        DisplayLink Software Release: External Release Note
        Software Package: Acer LCD Monitor
        Version: 4.4.11455.0
        =====================================================================
        =====================================================================
        EXECUTIVE SUMMARY

        This is the R4.4 Product Release. It has completed system test, both
        in-house and externally. It is suitable for deployment to end-users.

        DisplayLink Software Release 4.4 delivers the following features:
        - Projector operation without reboot (POWR)
        - Better interaction with Vista Transient Multi-monitor Manager (TMM)
        - SDK for control of uninstallation
        - Bug fixes.

        Recommendations for use:

        If using with more than one device, make sure each device is fully
        installed and working before adding the next.

        Minor issues can generally be resolved by
        - detaching and reattaching the DisplayLink device
        - changing the display mode via the DisplayLink GUI, or
        - changing the display mode via Windows Display Properties.

        On Vista WDDM (Aero and basic): DisplayLink software works closely
        with the graphics card and there may be interoperability issues with
        some graphics cards. If this happens,
        (1) try to upgrade to the latest graphics drivers
        (2) try to upgrade to latest DisplayLink software
        (3) report the issue via your support channel
        (4) if necessary, boot into Safe Mode and use Vista's Backup and
        Restore Center to recover.

        Video: video generally works using the most popular video players on
        Vista WDDM aero. Video works in extend mode on XP. Video support is
        limited in other configurations such as on Vista WDDM basic and in
        mirror mode on XP.

        C. New Features
        ===============
        New features in R4.4 are:
        - Projector operation without reboot (POWR)
        - Better interaction with Vista Transient Multi-monitor Manager (TMM)
        - SDK for control of uninstallation
        - Bug fixes.

        Projector operation without reboot (POWR)
        -----------------------------------------
        This feature is available in some customer packages.

        It provides a restricted mirror-only mode after install / upgrade
        and before the associated reboot. This can be helpful for users
        attaching to a projector for the first time.

        There are some limitations in reduced-functionality mode:
        - only mirror mode is supported; no extend option is available
        - performance is reduced compared to normal operation
        - rotation is not supported
        - logon screens are not mirrored. The software is functional only
        within a logged-on user session.

        Better interaction with Vista Transient Multi-monitor Manager (TMM)
        -------------------------------------------------------------------
        The Transient Multi-monitor Manager (TMM) on Windows Vista detects
        newly attached monitors and configures their mode. DisplayLink software
        also watches for newly attached DisplayLink screens and configures 
        their mode. The two programs can interact badly with each other.

        With R4.4 software, the TMM settings work when there are no DisplayLink
        screens attached. DisplayLink software manages all screens when there 
        are DisplayLink screens attached.

        Users who attach a screen via the VGA or DVI port on their laptop
        will need to disconnect any DisplayLink screens, to use TMM to
        configure the screen.
        
        SDK for control of uninstallation
        ---------------------------------
        Some customers of DisplayLink bundle the DisplayLink installer /
        uninstaller in their own installer. This feature allows such
        customers to better control the uninstallation operation.

        Bug fixes
        ---------
        The following improvements have been made since R4.3 Maintenance
        Release 3 (4.3.9881):

        Always use correct display mode at first connect. (2554)

        Ensure that the monitor's preferred mode is used, in the situation
        where the DisplayLink device was first attached without a monitor
        present. (2699)

        Improve handling of resume from hibernation in the case where several
        screens are attached (2743, 2804)

        Fix problem that caused a DisplayLink screen to become disabled after
        log off / log on. (2735)

        Display suitable error message if cannot install/uninstall because user
        has insufficient privileges and UAC is off. (2514, 2762)

        Allow limited users who can elevate privilege using UAC to install /
        uninstall (2845, 2846)

        Allow installation by administrator who is not mentioned in the
        Administrators group. (2788)

        Fix occasional problem where a USB disconnect during connect caused the
        DisplayLink screen to offer a single display mode. (2445)

        Fix problem that could cause the DisplayLink systray icon to animate
        indefinitely and the screen to fail to come on, at first attach
        after reboot. (2621)

        Fix unhelpful user message "property.CORENOTINSTALLEDERROR" (2824)

