Android TV set-top boxes turn an ordinary TV into a smart multimedia center with access to streaming, games and applications. But many users encounter difficulties already at the connection stage: the sound does not work, there is no picture, or the set-top box does not see the network. This article will help you avoid common mistakes and set up your device correctly - from choosing a cable to optimizing performance.

We will look at all connection methods (including rare scenarios for older TVs without HDMI), adjust the screen resolution for the perfect picture, learn how to control the set-top box from your phone and fix freezing problems. And at the end - answers to frequently asked questions about compatibility with 4K, Dolby Vision and game controllers.

Selecting and preparing equipment

Before connecting, check the compatibility of your set-top box and TV. Modern models (for example, NVIDIA Shield, Xiaomi Mi Box or Mecool KM2) require HDMI port version 2.0 4K HDR output. If your TV was released before 2015, you may need an adapter or limit the resolution to 1080p.

Minimum set for connection:

  • 📺 TV with HDMI (or adapter for AV/Component if HDMI missing)
  • 📱 Android TV set-top box with power supply
  • 🔌 HDMI cable (preferably High Speed for 4K)
  • 📶 Wi-Fi router (or Ethernet cable for a wired connection)
  • 🎮 Remote control (usually included, but you can use a smartphone)

Pay attention to resolution of your TV screen: if it is lower 1080p, you will have to manually set the supported mode in the set-top box settings, otherwise the image will be cropped or blurred. To check the resolution, look at the TV menu: Settings → General → TV information.

Methods of connecting the set-top box to the TV

The main method is through HDMI cable, but there are alternatives for older TVs. Let's consider all the options:

Connection method Required equipment Max. resolution Features
HDMI → HDMI HDMI 2.0/2.1 cable 4K@60Hz, 8K@30Hz Best quality, HDR support
HDMI → AV (composite) HDMI-to-AV adapter 480p For very old TVs, audio delays are possible
HDMI → SCART HDMI-to-SCART adapter 576p Rarely found, requires manual configuration
Wireless (Miracast) Miracast support on TV 1080p@30Hz Depends on the stability of Wi-Fi

For connection via HDMI:

  1. Unplug the TV and set-top box.
  2. Connect the HDMI cable to the port HDMI IN on the TV and HDMI OUT on the set-top box.
  3. Turn on the TV and switch to the desired HDMI input (button Source or Input on the remote control).
  4. Connect power to the set-top box - it should start automatically.

If the image does not appear:

  • 🔄 Try another HDMI port on the TV (some ports support only 1080p).
  • 🔌 Check the cable - budget cables may not transmit 4K.
  • 📺 On some TVs (for example, Samsung QLED) you need to enable the HDMI-UHD Color mode in the port settings.

☑️ Check before turning on for the first time
