10. Troubleshooting

Q1: add-on monitor remains blank

• Power LED on monitor is green: check whether the computer is not in standby or hibernate mode.

Always allow a few moments for the monitor to initialize. Should this take too long (e.g. more than

2 minutes) try to reboot the computer.

• Power LED on monitor is red: check whether all physical connections are properly made. If this is

the case and the problem remains, uninstall the driver, unplug the adaptor and reinstall the driver.

Q2: add-on monitor is flickering

• This is usually due to a low refresh rate.

• In mirror mode, increase the refresh rate of the main monitor. This will also increase the refresh

rate on the add-on monitor.

• In extended mode, increase the refresh rate of the add-on monitor.

Q3: Windows Media player messes up extended monitor in full screen mode

• This problem usually occurs under Windows XP SP1 and can be solved by upgrading to Service

Pack 2 (SP2).

Q4: playback video motion is not smooth in full screen mode

• Try to reduce the resolution of the monitor

• Use the adapter in extended mode

• Terminate other CPU-time consuming applications.

• Use a media player that requires less DirectX support.

• Drag the media-player to the add-on screen and close it. Restart the player. It should open on the

add-on screen. Try playing the media file again.

• Reduce the hardware acceleration level of the primary display (not the add-on monitor) and

restart the media player. Go to the display settings of the operating system. Right click anywhere

on the desktop, select ‘Properties’ and select ‘settings’. Select ‘Advanced’, tab ‘Troubleshoot’ and

move the slider to the left.

• When using both extended and mirrored screens, disable the extended screens.

Q5: In extended mode, a black border is shown around the desktop of the add-on monitor

• The resolution of the add-on monitor is set higher than the resolution of the primary monitor.

When possible, set the same resolution on both monitors.
