7.1 Problems/Solutions
Problem: The display on the add-on monitor is blank.
Solutions:
If the monitor power is on (LED lights green in most cases), wait a moment for the monitor to show the video because some-
times it takes time for the add-on monitor to show the video. You can also reboot your system to try again. Make sure the
computer is not in standby or hibernation mode; this can cause the add-on monitor to be blank.
If the monitor power is in standby (LED lights red in most cases), check the connection. If the problem still exists, uninstall the
driver, unplug the adapter, and re-install the driver again.
Problem: The add-on monitor is flickering.
Solutions:
This is usually caused by a low refresh rate. To solve this problem, refer to the steps below.
In mirror mode, increase the refresh rate of the main monitor. This will increase the refresh rate of the add-on monitor.
In extended mode, increase the refresh rate of the add-on monitor.
Problem:
When playing an MPEG file with Windows Media Player on the extended monitor, the display becomes abnormal when switching
it to full-screen mode.
Solution:
Upgrade the Windows XP from SP1 to SP2.
Problem:
When playing the video in full-screen mode, the motion is not smooth.
Solutions:
Reduce the resolution of the display to 640 x 480 or 800 x 600.
Use the adapter in extended mode.
Terminate any other CPU intensive applications running on the computer.
Some media players require DirectX hardware support to correctly operate, so try a different media player that requires less
DirectX support.
Drag the media player to the add-on screen and close the player. Restart the player. It should open on the add-on monitor.
Now try playing the media file again.
Try reducing the hardware acceleration level of the primary display (NOT the add-on monitor) to levels 1, 2, or 3 and restarting
the media player. You can find the hardware acceleration by right-clicking on your desktop and click on Properties—>
Settings—>Advanced—>Troubleshoot. Some players use this setting even when playing on a different display.
The video playback may be unusual when the add-on monitor is mirroring the primary display and there is another extended
screen connected to the computer. The extended screen must be disabled before the content will be correctly cloned to the
add-on monitor.
