2. I cannot play back videos on my external monitor but can play them back on my notebook
computer monitor.
Some notebook computers do not support the Certified Output Protection Protocol (COPP), and you will
not be able to play back the protected videos on the external monitor connected to the dock. The Corel
WinDVD 10 program also has limitations on playing back videos in the Windows XP operating system.
To play back videos on the external monitor, you can connect the external monitor to the VGA connector
on your notebook computer, and extend the display to the external monitor. For more information about
configuring the display settings, see "Working with the dock utility" on page 12.
3. I cannot drag an application window to the other monitor in the Windows XP or Windows Vista
operating system.
In the Windows XP or Windows Vista operating system, you cannot drag a maximized window unless
you reduce the window to a smaller size.
To drag a window from one monitor to the other, do the following:
a. On the window that you want to drag, click the Restore Down button or double-click the title bar to
make the window exit from its maximized status.
b. Drag the title bar of the window to the monitor that you want the window to be displayed.
4. The images on the external monitor flutter.
To solve the problem, check the following:
• Ensure that the external monitor is well connected to the DVI-I video output connector of the dock.
• Check the display resolution setting of the notebook computer and ensure that the resolution is
supported by the dock.
• Check that you do not select Optimize for Video in the Windows Vista or Windows 7 operating
system. If you select it, you might see double image in full screen mode when you right-click the
screen to open the setting menus.
5. The images on the external monitor is not in correct colors.
To solve the problem, do the following:
a. Ensure that the external monitor is well connected to the DVI-I video output connector of the dock.
b. Check the display resolution setting of the computer and ensure that the resolution is supported by
the dock.
6. My computer can play back Web flashes. However, when I drag the window to the external
monitor and maximize the playback window, the playback stops.
To solve the problem, update your Adobe Flash Player to the latest version.
