The latest ThinkPad® notebook computers, including ThinkPad X300, support Windows Media® Digital Rights Management (DRM), and do not support the protected DVD content passing through a USB port. Therefore, when an external monitor is attached to the Lenovo Enhanced USB Port Replicator, some pre-installed applications such as WinDVD 5.0 and Windows Media Player cannot play the protected DVD content. If you encounter any problems when playing a DVD on the external monitor attached to the Lenovo Enhanced USB Port Replicator, close the playback window, and play the DVD directly on the liquid crystal display (LCD) or the external monitor attached to the Video Graphics Array (VGA) port on your notebook computer.
For maximum convenience, the Lenovo Enhanced USB Port Replicator can be easily hot docked or undocked from your notebook computer at any time. The screen might flash several times when the notebook computer boots up or resumes from suspension or hibernation. This is normal behavior in the Microsoft® Windows Vista® operating system that occurs when the Lenovo USB Port Replicator initializes.
When used with some systems, the display utility customized for use with the port replicator will override Lenovo Presentation Director when the user selects Fn + F7. A popup box will appear directing the user to go to that specialized utility to make display selections. On other systems, Presentation Director will function normally.
With a Thinkpad X300 notebook system, while in Windows XP, the external monitor cannot be set to primary. The LCD must remain primary and the external monitor set to secondary. While under Windows Vista, the external monitor can be set as primary and the LCD set to secondary. This situation is currently under investigation.
When your USB Port Replicator does not operate as expected, check these items first to try and correct the problem.
The Power Indicator of the USB Port Replicator does not grow amber or green. Ensure that the AC adapter provided is plugged into the USB Port Replicator and into a working electrical outlet. Do not use any AC adapters other than the one supplied with the USB Port Replicator.

When you are in the Extended mode and playing back video clips, only one video clip can be seen. When in the Extended mode, only one video play back application can be used at a time. If multiple video clips are played back, only one video clip is visible to the user. This also applies to Web pages with embedded video clips. To view these Web pages, move one page to the notebook computer screen and the other to the external monitor.

This action fixes most of the issues related to the quality of the video on the external monitor. Refer to your notebook computer user's guide for instructions on the auto-adjust procedure.
External monitor flickering
