How to Mirror Your Laptop Screen to a TV via Wi-Fi: A Step-by-Step Guide

Mirroring your laptop screen to your TV via Wi-Fi is a convenient way to show a presentation, movie, or game on a big screen without the hassle of wires. But it's not always clear which method to choose: built-in operating system features, third-party apps, or proprietary technologies from TV manufacturers. In this article, we'll explore all the current wireless screen mirroring methods, their pros and cons, and common errors that can interfere with the connection.

It is important to take into account that the stability of the connection depends not only on the chosen method, but also on Wi-Fi router power, network congestion, and even the distance between devices. For example, Miracast may slow down when the signal is weak, and Google Cast requires a stable internet connection. We tested all methods on different TV models (Samsung QLED 2023, LG OLED C2, Sony Bravia X90K) and laptops (Windows 11, macOS Ventura, Ubuntu 22.04) to provide objective recommendations.

If you have previously tried to connect but it didn't work, check Compatibility of protocols between your laptop and TVFor example, many budget models Smart TV on Android TV 9 do not support Miracast, but they work with Google Cast through apps like YouTube or Netflix.
