  2. Navigate to https://app.brandcast.app
  3. Sign in with your BrandCast account

Limitations of Smart TVs:

  • ⚠️ No auto-start (requires manual launch after power cycle)
  • ⚠️ Browsers may be outdated or limited
  • ⚠️ Performance varies widely by model
  • ⚠️ Recommendation: Use HDMI streaming stick instead for better reliability

Fire TV Stick is one of the best HDMI streaming options for browser-based digital signage.

Step 1: Initial Setup​

  1. Plug Fire TV Stick into HDMI port on TV/monitor
  2. Connect power via USB (use included adapter, not TV USB port)
  3. Follow on-screen setup to connect to WiFi
  4. Sign in with Amazon account (or skip for business use)

Step 2: Install Silk Browser​

  1. Press Home button on Fire TV remote

  6. Press Menu button (three lines) → Settings → Fullscreen Browsing → Enable

Step 4: Auto-Launch on Boot (Advanced)​

Unfortunately, Fire TV doesn't support auto-launching apps on boot without third-party tools. Options:

Option A: Manual Launch (simplest)

  • Open Silk Browser and navigate to BrandCast after each power cycle
  • Best for displays that stay on 24/7

Option B: Kiosk Launcher App (requires sideloading)

  • Install "Fully Kiosk Browser" from APK ($15 license)
  • Configure auto-start to https://app.brandcast.app
  • More complex setup, better reliability

Roku devices have limited browser support. You'll need a workaround.

Step 1: Initial Setup​

  1. Plug Roku into HDMI port on TV/monitor
  2. Connect power and follow on-screen setup
  3. Connect to WiFi

Step 2: Use Screen Mirroring (Workaround)​

Roku doesn't have a built-in browser, so you'll need to mirror from another device:

  1. On Roku: Settings → System → Screen Mirroring → Screen Mirroring Mode → "Always Allow"
  2. On Windows PC: Press Win + K → Select your Roku → Mirror screen
  3. On macOS: Control Center → Screen Mirroring → Select Roku
  4. Open BrandCast on mirroring device

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

Recommendation: Use Fire TV Stick, Chromecast, or dedicated computer instead.

Chromecast with Google TV (NOT the older Chromecast) has a full Android TV interface.

Step 1: Initial Setup​

  1. Plug Chromecast into HDMI port
  2. Connect power via USB
  3. Follow on-screen setup with Google TV remote

Step 4: Disable Sleep​

  1. Go to Settings → Display & Sound → Screen Saver
  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.

Setup with AirPlay Mirroring​

  1. On Apple TV: Settings → AirPlay and HomeKit → AirPlay → "Everyone on Network"
  2. On Mac: Control Center → Screen Mirroring → Select Apple TV
  3. On Mac: Open Safari → Navigate to https://app.brandcast.app

Keyboard/Mouse Not Working After Setup​

Solution:

  • Bluetooth keyboard/mouse may have disconnected - re-pair in device settings
  • Check batteries in wireless keyboard/mouse
  • Use wired USB keyboard/mouse for troubleshooting

Mounting & Installation​

Desktop Computer Setup​

Placement Tips:

  • Mount computer behind display or in nearby cabinet/closet
  • Use long HDMI cable (up to 50 feet for standard HDMI, 100+ feet for active cables)
  • Consider fanless/silent PCs for customer-facing areas
  • Use cable management to hide wires

HDMI Stick Installation​

Best Practices:

  • Use HDMI extender cable (included with most Fire TV Sticks) for better WiFi reception
  • Mount stick on back of TV with adhesive velcro strips
  • Route power cable cleanly along TV edge with cable clips
  • Label which HDMI input is used (e.g., "HDMI 2 - BrandCast")

TV/Monitor Mounting​

Wall Mounting:

  • Use VESA-compatible TV wall mount (size depends on TV)
  • Hire professional installer for TVs > 50 inches
  • Ensure wall can support weight (drywall anchors or studs)

Ceiling Mounting:

  • Use ceiling TV mount with adjustable tilt
  • Common in restaurants, waiting rooms, retail back-of-house
