Browser fullscreen
Open player.dishplay.io, pair the screen, then use the fullscreen button on the player. That button asks the browser to go fullscreen. On a computer you can also use the browser’s own fullscreen command.
On a Smart TV, open the built-in browser (Samsung Internet, LG Browser, or similar) and go to the same address. Some TV browsers only enter fullscreen after a press on the remote, so use the player’s fullscreen button or the browser’s own control.
Leave that tab open. Closing the browser stops the menu. A TV browser is not a locked kiosk: someone with the remote can still leave the page. The Android and Fire TV player below is the path that stays on the menu.
Android and Fire TV
The Dishplay player app is the path that stays on the menu. It hides the system bars and keeps the screen awake. On Fire TV and Android TV it can start again after a reboot.
Full lock — Back and Home staying inside the app — needs the app to be the device owner, or a work-profile owner. Android then runs it in lock task. On a dedicated box you control, with no other user accounts on it, a computer can enroll it with:
adb shell dpm set-device-owner io.dishplay.player/.DeviceAdminReceiver
A device-management system can enroll the same app. Until that enrollment is done, the app still plays fullscreen, and the system buttons can leave it.
Opening settings on a locked player
The Android and Fire TV app keeps an installer panel hidden during playback. On a remote, press Up, Up, Down, Down, Select within 4 seconds. On a touch screen, tap the top-right corner five times within 2 seconds.
The panel can pause auto-launch for 5 minutes, 30 minutes, or until the next reboot, and it can open Wi-Fi, network, or Android settings. There is no PIN. Close the panel, or wait out the pause, and the player returns to the menu.
