4. Troubleshooting Q: Why is the add-on monitor flickering? A: This is usually caused by a low refresh rate. When in "Mirror Mode," increase the refresh rate of the main monitor. This will in turn increase the refresh rate of the add-on monitor, which should stop the flickering. When in "Extended Mode," increase the refresh rate of the add-on monitor. Q: When I play MPEG file by Windows Media Player on the extended monitor, why does the display become abnormal when I switch it to full screen mode? A: If your system is Windows XP SP1, upgrading to SP2 will solve this problem. Q: Why does the video not display properly when in "Full-Screen" mode? 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. • 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." • 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. Q: In "Extended Mode," why does the add-on monitor 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 addon monitor to use the same resolution as the primary monitor. 10 201108084-93-3099.indd 10 8/12/2011 4:40:39 PM
