1. What cables and adapters will be needed for connection

The first step is to check the compatibility of the equipment. Most modern Androiddevices support connection via USB-C or Micro-USB, but additional adapters or cables will be required to output the image to the TV through the receiver. Here are the main options:

  • 🔌 USB-C → HDMI: Adapter for smartphones with support DisplayPort Alt Mode (most flagships after 2018). Allows you to transmit video and audio over one cable.
  • 🔄 MHL cable: An outdated but still relevant standard for devices before 2016 (for example, Samsung Galaxy S5 or Sony Xperia Z3). Requires support MHL from the TV.
  • 📱 USB-OTG + HDMI: Combination of cable OTG and adapter HDMI for devices without direct video support via USB. Does not work on all models.
  • ⚡ Slimport: Alternative MHL, used in some devices LG and Google Nexus. Requires a special adapter.

Before purchasing an adapter, check the specifications of your smartphone on the manufacturer’s official website. For example, Samsung Galaxy S22 supports DisplayPort Alt Mode, and Xiaomi Redmi Note 10 only USB-OTG without video output. If your receiver does not have HDMI input, you will need an additional converter (for example, HDMI → AV).

⚠️ Attention: Some budget smartphones (for example, models Tecno or Infinix) block video output via USB due to manufacturer restrictions. In this In this case, only a wireless connection remains.
Connection type Supported devices Max resolution Do you need power
USB-C → HDMI (Alt Mode) Samsung S20+, Google Pixel 6, OnePlus 9 4K@60Hz No
MHL Samsung Note 4, Sony Xperia Z5 1080p@30Hz Yes (5V)
Slimport LG G4, Google Nexus 5X 4K@30Hz Yes (5V)

⚠️ Attention: On some firmware (for example, ColorOS from Oppo/Realme) option DisplayPort Alt Mode can be disabled by default. To activate it, you will need root access or a special application like USB Debugging Enabler.

3. USB receiver: step-by-step guide

Now let's move on to the connection process itself. Let's consider the two most common scenarios: via HDMI receiver (for example, a set-top box from a provider) and directly to a TV with USB port.

Scenario 1: Connecting to an HDMI receiver (set-top box)

If your receiver has USB portbut does not support MHL or DisplayPort, you can try using it as an intermediate device for transmitting content:

  1. Connect your smartphone to the receiver via USB-OTG cable.
  2. On the receiver, select the signal source USB or Multimedia (depending on the model).
  3. On your smartphone in the notification shade, select the mode File transfer (MTP).
  4. Launch an application on the TV for viewing media files (for example, Photo/Video or Media player).

Important: in this mode you can only view files stored on your smartphone (photos, videos, music), but not duplicate the screen or launch applications.

Scenario 2: Direct connection to a TV with USB

If your TV supports USB-host (for example, models Samsung TU7000 or LG UK6200), you can connect your smartphone directly:

  1. Connect your smartphone and TV cable USB-C → USB-A (or Micro-USB → USB-A).
  2. On the TV remote control, select the signal source USB.
  3. On your smartphone, allow access to data (when prompted).
  4. Use the TV’s built-in media player to view files.

To mirror the screen (mirroring) via USB, you will need support DisplayPort Alt Mode or MHL. In this case, the algorithm is different:

  • 🔗 Connect your smartphone to the TV via USB-C → HDMI adapter.
  • 📺 On the TV, select the source HDMI (port to which the adapter is connected).
  • 📱 On the smartphone in the screen settings, activate the option Wireless/HDMI (the name may vary).
💡

If the TV does not see the smartphone, try using another USB port (some models have ports only for service functions) or reboot both devices.

4. problems

Even with proper connection, errors may occur. Here are the most common ones and ways to eliminate them:

Problem Possible cause Solution
