5 High-Definition Multimedia Interface (HDMI) connector
The HDMI connector is a digital audio and video interface. It enables you to connect your computer to a
compatible digital audio device or video monitor, such as an HDTV.
Note: The HDMI connector on your computer supports the HDMI 2.0 standard by default. If you connect an
external display to your computer through the HDMI connector with an HDMI 1.4 cable which is longer than
10 meters, the external display might not work. In this case, do one of the following:
• Use a qualified HDMI 2.0 cable instead of an HDMI 1.4 cable.
• Change the HDMI standard of the HDMI connector from 2.0 to 1.4. To change the HDMI standard, start
the ThinkPad Setup program (see "Configuring ThinkPad Setup" on page 59), and then configure HDMI
Mode Select in "Config menu" on page 61.
6 Audio connector
You can connect headphones or a headset with a 3.5-mm (0.14-inch), 4-pole plug to the audio connector to
listen to the sound from the computer.
If you are using a headset with a function switch, do not press this switch while using the headset. If you
press the switch, the headset microphone is disabled, and the integrated microphones on the computer are
enabled instead.
Note: The audio connector does not support a conventional microphone. For more information, see "Using
audio features" on page 29.
