How to stream video to a Smart TV via Wi-Fi from your phone: all the working methods

Stream video from your phone to the big screen Smart TV through Wi-Fi — a task that almost every user faces. Do you want to show your friends a vacation video, play a movie from your phone on your TV, or stream from YouTube Without unnecessary wires? There are at least five ways to do this, but not all of them are equally convenient. Transfer speed, format support, and even the TV model can play a decisive role.

In this article we will look at all current methods — from standard protocols like DLNA And Miracast to proprietary solutions such as Google Cast or Apple AirPlayYou'll learn which method is the fastest, which works offline, and how to avoid common errors like "device not found" or stream interruptions. And also— Why on some TVs Samsung And LG 2020–2022 releases may not have a live broadcast iPhone without additional applications.

1. Preparation: What to check before submitting a video

Before attempting to transfer video, make sure your devices are ready for it. Errors at this stage account for 70% of failed attempts.

Network requirements:

• 📶 One Wi-Fi network. The phone and TV must be connected to the same router. Exception: Miracast (works without a router, but with limitations).
• 🔄 Stable signal. To transfer video to 4K speed required is not less than 25 MbpsCheck the speed on your phone via Speedtest.
• 🔒 No blocking. Some routers (especially office ones) block protocols DLNA or MulticastIf the video isn't streaming, check your firewall settings.

Device requirements:

• 📺 Smart TV with Wi-Fi Direct or DLNA support. Most models Samsung (series Q, CU), LG (With webOS 4.0+), Sony Bravia And Xiaomi TV Support these protocols. Check your TV's manual for details.
• 📱 Smartphone running Android 5.0+ or ​​iOS 12+. Older versions may not have the features you need (for example, Google Cast on Android 4.4 works with errors).

What to do if the TV doesn’t see the phone?

• ⚙️ Restart both devices.
• 🔄 Turn on the "Visible to other devices" mode in the TV's Wi-Fi settings (usually in the Network → Wi-Fi Direct).
• 📱 On Android check if it is turned on Miracast (Settings → Connected devices → Screen sharing). On iPhone — Control Center → Screen Mirroring.

⚠️ Attention: On TVs Samsung 2018–2019 (series NU, RU) a firmware update may be required to work correctly with iPhoneCheck the software version in the menu Support → Software Update.

2. Method 1: DLNA is a universal protocol for local area networks

DLNA (Digital Living Network Alliance) is a standard that allows devices on the same network to exchange media files. Key benefits: no need to install additional applications to the TV (if it supports DLNA out of the box).

How does this work:

1. The phone and TV are connected to the same Wi-Fi.
2. It starts on the phone DLNA server (built-in or via app).
3. The TV scans the network and finds the phone as a media source.
4. Select a video on your phone and it will play on your TV.

Instructions for Android:

1. Install the application BubbleUPnP (free) or LocalCast.
2. Open the app, select a video from your gallery.
3. Click Play on and select your TV from the list.

Instructions for iPhone:

1. Install 8player Lite or nPlayer.
2. In the application settings, enable DLNA server.
3. Select a video and send it to your TV.

Phone and TV on the same Wi-Fi network

DLNA is enabled on the TV (in the network settings)

The phone has a DLNA application installed

Video in supported format (MP4 recommended)

VPN is disabled on the phone (it may block multicast)

-->

⚠️ Attention: If the video is lagging or choppy, try reducing the bitrate. To do this, use the app BubbleUPnP select Settings → Transcoding → Limit bitrate to 10 Mbps.

3. Method 2: Miracast – Screen Mirroring Without a Router

Miracast - wireless screen mirroring technology that works without a router (directly between the phone and the TV). This is the only way to transfer video if you don't have Wi-Fi, but you do have Smart TV with support Wi-Fi Direct.

Pros:

• ✅ No router dependency.
• ✅ Minimal lag (suitable for gaming).
• ✅ Works on everyone Android-devices with version 4.2+.

Cons:

• ❌ Doesn't work with iPhone (Apple uses AirPlay).
• ❌ Maximum resolution - 1080p (even if the TV supports 4K).
• ❌ Artifacts are possible with a weak signal.

How to enable Miracast on Android:

1. Open Settings → Connected devices → Screen sharing (on Samsung: Settings → Connections → Screen Mirroring).
2. Enable device search.
3. Activate on TV Wi-Fi Direct or Screen Mirroring (usually on the menu Network → Miracast).
4. Select your TV from the list on your phone.

Compatible TVs:

• 📺 Samsung (all models with Tizen OS, starting from 2016).
• 📺 LG (With webOS 3.0+, series OLED And NanoCell).

• 📶 Bring your phone closer to the TV (ideally within 3 meters).
• 🔋 Turn off power saving mode on your phone.
• 🔄 If the image is lagging, reduce the phone's screen resolution in the display settings.

4. Method 3: Google Cast (Chromecast) - for Android and iPhone

Google Cast — a technology that allows you to “send” video from your phone to your TV through applications that support this function (for example, YouTube, Netflix, Google Photos). Unlike DLNAHere the video is streamed directly from the Internet, and the phone is used only as a remote control.

How does this work:

1. The TV and phone are connected to the same Wi-Fi network.
2. It's on the TV. Google Cast (built-in or via device Chromecast).
3. In a supported application (eg. YouTube) press the “Broadcast” button and select the TV.

Which TVs support Google Cast?

• 📺 All Android TV (Sony Bravia, Philips, Xiaomi, Nvidia Shield).
• 📺 Samsung (only models with Google Play Store, starting from 2020).

• ❌ Quality depends on internet speed (even for local files).

⚠️ Attention: On TVs Samsung With Tizen (until 2020) Google Cast may work unstable. In this case, use Smart View (proprietary solution from Samsung).

5. Method 4: Proprietary solutions (Smart View, AirPlay, Xiaomi Screen Mirroring)

TV manufacturers often develop their own video transmission protocols. These may be more convenient than universal solutions, but they only work with devices within the same ecosystem.

8. Typical problems and their solutions

Even if you've done everything correctly, errors can still occur. Here are the most common ones and how to fix them:

Problem 1: The TV doesn't detect the phone

• 🔄 Restart your router, phone, and TV.
• 📶 Check that both devices are on the same network (sometimes the phone is connected to 5 GHz, and TV - to 2.4 GHz).
• 🔒 Disable VPN or firewall on your phone.

Problem 2: Video stutters or cuts out

• 📉 Reduce the video resolution (for example, from 4K to 1080p).
• 🔌 Connect your phone to a charger (power saving mode may limit Wi-Fi performance).
• 📡 Switch the router to a different channel 5 GHz (less busy).

Problem 3: No sound during transmission

• 🔊 Check if the sound on your TV or phone is muted.
• 🎧 If you use Miracast, try enabling "Sound transmission" in the connection settings.
• 🔄 Reconnect your devices.

Problem 4: Video format not supported

• 🎞️ Convert video to MP4 (codecs H.264 or H.265) through HandBrake or VLC.
• 📱 Use transcoding apps (eg. BubbleUPnP can convert "on the fly").

Problem 5: iPhone doesn't transfer to Samsung/LG

• 🍎 Install the application TV Cast or ApowerMirror.
• 🔄 Turn on the “Screen Mirroring” mode on your TV (Samsung) or "AirPlay" (LG).

Why is there no sound on some TVs when using Miracast?

The reason is that Miracast transmits sound using the protocol A2DP, which not all TVs support correctly. Solutions:

1. Connect external speakers to the TV.

2. Use DLNA instead of Miracast.

3. Update your TV firmware (new versions often fix this error).
