Message Description
Insufficient system resources
exist to complete the requested
service
This can occur when entering extend mode with low system resources. The PC does
not have enough memory to start an extend display.
Close down any unused applications. The situation may also be improved by
rebooting the PC.
The requested allocation size
was too large
This can occur if trying to mirror a primary display with a resolution above
2300x1700 (4:3) or 2600x1500 (16:9).
Incompatible Display Driver
This message will appear if the primary graphics card drivers installed are not
WDDM compatible. Windows 7 is not designed to operate without WDDM drivers.
Download and install the latest Windows 7 (WDDM) drivers for your primary
graphics card.
The system cannot write to the
specified device
This warning may be displayed in Windows XP after changing the display mode
several times (e.g. Extend/Dock mode) from the DisplayLink GUI. If this happens,
detach and reattach the device to restore normal operation.

Troubleshooting
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.
