Mobile screens grow in size, but can not compete with the living room television to watch movies, photos or even surf the Internet.

Fortunately, the options available to duplicate the screen of our smartphone in our television have improved in recent years thanks to mobile operating systems as well as television , as well as the connectivity of home networks.

 

At the time this issue was discussed in Technology from You to You , with a good number of comments on the subject. In advance, it must be noted that it is not an easy subject to systematize . There are hundreds of different models of televisions and smartphones, as well as different ways of taking the screen of the mobile to the big screen of the room.

In any case, what is involved is to make possible daily scenarios in which, for example, we are in the living room, paying more attention to the screen of the mobile than what they are putting on TV , and we we realize that we would be better off seeing the contents of the mobile on TV instead of what they are broadcasting on the television itself.

WiFi, the connectivity that makes it possible

In all cases, as a previous step to the use of the TV as a screen to view the contents of the mobile, it is necessary to have correctly configured the local Wi-Fi home network , or the WiFi connectivity of our mobile devices and that of the TV.

The connection via network cable is also feasible, but it is less frequent than that of the Wi-Fi type , and not always easy to use: the cables are an additional burden, unless the network outlet is right next to the TV or the computer that they want to connect.

The way to use WiFi or cable technology to connect the mobile phone with the TV can be through the point-to-point connection through Miracast, WiFi Direct or WiDi, as well as through the local home network, using technologies such as DLNA, AirPlay or Google Chromecast.

You can also use a cable directly from the mobile to the screen through an MHL to HDMI cable . Actually, it is a cable with a micro USB connection on one end and HDMI on another, taking advantage of the compatibility of some smartphones with MHL (mobile high-definition link).

How do I do it?

The methods explained in some posts previously published in Technology from You to You are still valid. This time we will try to give general guidelines, along with clues to find solutions closer to televisions and mobile devices that we have taking advantage of the resources that the manufacturers themselves offer in their support pages or blogs.

In the Apple ecosystem, we continue to depend on its solutions through Apple TV and Air Play, along with apps such as Chromecast for iOS, although with less room for maneuver than Android. But in Android, whether with WiFi Direct or DLNA , with Mirascast or Chromecast among other technologies, it is easier to bring the screen of our mobile to TV.

For this it is necessary that the TV has WiFi, and configure the options to activate the shared use of the screen in the home network . Nowadays, it is a relatively easy option to find on “Smart” TVs without involving an appreciable surcharge, even on Smart TVs.

If we do not have a Smart TV, it is possible to “smart” it using accessories such as the aforementioned Apple TV or Google Chromecast, although in these cases, the options to take the screen to the TV are reduced to the use of compatible Google apps. Chromecast and Apple AirPlay .

The new operating systems for TV and mobile

The new generations of mobile devices have been adding more or less standard connectivity options suitable to bring the contents of the mobile to the big screen of the TV. Sometimes using their own solutions, with names like “HTC Connect” on HTC, which includes Miracast, DLNA or streaming audio. In Samsung, it is called “Quick Connect”, with similar functionality.

 

Android 5 and Android 6 have been incorporating the options of mirroring in an easier and more reliable way than with Android 4, and in TV sets they are using operating systems such as WebOS in LG, Tizen in Samsung, Android TV in Philips and Sony or Firefox OS in Panasonic, to give some examples.

Thanks to these operating systems, it is easier to see the content of our mobile screen on TV, although it is necessary to know where the WiFi Direct, DLNA or Miracast configuration options are .

From the general to the manufacturers’ tutorials

The general procedure for connecting the smartphone to the TV is to identify the corresponding configuration menu, both on the Smartphone and on the Smart TV within the options of Screen or Connectivity of the mobile or TV respectively. Later we offer links to the pages of some manufacturers with tutorials to access these options.

If we are using a device connected to the TV, such as Apple TV, an Android TV or Apple Chromecast , in general we will also have to resort to apps for iOS or Android that connect our smartphone with these “smartizers” of television, although the operating systems They tend to integrate compatibility with these devices natively. For example, Android 6 is natively compatible with Chromecast without the need to use the dedicated app.

The customizations of manufacturers such as HTC ( HTC Connect ), Samsung ( Quick Connect ), Microsoft (Continuum) or Sony ( Xperia Connectivity ) among others, also tend to contemplate this compatibility through their own solutions, which holds both DLNA and Miracast or Chromecast.

One of the newcomers to Smart TVs is WebOS, adopted by LG . For its part, and as we mentioned before, Panasonic has adopted Firefox OS . Sharp and Philips have opted for Android OS, and Samsung has in Tizen its proposal for smart and connected televisions.

For DLNA, the key is that the TV is connected to the same home network as our mobile device. Then, if our mobile device is also compatible with DLNA, we can enjoy multimedia content on TV through the corresponding option to share, both for the screen and for specific apps.

For Miracast or WiDi, we will have to activate this option in a dedicated menu for it on the TV . In this case it is a point-to-point connection between the terminal and the TV, and in both cases we will have to enable this form of connectivity.

It is not always possible and it depends on the devices

The possible combinations of models of televisions and models of smartphones are very diverse, and it is not always possible to systematize in a precise and infallible way how to share the screen of the mobile on the television.

The important thing is to stay with the essence of the process : set the TV to be connected to the home WiFi network, or access the configuration of Miracast / WiDi / WiFi Direct to “activate” the visibility of the screen for other devices.

For its part, on the mobile, we have to access the options to share screen , whether on Android (in version 6 without personalization there is a direct option called “Send screen”) or Windows Phone (Called “Connect to a wireless projection “), Or Apple through AirPlay and a device compatible with this technology connected to the TV.

In previous articles in Tú a Tú Technology, some examples have been exposed that, with luck, will correspond to telephones and mobile phones similar to those you may have, but in general there will be an exercise to adapt the methodology for our TV and our mobile .

 

For modern and mobile TVs with Android 5 or Android 6 or Windows Phone operating system , we can share the screen through options of the operating system itself. And with televisions of recent invoice, it is also usually possible to use apps from the manufacturers of teles to install on our mobile and facilitate the connection process. For example, Samsung has the Smart View app for this purpose. And LG has Smart Share that also facilitates the task of sharing what we are seeing on the mobile on the big screen.
