Phone-to-TV picture transmission technology has been around for a long time, but has not been popular due to the complexity of the connection. With the development of the Internet, streaming, available TVs with HDMI and Wi-Fi, image transmission from your phone to TV has become a hot topic. The article contains answers on how to connect your android smartphone or tablet to the TV, as well as recommendations on how to set it up.

Ways to connect a smartphone to the television

Broadcasting from your phone is done wired and wirelessly. Connecting a tablet to the TV is completely similar. There are 4 connection methods:

  • Via HDMI.
  • Using MHL/Slimport.
  • Using USB.
  • Wifi network – DLNA and Miracast.


The connection is made using a suitable cable. One end is plugged into the television and the other end into the phone. This connection ensures fast and smooth data transmission, allowing video streaming in resolutions up to 4K. However, manufacturers have stopped installing the microHDMI connector in android smartphones since 2012, giving preference to wireless technology. Some tablets are still available with this interface.


The technology works in the same way as HDMI, only the microUSB port is used for the connection on the phone side. This eliminates the need for an additional interface, and allows Full HD video to be transmitted at 60fps. However, the number of android smartphones supporting MHL is limited. Also when connecting the adapter, an external 5V power supply is required. If no external power is connected, the battery will quickly run out.


This is a variation of MHL. It also uses a power connector on the phone side and requires the purchase of a suitable adapter for video streaming.


When connected via USB, the smartphone acts as a removable storage device. View the available information via the TV browser.

Wifi – DLNA and Miracast

The DLNA and Miracast protocols, allow you to connect compatible devices via a Wi Fi network and transfer media content. If your TV supports this technology as well as your phone, you just need to connect wirelessly. Then the content on your smartphone screen will be streamed to your TV.

If DLNA and Miracast are not supported but the HDMI port is, the connection is made via media consoles such as Chromecast. Such devices are equipped with Wi-Fi, RAM and flash memory chips. Therefore, data transfer speeds and other features are influenced by the performance of the hardware.

Important: Wired connection methods are gradually being replaced by wireless technology.

Setting up and connecting

How to connect your phone to the TV
via HDMI

1. A compatible cable is required for connection. It is recommended to check the supported protocol version on the manufacturer’s website. Also check the connector type on your device – microHDMI, miniHDMI or HDMI.

2. Next, connect one plug of the cable to the phone, the other to the TV.

3. Go to settings, item picture, to set the preferred transmission resolution.

At this point the connection is complete. The information on the phone screen is automatically displayed on the TV.

With MHL/Slimport

  1. In order for MHL and Slimport to work, a suitable cable or adapter is required in the form of an adapter where one end has a plug for the mobile phone and the other end has a socket for HDMI.
  2. Once connected, the signal source must be specified on the TV as HDMI.
  3. If there are additional settings on the phone, select your preferred settings.

Connecting to a TV using USB

  1. Connection is made using the standard synchronisation cable supplied.
  2. Once connected, the smartphone must be set to USB mass storage mode in the connection settings.
  3. Then select the storage device on the TV to access the files on your phone.

Wifi network – DLNA and Miracast

Most modern televisions support the DLNA protocol. If the protocol is missing but Wi Fi is available, the connection is made via Miracast, which does not require any additional modules in the TV or smartphone.

  1. In the phone settings, you need to activate Wi Fi, then under “Broadcast”, connect to the TV.
  1. In the TV settings, you have to allow detection if the device is not in your smartphone’s connection list.
  2. After pairing, you need to select the phone and allow broadcasting. On LG TVs, you need to open “network”, then Wi Fi Direct, and after switching on, select the device from the list.
  3. The information displayed on the mobile phone will automatically be transmitted to the TV screen.

Important: If your TV does not have a Wi Fi receiver, or if the module is weak and often fails, we recommend using an external receiver or a media set-top box.


A wired connection via HDMI, MHL or Slimport requires little effort to set up, just connect the devices with a cable. Due to the stability and high bandwidth, there are no signal cuts or delays.

A wireless connection requires a one-time setup and takes 2-3 minutes. This method does away with wires, but in low-cost televisions there may be delays when transmitting Full HD video. A similar problem is found in 4K TVs. There are no delays when transmitting Full HD video, but streaming games and other high-definition video is difficult. The problem can be solved by installing a media set-top box with high-performance hardware, as well as a high bandwidth Wi-Fi module.

If you don’t want to stream, but only want to access files on your phone from a TV, then a USB connection is fine.
