Troubleshooting
  
1. Your computer does not recognize the port replicator of the monitor.   
Disconnect the USB cable from your computer, wait at least five seconds, 
and reinsert  
it into the USB connector of your computer. If the problem persists, try connecting  
the USB cable to a different USB connector of your computer.  
2. The monitor display is blank.   
Verify that the computer connected to the port replicator of the monitor is 
running  
correctly and is not in Standby or Hibernate mode.   Verify that the display drivers are 
installed following the installation steps and the icon for the port replicator is visible 
in the taskbar notification area.  
Verify that the video output function is not disabled.   
Verify the following connections:   
The USB 2.0 cable is correctly connected to your computer.   
The USB 2.0 cable is correctly connected to the port replicator of the 
monitor.  
If the problem persists, disconnect all connections of the port replicator, 
uninstall 
the port replicator device drivers, and then reinstall the device drivers.  
3. When you are in the Extend mode and playing back video clips, only 
one video 
clip is visible.   
When in the Extend mode, only one video playback application can be 
used at a time. 
If multiple video clips are played back, only one video clip 
is visible to the user. This 
also applies to Web pages with embedded video 
clips. To view these Web pages, move  
one page to the computer screen and the other to the monitor.
   
4. You cannot play back DVD on the monitor but can play it back on 
your notebook 
computer display.   
Some computers do not support the certified output protection protocol 
(COPP), and 
you will not be able to play back the protected DVD on the monitor .To play back  
the DVD on the monitor, you can connect the monitor to the VGA connector on 
your notebook computer and extend the display to the monitor.  
5. You cannot hear anything through your computer speakers or you can 
not use the 
audio connectors on the computer.   
Your computers default to the USB audio when the port replicator is 
connected,  
disabling your notebook computer built-in speakers and audio connectors.  
To  enable  your  computer  built-in  speakers  and  audio  connectors,  do  the 
following:  
A. Click 
L2230x Wide USB Port Replicator Monitor icon 
in the taskbar
                          notification area. The pop-up menu opens.
