Troubleshooting: DPL1 Teacher Staton

DPL1

The teacher station in DPL1 has the ability to project from the desktop, your laptop, a DVD or Blu-ray. All of these options are controlled via the rack to the left of the teacher station. The switcher (red buttons) allows you to switch between different sources easily, simply use the number that corresponds to your source under Input Selector. Unless otherwise indicated below, you need to use the projector remote (white, and located behind the monitor) to first turn on the projector (this may take a minute to warm up) and then to select HDMI as the source.

Audio

For any projection source, you'll need to make sure the audio on the rack is set correctly. To do so, simply look at the topmost panel on the rack and make sure all the volume knobs are set to the middle position (white lines pointing towards 6).

  • The volume is controlled by the silver knob to your left. 
  • Ensure that you are outputting audio through the AJA Device. Click the speaker icon in the top right of your screen and select "AJA Device"
  • If you aren’t seeing this option in the audio settings, check that the AJA hardware in the rack is powered on (the power button should be green if the device is on).

If you can't hear audio in an editing program or when viewing your clips in finder, try playing a YouTube video. If the audio works, that indicates that the problem is with the program or your clips.  Open the NLE's Audio Hardware preferences and select AJA Device.

Desktop

To display the desktop of the teacher station, select input 1 on the switcher.

There are two main ways to display the desktop - as a mirror of the teacher station 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 Preferences and choose the "Displays" option. Under the Arrangement tab, toggle "Mirror Displays" on or off.

If the projector looks pixelated, open the display preferences and select "scaled" then "1920x1080"

Visitor Laptop

To display your laptop's screen, use the HDMI and auxiliary cable hanging underneath the TS desk. Select 4 on the switcher.

To play audio from your laptop, check that the output is set to your headphone jack.

The Blu Ray remote is located in the 810 Annex.

To display a Blu-ray or DVD, power on the Panasonic player and select input 2 on the switcher.

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:

Premiere:

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

Resolve:

  • 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 a stray HDMI cable attached for other purposes, such as attaching a console or visitor laptop. 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.
