• Lenovo Presentation Director
  • When used with some systems, the display utility customized for use with the USB 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.
• DVD Playback
  • Lenovo's latest ThinkPad notebooks, including ThinkPad X300, support digital rights management and, by design, do not pass protective content material through an open USB port. Consequently, some preinstalled applications like WinDVD5 or Windows Media Player cannot play protected DVD content on an external monitor attached to the USB Port Replicator. This is dependent on your computer system and applications used to play video. If you encounter any problems when playing a DVD on an external monitor attached to a USB Port Replicator, simply close the playback window and play the DVD on your system LCD screen or on the external monitor attached to the ThinkPad VGA port.
• Screen flashes
  • For maximum convenience, the USB Port Replicator can be hot docked or undocked from your notebook at any time. You are not required to shut down, suspend, or hibernate to perform these actions. You may, however, see several screen flashes whenever you boot up your system or resume from suspend or hibernate. This is normal operating system behavior that occurs as the port replicator initializes.
