Skype video does not work on DisplayLink screens with Windows XP. This is because Skype
video uses VMR9, which is supported by DisplayLink software on Vista WDDM, but not on
Vista XDDM or on XP. Trying to use skype video on XP may cause black screens or freeze the
DisplayLink attached screen. (1651)
On XP, W1nDVD may crash when trying to play Bluray with the DisplayLink screen as the
primary screen. (3785)
When using a display in mirror mode, changing the rotation setting can cause the display to go
into extend mode. Setting the display back to mirror mode will show the correct rotation. (2261)
Occasionally, on rotating a DisplayLink screen the monitor may freeze, change resolution or go
black. This is most likely if several screens are attached. To recover, detach and reattach the
DisplayLink screen. (4061)

and software-first. USB drivers have been signed.
Known issues
On Windows 2000, DisplayLink software fails to install on PCs where Service Pack 4 was installed
before installing a MUI pack. This is a Windows issue - see Microsoft Knowledge Base article
263212. To work round this problem, go to Control panel, Regional Options, select the General
tab and change the Menus and Dialog combo box to English. You will need to log off, and log back
on. Install DisplayLink software, and then set the language settings back to their original settings.

Do not attach two new DisplayLink devices at once as software for one of them may fail to install.
Instead, fully install one device and see it working before attaching a second device. (2022)
If you attach a new DisplayLink device, allow software to start installing, then cancel the install
part way through, hardware-first install may no longer work. To complete the install, it may be
necessary to run setup.exe directly. (1573)
Virus checkers set to very high security may prevent the installer from running. They should be
set to lower security during installation and restored to high security once installation is complete.

When installing, make sure that only a single user is logged into the PC. That user needs
administrator privileges. (1112)
