Chromecast / Chrome
Open Display Mode in Chrome, choose the browser menu, then Cast and select the TV or display. Choose Cast tab or Cast screen depending on your device.
Cast / TV classroom hub
Show lessons full-screen on a TV, projector, tablet or second display.
Use the browser’s Cast Tab, AirPlay, Miracast, HDMI or a second window. The lesson content stays offline and local-first; casting support depends on the device, browser and display.
Same-browser controller
Control the display tab or cast tab
Open Display Mode in another tab/window, then use these controls to send lesson and slide changes. This works best when the display tab and controller are in the same browser/device.
Controller ready. Open Display Mode first for best results.
Device options
How to show it on a TV or other device
AirPlay / Apple TV
Open Display Mode, then use Screen Mirroring or AirPlay from the device control centre. Put the lesson into full screen for a clean classroom view.
Miracast / Windows
Use Windows display projection or wireless display, then open Display Mode in the browser and select landscape or portrait layout.
HDMI / Projector
Connect the device to the TV or projector, open Display Mode, press Full screen, and use keyboard arrows or on-screen controls.
Important limitation: Web apps cannot force every TV to cast directly. This pack adds a cast-friendly display mode, a same-browser controller, Discuss Mode autoplay/read-aloud and a browser Presentation API attempt where supported. Real casting still depends on the teacher’s device, browser, TV and network.
