Whether it’s sharing videos of a family trip, keeping up with a workout routine, or enjoying video games, you often need to connect your phone to an XXL screen. All the tricks to perform screen mirroring in just a few steps.
To mirror the phone screen, there are several methods. All require an element that meets the role of intermediary –can be a wireless protocol or hardware adapter- between the two devices.
high definition link
If you travel frequently and aren’t sure what kind of screen you’ll be dealing with in your hotel room, the best option is to pack a Mobile High Definition Link (MHL).
This adapter, at one end, has an HDMI input -the cable is not always included- and at the other it can be a microphone USB or USB-C, to link with on mobile.
The main feature of MHL is the ability to transmit an uncompressed high-definition image (support 4K and 8K) and surround sound. The price depends on the quality and type of connector.
Cheapest is around 2 thousand pesos. Those that come with a mesh HDMI, are almost double that. Before you buy it, you need to know if the phone supports MHL protocol.
Some introduce a third cable to receive the electrical energy. This particularity allows the phone to be charged passively – so that it never runs out while sharing the screen – with a power of 40W.
Moreover, the connection does not require additional software, since it includes a driver that converts the smartphone’s USB signal to HDMI and vice versa, so everything is done without external functions and completely transparent for both devices.

If the TV is old-school, you can add a gadget to make it a bit smarter. The most popular in this category is the Chromecast, developed by Google. Connects to the HDMI port of any flat screen.
This circular accessory allows you to view streaming content (Netflix, YouTube or HBO Max) on the big screen and has the ability to send videos from your mobile. The only requirement is that the phone and the Chromecast traveling on the same Wi-Fi network. It must also be plugged into an outlet.
Every year a new version of the device appears. The most recent integrates the Google TV system to run applications, a remote control to facilitate interaction and voice recognition.
Many Smart TV models – such as Sony and Philips – come with the Chromecast factory installed. This means you can cast your screen directly to your TV from the Google Home app.
The most basic model starts at 8 thousand pesos and it’s Full HD. 4K with 8 GB and control costs 18,000 pesos. Its direct competitors are Amazon’s Fire TV Stick 4K and Roku Streaming Stick 4K.
To project the mobile screen without the intervention of cables, the two paired devices must be compatible with a mirror function. The best known are Miracast, Digital Living Network Alliance (DLNA) and WiDi and their goal is to banish HDMI cables.
The less advantageous side of these protocols is that, as they duplicate the screen from one extreme to the other, if we want to send a series to television, the mobile should always remain on.
Miracast is a wireless communication standard promoted by the Wi-Fi Alliance and compatible with the vast majority of portable devices. transmission in 1080p is very stablewith low enough latency to enjoy a video game.
In addition, it supports WPA2-PSK encryption, which means that data that travels from one device to another will be protected against intruders.
All Android mobiles, from version 4.2, are compatible with Miracast. In addition, the Smart TV must be certified. LG, Samsung, Philips and Sony models leave the factory.
Miracast works by sending content over WiFi Direct, a technology designed for direct communication between parties and which performs the exchange at a higher speed than Bluetooth.
And while it’s very capable in theory, despite constant tweaks, Miracast has failed to be a reliable protocol and many times, for no apparent reason, it doesn’t work.
To pair the phone you will need to turn on the Smart TV and in the quick settings menu look for the send screen icon. Its name varies by model and manufacturer. It can appear as Screen Cast, Smart View or Screen Share.
The name of the nearest TV is then displayed in a floating menu. Clicking on this link activates the link between the two devices.
The Digital Living Network Alliance is an association between different manufacturers of electronic equipment whose objective was to define the specifications allowing the sharing of multimedia content between different equipment on the same network.
And although the alliance was dissolved a few years ago – since the scales are tilting paid video streaming– it still works on early SmartTVs with 4K resolution.
This protocol was born to establish communication with home media servers, computers and consoles. The idea was to make television a center of entertainment.
Thus, the device that owns the stored content is designated as the server, while the others officiate as customers or recipients of this information. It’s more comfortable and faster than older USB drives or TV-friendly hard drives.
Some apps have been written to take advantage of the DLNA protocol from Android. One of the best known is Kodi. It is a historic multimedia center that allows you to view content – free digital channels – through its multiple add-ons.
BubbleUPnP and LocalCast tune to the same frequency, although they are a bit more complex and require advanced configuration steps.
This Apple proprietary technology allows you to play different media content. AirPlay is the answer to Google Cast. It is built into Apple devices such as iPhone, HomePod, iPad, and Mac. It can also be ported to Windows using iTunes.
It was released in 2004 as AirTunes. Its last major update dates back to the beginning of 2018, when it launched AirPlay 2, capable of creating multiroom experiences to distribute sound in several rooms.
Some smart TV manufacturers such as Samsung and Sony offer support for this protocol. Also, LG models with webOS operating system from 2018.
The process couldn’t be more straightforward. Look in the Tools menu and click on the Duplicate Screen icon. The iPhone will recognize the name of the second TV and display its name.
Thus, the current options to replicate the screen are numerous. Whether with adapters or powerful equipment, the goal can be achieved in different ways.
It is a question of thinking about which one is the most suitable.
