Download the apps

It installs for the current user — no administrator rights — and asks two things at the end: whether to run now, and whether to start ScreenRoll TV when Windows starts. Leave the second on for any screen that must come back after a power cut.

The app opens full screen on a pairing code. Scan the QR with your phone, or type the code into Link TV on the Screens page — the same as Your first screen. From then on it starts straight into playback.

Right-click anywhere on the screen, or press Esc: what the screen is, diagnostics, restarting, unlinking, Settings and closing the app. The tray icon has re-pairing, About and Quit as well.

Use the Windows 7 and 8 build. It runs on Windows 10 and 11 as well, but with an older browser engine, so prefer the ordinary build wherever you can. Choose 32-bit only if the machine is — Settings → System → About says which.

The portable zip needs nothing installed: unzip it anywhere and run ScreenRoll TV.exe. It does not start with Windows by itself — switch that on in the app's Settings.

arm64 for any Mac with Apple silicon (M1 and later), x64 for an Intel Mac. Apple menu → About This Mac says which.

Open the .dmg and drag ScreenRoll TV into Applications.

The app is not yet signed with Apple, so macOS reports a downloaded copy as “damaged”. It is not. In Terminal:

xattr -dr com.apple.quarantine "/Applications/ScreenRoll TV.app"

Then open it normally. Subsequent launches need nothing.

The app registers itself as a login item on first launch. System Settings → General → Login Items shows it, and is where to turn it off.

chmod +x ScreenRoll-TV-*.AppImage
./ScreenRoll-TV-*.AppImage

On first run it writes an autostart entry to ~/.config/autostart, so it comes back with the desktop session.

Use the arm64 build on a Raspberry Pi 4 or 5. Raspberry Pi OS needs one library for an AppImage, once: sudo apt install libfuse2. Without it, start the file with --appimage-extract-and-run.

The player needs a display session — an X or Wayland desktop that logs in on its own. A bare server console cannot draw it.

Apps → type 12345 on the remote → Developer mode On → enter the address of the computer you will install from → restart the television.

The package here is unsigned, and a television installs only a signed one. In Tizen Studio's Certificate Manager create a Samsung certificate once; then, with the television connected in Device Manager:

tizen package -t wgt -s <certificate profile> -- ScreenRoll-TV-1.3.0.wgt
tizen install -n ScreenRoll-TV-1.3.0.wgt -t <television>

Open it from Apps: the same pairing code as everywhere else. The app is a thin shell — it waits for the network, keeps the panel awake and ignores the remote's Back key; the player inside it updates on its own. Hold OK for two seconds for the screen's options.

An LG television installs an app from outside its store only in Developer Mode. Install Developer Mode from the LG Content Store, sign in with a free LG developer account (webostv.developer.lge.com), switch Dev Mode Status on and let the television restart. The mode lasts a limited number of hours and is extended from the same app — enough to try the player, not for a screen nobody will visit.

With LG's command-line tools, on the same network as the television:

npm install -g @webos-tools/cli
ares-setup-device
ares-install --device tv ScreenRoll-TV-1.3.0.ipk
ares-launch --device tv live.screenroll.player

It opens on the pairing code, the same as everywhere else. It is meant for sets from 2018 on (webOS 4 and later). A consumer LG set does not open an app by itself when it is switched on — keep that in mind for a permanent screen. Hold OK for two seconds for the screen's options; with the Magic Remote's pointer showing, hold the wheel.

On a television, a box or a Fire TV stick, install the free Downloader app from the device's store, open it and type screenroll.live/r/apps/latest/tv/android — it fetches the newest build. Or copy the .apk to a USB stick and open it from the device's file manager. On a tablet, download it in the browser.

Android asks the first time and offers the setting. If it does not, find Unknown sources in Settings, under Security & restrictions, and allow the app you install from. On a Fire TV: Settings → My Fire TV → Developer options → Install unknown apps; if Developer options is missing, open About and select the device's name seven times.

On first launch it asks to display over other apps — Android's way of letting an app open by itself after a power cut. Choose Open the setting and switch ScreenRoll TV on. Then restart the device once from its own menu: Android saves the setting a little later, and a power cut in the first minute can lose it. A television with no such setting takes it from a computer:

adb shell appops set live.screenroll.player SYSTEM_ALERT_WINDOW allow
adb shell cmd appops write-settings

It opens on the pairing code: scan the QR, or type the code into Link TV on the Screens page. It runs on Android 7.1 and later. Hold OK for two seconds for the screen's options — a Fire TV remote's menu key opens them too. Back leaves the app, as Google requires of television apps; it starts again by itself at the next power-on.
