Wirelessly streaming your laptop screen to your TV via Wi-Fi is a convenient way to show a presentation, movie, or game without the hassle of wires. However, not everyone knows that there are several technologies for this, each with its own rules. In this article, we'll cover all the current methods: from built-in Miracast to proprietary solutions Samsung Smart View And Apple AirPlay.
The main difference between wireless and wired (via HDMI) transmission is the absence of signal lag when configured correctly. However, there are some pitfalls: not all TVs support modern standards, and older models may require additional adapters. We'll help you figure out which method is best for your device.
Important: If you have an older TV without Smart TV, first check if it supports DLNA or Miracast — this information is usually included in the instructions. If not, no problem: at the end of the article, we'll tell you how to bypass this limitation using inexpensive consoles.
1. Checking the compatibility of your laptop and TV
Before setting up a connection, make sure your devices support wireless broadcasting. Modern laptops Windows 10/11 And macOS almost always equipped with the necessary modules, but with TVs the situation is more complicated.
The main standards to look for in TV specifications are:
- 🔹 Miracast — a universal protocol for Windows and Android (supported on most Smart TVs after 2015)
- 🍎 AirPlay - Apple's proprietary technology (works only with Apple TV or TVs with AirPlay 2 support)
- 📺 Google Cast — for streaming from Chrome or Android to TVs with Android TV or Google TV
- 🌐 DLNA — an outdated standard for transferring media files (not suitable for screen mirroring)
