This task seems simple only at first glance: the choice of method depends on the TV model, version Android-smartphone on the big screen, but don’t know how to properly connect it to the TV? This task seems simple only at first glance: the choice of method depends on the TV model, version Android, the presence of additional adapters and even on the firmware of the devices. In 2026, new wireless transmission standards appeared (for example, Wi-Fi 6E), and manufacturers began to abandon classic connectors in favor of universal ports - this complicates the process for beginners.

In this article we will analyze all current connection methods - from wired ones (via HDMI or USB-C) to wireless (via Miracast, Google Cast or proprietary technologies Samsung DeX/Xiaomi Wireless Display). You'll learn which method gives you the lowest latency for gaming, how to get around the limitations of older TVs, and what to do if your connection keeps dropping. And at the end - unique compatibility table of smartphone and TV brandswhich is not in other guides.

1. Wireless connection via Wi-Fi (Miracast, Google Cast, Screen Mirroring)

The most popular method is to transmit images over the air wirelessly. To do this, both devices must support one of the protocols:

  • 📶 Miracast —a universal standard for screen mirroring (works on most Androiddevices and TVs after 2014).
  • 🎯 Google Cast —technology from Google (used in Chromecast and many smart TVs). Allows you not only to duplicate the screen, but also to stream content directly from applications (YouTube, Netflix).
  • 🔄 Screen Mirroring - proprietary solutions from manufacturers (Samsung Smart View, Xiaomi Wireless Display, LG Screen Share).

To connect:

  1. On the TV, activate the signal reception mode. This is usually done through the menu Settings → Network → Screen Mirroring or Source → Wireless Display.
  2. On your smartphone, open Settings → Connected devices → Screen sharing (on Samsung) or Settings → Display → Wireless display (on clean Android).
  3. Select the name of your TV from the list of available devices.
