The undergrad lab/collaboration room in Malone Hall room 122 has various projectors available for presentation use:

  • A ceiling mounted projector in the main room is connected to the ugrad1 lab machine and has an HDMI connector on top of the ugrad1/ugrad2 table for use with laptops.
  • "Short-throw" projectors in each of the three small breakout rooms have connectors to be used with laptops. The wall closest to each breakout room projector acts as the screen.

The main room projector is controlled from the small Crestron control panel on the ugrad1/ugrad2 collaboration table.

NOTE: When you are done using any of the projectors for your session, please remember to shut them down afterwards. If you were using the main room projector, please also raise the screen.


Using the Main Projector With The ugrad1 Linux Lab Computer

There is a small Crestron control panel on the collaboration table next to ugrad1's monitor.

  • Lower the projector screen.
    • Press the down arrow on the screen control panel, which is on the wall below the clock.
  • Activate the projector.
    • If the projector is off, touch the power icon on the right border of the tabletop control panel to turn it on. The green power LED on the projector will begin blinking.
  • Send ugrad1's video output to the projector.
    • On the control panel, touch the computer icon in the lower lefthand corner (right next to the home icon).
    • Touch the "Linux PC" button.
  • IMPORTANT! When you're done with the projector, please shut it down by pressing the power symbol button on the right border of the Crestron control panel to shut down the projector, then press the up arrow on the screen control panel to raise the screen.

Video Configuration

The ugrad1 lab machine defaults to a side-by-side configuration for the monitor and projector. You can move windows to the projector by dragging them off the left side of the monitor screen.

In some cases, it may be more convenient to have the projector function as a mirror of the monitor. To activate this with the default login environment (Mate Desktop):

  • Go to the "System" menu at the top of the screen.
  • Open the "Preferences" submenu.
  • Open the "Hardware" submenu.
  • Click on the "Displays" entry.
  • In the "Monitor Preferences" window that opens, check the checkbox labeled "Same image in all monitors".
  • Click the "Apply" button.
  • In the "Does the display look OK?" dialog box that comes up, click the "Keep This Configuration" button.

If you make changes to the monitor and projector layout, those changes will be remembered and reapplied every time you log into ugrad1.

Audio Configuration

The audio for ugrad1 can be directed through the room's speaker systems, but it is not set to do that by default. Here's how to set it up:

  • From the "Applications" menu, go to "Sound & Video" and start "PulseAudio Volume Control".
  • Go to the "Configuration" tab.
  • For the "GK106 HDMI Audio Controller" device, select the "Digital Stereo (HDMI 3) Output" profile. It should be the only one that is not "Unplugged".
  • To make all sounds go through the room's speakers:
    • Go to the "Output Devices" tab, find the HDMI controller and click its button with a checkmark in a green circle. (The tooltip for the button is "Set as fallback".
  • If you only want one program to use the room's speakers (e.g. a video playback program):
    • Start that program.
    • Go to the "Playback" tab in the PulseAudio Volume Control program, find your program in the list and change its playback device to the HDMI output.


Using the Main Projector with a Laptop

  • Lower the projector screen.
    • Press the down arrow on the screen control panel, which is on the wall below the clock.
  • Plug your laptop into the HDMI cable on top of the table closest to the printer.
    • If you only have DisplayPort, DVI, or VGA connectors on your laptop, you'll need an adapter.
  • Activate the projector.
    • If the projector is off, touch the power icon on the right border of the tabletop control panel to turn it on. The green power LED on the projector will begin blinking.
  • Send your laptop's video output to the projector.
    • On the control panel, touch the computer icon in the lower lefthand corner (right next to the home icon).
    • Touch the "HDMI" button.
  • At this point you may configure the projector as a second monitor on your laptop. It will probably appear as a monitor named "Crestron Electronics, Inc 36".
  • IMPORTANT! When you're done with the projector, please shut it down by pressing the power symbol button on the right border of the Crestron control panel to shut down the projector, then press the up arrow on the screen control panel to raise the screen.


Using the Breakout Room Projectors

Each breakout room has VGA and HDMI connectors on the wall. There are also audio jacks to be used in conjunction with the VGA connectors.

  • Connect your laptop to either the HDMI or VGA connector.
  • Press the appropriate button on the input selection panel to the left of the connectors.
  • IMPORTANT! When you're done, please press the "PWR OFF" button on the input selection panel to turn off the projector.
