Instructor station connections

All rooms have a VGA connection. We are continually updating the classroom equipment and adding new inputs, such as USB-C. While we attempt to provide the best set of connections possible, you are responsible for providing an adapter to make sure your device can connect to the system.

Read below for more information on each type.

Using a VGA connection

General purpose classrooms have VGA connections as their standard computer-video interface.

Be sure to also connect the audio cable if you need to present audio with your visuals.

Using HDMI, Mini DisplayPort, or USB-C

Connect the cable in the tech pocket at the instructor station to your device.

  • If you use the Mini DisplayPort adapter, be sure to select HDMI as your presentation source.

  • The audio cable will only work if VGA is selected as the presentation source.

  • If you don’t hear audio, you may need to make a change in your device’s settings to send audio to the correct output.

Availability in OCM classrooms

There are several ways to determine if the classroom in which you are scheduled has your preferred connection:

  • Preview the room before your next class or event. The touchscreen interface will have a different button for each presentation source type.

  • Use Room Search to view the equipment available in your room. Currently, Connection - HDMI and Connection - USB-C, are both listed as features of rooms that have those connections.

  • Email us at classrm@umn.edu.

Which connection should I use?

While VGA is widely available, digital connections:

  • Have better overall display quality that is especially useful for high-resolution images or video.

  • Only require a single cable for transmitting both audio and video. (Make sure your device is sending audio over that connection.)

  • Require little-to-no user adjustments after connection as devices that use HDMI, Mini DisplayPort, or USB-C typically sense other devices and automatically adjust to the proper resolution.
