A modern television receiver is no longer just a device for receiving over-the-air channels, but has become a fully-fledged multimedia center that requires constant data exchange with the outside world. One of the key technologies that enables wireless content transmission from mobile devices to a large screen without the use of a router is WiFi DirectThis feature allows you to create a direct connection between your smartphone and TV, which is especially useful in situations where your home network is overloaded or there is no internet access.
Users often wonder which specific models and brands implement this feature, as there is no universal standard for all devices. Some manufacturers implement the technology by default across their entire product line, while others reserve it for flagship models or replace it with proprietary alternatives. Understanding the differences between Miracast, AirPlay and native WiFi Direct will help you choose the optimal device for streaming photos and videos.
In this article, we'll take a detailed look at the list of manufacturers that support this technology and explore the nuances of setting up a connection on different operating systems. You'll learn how to activate broadcast mode, why your smartphone might not recognize your TV, and what alternative methods exist for older models. WiFi Direct technology operates on 2.4 GHz and 5 GHz frequencies, providing high data transfer speeds without the delays typical of Bluetooth.
List of manufacturers and technology support
Market analysis shows that the vast majority of modern TVs released after 2015 are equipped with a wireless module supporting direct connections. However, implementation of this feature may vary depending on the operating system installed and brand policy. Companies using open platforms such as Android TV and webOS traditionally lead the way in this area.
Company Samsung introduced support for the technology into its Smart TVs quite early, but often disguises it under names like "Screen Mirroring" or "Smart View." Devices LG WebOS-based models also have a built-in module that activates automatically when attempting to connect a new device. However, budget models from Chinese brands may require manual activation via the engineering menu or installation of additional software.
Below is a list of the main brands whose products are guaranteed to support the protocol:
- 📺 Samsung — Smart TV series with Tizen OS (models J, K, M, N, Q, R series and newer).
- 🌐 LG — all TVs with the webOS platform (since 2014).
- 🤖 Sony — models based on Android TV and Google TV.
- 📱 Xiaomi / Mi — almost all models with Android TV, including budget lines.
- 🔵 Philips — devices with the Android TV operating system.
⚠️ Attention: In some TV models Hisense And TCL The feature may be hidden in the "Applications" section under the name "Anyview Cast" or "T-Cast" rather than in the main network settings.
Differences between WiFi Direct and Miracast
Users often confuse these two concepts, considering them synonyms, but technically they are different levels of wireless transmission implementation. WiFi Direct — is a standard that allows devices to connect to each other directly without an access point, creating their own network. Miracast — is a protocol that uses the WiFi Direct infrastructure to transmit video and audio in real time.
Simply put, WiFi Direct is the "pipe" through which data travels, and Miracast is the "water" that flows through it. Just because your TV supports WiFi Direct doesn't guarantee it will be able to mirror your Android smartphone's screen using the "Cast" feature. This requires support for the Miracast protocol or its equivalent.
Apple devices use their own standard called AirPlay, which also works over wireless connections, but requires a compatible receiver or an emulator app installed on the TV. iPhone owners should look for the "Works with Apple AirPlay" logo or built-in support on their Smart TV.
Can WiFi Direct be used for gaming?
Yes, it's possible, but with limitations. The protocol provides low enough latency to play turn-based strategy games or card games. However, for fast-paced shooters, a latency of 100-200 ms can be critical. For gaming, it's better to use a wired connection or specialized gaming modes with low input lag.
Setting up a connection on Samsung TVs
On TVs from the South Korean giant, the activation process is often automated but requires confirmation via the remote control. To start streaming, you need to ensure that the signal reception function is enabled in the device menu. On newer Tizen OS models, this is done via the quick access panel.
Click the button Home On the remote, go to the menu on the left and select "Source" or "Connect to a mobile device." If you're using an older model, the path may be different: Settings → Network → Screen CastingMake sure the switch is in the "On" position.
Once activated, the TV will begin searching for available devices or become visible to smartphones. When connecting for the first time, a permission request may appear on the TV screen; you must confirm this within 30 seconds.
