Whether it’s to share videos of a family trip, follow a training routine or enjoy some video games, many times, one needs to connect their phone to an XXL screen. All the tricks to achieve screen mirroring in just a few steps.
To replicate the phone screen there are several methods. All require an element that meets the role of intermediary –can be a wireless protocol or a hardware adapter- between the two devices.
The more advanced the TV is – ideally it should be a Smart TV – the simpler it will be to establish a link. In terms of fit, Android devices also have an advantage over iPhones.
high definition link
If you travel frequently and don’t know 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 micro USB or USB-C, to link to the mobile.
The main feature of MHL is the possibility of transmitting uncompressed high-definition image (support 4K and 8K) and surround sound. The price depends on the quality and type of connector.
The cheapest is around 2 thousand pesos. The ones that come with a meshed HDMI, are almost double. Before buying it, you have to find out if the phone supports the MHL protocol.
Some introduce a third cable to receive electrical power. This particularity allows the phone to be passively charged – so that it never runs out while sharing the screen – with a power of 40W.
Furthermore, 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 totally transparent for both devices.
If the television is from the old guard, you can add a gadget to make it a little smarter. The most popular in this category is the Chromecast, developed by Google. Links to the HDMI port of any flat panel display.
This circular accessory allows you to view streaming content (Netflix, YouTube or HBO Max) on a large screen and has the ability to send videos from your mobile. The only requirement is that the phone and the Chromecast travel over the same Wi-Fi network. It also needs to be plugged into an outlet.
Every year a new version of the device appears. The most recent incorporates 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 Factory installed Chromecast. Which 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. The 4K with 8GB and control costs 18 thousand pesos. Its direct competitors are Fire TV Stick 4K Amazon and Roku Streaming Stick 4K.
To project the mobile screen without the intervention of cables, the two devices that are coupled must be compatible with a mirror function. The best known are Miracast, Digital Living Network Alliance (DLNA) and WiDi and their purpose is to banish HDMI cables.
The less advantageous side of these protocols is that, since what they do is duplicate the screen from one extreme to the other, if one wants to send a series to the television, the mobile must 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 a latency low enough to take advantage of a video game.
In addition, it supports WPA2-PSK encryption, which means that the 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 come from the factory.
Miracast works by sending the content through WiFi Direct, a technology designed for direct communication between parties and that performs the exchange at a higher speed than Bluetooth.
And while it is very competent in theory, despite constant adjustments, Miracast has not managed to be a reliable protocol and on many occasions, for no apparent reason, it fails to work.
To pair the phone, you will have to turn on the Smart TV and in the quick settings menu, locate the Send screen icon. Its name varies depending on the model and manufacturer. It can appear as Screen Cast, Smart View, or Screen Share.
The name of the closest TV is then displayed in a floating menu. Clicking on this link activates the link between both devices.
The Digital Living Network Alliance is an association between various manufacturers of electronic equipment whose objective was to define the specifications that allow multimedia content to be shared between different equipment on the same network.
And although the alliance was dissolved a few years ago – since the balance tips towards paid video streaming – it is still working on the first SmartTVs with 4K resolution.
This protocol was born to establish a communication with home multimedia servers, computers and consoles. The idea was to empower the television as an entertainment center.
Thus, the device that has the stored content is designated as a server, while the rest, officiate as customers or recipients of that information. It is more comfortable and faster than the old USB or hard drives that were adapted to televisions.
There are some apps that were written to take advantage of the DLNA protocol from within Android. One of the best known is Kodi. It is a historic multimedia center that allows you to view content – digital channels free of charge – through its multiple add-ons.
BubbleUPnP and LocalCast tune to the same frequency, although they are a bit more complex and require some advanced configuration steps.
This proprietary Apple technology allows you to play different multimedia content. AirPlay is the answer to Google Cast. It comes built into Apple devices like iPhone, HomePod, iPad, and Mac. It can also be ported to Windows using iTunes.
It was released in 2004 under the name of AirTunes. Its last major update was at the beginning of 2018, when AirPlay 2 was launched, capable of creating multiroom experiences to distribute the sound in several rooms.
There are some Smart TV manufacturers such as Samsung and Sony that offer support for this protocol. Also, LG models equipped with the webOS operating system from 2018.
The procedure could not be more direct. 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 many. Whether with adapters or powerful equipment, the goal can be met in a variety of ways.
It is a matter of thinking about which one is the most suitable.
