The video from the PC/AV HDMI
input terminal does not appear
properly
• Is the seng for HDMI of INPUT SELECT on the OPTION menu correct?
• Is the HDMI cable HDMI standard compliant? The monitor will not work with cables that
are not standard compliant.
• Is the input signal compable with this monitor?
The video from PC D-SUB does
not appear correctly
• Is the INPUT SELECT seng on the OPTION menu correct?
• Is the input signal compable with this monitor?
Control buons do not work.
There is no picture.
• Load noises from outside may be interfering with normal operaon. Turn o the power
and turn it on aer waing at least 5 seconds, and then check the operaon.
The input mode changes auto-
macally.
• When the AUTO INPUT CHANGE is ON and no signal is present in a selected input mode,
the AUTO INPUT CHANGE automacally 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 response of the touch screen
is slow. Some parts of the screen
do not respond.
• Is the screen exposed to direct sunlight or other strong light? The touch panel uses infra-
red rays and thus may not operate correctly.
• Is there an obstacle between the infrared transmier/receiver and the stylus or your n-
ger? An obstacle will prevent correct operaon. If your ngers or a sleeve are too close to
the screen, correct operaon will not be possible.
• Is the infrared transmier/receiver dirty? Gently wipe o any dirt with a so cloth.
• If the touch panel is touched with a small p less than about 3/16 inch (4 mm) x 3/16 inch
(4 mm), the touch may not be detected by infrared and correct operaon will not take
place.
• When starng your computer or connecng 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
transmier/receiver and incorrect operaon will result.
Power LED ashes RED
“STATUS [xxxx]” appears in the
corner of the screen.
• There is a problem with the monitor. Turn o the monitor and contact InFocus Technical
Support.
"AUTO DIMMING" is displayed • When the internal temperature of the monitor rises excessively, the brightness of the
backlight automacally decreases in order to prevent a further temperature rise. If you at-
tempt 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
aect the monitor’s performance.
