Usage

1. Turn on your projector and set it to the HDMI input.
2. The Chromecast homescreen will appear.
   1. The Chromecast is usually named by the room where it is located.
3. On your computer, open Google Chrome browser, open the 3-dot menu, hover over “Save and share” and select “Cast…”.
4. At the bottom of the small window that appears, click on “Sources ▼” and choose either “Cast tab” or “Cast screen”.
   1. “Cast tab” will cast only the current tab, even if you switch to a new tab or window.
   2. “Cast screen” will cast everything on the screen, including when you change windows, tabs, and even programs.
5. On the list of Chromecast devices, scroll down until you find the one labelled with your room number/letter, and click on it.
   1. If you chose “Cast tab”, the cast session should begin immediately with your tab appearing on the projection.
   2. If you chose “Cast screen”, you will need to select the display in the small window that pops up first, then click on “Share” to begin the cast session.

macOS Screen Recording Permissions

NOTE:

There is a known issue on macOS devices running versions 14(Sonoma) & 15(Sequoia) which causes Google Chrome’s ‘Cast screen’ feature to not function. ‘Cast tab’ still works. A possible fix is to disable “Use graphics acceleration when available” in the System tab of Chrome Settings.

4. Scroll to and select “Screen Recording” in the list on the left
