Troubleshooting: DPL Teacher Staton

DPL (Ansin 809)

The teacher station in DPL has the ability to project and play audio from the desktop computer, your laptop, a DVD, or Blu-ray. All of these options are controlled using the rack on the desk to the right of the teacher station. The switcher (red buttons) allows you to switch between different sources easily; simply use the number that corresponds to your input.

Input 1: Teacher Station Computer
Input 2: Blu Ray Player
Input 4: Visitor HDMI (cable hanging under the desk)




Turn on the projector using the remote (this may take a minute to warm up).

The projector itself should always be set to "HDMI 1" - we will always use the switcher on the rack to toggle our source.

To temporarily mute the projector, use the “mute” button on the switcher or the “shutter” button on the projector remote.


The volume is controlled by the silver knob to the right of your monitor.

The correct audio setting for the speakers is “VS-116DT”


If you are playing audio from an NLE like Premiere, be sure that the audio hardware preferences within the NLE match the Mac’s system settings.

You should never need to adjust the knobs on the rack itself, but it is possible that somebody else may have. Check that each of these knobs are pointing towards 6.




To display the desktop of the teacher station, change the Input Selector on the rack to 1.


There are two main ways to display the desktop - as a mirror of the teacher station screen, or as a second monitor. Mirroring should be on by default. If you'd like to change this, open the system settings.

Next to "Use as" open the drop down menu and select "Extended display" to stop mirroring. If you'd like to return to mirroring, open the same drop down and select "mirror for Studio Display"

Visitor Laptop

To display your laptop's screen, use the HDMI and auxiliary cable under the Teacher Station desk.

If your laptop does not have an HDMI output, adapters are available in the 810 annex. 

Once you are connected, change the Input Selector on the rack to 4, and your screen should display.


There are two main ways to display the desktop - as a mirror of the laptop screen, or as a second monitor. Which you choose depends on how you like to project your screen, but note that mirroring can distort both displays. To toggle between these two, open System Settings and choose the "Displays" option. Here, you can toggle between mirrored or extended displays.

To play audio from your laptop, make sure the auxiliary cable is plugged into your device and the output is set correctly on your machine.


To display a Blu-ray or DVD, power on the Panasonic player in the rack. Change the Input Selector on the rack to 2. The Blu-ray player should now appear on the projector. The remote control for the player can be found in the 810 Annex.


Using the OLED Monitor as a Broadcast Monitor

The OLED monitor is usually set up as a broadcast monitor, meaning it displays the timeline of an NLE (Premiere, Resolve, Final Cut, etc.) from the teacher station at full screen with color accuracy. It is not set up to act as a third desktop.

Power on the monitor by pressing the power button on the back left corner of the television, or checkout the remote from the lab assistants in 810. The correct input is HDMI 1.

If the timeline doesn’t display automatically, open the preferences for your NLE:


  • Open Preferences/Playback
  • Check “Blackmagic Playback”
  • If this is already checked, click “setup” and select “scale down”


  • Open Preferences, then Video and Audio I/O
  • Under “For capture and playback” select “Blackmagic”

After Effects:

  • Open Preferences/Video Preview
  • Check Enable Mercury Transmit
  • Check Blackmagic Playback
  • If this already checked, click “setup” and select “scale down”


Using the OLED Monitor for other purposes

The monitor has an open HDMI input for other purposes, such as attaching a console or visitor laptop.

Check out an HDMI cable from the lab assistants in 810 and use that top plug your device into the open port on the rack labeled "OLED HDMI 3"

On the TV, the correct input for this cable is HDMI2. You can change this by checking out the remote from the lab assistants in room 810.

In this case, the monitor will act as a traditional display rather than a broadcast monitor.

Please be sure to turn off the monitor when you have finished. You will know it is off when the red light on the bottom of the frame is glowing.
