All centrally-scheduled classrooms are equipped with a multimedia projector. These projectors are used in conjunction with an instructor desktop computer to project the computer display onto a screen. Many instructors, particularly those using clickers in their classes, have PowerPoint presentations accompanying their lectures. Instructors can also show web sites, DVDs, and other multimedia presentations to their students as part of their course curricula.

Video projectors are capable of interfacing with a wide variety of devices: desktop computer, laptop computers, VCR/DVD players, document cameras, and more. Any classroom that has a video projector will have, at minimum, an instructor desktop station and a laptop video cable (laptops vary in how they switch between display modes—consult your laptop's documentation to see how to send video out through the projector or contact the Help Desk for assistance).


Classroom projectors are set to be one of two resolutions, based on whether the aspect ratio is standard or widescreen.

  • Standard resolution: 1024 x 768
  • Widescreen resolution: 1280 x 768

When connecting a laptop, you should set the laptop's resolution to match the appropriate resolution for the classroom to get the best quality projection display.

There are two different ways of turning the projector on and off depending on what type of device controller has been installed in that room: AMX panel or EZtrol control panel.

NOTE: EZtrol control panels are gradually being phased out. When they stop working, they are replaced by an AMX control panel.

IMPORTANT: Please DO NOT attempt to recalibrate the projector! The Educational Technology group has already calibrated the projector for optimum performance in the classroom.

If the projector in the classroom you are teaching in experiences issues, please contact the IT Help Desk for assistance.  

Information Technology's classroom technology support group monitors all projectors for performance issues.
