INF7020 Hardware Guide
The video from the PC/AV HDMI 
input terminal does not appear 
properly
•  Is the setting 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 compatible with this monitor? 
The video from PC D-SUB does 
not appear correctly
•  Is the INPUT SELECT setting on the OPTION menu correct? 
•  Is the input signal compatible with this monitor?
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 auto-
matically.
•  When the AUTO INPUT CHANGE is ON and no signal is present in a selected input mode, 
the AUTO INPUT CHANGE 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 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 transmitter/receiver and the stylus or your fin-
ger? 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 (4 mm) x 3/16 inch 
(4 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.
•  There is a problem with the monitor. Turn off 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 automatically 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 
affect the monitor’s performance.
