Before you start transferring files, make sure your TV and computer are are on the same Wi-Fi networkThis is a key requirement for all methods except cloud services. You can check the connection as follows:

• 📺 On TV: go to Settings → Network → Network Status (The path may vary depending on the model). Remember the network name (SSID) and IP address.
• 💻 On your computer: In Windows, open Settings → Network and Internet → Wi-FiOn macOS, click the Wi-Fi icon in the menu bar.
• 🔄 If the networks are different, connect both devices to the same router. Use 2.4 GHz for greater stability or 5 GHz for high speed (if both devices support it).

Also check if your TV supports the required protocols:

* SMB speed depends on the capabilities of the router and the protocol version (for example, SMB 3.1.1 faster SMB 1.0).

⚠️ Attention: If your TV was released before 2018, it may not support modern protocols like Miracast or Google CastIn this case, use DLNA or connect an external adapter (for example, Chromecast or Fire TV Stick).

3. Method 2: Miracast (Screen Mirroring) – screen mirroring

Miracast It allows you to not only transfer files but also fully mirror your computer screen to your TV. This is convenient for presentations, game streaming, or viewing content that isn't directly supported by your TV (for example, .mkv with rare codecs).

How to connect:

• 🖥️ On Windows: click Win + K, select your TV from the list. If it's not there, check if your PC supports it. Miracast (enter in command line dxdiag, then find the line Miracast in the section System).

• 📺 On TV: turn on Screen Mirroring (at Samsung), Smart Share (at LG) or Mirroring (at Sony).

Miracast Limitations:

• ⚠️ Latency up to 100 ms - not suitable for dynamic games.
• ⚠️ The screen resolution may automatically decrease to 1080p, even if the TV supports 4K.
• ⚠️ On some laptops (especially with Intel UHD Graphics) Miracast is unstable.

4. Method 3: Cloud services - for any files without settings

If your TV has internet access, the easiest way to transfer files is to upload them to the cloud and view them on your TV. This method works even if the devices are on different networks (for example, if you're at a cafe and your TV is at home).

Suitable services:

• 🌥️ Google Drive: supported on Android TV and TVs with Google PlayThe maximum file size is 5 TB.
• 🌥️ Dropbox: there is an application for Samsung Tizen And LG webOSFree - up to 2 GB.

5. Method 4: SMB (Samba) - for large files and folders

SMB (Server Message Block) is a protocol for sharing files on a local network. It allows for the transfer of files of any size and is faster than DLNA. However, to use it, you need to configure network drive on your computer and connect to it from your TV.

How to set up SMB on Windows:

1. Open Control Panel → Programs → Turn Windows features on or off.
2. Activate Support for SMB 1.0/CIFS file sharing (only if the TV is old) or SMB Direct (for modern devices).
3. IN Conductor Right-click on the folder you want to open for TV, select Properties → Access → Share.
4. Set your username and password (eg. TV_User And 12345).

How to connect from TV:

• 📺 LG webOS: Settings → Network → Network-Attached Storage (NAS) → Add Device. Enter the IP address of the computer (you can find it through ipconfig on the command line) and login information.
• 📺 Sony Bravia: Settings → Network → Home Network → Servers → Add Server.
• 📺 Xiaomi: use the app File Manager, select LAN → Add SMB.

Benefits of SMB:

• ✅ Transfer speed up to 1 Gbps (if the router supports it).
• ✅ No file size limit.
• ✅ You can mount it as a network drive and work with files directly.

6. Method 5: Specialized applications (Plex, Kodi, VLC)

If built-in methods don't work or you need additional features (such as on-the-fly video transcoding), use third-party apps. They support more formats and often offer a user-friendly interface.

2. Add folders with files to your Plex library.
3. Install the application Plex on the TV and log in to the same account.
4. Select the server (your computer) and play the file.

⚠️ Attention: When using Plex or Kodi for playback 4K HDR video, make sure your TV supports it HEVC (H.265) And 10-bit colorOtherwise, the image may be displayed with artifacts.

7. Troubleshooting: The TV doesn't see the computer

If none of the methods work, check the following points:

Problem 1: The devices do not see each other on the network.

• 🔌 Make sure that the router is turned on DHCP (automatic IP distribution).
• 🔄 Reboot the router and both devices.
• 🛡️ Disable the firewall on your computer (Control Panel → Windows Firewall → Turn on or off).

Problem 2: Files do not play on TV.

• 🎬 Check your TV manual for supported formats. For example, Samsung Tizen does not reproduce .avi with codec DivX.
• 🔧 Convert files to .mp4 with codec H.264 through HandBrake or FFmpeg.
• 📁 If the file is large, try splitting it into parts (for example, using 7-Zip).

Problem 3: Low transfer speed.

• 📶 Switch to range 5 GHz (if the router is dual-band).
• 🔌 Connect your computer to the router with a cable (Ethernet).
• 📡 Change the Wi-Fi channel in the router settings (use NetSpot to analyze channel congestion).

FAQ: Frequently Asked Questions

Is it possible to stream files from a Mac to a TV via Wi-Fi?

Yes, but standard methods (such as DLNA) work worse on macOS than on Windows. Use:

• Infuse - application for Apple TV And Android TV, supports SMB.

Why does video lag when playing on a computer?

Reasons and solutions:

• Slow Wi-Fi speed: switch to 5 GHz or use a cable.
• Unsupported codec: convert video to H.264 or H.265.
• Weak TV processor: use Plex with transcoding (will reduce the load on the TV).

How to transfer a file larger than 4GB?

If DLNA does not support large files:

1. Use SMB (see method 4).
