Using the LCD Projection System

The West Wing Collaborative Cluster is home to a 46 inch ceiling mounted LCD on a rotating stand.  The LCD is mounted within a traditional grouping of 12 Linux workstations. There are 5 desktop (CPU) and 3 laptop connections setup to project to the LCD.  The LCD is controlled by 2 panels: Panel 1 is located at the head of the workstation area near CPU 1 and CPU 2; Panel 2 is located near CPU 3, CPU 4 and CPU 5 at the other end of the workstation area near the LCD.  (The CPU numbers are labeled at the top left corner of the monitors.)

Which Panel Controls the LCD Display

The panel used to power on the LCD projection system is considered the “master” panel. Only the master panel can initiate the share control feature. 

How do I know if the panel I’m using is the master panel? 

The following indicator lights are illuminated at the master panel:

  • On button
  • Share Ctrl button (on and steady)
  • 2 vertical bar lights at the lower right corner of the panel
Note: The On button is also illuminated at the alternate panel. However, the 2 vertical lights in the lower right corner of the panel and the Share Ctrl light are NOT illuminated.

If I'm not at the master panel, how do I use the LCD display?

You will not be able to project to the LCD unless the share control feature is activated from the master panel.  This is indicated when the Share Ctrl light is illuminated and blinking.  If noone is using the master panel, turn both panels off and turn the system on from the panel you wish to work from.

Project from Desktop (CPU)

  • Use Panel 1 to project from desktop machines labeled CPU 1 and 2.
  • Use Panel 2 to project from desktop machines labeled CPU 3, 4 or 5.
Remember: If you are not at the master panel, the share control feature must be activated from the master panel for you to use the LCD display.  Share control is active when the Share Ctrl light is blinking. 
  1. Press the CPU button that corresponds to the computer you are using (e.g., CPU1 or 2 from Panel 1 or CPU 3, 4, or 5 from Panel 2).
  2. Your computer display will be projected on the LCD.  
  3. Please press the Off button when you are finished with the LCD projector.

Project from Laptop

  • Use Panel 1 to project from laptops connected to the Laptop 1 or Laptop 2 cables.
    Note: The Laptop 1 cable is located within the Panel 1 control box. The Laptop 2 cable is located at the mobile table just below the LCD. 
  • Use Panel 2 to project from a laptop connected to the Laptop 3 cable (located within the Panel 2 control box).
Remember: If you are not at the master panel, the share control feature must be activated from the master panel for you to use the LCD display.  Share control is active when the Share Ctrl light is blinking.
  1. Connect your laptop to the Laptop 1, 2 or 3 cable.
  2. Press the laptop button that corresponds to the laptop cable to which you are connected (e.g., Laptop 1, 2 or 3).
  3. Your laptop display will be projected on the LCD.
  4. Please press the Off button when you are finished with the LCD projector.

Share Control of LCD 

From the master panel, you may activate the share control feature to allow connections at the alternate control panel access to the LCD display.

Remember: The master panel is the panel that powered on the system.  Two vertical lights in the bottom right corner of the panel will be illuminated. 

  1. Press Share Ctrl from the master panel.  The red light on the Share Ctrl buttons at both Panel 1 and Panel 2 will blink to indicate that “shared control” is activate.
  2. Press the CPU or Laptop buttons at Panel 1 or Panel 2 to toggle the LCD display between any of the connections (i.e., CPU 1, 2, 3, 4, 5 or Laptop 1, 2, 3).
  3. Please press the Off button when you are finished with the LCD projector.
