We tested all methods on devices from 2022 to 2026 and compiled checklists for each case.

If you urgently need to show vacation photos, play a game on the big screen, or stream a movie from your phone, choose the appropriate method from our instructions. And if your connection is interrupted or the image is lagging, there's a troubleshooting section at the end of the article.

1. Wi-Fi Screen Sharing Methods: Comparison of Technologies

There are five main protocols for wireless screen sharing, and each operates differently. Here are their key features:

• 📱 Miracast — a universal standard for Android, Windows and some Smart TV. Works without a router (via Wi-Fi Direct), but requires TV support. Suitable for presentations and gaming with minimal lag.
• 🍎 AirPlay - technology Apple to transfer the screen from iPhone/iPad on Apple TV or compatible TVs (eg LG or Samsung with AirPlay 2 support). The image quality is higher than Miracast, but it only works in the Apple ecosystem.
• 📺 Google Cast (including Chromecast) - broadcasting not the entire screen, but only individual applications (for example, YouTube or Netflix). Minimal load on the phone, but not suitable for duplicating the desktop.
• 🔄 Smart View (at Samsung) / Screen Mirroring (at LG, Sony) are proprietary solutions from TV manufacturers. They often work more reliably than Miracast, but only with devices of the same brand.
• 🌐 Third-party applications (For example, ApowerMirror, TeamViewer) is a universal option if built-in methods don't work. It requires software installation on both devices.

The choice of technology depends on your devices. For example, if you have iPhone 15 and TV Samsung QLED 2026, That AirPlay will be the optimal solution. And for Android smartphone and the old one Smart TV Without Miracast you will have to use Google Cast or a third-party application.

⚠️ Attention: TV manufacturers periodically update the lists of supported protocols. For example, Sony In 2026, it stopped supporting Miracast on some models in favor of Google CastBefore setting up, check the specifications of your TV in the official manual.

• 🔌 Connect your phone to the charger. When the battery level is low, the system automatically reduces performance, which results in lags.
