Initial Laptop Troubleshooting

Adapter's Preferred Order of Operations

1. If your device requires a display adapter to connect to the provided HDMI cable, follow these steps:

   1. Connect the HDMI cable to the display adapter.
   2. Connect the adapter to your device.
   3. Make sure your device is powered on and awake.
      1. Once connected, your laptop display should appear automatically on the classroom system.

​​​​​Note: If you need a USB‑C–to‑HDMI adapter, USNH has tested and recommends the Anker 6‑in‑1 USB‑C-to-HDMI Multiport Adapter which is available from Amazon and other retailers.

Select your input source and verify display

1. ​ If the system does not start automatically, use the AV touch panel to select the appropriate input source:

   1. HDMI

   2. USB‑C

   3. AirMedia

2. After selecting the input, allow the projector or display time to power on. Your computer’s image should appear on the projection screen; this may take up to 60 seconds.

3. If the image does not display correctly, or if audio is not playing through the room speakers, refer to the troubleshooting sections below for additional guidance.

​​​​​Note: If your classroom utilizes a USB-C connection, please connect your laptop directly using the provided USB‑C cable only. Do not use this connection with an adapter, as the USB‑C cable is designed to work with most laptops and adapters can prevent proper display and connectivity.

2. A display menu will appear on the right side of the screen.

Selecting or Verifying Windows Laptop Audio Settings

If you’re not hearing sound, make sure the correct audio output device is selected.

1. Click the Start button.
2. Select Settings.
3. Click System, then choose Sound.
4. Under Output, select:
   1. Crestron (Intel (R) Display Audio)
      1. Adjust the volume if needed.

Adding a Color Profile in Windows

Mac Laptop Troubleshooting

Screen Mirroring and Extended Mode
Enabling Mirrored Displays will show the same content on both the laptop and projection image.

Apple Control Center  > Screen Mirroring> Mirror or Extend Displays

Selecting or Verifying Mac Laptop Audio Settings

If you do not hear audio through the room speakers, you may need to change your laptop’s sound output setting.

1. Click the Apple () menu in the top‑left corner of your screen and select System Settings.
2. Choose Sound, then click the Output tab.
3. Select the appropriate sound output based on how you are connected:
   • Using an HDMI cable: Select Crestron or Crestron HDMI
   • Using AirMedia (wireless presentation): Select Crestron Audio

Once selected, audio should play through the classroom speakers.

Note: If you see video but do not hear audio (or hear audio but do not see video), reboot your laptop or device. This issue is commonly caused by a temporary driver mismatch and is often resolved after restarting.

1. Click the Apple () menu in the top‑left corner of your screen and select System Settings.
2. Choose Displays.
