On a TV: open this page on whatever drives the screen — a laptop on HDMI, or a cast browser tab — and it follows whichever device you tap. Simplest alternative: mirror your phone with AirPlay or Chromecast, and set Screen to Landscape above so it fills the TV.

Screen stays awake while the app is open
