With Vista, a maximum of four DisplayLink screens are supported on machines with Nvidia
graphics. In certain rare cases, exceeding this has been seen to cause repeated serious crashes.
(1781)
On Vista WDDM, older versions of Nvidia drivers with versions prior to 7.15.11.146 can behave
badly in the presence of DisplayLink software. For instance they can cause blue screens when
applications are maximised on DisplayLink screens. Also, if DisplayLink devices are attached or
detached during restart, it may be necessary to press the reset button on the PC to restore normal
functioning. (2119)
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.
