On Vista WDDM, Nvidia 5 series graphics cards with driver version 7.15.10.9685 cause rundll32
crash messages in the presence of DisplayLink software. If you have such a card, please update to
a more recent graphics driver version. (3077)
On some Nvidia SLi systems, it is not possible to enable or disable SL1 mode while a DisplayLink
screen is attached. (3147)
Triple SLi systems are not supported. (3146)
DisplayLink software is currently compatible with Intel/ATI hybrid graphics architectures.
Nvidia hybrid platforms are not supported yet. (3068)
E2. 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 minor issues. General recommendations if something goes wrong:
- detach then reattach the DisplayLink device’s USB cable
- change display settings using DL-GUI
- change display settings using WDP.
Known Issues - Hibernate / sleep / monitor power save / screensavers
On Vista, very occasionally, DisplayLink devices fail to resume from hibernation or sleep.
This is due to issues in the Vista USB subsystem.
Hotfix http://support.microsoft.com/kb/941600 should help. This is believed to be fixed in
Vista Service Pack 1. (2126)
On Vista WDDM, DisplayLink attached screens can be slow when resuming from hibernation
or sleep. This is a Vista problem and is believed to be improved in Vista Service Pack 1. (2165)
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)
