        applications are Starcraft, Quake 3. Also, video players such as
        Windows Media Player, WinDVD fail to play in full screen mode on
        DisplayLink screens on some PCs. (1655)

        On Vista WDDM, applications such as games that use Direct3D will not
        display on a DisplayLink attached screen that is set to primary. (1815)

        Some players, including Windows Media Player, do not play well on
        DisplayLink attached screens which are set as primary. (2084)


        Known issues with specific players and applications

        On Vista WDDM, if Windows Media Player is moved to the DisplayLink
        screen and is then made full-screen, the screen blanks.  To get out of
        this situation, either double click on the blank screen and the player
        window is restored to non-full screen mode, or right click on the blank
        screen to invoke the player context menu and select exit full screen.

        Skype video is believed to be unreliable with Vista. It may cause
        crashes.

        On Vista WDDM, if WinDVD is asked to play High-Definition content on a
        DisplayLink screen, the content will not display and the player may
        crash. This is because the player uses hardware overlays, which are not
        supported by DisplayLink software. (1986)

        On vista WDDM, if PowerDVD 7 is playing video on a DisplayLink attached
        screen, and if the screen is rotated, then PowerDVD 7 crashes. The
        workaround is to apply rotation to the screen before launching PowerDVD
        7. (2013)


        K4. Installer and Auto-update function
        --------------------------------------

        The installer and auto-update function work on all supported operating
        systems, both hardware-first and software-first. USB drivers have been
        signed.


        Known issues

        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)

        On Vista WDDM, the machine may drop to basic mode when a new
        DisplayLink screen is connected. This is because of Vista's normal
        performance calculation when new screens are attached. Aero mode can be
        restored through Control Panel -> Windows Colour and Appearance -> Open
        classic appearance properties for more colour options -> Windows Aero.
        (2069)

        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. (935)

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

        On PCs where vbscript.dll is not registered with the DLLServer, the
        DisplayLink installer cannot run. (1824)

        AutoUpdate dialogs and menus are not yet localised in Hungarian,
        Portuguese and Traditional Chinese. Other languages are complete.


        L. Summary of Software State and Issues - Vista XDDM, XP, 2K
        ============================================================
        L1. 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. This is on all OSes. (1150, 1177)

        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)


        Known issues - Windows 2000

        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)

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


        Known issues - other

        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 Transient Multimonitor Manager (TMM) is a component of Vista that
        manages external screens. Unfortunately, it behaves very badly in the
        presence of DisplayLink software. It is therefore disabled when
        DisplayLink software is installed, and re-enabled when DisplayLink
        software is uninstalled. (1831)

        Some versions  of the ATI Catalyst Control Center crash in the
        presence of DisplayLink software. This has been observed with versions
        since ATI driver version 8.360. (2054)

        After a reboot, the numbers used in Windows Device Properties to
        identify the attached screens may change. This is normal. (596)


        L2. 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)

        On XP, video support is limited to players that support hardware
        overlays. In extend mode, the following media players work:

        - Windows Media Player 11
        (www.microsoft.com/windows/windowsmedia/default.mspx)
        - WinDVD 8 (www.intervideo.com)
        - PowerDVD 7 (www.cyberlink.com)
        - RealPlayer 11 (www.real.com)

        There is limited support for other video players, and for video in
        mirror mode.

        This table shows what rendering interfaces are supported:

        Interface             Supported on XP extend?

        DxVA                  No
        D3D                   No
        DirectDraw            Yes
        OpenGL                No
        GDI+                  No


        On all platforms, depending on the player, there may be problems if
        the video window is moved between screens while video is running. It
        may be necessary to close and restart the video player.


        Known issues - general

        Don't change the display mode, position or arrangement of attached
        screens while a video is running. This usually confuses the video
        player and the video may stop playing. (1982)

        Some players, including Windows Media Player, do not play well on
        DisplayLink attached screens which are set as primary. (2084)

        DVD movies will not play back if they are dragged to an extended
        DisplayLink screen while running. They play OK if the player
        starts up on the extended screen. (no bug number)


        Known issues with specific players and applications

        Skype video is believed to be unreliable with Vista. It may cause
        crashes (no bug number).

        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)


        L3. Installer and Auto-update function
        --------------------------------------

        The installer and auto-update function work on all supported operating
        systems, both hardware-first and software-first. USB drivers have been
        signed.

        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. (935)

        On PCs where vbscript.dll is not registered with the DLLServer, the
        DisplayLink installer cannot run. (1824)

        AutoUpdate dialogs and menus are not yet localised in Hungarian,
        Portuguese and Traditional Chinese. Other languages are complete.

        (Vista XDDM) Occasionally, after install and reboot, the DisplayLink
        devices are not operational. In this case, reboot again and they
        become operational. (969)
