How to Fix Chromecast and Fire TV Setups for Your Pourwall Tap List

Running Pourwall on a TV should be simple: connect a Chromecast or Fire TV Stick, pull up your tap list, and you are done. When the menu disconnects or the list won't return after turning on the TV, the most common cause is how the streaming stick is powered or set up. Below is a direct checklist for both Chromecast and Fire TV configurations, strictly focused on reliable display of your Pourwall tap list. All recommendations are accurate as of June 2026.

What causes Chromecast and Fire TV to drop the Pourwall tap list?

The main issue is power loss: if your Chromecast or Fire TV Stick gets power from the TV's USB port, the device completely shuts down every time the TV turns off. This breaks its Wi-Fi connection and interrupts casting or mirroring. HDMI-CEC settings (letting HDMI devices control each other) can also affect reliability, depending on your TV and setup. Source device settings like battery optimization and choice of casting vs mirroring make a difference as well.

Chromecast/TV configuration for stable Pourwall menus

Check Chromecast power source

  • Action: Plug the Chromecast into a wall outlet using the original adapter. Never use the TV's USB port.
  • Reason: When connected to the TV's USB, Chromecast goes fully offline when the TV powers off. Using a wall outlet keeps it online and connected to Wi-Fi, so it is ready as soon as the TV is turned on.

Enable HDMI-CEC (Consumer Electronics Control) if available

  • Action: In your TV’s settings, find HDMI-CEC. This can be called Anynet+ (Samsung), BRAVIA Sync (Sony), SimpLink (LG), EasyLink (Philips), or VIERA Link (Panasonic). Turn it on.
  • Reason: HDMI-CEC allows devices to signal each other. It can help the Chromecast keep a sense of connection even if the TV is turned off, and it should switch your TV to the Chromecast input automatically when you start casting. On some TVs, it also improves the connection handshake after power cycles.

Source device (App/Phone) configuration for Chromecast reliability

Disable power and battery optimizations

  • Action: On your phone or tablet, go into battery settings. Exclude both the app you are using to show the tap menu and the Google Home app from power/battery optimization or "put to sleep" features.
  • Reason: Many phones close background apps to save battery. Doing so will kill any screen mirroring or casting session, especially if you lock your phone or it sleeps.

Prefer casting over full device screen mirroring

  • Action: If your menu app supports the Cast button (the rectangle with a Wi-Fi bar), use it. Avoid full device screen mirroring through the Google Home app if you can.

  • Reason: In-app casting lets Chromecast pull data directly from the web, staying online even if your phone dies or leaves. Full device mirroring is less stable—it stops the instant your device disconnects or idles.

  • If your tap menu app only supports screen mirroring, disabling battery optimization is the first step, but recognize that this method is inherently more prone to disconnects.

Why does screen mirroring stop after TV power cycles?

Screen mirroring always drops when HDMI sticks like Chromecast or Fire TV lose power or their HDMI connection is cut, which happens when you turn off the TV or change inputs. This is a limitation of how HDMI signaling and wireless mirroring protocols work. Powering from a wall outlet and correct HDMI-CEC settings make reconnection faster, but expect to re-initiate mirroring after every TV power-off if you cannot use native casting.

Fire TV configuration for stable Pourwall menus

Power your Fire TV Stick from a wall outlet

  • Action: Plug the Fire TV Stick into a wall outlet or power strip using the original power adapter and cable. Do not use the TV's USB port.
  • Reason: The Fire TV Stick shuts down completely when powered from a TV's USB port, breaking its connection. Wall power keeps it online so it remains connected to Wi-Fi and ready for display.

Fire TV display and mirroring settings

  • Action: To begin mirroring, press and hold the Home button on the Fire TV remote, then select Mirroring. You must be in this mode for the Fire TV Stick to accept a mirroring connection (the device will exit this mode after a period of inactivity).
  • Action: In Fire TV settings (Settings → Display & Sounds → Display), experiment with setting Video Resolution to 1080p instead of Auto or 4K if you experience errors.
  • Reason: Locking the resolution can help avoid handshake issues between the Fire TV Stick and older TVs, often making mirroring connections more stable.

Adjust TV HDMI-CEC settings

  • Action: In your TV’s settings menu, find the HDMI-CEC option (it may be called Anynet+, BRAVIA Sync, SimpLink, or similar). Try both ON and OFF states.
  • Reason: Some TVs keep the Fire TV Stick active longer with CEC ON and re-initiate the HDMI connection when the TV powers on. For other setups, the opposite may be true. Each TV model behaves differently—test both options.

Source device (App/Phone) configuration for Fire TV reliability

Disable battery optimizations for all tap menu and mirroring apps

  • Action: Remove all battery or power saver restrictions for both the tap menu app and any system apps that manage mirroring from your phone or tablet.
  • Reason: If the phone sleeps or these apps are closed, the mirroring session disconnects instantly.

Prefer native Fire TV app if your menu supports it

  • Action: If your tap menu provider offers a native Fire TV app, install and use that instead of mirroring.
  • Reason: Running natively on Fire TV removes the dependency on external screen mirroring, making the display more resilient to device or network hiccups.

Keep device operating systems updated

  • Action: Make sure your phone or tablet is running the latest OS version available.
  • Reason: Updates often include stability and security fixes for wireless display standards like Miracast or Airplay, which the Fire TV uses for screen mirroring.

What should you do next?

If your Pourwall tap list display disconnects or fails to return after power cycles, first check that Chromecast or Fire TV Stick is powered from a wall outlet using the original adapter. Adjust HDMI-CEC settings on your TV and experiment with both enabled and disabled states. Make sure your source device and any casting or mirroring apps are excluded from battery optimization. Use native casting or a Fire TV app if it is supported. If you use screen mirroring by necessity, be ready to re-initiate it after every TV power-off or input change.
