How to use your TV as an extended screen without cables

Technological advancements have made it increasingly unnecessary to have cables. This solves a problem in small apartments, where they take up too much space. At the same time, they aren't the best companion aesthetically speaking.

Therefore, it's very useful to know how to use your TV as an extended or mirrored screen for your PC, laptop, or cell phone without a single cable. This increasingly popular feature is a solution for those seeking greater comfort while working, studying, or simply a more immersive viewing experience.

Therefore, from now on we will review the process step by step and answer the most frequently asked questions on the subject.

The most common way to project your PC or cell phone screen onto your TV wirelessly is through wireless mirroring . This can be done using various tools, such as Miracast, Google Cast, AirPlay (on Apple devices), or your TV's own brand of apps.

Miracast is a wireless standard developed by the Wi-Fi Alliance that provides the option of mirroring the screen of a Windows or Android device to a compatible TV. Most modern smart TVs, such as theSamsung RU 7100 or TCL 55P635, come with support for Miracast or identical technologies under other names (such as "Screen Mirroring").

To use Miracast on your PC, we recommend first checking that your computer is running Windows 10 or higher. Then, press Windows + K and select your TV. Finally, accept the connection from the TV if prompted. With all these steps, you should be able to view your PC projected on your TV.

If your TV doesn't have Miracast or you want a more stable connection, you can first select Chromecast (a Google device that connects to your TV via HDMI and allows you to project or extend your screen from Chrome, YouTube, and other apps). Then, you should turn to Fire TV Stick (a device with similar features to Chromecast that also supports wireless screen mirroring). Other apps like AirDroid Cast, LetsView, or ApowerMirror, which allow you to stream your screen from your PC or phone to your TV.

When we talk about expanding, we mean using the TV as a second screen, not a duplicate. This is especially useful if you plan to work on two different screens and have, for example, a presentation on the TV and notes or controls on your laptop.

To extend your screen on Windows devices, we recommend following these steps. First, connect your TV via Miracast, then right-click on the desktop and choose "Display Settings." Finally, in the "Multiple Displays" section, select the "Extend these displays" option. Finally, arrange your displays according to your preferences and start working more comfortably.

Both a larger screen size, as well as better viewing for design or editing tasks, and the ability to multitask.

This has some minimum requirements. First, your TV must be a Smart TV and compatible with Miracast, Google Cast, or similar apps. Also, your computer must have built-in Wi-Fi and an updated operating system. And finally, both devices must be connected to the same Wi-Fi network.

If you're using Windows 10 or higher, you have built-in wireless projection, so you simply need to press Windows + K or type "connect" in the Windows search bar. After your TV appears on the screen (for example, Samsung RU7100), click on its name and wait for the connection to begin. Finally, it's recommended that you grant permission from your TV to establish a full connection.

This situation can occur for any of these reasons. First, both devices may not be connected to the same Wi-Fi network. Another possibility is that the TV doesn't have the mirroring feature enabled, or that your computer's operating system isn't up to date. Another possibility is that you have incompatible devices.

On Android phones, you can use the Smart View feature, Screen Cast, or Cast Screen, depending on the manufacturer. On Samsung phones, for example, you have to open the quick menu (swipe down). Then search for "smart view" and select your TV. Finally, accept the connection.

Meanwhile, on iPhone, you can use AirPlay, as long as your TV is compatible or you have an Apple TV connected.

First, ensure a strong Wi-Fi signal. And the closer your devices are to the router, the better. Second, close programs that aren't being used on your computer to avoid slowdowns. It's also recommended to adjust the resolution to what your PC or network supports to avoid interruptions. Finally, keep your software as up-to-date as possible.

Yes. Using a TV as an extended display is valuable for both gamers and those working from home. The Samsung RU7100, for example, features a “Game Enhancer” mode that reduces input lag, highly recommended for playing on a console or from a wirelessly connected PC.

Turning your TV into a wireless display is a great solution for working, gaming, watching movies, or enjoying the Superclásico on a bigger screen. All you need is a stable Wi-Fi network, compatible devices, and a few minutes to set everything up.

Now that you know how to do it, get the most out of your TV!
