Setting up a presentation

To make presentations, you can attach a projector to your computer through the HDMI port on your computer.

Note: If the projector connector is not compatible to the HDMI port on your computer, you can purchase a converter cable on http://www.lenovo.com/accessories/services/index.html.

It might take several seconds before the projector displays the image. If you do not see your desktop displayed after 60 seconds, press F7 to switch between different display output locations.

Your projector might have one or more audio-input connectors. To project sound, you will need to attach the combo audio jack on your computer to these connectors, using an audio cable (commercially available).

Using the AMD Switchable Graphics feature

Some ThinkPad notebook computers support the AMD Switchable Graphics feature.

To achieve the best balance between the computer performance and a long battery life, depending on the graphics quality demand of the running program and the settings of the power plan that you use, the AMD Switchable Graphics feature automatically switches between High Performance Graphics and Energy Saving Graphics, with no need to restart your computer, close programs, or intervene manually.