        Fix corrupt VGA screen after returning from monitor power save with
        DisplayLink screen primary (2664)

        Updated some SDK documentation (2830)

        Fixed a problem in Vista XDDM mode, where unplug / plug of a
        DisplayLink screen could cause the PC to restart (2866)

        Ensure that we detect correctly whether extend and mirror drivers
        are loaded and prompt for a restart when they are not. Ensure that
        the GUI status behaves correctly when a reboot prompt is issued.
        This is on XP and on Vista XDDM. (2951)
        

        D. Note on Vista Modes
        ======================
        Normally, Vista is in WDDM mode. In this mode, Vista graphics drivers
        are used, and the Vista Aero Glass and Vista Basic looks are available.

        Vista PCs whose graphics drivers are not Vista ones run in XDDM mode.
        In this mode, the Aero Glass look is not available. PCs that were
        upgraded from XP to Vista and PCs with low-end graphics cards run in
        XDDM mode.

        DisplayLink software supports both modes in different ways, and the
        level of support and issues are different in the two cases.


        E. How to Install
        =================
        Important note: users who have v3.x ‘USB Display Adapter’ software
        installed in Add/Remove Programs must uninstall it before installing

        F. How to Use
        =============
        DisplayLink screens can run in three modes:

        - extend mode: the screen is part of the extended desktop
        - mirror mode: the screen copies the contents of the primary screen
        - off mode: the screen is black.

        Display modes can be controlled through the DisplayLink GUI (DL-GUI)
        and through the Windows Display Properties dialog box (WDP).

        DL-GUI
        ------
        This is an icon in the systray that looks like a monitor. Click on the
        icon to bring up the menu. You can control
        - screen resolution
        - colour quality
        - rotation
        - mode (extend, mirror, off)
        - extend position (right, left, above, below)
        - auto-update configuration
        - manual check for newer software.

        WDP
        ---
        To open WDP on XP / 2K
        - right-click on the desktop
        - select 'Properties' from the context menu
        - go to the Settings tab

        To open WDP on Vista
        - right-click on the desktop
        - select 'Personalize' from the context menu
        - click on Display Settings link

        To open WDP from DL-GUI
        - bring up the DL-GUI menu
        - click 'Advanced...'

        With WDP you can control
        - screen resolution
        - colour quality
        - extend position
        - primary screen
        - refresh rate
        - whether the device is enabled (= part of the extended desktop)
        or not (= mirror or off mode).

        K. Summary of Software State and Issues - Vista WDDM
        ====================================================
        K1. Vista WDDM graphics card support
        ------------------------------------

        Because of restrictions in Vista WDDM support for graphics cards, the
        DisplayLink software works closely with the graphics drivers for
        the PC's graphics card. We support interworking with single graphics
        cards from Intel, ATI, Nvidia and Via. We have interoperability
        tested against a representative selection of each of these cards, and
        continue to expand our test coverage in this area.

        We cannot exclude severe problems in the case of graphics cards or
        driver versions that have not been interoperability tested with
        DisplayLink software. Should such problems arise,

        - First, upgrade to the latest graphics drivers for your PC. Latest
        drivers can be found on the PC manufacturer's or graphics card
        manufacturer's website.

        - Second, upgrade to the latest DisplayLink software available for
        your device. Use 'Check now...' from the DisplayLink GUI to find and
        download latest software.

        - If this does not help, please inform your DisplayLink device
        manufacturer's support line. Please give these details:
        + PC make, CPU and memory
        + graphics card make, model and driver version.


