If using your DisplayLink product to connect to a TV, all of the
Windows desktop may not be available. This is because TVs can use
overscan, which prevents the edges of the image to be visible.
When showing a Windows desktop, overscan prevents the edgesof
the screen being visible, which can hide the task bar and icons.
Fit to TV can be used to reduce the size of the Windows desktop on the TV
screen.
Note: 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 does not
support rotated modes.

GUI. The following interface appears

the red border until it fits on the TV screen.
Note: Finer configuration of the size of the border can be achieved
by holding down the CTRL key and clicking the “+” and “ -”.
3. Once the red border is at the edges of the TV screen, click “Apply” to
resize the Windows desktop.

Additional Information
The following section provides additional information on the use of the USB Graphics Adapter 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 8, Windows 7, Vista and Windows XP (in extend mode), the USB Graphics Adapter can display media files and
DVDs using the following media players:
•Windows Media Player 11 (http://www.microsoft.com/windows/windowsmedia/default.mspx)
•Windows Media Player 12 (http://www.microsoft.com/windows/windowsmedia/default.mspx)
•WinDVD 8 (www.intervideo.com)
•PowerDVD 7 (www.cyberlink.com)
•RealPlayer 11 (www.real.com)
The USB Graphics adapter 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 USB Graphics Adapters
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.
Standby and Hibernate, Shut down and Restart
If the PC that the USB Graphics Adapter 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.
USB Graphics Adapters with Multiple Users
USB Graphics Adapters 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 USB Graphics Adapter
If the USB Graphics Adapter 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 USB Graphics Adapter, 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 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.
Error Messages
DisplayLink Graphics software occasionally displays user messages in a bubble in the notification area. The table below lists
the user messages and their description.
Some monitors advertise the supported modes through the VGA or DVI connector. If this is the case, the USB Graphics
Adapter identifies the supported modes from the monitor. If the monitor does not advertise the supported modes, the USB
Graphics Adapter 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 DisplayLink device
In this case, the preferred resolution of the monitor cannot be
supported. However we add lower resolutions of the same aspect
ratio to be tried with the monitor. Modes in square brackets [ ] imply
that these are modes not reported by the monitor, but have been
made available by the DisplayLink software for you to try.
As these are inferred modes from the preferred mode of the
monitor, they are not guaranteed to work with the display.
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.

this happens:
