Classroom Technology

Classrooms in Andrews Hall have switched to a new technology setup which requires only a single HDMI connection to supply both audio and video from any device you bring with you.

Preparing to use technology in the classroom

1. Choose a device to bring with you

This could be a laptop, tablet, smartphone, portable document camera, etc. The Department of English has laptops and other equipment available for its instructors to check out for daily use in the classroom. Contact andrewssupport@unl.edu or use our online form to reserve one ahead of time. At least one day of advance notice is recommended.

2. Identify the display port(s) your device has

Every classroom comes equipped with an HDMI cable (Figure I) and an Thunderbolt/MiniDisplayPort adaptor (Figure II). These two connection types can be found on a growing number of devices as the industry moves toward HDMI connections. If you're not sure what kind of display port your device has, consult the Display Ports & Cables Guide.

Troubleshooting Guide

Here are some fixes to common problems that are easy to address.

No picture / Blue screen / Black screen

  1. Make sure both your device and the projector are on and awake
  2. If the screen is black, press "AV Mute" on the projector remote to make sure it's not muted
  3. If the screen is blue with white text along the bottom, make sure all cables are connected securely between your device and the projector
  4. If problem persists after checking these settings, contact andrewssupport@unl.edu.

Desktop wallpaper shows up, but no windows or taskbars appear

You may have 'Extended' selected instead of 'Mirrored.' Check your display settings:

No sound

When connected to the projector, the volume controls on your device may be disabled (e.g. in Mac OS X). Instead, the volume is controlled using the projector remote.

If the projector volume is unmuted and set at a comfortable level, but you still have no sound, check your sound settings:
