Viewing information on a large screen is always more convenient than on a smartphone’s display. Therefore, many users often connect the phone to a TV or large monitor. In the article, we will consider the main connection methods, as well as the most popular scenarios for using the phone-TV bundle.

 

Why display information from the phone to the TV

Connecting the smartphone to the TV provides comfortable viewing of various content. And connecting a wireless mouse and keyboard allows you to partially replace the computer. Here are the most common use cases:

  • View photos and videos from your phone’s camera.
  • Communication in social networks.
  • Internet using.
  • View streaming broadcasts, streaming services, local video.
  • Reading books and magazines, working with office documents.
  • Running mobile games.

 

Method 1: wired connection

micro HDMI

Wired connection is mainly implemented in smartphones released before 2013, where there is a micro HDMI connector. To display a picture, it is enough to connect one end of the cable to the phone, and the other to the TV or monitor. The connection process is instant and does not need to be configured. The maximum that may be required is to specify the resolution of the displayed image in the system settings of the phone. After connecting, all information on the screen of a mobile phone is automatically copied to the TV/monitor screen.

The main connection condition is the presence of an HDMI connector in the output device. Adapters or converters of a digital signal to analogue help to replace the required connector. The latter allows you to connect the phone to old TVs and monitors with a VGA port.

Mhl

Another wired connection method is MHL or Mobile High-Definition Link. In this technology, the port for video output is located in the microUSB connector. To connect, use the appropriate adapter with an output to HDMI, where data lines are used to transmit video. The phone’s charge is used for power, which significantly reduces the time of active work. The problem is solved by using an adapter, where there is a separate port for charging the smartphone.

MHL technology is supported by a limited number of models, see the full list on this page. For this, technology is found in phones released until 2016, for example, in the Samsung Galaxy Note 8.

 

Slimport

An alternative to MHL is SlimPort. The principle of operation is similar – one end of the cable needs to be connected to the microUSB port of the phone, and the other to the TV or monitor. On sale there are also adapters for HDMI, for VGA, for VGA and HDMI in one case, and also with a built-in reader for SD and MicroSD cards.

The key advantage of SlimPort is the reduction in the energy load on the mobile device. External power is not required for operation, and an additional microUSB connector will also allow recharging the smartphone. At the same time, the number of supported devices is also not very diverse. A complete list is available on the official website.

 

USB Type-C

With the active introduction of the USB-C connector, where there is a separate line for video transmission, it became possible to connect modern flagship models to the TV, rather than devices 2-3 or 5 years ago. A prerequisite is the presence of a USB-C 3.1 port and support for the video transfer function. To do this, contact the phone manufacturer and clarify the availability of such an opportunity.

Samsung remains the traditional leader in this area, where the flagship models in combination with the DeX Station are able to work in netbook mode. After connecting the dock to the TV / monitor and installing the phone, the desktop is displayed on the screen with the ability to launch a browser, applications, video, etc.

If the phone supports image output, DeX Station will easily replace any multiport adapter that has a connector for charging the phone, HDMI for displaying pictures on the screen and a USB port for connecting peripherals.

In the future, the number of compatible devices will increase as Google is working on the “desktop mode” feature. As planned, a smartphone connected to a TV / monitor will switch from a mobile version of the system to the desktop, where there are more multitasking capabilities.

Method 2: wireless connection

Wi-Fi Direct

Most smartphones and TVs with Wi-Fi support the “Wi-Fi Direct” function. The principle of operation is to create an individual network, after which the phone acts as a multimedia device. Connecting is similar to connecting to a Wi-Fi router: on the TV, you need to enable detection, and on the phone, search for a new device. After establishing a connection, you must select a photo or video, for example, through a file explorer, and then send the contents via the Wi-Fi Direct channel through the “share” function.

This translation method is suitable for transferring large files. If the phone or TV has a weak Wi-Fi module, there may be crashes and freezes.

 

DLNA

DLNA is supported by most smartphones and is present on Smart TVs. At the same time, communication is not established directly, but via a Wi-Fi router. When both devices are connected to the same router, you need to select DLNA mode on the TV. To broadcast content, for example, in the gallery, you need to select a photo or video, and then click on the “broadcast” button. In some models, you must click on the “share” button, where to select the appropriate action. At the end, indicate the playback device.

Watching movies or streaming with DLNA is more enjoyable due to the high bandwidth of the Wi-Fi router. And since the server is a mobile device, there are no compatibility problems with the formats.

 

Miracast

Miracast technology first appeared in Android 4.2 and is supported by most mobile devices. To broadcast content, a compatible TV and phone also need to be connected to the same router. Then, select “wireless display” or “broadcast” in the smartphone’s menu, and then select TV from the list. After establishing a connection, automatic broadcasting will begin, and everything that appears on the phone screen will also be displayed on the TV screen.

With Miracast it’s convenient to view any content from your phone – books, magazines, videos, photos, etc. Use a browser and play games. At the same time, for dynamic games and high-definition video, it is important to use a router with a high bandwidth, otherwise frame drops are inevitable.

Method 3: wirelessly connect using the adapter

Not all users own modern Smart TVs with built-in Wi-Fi module. Therefore, to display the image on such TVs, you need to purchase a “smart filling” in the form of an adapter with an external connection. Visually, the device resembles a large USB flash drive or set-top box without control elements. The adapter connects to the TV via an HDMI connector and additionally needs external power. After connecting, the setup instructions for Miracast, DLNA or another mode will appear on the TV screen.

When choosing an adapter, be it the eminent Chromecast developed by Google or the Chinese counterpart, carefully study the internal characteristics. It is recommended to consider models with at least 2 processor cores, 512 MB of RAM and at least 256 MB of flash memory.

 

Conclusion

Now you know how to display the image from the phone to the TV. In most cases, you will have to use a wireless connection, since microHDMI, MHL and other obsolete specifications are absent in modern smartphones. And to transfer information via the USB-C port, mainly some flagships are able to. If the TV does not have Smart functions and a Wi-Fi module, then you will have to get an adapter, which will replace smart stuffing. And if the TV does not yet have an HDMI port, you will additionally have to get a signal converter.
