• 🔌 Same network: the laptop and TV must be connected to one router (guest network will not work!).

If your TV was released before 2016, check for the presence of the port. HDMI — in this case, an external adapter for 1,500–3,000 ₽ will help (for example, Xiaomi Mi TV Stick or Amazon Fire TV Stick 4K). For laptops on Windows 7 or old ones MacBook You may need to update your network card drivers.

⚠️ Please note: TV manufacturers frequently update firmware, adding or removing support for certain protocols. For example, Samsung deleted in 2023 Miracast Some 2020–2021 models. Before setting up, check the current software version in the TV menu: Settings → Support → Software Update.

2. Method 1: DLNA - simple file transfer without screen mirroring

DLNA (Digital Living Network Alliance) is a standard for sharing multimedia between devices on a local network. Its main advantage: you don't need to mirror your entire laptop screen; you can simply send a video file to your TV. It's suitable for movies in the following formats: .mp4, .mkv, .avi.

How does this work:

1. The laptop acts as DLNA servers (programs like Plex, Kodi or built-in Windows/macOS functions).
2. The TV connects to the server as client and plays the file on its own.

Instructions for Windows 11/10:

1. Open Settings → Network & Internet → Sharing options.
2. Turn on network discovery And file and printer sharing.
3. Install the program Plex Media Server or Serviio (free versions are enough).
4. Add the movie folder to the program library.
5. On your TV, open the app Photo/Video/Media Player (the name depends on the model) and select your laptop from the list of DLNA devices.

For macOS a built-in function will do General access (System Preferences → Sharing → File Sharing) or program Roku Media Player.

The movie folder has been added to the server library.

The laptop and TV are connected to the same Wi-Fi network.

The TV has a DLNA application installed (for example, "Media Player")

Windows/macOS Firewall does not block port 1900 (DLNA)

⚠️ Warning: If the movie does not play, please check codecs on TV. For example, Samsung Tizen does not support AC3 (Dolby Digital) in .mkvSolution: Convert the audio to AAC through HandBrake or enable transcoding in the settings Plex.

3. Method 2: Miracast – Screen Mirroring Without Lag (for Windows and Android)

Miracast - is a wireless screen mirroring technology according to the standard Wi-Fi DirectIt's built in. Windows 8.1/10/11 and the majority Smart TV after 2018. The main advantage: minimal latency (up to 50 ms), which is critical for games or sports broadcasts.

FAQ: Frequently asked questions about streaming movies on TV

Is it possible to stream a movie from a laptop to a TV without Wi-Fi?

Yes, there are three options:

1. Use HDMI cable (you need a corresponding port on your laptop).
2. Connect via Wi-Fi Direct (if supported by TV and laptop).
3. Use Ethernet adapter (For example, TP-Link UE300) for wired connection.

Network-free methods like Bluetooth not suitable for video due to low data transfer rate.

Why is there no sound on the TV when streaming from a laptop?

The reasons may be different:

• 🔇 The wrong audio output is selected in the player on the laptop (for example, HDMI instead of Wi-Fi).
• 🔇 The TV does not support the audio format (for example, DTS V .mkv).
• 🔇 In the settings Windows sound is disabled for wireless devices (Settings → System → Sound).

Solution: Check the audio settings on both devices and convert the audio track to AAC.

How do I stream a movie from my laptop to my TV if my router doesn't support 5 GHz?

In this case:

1. Use DLNA instead of Miracast (it also works on 2.4 GHz).
2. Reduce video resolution to 720p (to reduce the load on the network).
3. Connect your laptop to the router via cable (Ethernet), and leave the TV on Wi-Fi.

If lags persist, consider purchasing an inexpensive router with 5 GHz support (for example, TP-Link Archer C6 for 2,000 ₽).

Is it possible to stream online cinemas (Kinopoisk, Netflix) from a laptop to a TV?

Yes, but there are some nuances:

• 🎥 Through Miracast/AirPlay — you can duplicate the entire screen, but there may be lags.
• 🎥 Through Chromecast - only official applications are supported (for example, Netflix or YouTube have a built-in broadcast button).
• 🎥 Through DLNA — it won’t work, since online content is not a local file.

Best option: Install the cinema app directly on Smart TV (if it is available in the app store).

How to improve Wi-Fi streaming quality?

Follow these guidelines:

• 📶 Switch your router to a different range 5 GHz (less congested, higher speed).
• 📶 Reduce the distance between the router and devices (ideally up to 3 meters).
• 📶 Disconnect other devices from the network (smartphones, tablets) to free up the channel.
• 📶 In the router settings, select a channel with minimal interference (use the app Wi-Fi Analyzer).

If your router is old, consider replacing it with a model that supports Wi-Fi 6 (For example, ASUS RT-AX55).
