Setting Up A Presentation; Using Dual Displays - Lenovo ThinkPad T440 User Manual

Using the mini DisplayPort connector
Your computer has a mini DisplayPort connector, which is a digital display interface for connection to
various external devices, such as Cathode Ray Tube (CRT) monitors, LCD monitors, projectors, or even
high-definition televisions. This compact connector enables a plug-and-play setup and supports adapters
that can plug into DVI, VGA, or High-Definition Multimedia Interface (HDMI™) connectors.
The mini DisplayPort connector of your computer supports audio as well as video streaming.

Setting up a presentation

To display information and make presentations, you can connect a data projector to your computer through
the VGA connector or mini DisplayPort connector on your computer.
Note: It may take several seconds before the projector displays the image. If you do not see your desktop
displayed after 60 seconds, try pressing the F7 key to switch between different display output locations.
Your projector might have one or more audio-input connectors. To project sound, you need to attach
the combo audio connector on your computer to these connectors, using an audio cable (commercially
available).

Using dual displays

This section introduces the Duplicate and Extend desktop functions that enable you to display output on
both the computer display and an external monitor.
Using the Duplicate or Extend desktop function
With the Duplicate desktop function, you can display the same output on both the computer display and

desktop function.
You can use the Duplicate or Extend desktop function without changing any settings. If the function does
not work, refer to the following topic on how to enable the Duplicate or Extend desktop function.
