DisplayLink USB Graphics User Manual
Software Version 7.6
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. It is caused by
the OS memory becoming fragmented and the OS cannot allocate a frame buffer
for the USB display. If this happens, detach and reattach the device or reboot the
system to restore normal operation.

Troubleshooting

changing the display mode via the DisplayLink GUI, or,
changing the display mode via Windows Display Properties.

USB 3.0 support on Windows XP – Windows 7
USB 3.0 Host controllers on PCs are relatively new and the drivers may not be mature. Connecting DisplayLink devices
to a USB 3.0 port may show issues that are not present when connecting to USB 2.0.
