Using the DisplayLink Software
This section describes how to use DisplayLink’s Software. The section is divided into sub-sections relating to your operating system.
Note: The terminology for "mirror mode",can vary between operating systems and the DisplayLink GUI. The terms
“Clone”, “Mirror” and “Duplicate” areinterchangeable and provide the same function of making the contents of the 2 selected displays identical..
Behaviour on first connect
When connecting a device based on the DL-3x00 family, the firmware version will be checked by the host software. If they do not match, the firmware on the device will be updated. While the firmware is updating, a window similar to that shown below will be shown.
This process may take up to 20 seconds. Once complete, your device should begin to function.
Device/Monitor Detection
The DisplayLink System tray GUI, covered below, will only be available when a DisplayLink device is detected on the
USB bus.
When using a DL-1x0 or DL-1x5 based product, a new monitor will also be added in Windows Display Properties, even if there is no monitor connected to the device.
DL-3x00 devices now support monitor detect, therefore a new display will only be available once the device is connected to the PC AND a monitor is attached to the video output of the device.
Resolution Support
When a monitor is connected to a DisplayLink device, the DisplayLink host software reads the supported modes from

Windows Display Properties. The DisplayLink software will use the montior’s preferred mode by default.

Fit to TV
What is Fit to TV?
If using your DisplayLink product to connect to a TV, all of the Windows desktop may not be available. Many TVs will automatically 'overscan' the image they get by cutting off the borders and filling the screen with the image. On some
TVs it may be possible to turn this 'overscan' off in your TVs settings menu, consult your TVs User Manual to see if this is an option for you. If you can do so, then you will not need to use the Fit to TV function of the DisplayLink
UI.
Fit to TV can be used to reduce the size of the Windows desktop on the TV screen.
Notes: Fit to TV only works in extend mode. If choosing the option while in mirror mode, the DisplayLink screen will change to extend and be placed above the laptop screen in Windows Display Properties.
Fit to TV will only operate correctly when one DisplayLink device is connected. It is not designed to work on multiple
DisplayLink screens.
Fit to TV does not support rotated modes.

The following section provides additional information on the use of the DisplayLink USB Graphics software.
DirectX 10 Game support
This software release contains support for some DirectX 10 games on Windows 7. To improve the gaming experience, it is recommended that:
Antialiasing (AA) settings are turned OFF
Locking to vsync is turned ON
These options are usually configurable within the DirectX 10 game.
To play 3D games on a DisplayLink screen with reasonable performance the system specs must meet the game
“recommended” hardware specification, not just the minimum specification.
Monitor Calibration
Monitors can be calibrated with applications that use the Display Data Channel Command Interface (DDC/CI). Both the monitor and application must support DDC/CI for this to work. An example of an application that is now supported is
ScreenWhite .
DDC/CI is not supported on displays with integrated DisplayLink technology, for example mini monitors.
Media Playback
On Windows 7, Vista and Windows XP (in extend mode), the DisplayLink USB Graphics device can display media files and DVDs using the following media players:
Windows Media Player 11 ( http://www.microsoft.com/windows/windowsmedia/default.mspx
)
WinDVD 10 ( www.intervideo.com
)
PowerDVD 9 ( www.cyberlink.com
)
RealPlayer 11 ( www.real.com
)
The DisplayLink USB Graphics device can display media files and DVDs using most media players. Media playback in mirror mode (XP) or in Basic mode (Vista and Windows 7) is not recommended.
Using Multiple DisplayLink USB Graphics devices
The software supports up to six simultaneously USB attached screens. It is also possible that different sets of screens are being used at different times, for example two in the office and two at home. The software saves each screen’s display profile separately. This allows for different physical positioning, or different resolutions, of connected monitors in the office and the home.
Under NDA
Standby and Hibernate, Shut down and Restart
For V-Jack International
If the PC that the DisplayLink USB Graphics device is connected to is placed into standby or hibernate mode, the display goes blank. When the PC is again powered up (and unlocked if necessary) the connected monitor returns to the same mode as it was before stand by or hibernation.
If the PC is shut down, restarted and logged in, again the connected display returns to the same mode as it was before shutdown.

DisplayLink USB Graphics with Multiple Users
DisplayLink USB Graphics work with multiple users on the PC. The mode settings are saved for each user so each can use their own desktop configuration.
Disconnecting the DisplayLink USB Graphics
If the DisplayLink USB Graphics device is powered off or the USB cable is removed from the computer, the display blanks. All windows and icons move to the primary screen.
On reconnection or powering up of the DisplayLink USB Graphics device, the display returns to the same mode as it was before disconnection. However, windows and icons that were previously on the screen will not be moved back.
Supported Screen Modes
There are three components that make up the screen mode:
Resolution: The number of pixels displayed on screen horizontally and vertically.
Color Quality: The number of different colors that can be shown on the screen at the same time.
Refresh Rate: The speed that the entire screen is rescanned. Higher refresh rates reduce flicker.
Some monitors advertise the supported modes through the VGA or DVI connector. If this is the case, the DisplayLink
USB Graphics device identifies the supported modes from the monitor. If the monitor does not advertise the supported modes, the DisplayLink USB Graphics software chooses a set of common screen modes for the monitor.
Inferred Modes
Some modes in the DisplayLink GUI are shown with [ ] around them.
This occurs when connecting a monitor with a preferred mode higher than the maximum supported resolution of the

As these are inferred modes from the preferred mode of the monitor, they are not guaranteed to work with the display.
Error Messages
DisplayLink USB Graphics software occasionally displays user messages in a bubble in the notification area. The table below lists the user messages and their description.

Software Version 6.0
Message
Insufficient system resources exist to complete the requested service
The requested allocation size was too large
Incompatible Display Driver
The system cannot write to the specified device
Description
This can occur when entering extend mode with low system resources. The PC does not have enough memory to start an extend display.
Close down any unused applications. The situation may also be improved by rebooting the PC.
This can occur if trying to mirror a primary display with a resolution above
2300x1700 (4:3) or 2600x1500 (16:9).
This message will appear if the primary graphics card drivers installed are not
WDDM compatible. Windows 7 is not designed to operate without WDDM drivers.
Download and install the latest Windows 7 (WDDM) drivers for your primary graphics card.
This warning may be displayed in Windows XP after changing the display mode several times (e.g. Extend/Dock mode) from the DisplayLink GUI. If this happens, detach and reattach the device to restore normal operation.

Troubleshooting
Minor issues can generally be resolved by:
unplugging and re-plugging the DisplayLink device,
changing the display mode via the DisplayLink GUI, or,
changing the display mode via Windows Display Properties.
On Windows 7/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 Windows' Backup and Restore Center to recover.
