USB Display Adapter User's Manual
Q4: When playing the video in full screen mode, the motion is not smooth.
A: Try the following tips to improve the smoothness of the movie playback:

Reduce the resolution of the display to 640x480 or 800x600.

Use the adapter in extended mode.

Terminate any other CPU intensive applications running on the computer.
If you still have issues playing media content on the adapter, try the following steps:

As some media players require DirectX hardware support to correctly operate, try a
different media player which requires less DirectX support.

Drag the media player to the add-on screen and close the player. Restart the player
and 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. The hardware acceleration
can be found by right-clicking on your desktop and click 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.
Q5: In extended mode, the add-on monitor appears to have a black border around the
desktop.
A: This happens when the resolution used by the add-on monitor is larger than the
resolution used by the primary monitor. To solve this problem, configure the add-on monitor
to use the same resolution as the primary monitor.