☑️ Check before connecting Samsung
It's important to note that in some regions, firmware may have limitations on certain video codecs when streaming. If the image is choppy, try lowering the quality of the streaming content on the source.
Features of LG webOS and Sony Android TV
Televisions LG WebOS devices are renowned for their user-friendly interface. The feature is called "Screen Share." To launch it, simply press the house or gear button on the Magic Remote and select the corresponding icon in the bottom bar of the launcher.
Unlike Samsung, LG often requires the installation of a proprietary application LG TV Plus to a smartphone for full control, although basic screen sharing also works through standard Android tools. On TVs Sony On Android TV, settings are on the way Settings → Network & Internet → Screen Mirroring.
Sony devices also support the protocol Chromecast built-in, which allows you to stream content from YouTube, Netflix, and other apps directly, bypassing your smartphone's screen. This saves battery life and reduces the load on your WiFi network.
Compatibility and frequency range table
When choosing a TV, it's important to consider not only the module's availability but also the supported frequencies. Older models can only operate in the 2.4 GHz band, which can lead to interference and connection drops in the presence of multiple neighboring networks. Modern standards support 5 GHz for transmitting high-definition 4K video.
| Brand | operating system | Function name | 5 GHz support |
|---|---|---|---|
| Samsung | Tizen | Smart View | Yes (2018+ models) |
| LG | webOS | Screen Share | Yes (2017+ models) |
| Sony | Android TV | Broadcast | Yes (in all 4K models) |
| Xiaomi | Android TV | Cast | Yes (in models from 2019) |
As the table shows, support for high-speed frequencies has become standard for 4K TVs. If you plan to stream large video files with bitrates above 20 Mbps, 5 GHz is critical for stability.
Troubleshooting connection issues
Even with all the necessary technologies in place, users may encounter a situation where devices cannot see each other. Most often, the problem lies in the router's security settings, even when using a direct connection. Some antivirus software on smartphones can block attempts to create a local network.
Try restarting both devices: unplug the TV for 1 minute (to clear the network cache) and restart your smartphone. Also, make sure that "Data Saver" or "Airplane Mode" aren't enabled on your phone, as these can block the Wi-Fi module.
If all else fails, check the date and time on your TV. A time misalignment of more than 5 minutes can cause security certificate errors when devices handshake using the WPA2 protocol.
⚠️ Note: Menu interfaces and item names may change after updating your TV's firmware. If you don't find the item you're looking for, search for "Direct," "Mirror," or "Screen" in the settings.
Alternatives for older TV models
If your TV doesn't have built-in Smart TV or WiFi Direct support, that doesn't mean you can't stream content. There are a variety of external devices that can add this functionality to any screen with an HDMI port. The simplest solution is to purchase a WiFi receiver or set-top box.
Devices like these are popular Google Chromecast, Amazon Fire TV Stick or Apple TVThey connect to the HDMI port and handle all the signal reception and video decoding. There are also special dongles that emulate a Miracast receiver.
For owners of older TVs with good picture quality, these set-top boxes are a great way to extend the life of their device, adding modern Smart TV functionality at a fraction of the cost. Installation typically takes no more than 5 minutes and requires no special skills.
Is internet required for WiFi Direct to work?
No, internet access is not required to create a direct connection between your phone and TV. The devices create their own local network. However, if you want to stream online video from an app on your phone, internet access is required on your smartphone.
Does WiFi Direct affect internet speed in a room?
Since the connection is direct (device-to-device), it doesn't put a strain on your main router. However, the phone's WiFi module may switch between networks, which can cause a temporary internet connection interruption on the smartphone itself during active streaming.
Is it possible to connect to a TV from a laptop?
Yes, most Miracast-enabled TVs allow you to connect not only smartphones but also Windows 10/11 laptops. To do this, use the keyboard shortcut Win+K and select your TV from the list of available displays.
Why does the video lag during broadcasting?
Most often, the cause is a weak signal or congestion on the 2.4 GHz channel. Try moving closer to the TV or switching your router (if you're using a hybrid connection) to the 5 GHz channel. Closing background apps on your phone can also improve performance.
