MH 122 Projectors

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 video connectors on top of the ugrad1/ugrad2 table for use with laptops. The screen for the projector automatically comes down in the front of the room when the projector is activated.

• "Short-throw projectors in each of the 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 may be controlled from either the Crestron panel in the wall to the right of the screen (and to the right of the printer) or from the small Crestron control panel on the ugrad1/ugrad2 collaboration table. These instructions will only cover the latter panel, as it's generally more convenient.

NOTE: When done using the projector for your session, please remember to shut down the projector at the Crestron panel.

Using the Main Projector with the ugrad1 Lab Machine

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

• Activate the Crestron panel.

• • If it's blank, touch anywhere on the screen to turn it on.

• • If it is displaying the message "Welcome to the Computer Science UG Lab" and has a button labeled "START", press the Start button.

• • If it already has a bunch of control buttons visible, go the the next step.

• Press the "PC" button in the "Input Select" group. The screen should lower (if it's not already down) and the projector will turn on (if it's not already on). It will take about 30 seconds before the projector starts displaying an image.

• IMPORTANT! When you're done with the projector, please press the "System Shutdown" button on the Crestron control panel, then press "Yes" when asked if you're sure. This will turn off the projector and 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 right 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

Plug your laptop into the white box on top of the table closest to the printer. The box accepts either VGA or HDMI connections. If you only have DVI or DisplayPort on your laptop, you'll need an adapter. If you use the VGA connector and you want to use the room's speakers, you'll need to connect an audio cable from your laptop's speaker or line out jack to the audio jack on the box.

There is a small Crestron control panel on the collaboration table next to the video input box. If it's blank, touch anywhere on the screen to turn it on. If it is displaying the message "Welcome to the Computer Science UG Lab" and has a button labeled "START", press the Start button. If it already has a bunch of control buttons visible, go the the next step.

Press the "Laptop" button in the "Input Select" group. The screen should lower (if it's not already down) and the projector will turn on (if it's not already on). It will take about 30 seconds before the projector starts displaying an image.

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"'.

When you're done with the projector, please press the "System Shutdown" button on the Crestron control panel, then press "Yes" when asked if you're sure. This will turn off the projector and 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.

When you're done, please press the "PWR OFF" button on the input selection panel to turn off the projector.
