Known issues - Windows 2000

Installation of DisplayLink driver on Windows 2000 SP4 requires patch SP4 Rollup 1. This is

available from www.microsoft.com. See Microsoft Knowledge Base article KB891861.

It is important to check in Windows 2000 that full USB2 is available, otherwise performance will

be impaired. To do this, look in Device Manager under Universal Serial Bus Controllers for an

item called "USB 2.0 Root Hub". If it is not there then performance will be USB1. (1188)

On Windows 2000, when many devices are attached to the PC and the PC is hibernated then

woken up, not all the devices come back to life immediately. It is occasionally necessary to detach

and reattach the USB connection to a device to coax it back to life. (1293, 1302)

On a Windows 2000 system where only a DisplayLink screen is enabled, locking the screen and

then disconnecting it could cause all the other screens to remain unusable. Reconnecting the

DisplayLink screen solves the issue. (4501)

Foreign language support on Windows 2000 has not been fully tested.

Known issues - other

When fast user switching to an user account without administrative privileges and then logging

off, the DisplayLink screens may go black. (4446)

In PowerPoint, the "Display slide show on:" menu has a bug which means that it does not work

when there are gaps in the numbering of enabled displays (as shown in WDP). Users of PowerPoint

2007 can get round this by using "Show presentation on:" in the ribbon, rather than the "Set up

slide show" box. (2337)

CRT monitors may show speckles at very high resolutions. This is because the DisplayLink device

cannot always support the high pixel clock required with high CRT refresh rates. (2155)

The ATI Catalyst Control Center is a tool provided on machines with AT! graphics cards for

managing extra screens. Some versions of this tool crash in the presence of DisplayLink software.

This has been observed with versions since AT! driver version 8.360. The workaround is to

uninstall the ATI Catalyst Control Center. (2054)

After a reboot, the numbers used in Windows Device Properties to identify the attached screens

may change. This is normal. (596)

F2. Video players, rendering technologies and applications

-------------------------------------------------------------------------------

On Vista XDDM, video support is very limited. With extended screens, video or DVD playback

are not supported in general. Exceptions:

PowerDVD7 and Quicktime are able to display video on a DisplayLink attached display, so long

as that display is the primary display. Video is not supported in clone mode. It works, but exhibits

poor performance. (1495)
