Straight answers before you install.

Samsung Tizen TVs, including The Frame, are integrated in this beta. LG webOS, Sony BRAVIA with IP Control, and Vizio SmartCast are experimental and need hardware testers. Roku, generic Google/Android TV, and Fire TV are not supported in this beta.

Compatibility depends on the model, firmware, and TV settings. A brand name alone does not guarantee support.

Yes. The computer must be powered on, signed in, connected to your home network, and running the app during quiet hours. Optional settings can prevent normal idle sleep and request a native wake timer, but they depend on your computer. Native GUI and hardware sleep/wake testing remain unverified for these testing packages. Closing a laptop lid or choosing Sleep may still suspend it.

During quiet hours the app checks enabled TVs approximately every 15 seconds. If a compatible TV reports that it is on, the app sends an off command. Checks continue throughout the night. Exact timing depends on your network and how the TV responds.

No. When quiet hours end, checking stops. The app never automatically turns a TV on.

That is what the required off test is for. After pairing, the app asks you to confirm that the screen goes fully dark and Art Mode stops too. The original prototype did this on a 2021 The Frame, but models and firmware differ, so confirm it on your own TV.

No. TV control happens locally on your home network. The app needs no account, subscription, vendor-cloud login, or Samsung Windows software.

An unreachable TV stays unconfirmed and is checked again on the next pass. The app needs a fresh on response before it sends an off command. Activity history shows what it saw.

Yes. This beta is a household convenience tool and is not tamper-resistant. Anyone with access to the computer can pause quiet hours or quit the app. Closing the window leaves it running in the system tray; quitting stops checks.

The current Windows portable beta is unsigned, so Windows SmartScreen cannot show a verified publisher. Download only from tvnightguard.com, and compare the file’s SHA-256 checksum with the one on the downloads page. Never disable your antivirus to run it. If your security software blocks the file, tell us instead.

Beta.4 is available as Windows x64 portable, Linux x64 AppImage, and Linux amd64 Debian ZIPs. The Windows installer is pending. Mac DMG builds are configured but have not been built on a Mac runner; signing and notarization are not configured. No Mac release date has been announced.

These are unsigned testing packages, not hardware-validated releases. Native GUI and sleep/wake hardware testing remain unverified on Windows and Linux. Quiet-hours scheduling, startup at sign-in, and native wake requests are included in code.

Wake requests require compatible hardware and OS settings; Mac and Linux setup requests administrator approval. Linux needs systemd and a supported hardware wake clock. The computer must remain signed in with the app running. Wake requests do not unlock the computer or power on a shut-down machine.

The public beta is free during the testing period. Future pricing has not been announced; participation does not promise lifetime free access.

Beta.4 expires on October 28, 2026 at 08:40:28.369 UTC (2026-10-28T08:40:28.369Z). That is 30 days after its build time—not 30 days after installation. The app shows its expiry date. Install a newer testing build to continue after it expires.

After expiry, TV control stops. You can still inspect your settings, export diagnostics, remove saved TVs, and turn off startup and wake options. Expiry does not delete your data. Disable any saved wake task in Settings before uninstalling; the app will not request administrator approval automatically when it expires.

Use the feedback form on this site. Include your TV brand, model, firmware if you know it, and what happened. If it helps, export the anonymous diagnostic file from the app and email it to support@tvnightguard.com. Never send pairing tokens, pre-shared keys, or your application-data folder.

Before uninstalling or moving the app, disable the guard and turn off startup and wake options in Settings, then save. Remove saved TVs first if you want to delete their credentials. Quit from the tray. For Windows portable, delete the entire extracted runtime folder; for Linux AppImage, delete the AppImage; for Debian, uninstall with your package manager. Local settings are retained unless you also remove the app data folder. See the versioned release privacy notice for data locations. Your TVs are not changed.
