It's hard to imagine an evening without your favorite movie on the big screen, but what if you don't have an HDMI cable handy and your home router suddenly stops working? Wi-Fi Direct This solution solves this problem by allowing a direct connection between a smartphone and a TV without intermediaries. The technology works on most modern devices, but many users encounter difficulties setting it up: the connection drops, the video lags, or the TV simply doesn't recognize the phone.
In this article, we will cover not only the basic steps of connecting via Wi-Fi Direct, but also nuances that manufacturers rarely mention in the instructions. For example, why Samsung And LG use different protocols for this function, how to bypass restrictions on video formats, and what to do if the transfer speed drops when playing files in 4K HDRYou will also learn what alternatives exist if your TV does not support Wi-Fi Direct — spoiler: there are more of them than it seems.
Before you proceed with setup, please check two key points: firmware version on the TV (updates often add support for new standards) and screen resolution smartphone. For example, on Xiaomi Redmi Note 12 when transferring video to 1080p through Wi-Fi Direct Artifacts may occur if the "Game" mode with a high refresh rate is enabled in the TV settings.
What is Wi-Fi Direct and how does it work on TVs?
Wi-Fi Direct — is a wireless communication standard that allows devices to exchange data directly, without the involvement of a router. Unlike the classic Wi-FiIn a network where all devices are connected to a single access point, the smartphone or tablet itself becomes a "router" for the TV. This is especially convenient when traveling, at the dacha, or when the home network is temporarily unavailable.
Technically Wi-Fi Direct uses the same frequencies (2.4 GHz or 5 GHz), which is normal Wi-Fi, but the connection protocol is simplified. The data transfer speed can reach 250 Mbps (in theory), but in practice it depends on:
- 📱 Smartphone models (chipset, version Android/iOS)
- 📺 TV hardware (processor, RAM size, version WebOS/Tizen)
- 📶 Interference on the air (microwaves, other routers, Bluetooth devices)
- 🎞️ Video format (
MP4is transmitted more easily thanMKVwith multiple audio tracks)
It is important to understand that Wi-Fi Direct ≠ Miracast ≠ DLNA. The first one creates a direct network, the second one duplicates the smartphone screen (as through HDMI), and the third simply streams media files over a local network. For example, on TVs Sony Bravia 2022–2026 Wi-Fi Direct often hidden in the menu Network → Wi-Fi Settings → Direct Connection, whereas Miracast is located in Screen → Screen Mirroring.
⚠️ Attention: On some models LG (for example, series NanoCell 2020–2021) function Wi-Fi Direct is disabled by default. To activate it, you need to hold down the buttonSettingson the remote control for 5 seconds and enter the code0000.

Quality Optimization: How to Avoid Lags and Artifacts
Even if the connection is established, the playback quality may be disappointing. Here's how to improve it:
1. Codec settings
TVs often don't support modern formats like HEVC (H.265) or AV1. Use VLC or Kodi on TV to play "heavy" files. On Android- On smartphones, check the codec using the app before transferring. MediaInfo.
2. Resolution and bitrate
Optimal parameters for Wi-Fi Direct:
- 🎥
1080pat8–12 Mbps— works stably on most devices. - 🎥
4Kat20+ Mbps- only on TVs withWi-Fi 5/6(For example, LG C2, Samsung QN90B).
3. Wi-Fi channel
