear the screen, the left
and right screen display timing may be slightly off; however,
this is not a problem.
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 ASUS
®
(When STATUS ALERT is set to OSD & LED. This varies
depending on the setting.)
Troubleshooting
dealer.
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 brightness adjustment button (
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 ASUS
®
dealer about removing internal dust.
