F.. Summary of Software State and Issues - Vista XDDM, XP, 2K
=====================================================================
Fl. Normal use
-----------------------
System behaviour with up to six DisplayLink attached screens has been well tested. Testing covers
plug/unplug, mode changes, playing video, hibernate, sleep/standby, multiple users, different user
rights, attached screen as primary screen, attached screen as only screen, and other aspects.
There are many annoyances and intermittent issues. General recommendations when something
goes wrong:
- try detaching then reattaching the DisplayLink device's USB cable
- try changing its display settings using the DisplayLink GUI or the
Windows Display Properties dialog box.
Known issues - hibernate / sleep / monitor power save / screensavers
On all OSes, the desktop background is occasionally missing after restart or after resume from
sleep or hibernation. The screens are still usable, and the background can be set again to the
desired picture. (2154, 2072)
On all OSes, detaching or attaching DisplayLink attached screens while a screensaver is running
may cause strange effects. Sometimes it is necessary to detach and reattach the DisplayLink
attached screen after exiting the screensaver. (1984)
3D screensavers do not run well on DisplayLink devices and can cause flicker and/or decreased
graphics performance. This is on all OSes. (1150, 1177, 4426)
When the machine is set to ask for a password after standby / sleep / hibernate / screensaver etc,
sometimes the login screen displays on all attached screens and sometimes it displays on a single
screen only.
If devices are detached from the PC before going into standby, then reattached during standby,
very occasionally they may not resume when the PC comes out of standby. If this happens, detach
and reattach the devices to make them work again. (1492)
