  2. Connect power via USB (use included adapter, not TV USB port)

  2. On Windows PC: Press Win + K → Select your Roku → Mirror screen
  3. On macOS: Control Center → Screen Mirroring → Select Roku

Limitation: Requires a computer to stay on and mirroring. Not ideal for dedicated family displays.

  2. Set to "Never"
  3. Go to Settings → Device Preferences → Screen Saver → When to Start → "Never"

Option 6: Apple TV (4K or HD)​

Apple TV doesn't have a web browser by default. You'll need to use AirPlay mirroring.

  2. On Mac: Control Center → Screen Mirroring → Select Apple TV
  3. On Mac: Open Safari → Navigate to https://app.familycast.app
