When running VR training, the person wearing the headset should not be the only one able to see what is happening.
Streaming the headset view to a projector, TV or external monitor allows trainers, instructors and other participants to follow the exercise in real time. This is particularly useful during first aid, fire safety and workplace safety training, where the instructor may want to discuss the participant’s decisions with the wider group.
With Meta Quest headsets, there are two practical ways to do this.
Option 1: Cast through the Meta website
This is the easiest method and does not require additional software.
On your computer, open:
https://horizon.meta.com/casting/
Then log in to the Meta account connected to your headset.
Inside the Meta Quest headset:
Meta Button → Camera → Cast → https://horizon.meta.com/casting/
The headset view should then appear directly inside the browser. Meta recommends having the headset and computer connected to the same Wi-Fi network. Meta Customer Community
From there, simply connect your laptop to the projector or external display using HDMI, USB-C or your normal display connection.
You can then put the browser into full-screen mode so everyone in the room can watch the VR session.
Best for
This method works well for:
- Small training sessions
- Classrooms
- Quick demonstrations
- Meetings
- Events where stable Wi-Fi is available
The main disadvantage is that browser casting depends heavily on the quality of the local network. Poor or congested Wi-Fi can introduce delay or reduce image quality.
Option 2: Meta Quest Developer Hub
For demonstrations, exhibitions or larger training sessions, we generally prefer using Meta Quest Developer Hub (MQDH).
MQDH is Meta’s official desktop application for managing Quest headsets and includes built-in headset casting. It is available for Windows and macOS. Meta for Developers
Once the headset is connected:
Meta Quest Developer Hub → Device Manager → Cast
A live view of the headset will open directly on the computer. Meta for Developers
The laptop can then be connected to your projector or external screen.
MQDH also provides additional options such as different aspect ratios, screenshots and recording. Meta’s newer casting system supports formats including widescreen views, which can be particularly useful when presenting VR on a large screen. Meta for Developers
What about ADB?
You may sometimes hear this described as ADB casting.
ADB, or Android Debug Bridge, is the underlying communication system used to connect a computer to Android-based devices such as Meta Quest. Meta officially supports connecting Quest devices using ADB through either USB or Wi-Fi. Meta for Developers
However, for most trainers there is no reason to work directly with ADB commands.
Meta Quest Developer Hub is much easier.
It provides a graphical interface while handling much of the device communication in the background.
For an important presentation, you can also connect the Quest to the computer using a USB-C data cable, reducing your dependence on the venue’s Wi-Fi.
Which method should you use?
For a quick demonstration:
Quest → Wi-Fi → Meta Casting Website → Laptop → Projector
For professional training or events:
Quest → USB/Wi-Fi → Meta Quest Developer Hub → Laptop → Projector
At 4HELP VR, displaying the VR experience on an external screen is particularly useful during group training. While one participant completes the scenario inside the headset, the instructor and the rest of the group can observe the decisions being made, discuss mistakes and prepare for their own turn.
VR may be experienced by one person at a time — but the training does not have to be.
One headset. One participant. An entire room learning together.
