T1421 Wide Flat Panel Monitor User’s Guide

 

 In some software application programs that utilize certain direct draw commands such as some 

2D-Games, the display on the Lenovo

 LT1421 Wide USB

 monitor will not be supported. If you 

want to play these games in full screen, we suggest you disconnect the Lenovo

 LT1421 Wide USB

 

monitor. 

 

 This product is unable to enter full screen DOS mode when using the Lenovo

 LT1421 Wide USB

 

monitor. 

 

 

Problem 

Solution(s) 

The monitor does not turn on 

Check the connections. Make sure 
the USB cable is firmly connected 
to the monitor. 
Disconnect and reconnect the USB 
cable. 
Check the condition of the USB 
cable. If the cable is frayed or 
damaged, replace the cable. If the 
connectors are soiled, wipe them 
with a clean cloth. 

The screen is blank, although 
the power is on 

Make sure the USB cable is 
properly connected to the 
computer. 
Make sure the computer is on and 
working. The computer may be in 
sleep or power-saving mode, or 
displaying a blank screen saver. 
Move the mouse to "wake up" the 
computer. 

The picture "bounces" or moves 
in a wave-like pattern 

Move electrical devices that may 
cause electrical interference away 
from the monitor. 

Minor issues can generally be resolved by: 

 unplugging and re-plugging the DisplayLink device, 

 changing the display mode via the DisplayLink GUI, or, 

 changing the display mode via Windows Display Properties. 

 

On Windows 7/Vista WDDM (Aero and Basic) 
 
DisplayLink software works closely with the graphics card and there may be interoperability issues 
with some graphics cards. If this happens: 

1. Try to upgrade to the latest graphics drivers. 
2. Try to upgrade to latest DisplayLink software. 
3. Report the issue via your support channel. 
4. If necessary, boot into Safe Mode and use Windows' Backup and Restore Center to recover.
