The known methods to share the screen of a cell phone to the TV

In general, most of the images or videos that are captured with the cell phone are usually shared by this same means with other people; However, with the technological advancement, nowadays such photos and even enjoying video games that are on a mobile phone can be shared to a TV screen.

There are several methods to perform this procedure, but all of them require an element that fulfills the role of intermediary, which can be a wireless protocol or a hardware adapter, between two devices. It is worth mentioning that the more advanced the television is, the simpler the process to establish this link will be.

high definition link

People who travel frequently and do not know what type of screen is the one where they are staying, the best option is to carry a mobile high-definition link (MHL). This adapter, at one end, has an HDMI input and at the other, it can be micro USB or USB-C to connect the mobile. As such, the main feature of MHL is the possibility of transmitting the image in high quality and surround audio.

It is important to mention that the connection does not require additional software, since it includes a driver that converts the USB signal from the mobile device to HDMI and vice versa.

In case of having old televisions, you can add a gadget to make it a little smarter. A well-known one is the Chromecast, developed by Google, which connects to the HDMI port of any flat screen. This 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.

However, to be able to use this option, the only requirement is that the phone and the Chromecast travel through the same Wi-Fi network and, in turn, it requires being plugged into a socket.

screen mirroring

In order to project the mobile screen without wires, the two paired devices must support a mirroring function. Among the best known are: Miracast, Digital Living Network Alliance (DLNA) and WiDi and its purpose is to banish HDMI cables.

However, a disadvantage of this method is that when duplicating the screen from one end to the other, if you want to send a series to the television, the mobile must always remain on. As for Miracast, it is a wireless communication standard promoted by the Wi-Fi Alliance and compatible with the vast majority of portable devices.

The Digital Living Network Alliance is an association whose purpose is to define the specifications that allowed multimedia content to be shared between different computers on the same network. This method is still available on SmartTVs with 4K resolution.


This type of technology is from Apple and allows you to produce different multimedia content. As such, AirPlay is the answer to Google Cast and comes built into Apple devices like the iPhone. To use this option, you must search for the tools menu and click on the Duplicate screen icon. The iPhone will be able to recognize the name of the TV to pair with.

The Philips Airplay has WiFi to play music from any computer connected to the network.

What type of television consumes more energy and why? we tell you

According to experts, televisions are part of the appliances that consume the most energy in the home, representing about 12% of the electricity that a home uses per month.

In that order of ideas, The TVs that use the most electricity are:

  • Plasma screen TVs, especially if they are large
  • LCD screen televisions,

Therefore, for now, LED technology would be a highly efficient option in terms of energy efficiency. However, there is now a new technology that promises to provide better electricity consumption and without affecting image quality.

These are QLED screens, which are made up of organic micro bulbs that turn on and off individually, a situation that does not occur with LED screens, which must use liquid microcrystals that do not turn off independently. This system helps to reduce the amount of energy that the TV needs to project an image.

In fact, this scheme also helps to have a better contrast and more defined blacks, which can be of very useful when playing video games that take place in dark settings.
