How to Stream a Movie from Your Phone to Your TV via Wi-Fi: A Complete Guide

Streaming movies and videos from your phone to a big-screen TV via Wi-Fi is a convenient way to enjoy content without the hassle of wires. However, not everyone knows that this doesn't require purchasing additional devices: modern smartphones and Smart TVs support several wireless technologies. In this article, we'll explore all the current methods, their features, and step-by-step instructions for different devices.

The main advantage of Wi-Fi streaming is the absence of latency and quality loss if the network is configured correctly. However, this also comes with a major challenge: an unstable signal or an unsuitable protocol can lead to choppy video or a complete loss of connection. We'll take a detailed look at how to avoid common pitfalls and choose the optimal method for your equipment.

1. Preparation: Checking device compatibility

Before you begin setup, make sure your phone and TV support at least one wireless technology. The main standards are:

• 📱 Miracast — a universal protocol for Android and Windows (supported by most Smart TVs after 2015)
• 🍎 AirPlay - Apple exclusive technology (requires Apple TV or a TV with AirPlay 2 support)
• 🌐 DLNA/UPnP — a standard for streaming media files (works on most devices, but with limitations)
• 🔗 Manufacturing solutions: Samsung Smart View, LG TV Plus, Sony Video & TV SideView

To check compatibility:

1. On TV: Go to Settings → Network → Wireless (The name may vary). Look for mentions of Miracast, Screen Mirroring, or AirPlay.
2. On your smartphone: For Android, open Settings → Connected devices → Wireless screen sharingOn iPhone, check for the item Screen mirroring in the control panel.

Important! If your TV was released before 2014, it most likely does not support Miracast. In this case, you will need an external adapter (e.g. Google Chromecast or Amazon Fire TV Stick).

⚠️ Please note: Some manufacturers (eg. Xiaomi) block Miracast on budget TV models. Check the specifications on the official website before purchasing.

2. Method 1: Miracast (Screen Mirroring) for Android

Miracast — the most versatile way to mirror your Android smartphone's screen to your TV without any additional devices. The technology works on a point-to-point basis, creating a direct connection between devices via Wi-Fi Direct.

Instructions for most Android devices (using the example Samsung Galaxy And Xiaomi Redmi):

1. Activate the signal reception mode on your TV:
   • For Samsung: Settings → General → External devices → Screen Mirroring
   • For LG: Settings → Network → Miracast (or Screen Share)
   • For Sony Bravia: Settings → Network → Home Network → Mirroring

On your smartphone, open Settings → Connections → Wireless Screen Sharing (or Smart View on Samsung).

Select your TV's name from the list of available devices. Confirm the connection on both devices.

Once successfully connected, your phone's screen is mirrored on your TV. You can launch any video apps (YouTube, KinoPoisk, IVI) - the content will be broadcast without delays.

Disable VPN on your smartphone|

Close background applications that consume internet |

Make sure both devices are connected to the same network (if using Wi-Fi Direct)

-->

⚠️ Note: When using Miracast over Wi-Fi Direct, data transfer speed may decrease if other devices are actively using the same network (for example, a laptop downloading files). For stable 4K streaming, we recommend using a separate 5 GHz network.

3. Method 2: AirPlay for iPhone and Mac

If you have devices Apple (iPhone, iPad or Mac), the most reliable way to stream is AirPlayThe technology works with TVs that support AirPlay 2, or via a set-top box. Apple TV (4th generation and newer).

Step-by-step instructions:

1. Make sure your phone and TV are connected to the same Wi-Fi network (2.4 GHz or 5 GHz).
2. On iPhone, open Control Panel (swipe down from the upper-right corner on iPhone X and later).
3. Click on the icon Screen mirroring (two overlapping rectangles).
4. Select your TV from the list or Apple TVIf prompted, enter the confirmation code that appears on the TV screen.

To broadcast only video (without duplicating the entire screen):

• Open the movie app (for example, Apple TV or YouTube).
• Click on the content transfer icon (usually looks like a rectangle with an arrow pointing up).
• Select the target device.

AirPlay supports streaming up to 4K HDR at 60Hz, but it requires an Apple TV 4K or an AirPlay 2-certified TV (such as 2019 and newer Samsung QLED models).

4. Method 3: DLNA/UPnP for Streaming

DLNA (Digital Living Network Alliance) is a standard for sharing media files between devices on a local network. Unlike Miracast, it doesn't mirror the screen; it only transmits the video file itself. This is convenient for watching movies from your phone's gallery or an external drive.

How to set up:

1. Activate the DLNA server on your TV:
   • For Samsung: Settings → General → External Devices → DLNA Devices
   • For LG: Settings → Network → Home Network → DLNA
5. Install a DLNA app on your smartphone. Popular options:
   • BubbleUPnP (Android)
   • iMediaShare (iOS/Android)
   • LocalCast (Android)

In the application, select the file to broadcast and specify the TV as the output device.

Advantages of DLNA:

• 🎬 Supports almost all video formats (MKV, MP4, AVI).
• 📶 Works even on old TVs (2010–2015).
• 🔄 You can stream content from your phone without blocking its screen.

Flaws:

• ❌ No subtitle synchronization (you will have to download them separately).
• ❌ Sound delay of up to 1–2 seconds (noticeable when watching with external speakers).

How to fix audio lag in DLNA?

Audio lipsyncing when streaming over DLNA occurs due to data buffering. To reduce the effect:

1. In the DLNA app settings on your phone, find the "Audio Delay" parameter and set the value from -200 to +200 ms (selected experimentally).

2. Use a wired connection from the TV to the router (via Ethernet).

3. Switch to a 5GHz network - it provides lower latency than 2.4GHz.

5. Method 4: Manufacturer applications (Smart View, LG TV Plus)

Many brands are developing their own wireless streaming solutions, which are often more stable than universal protocols. Let's look at the most popular ones:

Samsung Smart View
