There Is No Sound; The Projected Image Is Blurred - Canon WUX7500 User Manual

Troubleshooting
Cause
The computer is set to
dual screen (multi-
display) mode.
The image files are not
compatible with USB File
Browser.
The LAN cable (shielded
twisted pair) is not
connected correctly.

■ There is no Sound

Cause
The audio cable is not
connected correctly.
The MUTE function is
enabled.
The volume level is
adjusted to the
minimum.
An audio cable with a
built-in resistor is used.
Audio in terminal select
is [Off].

■ The Projected Image Is Blurred

Cause
The image is out of
focus.
The distance to the
screen is too short.
The projector is not
placed straight in front of
the screen.
Countermeasure
If dual screen mode is selected, change the
computer display output to mirroring mode.
The output setting method varies among computer
manufacturers. For more detailed information, refer
to the manual that came with your computer.
Projection from USB flash drives requires JPEG
images with a resolution not exceeding 10912x8640,
single-byte alphanumeric file names, and a FAT-
formatted drive.
When [LAN] or [HDBaseT] is selected in the [Input]
menu, check whether the LAN cable (shielded
twisted pair) is connected to the projector correctly
(P81).
Countermeasure
Check the audio cable connection (P79).
Press the MUTE button on the remote control (P37).
Press the VOL button on the remote control or the
VOL+ button on the side control to adjust the volume
level (P33, P37).
Use an audio cable without a built-in resistor.
Change the Audio In terminal to the appropriate
setting (P160).
Countermeasure
Adjust the focus (P46).
Check whether the distance to the screen is
appropriate (P61).
Check whether the projector is placed obliquely to
the screen. A slight error in the projection angle can
be corrected through the keystone adjustment
function (P101).
