Modern smartphones are full-fledged multimedia centers. They do not have problems even playing movies in Ultra HD. But you will not watch blockbusters on the display with a diagonal in the best case of six inches? Here it comes to the rescue and the opportunity comes to connect the gadget to the TV. Yes, and looking for a on YouTube, typing its name from the remote control, is quite inconvenient. it’s easier to stream from a smartphone. And, of course, showing the whole family the photos ands captured on it is much more comfortable on the TV screen. What methods for pairing a smartphone and TV exist and what you need. we will tell in the article.

You can connect a smartphone to a TV or monitor with a wire in at least three ways. over, the choice of specific for old gadgets is determined by their capabilities, and for modern flagships. only by your preferences. Let’s consider everything in order.


To date, the most common way to connect your smartphone to a TV or monitor is the rather confusing MHL standard. The reason for the difficulties lies in the fact that MHL defines only the method of transferring data to the HDMI input of an external monitor, but not the requirements for a physical interface. As a result, in addition to the four versions of the MHL standard, there are at least four physical interfaces. Fortunately, an ordinary user does not need to know about this. just purchase an adapter.

The only thing to worry about is to find out in advance whether your device supports MHL in principle. With most flagships and devices close to them in terms of characteristics and positioning, there will be no problems. But it will be useful to verify this on the manufacturer’s website or to find out about the availability of support from smartphone owners.

You don’t need to worry about the fact that you have a USB Type-C connector in your smartphone, or vice versa, Micro-USB: cables and adapters for both types of connectors are sold on the Chinese platforms in assortment. Keep in mind that most MHL adapters require external power to operate. Despite the existence of “passive” adapters that do not require additional cables, they must also be supported by the TV and are not widely used.

SlimPort is the same MHL, only based not on HDMI, but on the DisplayPort standard. However, you may not even notice this: there are a huge number of SlimPort adapters with an HDMI connector at the output. Historically, this standard was used on a non-alternative basis in smartphones of the Nexus line, primarily due to the absence of the need for Google to pay royalties. Now the standard is almost extinct, and if it is found in new devices, then, as a rule, together with MHL. View a list of compatible devices on the official website of the standard developer.

USB Type-C DisplayPort Alternate Mode

One of the features of the new USB 3.1 standard and USB Type-C connector is the ability to programmatically use some of the connectors of the latter for other data transfer protocols. the so-called Alternate Mode (alternative mode). DisplayPort Alternate Mode (abbreviated as DP Alt Mode) has spread to smartphones. As you might guess, the mode provides direct transmission of DisplayPort signals to the USB Type-C connector. The main advantage of using DP Alt Mode is that there is no need for external power. On the other hand, this can be a minus: connecting a smartphone to a TV and charging at the same time will be possible only through special docking stations, or you will have to take a wireless charger.

Despite its name, DP Alt Mode is also compatible with HDMI and even DVI standards. it all depends on which cable you choose. Well, you can use it not only with a smartphone, but also with any laptop that supports Thunderbolt 3.

Smartphones with DP Alt Mode support can still be counted on the fingers: they include Huawei Mate 10, Samsung Galaxy S8 / S9, Microsoft Lumia 950 and LG G5. In a word, all the new products that are equipped with USB version 3.1, and the number of such gadgets will only grow over time.

Despite the development of USB and Thunderbolt interfaces, the future, according to many, is for wireless technology. There is already not enough to buy a simple cable or adapter: if your TV is “stupid”, you have to fork out for a special dongle.


This independent standard was developed by the Wi-Fi alliance and uses Wi-Fi Direct technology to connect the smartphone to the TV. Android natively supports technology from version 4.2 of KitKat. However, depending on the manufacturer of the gadget, the corresponding application may be called differently. For example, in the smartphones of the Honor line, the name MirrorShare is used. The standard is widespread: it is supported by all modern Android devices and most smart TVs.

Even if you have a “stupid” TV (or even a regular monitor) at home, you can easily add Miracast support to it by connecting one of the many specialized dongles or a set-top box with the Miracast server function. We tested Miracast with the Honor 9 Lite smartphone and the Prestigio PMD-1 dongle.

Such a bundle does not involve any fuss: just select MirrorShare in the smartphone’s settings, and then select the name of the detected dongle. Connection takes about 20 seconds, after which a duplicated image from the smartphone appears on the monitor screen. There are no difficulties with a time lag or low fps, but we must remember that the resolution when using Miracast has a limitation of 1920×1200 pixels.

The cheapest Miracast-enabled dongles are no more expensive than special cables. But in order to avoid problems, it is better to pay attention to the gadgets of trusted manufacturers.

Solution Price: free (with Smart TV) or from 600 rubles (dongle).


Google sells its own dongles for broadcasting content to TVs. Chromecast. This technology is closed and fundamentally different from Miracast. If the latter is a simple “mirroring” of the smartphone screen to the TV, then Chromecast requires support for specific applications. However, among them there are many audio and players and, importantly, the Chrome browser. this should be enough for most users. In fairness, broadcasting the entire smartphone display has also been supported in Chromecast for some time now, but it doesn’t work at all perfectly.

But with Chromecast, the smartphone becomes multitasking. So, starting to broadcast the from YouTube, you can open any other program or even block the gadget. playback will still continue.

Unlike Miracast, which uses Wi-Fi Direct, Chromecast requires a Wi-Fi router to work, which somewhat limits the scope of the device.

Solution Price: from 2500 rubles.

Each of the proposed methods for transmitting pictures from a smartphone to a TV has its own advantages and disadvantages. If you want maximum quality at a low price, you should choose a wired method, if you care only about convenience. Miracast, and for maximum flexibility and the ability to broadcast Ultra HD. Chromecast. True, in the latter case, the budget will exceed 5,000 rubles, so it all depends on your needs.
