Troubleshooting

56

The computer projected image is too big for the screen or appeared to be cut-

off 

My Window Media Player program works great on my computer, but the

movie window is dark on my projector, while the Media Player tools display

OK. 

The remote mouse function does not work.

Cause

Remedy

The computer's resolution does not 
match the projector's resolution.

1.

Make sure Auto Resize is set to On in 
the Image menu.

2.

Make sure the H Position and V Position 
settings are correct in the Image menu.

3.

Configure the computer's external 
display resolution to the projector's 
native resolution (1024 x 768 for 
PB8253/PB8263). If this option is not 
available, select one of the compatible 
listed in 

"Supported timing for PC 

(including DVI-I) input" on page 58

.

4.

Check if your presentation files are 
created for a different resolution.

The computer's external monitor 
setting is locked in 640 x 480. 

Cause

Remedy

The computer external display is set 
as a secondary display.

Change the Display settings. Click Start > 
Control Panel > Display > Settings > 
Advanced > Display. See you computer 
documentation for details, if you cannot find 
the Display settings by following the 
instructions above. Set the Monitor to Primary, 
and the Panel to Secondary. You will see the 
movie window on the projector image, while 
the Panel movie window will be dark.

Cause

Remedy

The USB cable is not correctly 
connected to the projector or 
computer.

Check the connection. See 

"Connecting a 

computer" on page 22

 for details.

If it still doesn't work, check the mouse driver. 
See the mouse documentation for details.
