Known Issues - General
DisplayLink screens are not supported on systems with two graphics cards used simultaneously
(supporting separate screens, or in ATI Crossfire configuration). Two graphics cards in Nvidia SLI
configuration are supported. (1704, 4441)
DispayLink software may cause blue screens on software configurations where WDDM drivers
from different manufacturers have been installed on the same system, even if just one graphics
card is present. (4323)
On Vista WDDM, TMM does not appear when DisplayLink screens are attached. It works normally
when no DisplayLink screens are attached. (2569)
On some systems with hybrid graphics architectures a maximum of 3 DisplayLink screens is
supported when in High Performance GPU mode. (4459)
On a hybrid machine with DisplayLink software installed do not change the bios settings to ATI
only or Intel only.
If you need to change those BIOS settings please first uninstall the DL software, then reinstall it
once the new settings have been applied. (4339,4506)
On Vista WDDM, very occasionally, if the DisplayLink screen is primary with the main screen
off, then the DisplayLink screen flashes continuously when resuming from hibernation. To cure
the problem, detach and re-attach the DisplayLink screen. To prevent the problem, set the PC to
require a password when coming out of hibernation. (2835)
On Vista WDDM, very occasionally, if the DisplayLink screen is primary with the main screen
off, then both the main and DisplayLink screens may show corruption when resuming from
hibernation. To cure the problem, enable and disable the main screen. (3219)
On Vista WDDM aero, DisplayLink software can cause some PCs to become more susceptible to
TDRs (Timeout Detection and Recovery).
More info at http://wwiv.microsoft.com/whdc/device/display/wddm_timeout.mspx.
Suggested workarounds are (1) upgrade to the latest drivers for the native graphics card;
(2) increase TDR timeouts as described in the linked article. (3217)
Known Issues - Intel GMA Integrated Graphics
Some older versions of Intel GMA drivers will cause corruption on the DisplayLink screen.
The solution is to upgrade them to version 7.14.10.1111 or later. This is with Vista WDDM.

Users of Vista WDDM with Intel graphics should exercise caution if using two or more
DisplayLink screens at a time. Very occasionally, mode changes or detach/reattach of two
DisplayLink devices at once has been observed to cause a complete machine lock-up. (2264)
