Agree, launching mobile games, as well as watching movies, photos ands stored in the smartphone’s memory, is much more convenient on the big screen. To do this, just connect the phone to the TV. You can do this in many ways. both by cable and without. And it is not necessary to own the latest generation TV. It is enough that it supports at least one technology for receiving signals from mobile devices.
Wi-Fi Direct technology is supported by almost all TVs equipped with a Wi-Fi module, and most modern smartphones (except for those working on earlier versions of Android). Its essence is to connect devices to each other without the mediation of an access point. The phone is recognized by the TV as a multimedia device, not a drive.
The general instruction for pairing a smartphone and TV via Wi-Fi Direct looks like this:
- First, activate Wi-Fi Direct mode on your smartphone. On devices with any version of the OS, it is located in the wireless settings, but in different places.
- Next we do the same on TV. The option is also located in the network settings, but on devices of different brands its location is slightly different. To clarify how this is done with you, look at the instructions.
- After you turn on Wi-Fi Direct, the TV displays a list of devices available for connection. Among them should be a smartphone. Select it and enjoy watching mobile content on the big screen.
Miracast is a newer and more advanced technology based on Wi-Fi Direct, but supported by fewer devices. Like Direct, Mirakast connects devices directly. without a router.
In the list of the main advantages of Miracast:
- The best quality transfer of heavy media content (convenient for watching movies).
- Connection security using WPA2 encryption.
- The ability to display both the smartphone screen on TV, and vice versa.
- Support for 3D and surround sound.
- Battery Saving Mobile Gadget.
Connection (general instruction):
- Turn on Miracast mode in the TV settings.
- We go on the smartphone in the “Display” (“Screen”) section and select the TV in the list of available output devices.
There is another technology that works this way. Intel WiDi. If your TV does not support Miracast, but supports WiDi, use it. You probably won’t notice the difference.
By the way, for TVs that do not support Miracast, adapters are available that make up for this feature. They look like a regular large USB flash drive, but are connected to the HDMI port.
Proprietary technologies from manufacturers
If your phone and TV support Wi-Fi Direct or Miracast, these communication methods will seem to you the most convenient. However, some electronics manufacturers have gone further and introduced standards that further simplify the connection of devices of the same brand.
So, to connect a Samsung phone to a Samsung TV, just activate the “AllShare” function on both. An analogue of this feature from LG is called “Smart Share”. Users of Apple TV set-top boxes can connect their iPhones to TV using “AirPlay”, and Sony brand followers can use “VAIO Media Server”.
Proprietary technologies include a host of other goodies and “goodies”. For example, transcoding and audio. quickly converting data to a format that supports a television receiver; automatic improvement of picture quality; using your phone as a remote control and much more. However, to ensure communication between devices, some of the technologies require an access point because they do not provide a direct connection.
If your smartphone is equipped with a micro- or mini-HDMI port, which is not so common, you are lucky who has access to the simplest wired connection option. HDMI-HDMI. Of course, if the telly also has such a connector. In other cases, you will need an adapter adapter.
The procedure for connecting TV and phone:
- Turn off both devices (unplug the TV from the wall outlet).
- Connect the ends of the cable to the appropriate jacks.
- Turn on the TV and smartphone.
- On the TV menu, select the HDMI port as the source. After that, the phone screen will be displayed on the TV.
In addition, in the HDMI settings (on the TV), you can specify the resolution and frequency of the image if there are problems during the automatic setup.
HDMI connection is convenient, but has several disadvantages. The most annoying is the quick discharge of the smartphone battery. This means you have to keep it constantly connected to the charger, and this is sometimes impossible (if the ports are close and the cable of one blocks access to the other). In addition, some older Android phones do not transmit all the content via HDMI (for example, only pictures in a slide show) or require the installation of additional applications.
To connect phones without an HDMI connector to this type of port, you can use the micro-USB-HDMI adapter, but better. MHL, which will be discussed below.
MHL is a more advanced and modern standard for wired connection of mobile gadgets and TV. It is implemented using special cables or conversion adapters, which are connected to the micro-USB port at one end and HDMI to the other. Unlike the HDMI-HDMI connection, MHL provides power to the connected device, which is very convenient, as well as better playback quality and higher data transfer speed.
There are two types of MHL cables and adapters. passive and active. Active ones require additional power, for which they have another USB port (via USB such an adapter connects to TB).
Passive cables are only compatible with devices that mutually support the MHL standard. It is enough active that MHL is supported only by the playback side (TV), and the phone is not necessary.
Physical connection of devices via MHL is carried out in the same way as HDMI, so we will not consider it separately.
By the way, gadgets with SuperMHL support will soon appear on the market. the next stage in the development of this technology. The advantages of the new product are higher quality transmission (resolution 8K, color depth 48 bits, frame rate. 120 per second), support for surround sound and the USB Type-C standard. Ports of this type are equipped with many smartphones of the latest generation.
SlimPort is another new technology for combining mobile devices and TV into an integrated system. It works through a special adapter, which connects to the USB port of the phone on one side and the other to the TV’s HDMI, VGA, DisplayPort or DVI port. This, perhaps, is its main difference from MHL.
Other significant differences are clearly not in favor of SlimPort. Firstly, SlimPort does not power the mobile device (although for this there is another micro-USB port on the adapter itself where you can insert the charger). Secondly, it can only be used on devices that mutually support the technology, and there are not too many of them yet.
Connect your phone to an old TV
It’s good to be the owner of Smart TV. there are plenty of options for connecting the phone to such a device, but what about the owners of old TV boxes? We hasten to reassure you: there are fewer ways to connect to an old TV, but they also exist.
Old devices, as a rule, are equipped with one or two external interfaces, for example, RCA (tulips), VGA, S-or SCART. And the phone’s output is still the same micro-USB. In some cases, the Jack 3.5 headset port is still used to communicate with the TV, and the 20-pin service connector on the iPhone.
To connect these incompatible devices with each other, of course, adapters are needed. For instance:
- RCA-Jack 3,5.
- SCART-USB-micro-USB, etc.
Alas, you cannot get a good image when transmitting a signal through an adapter. In addition, most of them do not support audio transmission.
A more expensive but reasonable alternative to the shoelaces is a television set-top box. This is a device capable of endowing a conventional TV with Smart features. One of these consoles was already mentioned in the article. Apple TV, but besides it there are many others. based on Android systems and familiar Windows.
The prefix will turn your old telly into a completely modern computer with a lot of interfaces for connecting peripheral devices. And the problem of connecting to a mobile phone will disappear by itself.