        Known issues - general

        DisplayLink screens are not supported on systems with two graphics
        cards used simultaneously (supporting separate screens, or in SLi or
        Crossfire configuration). (1704)

        On Vista WDDM, TMM does not kick in when DisplayLink screens are
        attached. It works normally when no DisplayLink screens are
        attached. (2569)
     

        Known issues - Intel graphics

        Some older versions of Intel graphics drivers will cause corruption on
        the Nivo screen. The solution is to upgrade them to version
        7.14.10.1111 or later.  This is with Vista WDDM.	(2164)

        Users of Vista WDDM with Intel graphics should exercise caution if
        using two or more DisplayLink screens at a time. Very occasionally,
        mode changes or detach/reattach of two Nivos at once has been observed
        to cause a complete machine lock-up. (2264)


        Known issues - ATI graphics

        The ATI Catalyst Control Center is a tool provided by ATI to control
        ATI graphics cards. In the presence of DisplayLink attached screens,
        some parts of the tool, such as its adjustments submenu, do not work.
        This is on all OSes. (1596)

        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. This can cause problems when a
        screen is attached to the PC. To work around the problem, uninstall the
        ATI Catalyst Control Center.


        Known issues - Nvidia graphics

        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)


        K2. 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. This is on all OSes. (1150, 1177)

        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 - other

        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)

        Vista WDDM: it's best to avoid switching between 32 bit and 16 bit
        colour quality on DisplayLink attached screens. Occasionally, this
        causes the DisplayLink screen to stop working. Detach and reattach it
        to get it to work again. Very occasionally, this has caused a complete
        machine lock-up. (2070, 2260)

        On Vista WDDM, if a DisplayLink screen is primary, it is not possible
        for another DisplayLink screen to mirror it. (1870)

        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)

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

        On Vista WDDM, when using the DisplayLink GUI to set rotation,
        occasionally the screen rotation will fail to match the GUI's rotation
        setting. To fix this, apply the setting again, or detach and reattach
        the DisplayLink screen. (2186)


        K3. Video players, rendering technologies and applications
        ----------------------------------------------------------
        On Vista WDDM Aero, video playing largely works. Video playing and
        rendering using hardware overlays is not supported. The following
        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).

        This table shows what rendering interfaces are supported:

        Interface             Supported on Vista WDDM Aero?

        DxVA                  Yes, if supported by the GPU
        D3D                   Yes, but not if the DisplayLink screen is primary
        DirectDraw            Yes
        OpenGL                Yes, but not full screen, windowed only
        GDI+                  Yes, but not full screen, windowed only


        On Vista WDDM Basic, video is not supported. It may work in some
        cases but exhibits poor performance. It may stop working after an
        update from Windows Update that affects the graphics subsystem. (2028)

        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.

        With Vista WDDM, on some lower-spec PCs, videos on DisplayLink attached
        screens pause frequently for several seconds at a time. This is because
        there is insufficient system performance to display video smoothly.
        (1798)


        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)

        On Vista WDDM, video players sometimes use hardware overlays to display
        video. DisplayLink software does not support hardware overlays and
        these videos do not display on DisplayLink screens. Examples: PowerDVD
        7 uses overlays when playing DVDs and so cannot display DVDs on
        DisplayLink screens. vlc can be configured to use overlays and will not
        work on DisplayLink screens if so configured.	(1807)

        On Vista WDDM, some graphics-intensive applications use the GDI or
        OpenGL interfaces. On DisplayLink attached screens, such applications
        can display in a window but not full screen. Examples of such
        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, 2134)

        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.
        (2032)

        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)

        On Vista WDDM, a problem has been observed playing a Blu-ray disk. When
        two DisplayLink screens were attached, and a Blu-ray disk was inserted,
        the directly attached screen froze. To avoid this problem, ensure that
        only one DisplayLink screen is attached when attempting to play a
        Blu-ray disk. (2637)


        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

        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)

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


        Known issues - other

        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 ATI
        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 ATI 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)


        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)

        Note that Windows Media Player and RealPlayer do not play DVDs on
        extended or mirrored screens on Windows XP. This is the case whether
        the extra screens are DisplayLink screens or directly attached. (2802)

        On Windows 2000, video playing is not supported. (2708)


        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.


        Known issues

        On Windows 2000, DisplayLink software fails to install on PCs where
        Service Pack 4 was installed before installing a MUI pack. This is a
        Windows issue - see Microsoft Knowledge Base article 263212. To work
        round this problem, go to Control panel, Regional Options, select the
        General tab and change the Menus and Dialog combo box to English. You
        will need to log off, and log back on. Install DisplayLink software,
        and then set the language settings back to their original settings.
        (1010)

        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)

        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.

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