Broadcast video from your smartphone screen to a large TV screen via Wi-Fi — is a convenient way to enjoy content wirelessly. But not everyone knows that there are several technologies for this, each suitable for different situations. Someone wants to stream a movie from YouTube on Samsung Smart TV, and someone needs to mirror the screen iPhone on LG OLEDIn this article, we'll cover all the current methods—from built-in functions to third-party apps.
The main difference between the methods is in the supported devices and transmission quality. For example, Miracast It works without the Internet, but it can slow down at high resolutions, and DLNA Streams files but doesn't mirror your screen. We've tested each method on popular TVs and smartphones to help you choose the best option.
If you have already tried to connect and nothing worked, please pay attention to common mistakes: protocol version incompatibility, manufacturer limitations, or incorrect router settings. At the end of this article, there's a FAQ with solutions to common problems.
1. Miracast: Direct wireless mirroring without a router
Miracast — is a wireless image transmission standard that operates on a point-to-point principle. It does not require an internet connection, but both devices must support the technology. Most modern Android- smartphones (starting with version 4.2) and Smart TV (produced after 2013) are equipped with Miracast, but at Apple he is not there - to the owners iPhone This method will not work.
The main advantage is minimal delays (up to 50 ms), which is important for gaming or video calls. However, when transmitting video in 4K Artifacts may occur if the router is weak or the walls are thick. Also Some manufacturers (for example, Xiaomi) block Miracast in their shells - in this case, only third-party software will help.
How to enable:
- 📺 On TV: go to
Settings → Network → Miracast(orScreen Mirroring,Wireless Display). On Samsung this can be calledSmart View. - 📱 On Android: Open
Settings → Connected devices → Screen sharing(orCast,Smart Viewin the notification bar). - 🔍 Select your TV from the list of available devices. Confirm the connection on both screens.
⚠️ Note: If your TV is not listed, check if the TV is in the "Show TV" mode.Device discoveryOn some models Sony Bravia This option is hidden inSettings → External Inputs → Miracast.

Both devices are connected to the same network (or in ad hoc mode)
The TV is in discovery mode-->
2. DLNA: Media Streaming
DLNA (Digital Living Network Alliance) is a protocol for exchanging multimedia over a local area network. Unlike Miracast, it doesn't mirror the screen, but transfers specific files: video, music, or photos. It is supported by almost all Smart TV and smartphones, including iPhone (through apps like Infuse or VLC).
The main advantage is stable operation even on weak routers, since no screen synchronization is required. The disadvantage is that streaming services cannot be broadcast (Netflix, YouTube) or games. Also DLNA does not support DRM-protected content (for example, movies purchased from Google Play).
Instructions for Android:
- Install a media server application like BubbleUPnP or LocalCast.
- Turn on DLNA on TV:
Settings → Network → DLNA(orMedia server). - In the app on your phone, select the file and click "Play on...". The TV should appear in the list.
For iPhone:
- 📱 Download VLC for Mobile or Infuse.
- 🔌 Connect both devices to the same Wi-Fi network.
- 🎬 In the app, select the file and tap the broadcast icon (usually in the upper right corner).

|---|---|---|---|---|
| Miracast | ❌ No | ✅ Yes | Low (20-50 ms) | ❌ No |
| DLNA | ✅ Yes (via apps) | ❌ No | Average (100-300 ms) | ✅ Yes |
