How to Cast a Chromebook to a Promethean Panel

Overview

You can wirelessly share your Chromebook screen to a Promethean ActivPanel using the Promethean Screen Share Chrome extension. This allows students and teachers to display their screen on the panel without a physical cable connection.

What You Need

A Chromebook connected to the RCS Devices Wi-Fi network.
The Promethean Screen Share Chrome extension installed (see Step 1 below).
The Panel ID displayed on the Promethean panel (visible after launching Screen Share on the panel).

Step 1 — Install the Chrome Extension

Open the Chrome Web Store and search for Promethean Screen Share, or go directly to the extension page.
Click Add to Chrome and confirm when prompted.
The extension icon will appear in your Chrome toolbar.

Step 2 — Start Screen Share on the Panel

On the Promethean ActivPanel, tap the Screen Share app.
A Panel ID (4–6 digit code) will appear on screen — note this number.

Step 3 — Connect from Your Chromebook

Click the Promethean Screen Share extension icon in Chrome.
Enter the Panel ID displayed on the panel.
Enter your name (so the panel can identify who is connecting).
Select the screen or window you want to share.
Click Share. The panel will prompt for confirmation — approve on the panel.
Your Chromebook screen is now mirrored on the Promethean panel.

Troubleshooting

Can't connect? Make sure both the Chromebook and panel are on the same Wi-Fi network (RCS Devices).
Panel ID not working? Restart Screen Share on the panel to generate a fresh ID.
Extension not found? Contact IT — extensions may need to be force-installed via MDM.
