Modern Smart TVs from the company Sony offer a variety of ways to interact with mobile devices, but it is the technology WiFi Direct remains one of the most popular and often misunderstood tools. Unlike a traditional home network connection via a router, this method allows for a direct connection between a TV and a smartphone or tablet, without intermediaries. This creates a separate communication channel, ideal for quickly streaming multimedia content when the router is overloaded or located far away.
Many users confuse this function with the usual DLNA or Chromecast, but the operating principle is fundamentally different. When activated, the TV essentially turns into an access point to which an external device can connect. This ensures a more stable high-definition video stream, as the data doesn't pass through the router, creating a direct path between the screen and the signal source. Understanding these nuances will help you avoid common setup mistakes.
It's important to note that using this protocol doesn't always require internet access. If you simply want to stream photos from your gallery or play a video saved on your phone, an external network isn't required. However, streaming services like YouTube or Netflix through the TV's built-in apps still require internet access, but it can be supplied to the TV via cable while the mobile device is using its own data plan or is in airplane mode.
Technical features and operating principle of the protocol
Fundamental difference WiFi Direct The difference from standard Wi-Fi lies in the connection architecture. In a typical situation, all devices communicate through a central hub—a router. In this case, the TV Sony Bravia or Android TV It acts as a software access point (SoftAP). This means the device generates its own network name (SSID) and password, which you connect to from your smartphone, just like a regular home router.
This one-to-one or one-to-many topology allows for high data transfer rates, which is critical for Screen Mirroring (Screen mirroring). When you mirror your image, the video stream is transmitted in real time with minimal latency. The protocol uses WPA2 encryption standards, so the connection is protected from unauthorized access if you set a strong password in your TV settings.
Why might the speed drop?
Data transfer speeds may decrease if there are many other networks operating on the same frequency. The protocol automatically switches channels, but in apartment buildings with dozens of routers, interference is possible. Speed also depends on the Wi-Fi standard (n, ac, or ax) supported by both devices.
It's worth keeping in mind that when a connection is active, a mobile device often switches to using cellular data for internet access, as the WiFi module is busy connecting to the TV. Some modern smartphones can simultaneously maintain a connection to both a router and a TV, but this depends on the specific phone model and operating system version. Android or iOS.
Step-by-step activation of the feature on Sony TVs
The process of enabling the mode may differ slightly depending on the operating system of your TV: Android TV or proprietary shell Sony LinuxIn most modern models with Android TV You need to go to the main menu and find the settings section. Users often look for a separate app, but the function is deeply embedded in the system network settings.
Click the button Menu or Settings on the remote control. Follow the path Settings → Network & Internet → WiFi DirectIn some firmware versions, this item may be located in the section Applications or ConnectionsOnce you enter the menu, you will see a status switch. Set it to the on position. On (On). The TV will start searching for available frequencies and entering preparation mode.
☑️ Check before connection
Once activated, the network name (SSID) and password will appear on the screen. This information may be hidden by default. To view it, press the button. Options on the remote or select "Manual Mode" / "Show SSID." Write down or take a photo of this information, as you will need it for pairing. If the TV prompts you to select "Normal" or "PIN Code" mode, it's best to select this for the first connection. Normalto simply accept the request on the screen.
Instructions for connecting smartphones and tablets
Once the TV is ready for use, you need to set up your mobile device. For owners of smartphones based on Android The process is generally standardized, although menu names may vary between manufacturers (Samsung, Xiaomi, Honor). Open the WiFi settings and start scanning for available networks. You should see your TV's name in the list. Sony, which you saw in the previous step.
Click on the network name. The system will ask for the password (WPA Key), which is displayed on the TV screen. Enter it carefully, observing the capitalization. After successful authentication, your phone may warn you that "The Internet is not connected." This is normal, as you are connected locally. Confirm the connection. Now the devices can "see" each other.
For device users Apple (iPhone, iPad) the situation is different. Technology WiFi Direct iOS doesn't natively support screen mirroring the way Android does. Apple uses its own protocol. AirPlayHowever, if your Sony TV has an operating system installed Android TV With AirPlay 2 support, you can use the standard Screen Mirroring feature in the iPhone's Control Center by selecting the TV from the list, without having to connect to the TV's WiFi network.
If automatic connection does not occur, you can use the WPS method. On the TV screen, select the option WPS Push or WPS PINIn your phone's WiFi settings, press the WPS button (if there's a physical or software button) or enter the PIN code from your TV. This simplifies entering long passwords and speeds up the pairing process.
⚠️ Attention: When connecting to WiFi Direct, your phone may temporarily lose WiFi internet access and switch to a mobile network. If the streaming app requires internet access, make sure mobile data is enabled, or use "Access Point" mode on the second phone if this is critical.
Using Screen Mirroring and Media Transfer
Once the connection is successfully established, the content transfer phase begins. Screen mirroring on Android often requires launching a system function. This may be called "Cast," "Smart View" (on Samsung), "Wireless Projector" (on Xiaomi), or "Cast." When you start searching, the phone will find the TV. Sony and will offer to connect.
A request to allow the connection will appear on the TV screen. Use the remote control to select Accept (Accept). From now on, the image from your phone will be cast to the big screen. This is convenient for watching videos from file managers that don't support Chromecast, or for sharing presentations and photos.

| Function | Description | Requirements |
|---|---|---|
| Screen Mirroring | Full mirroring of your smartphone screen | Miracast support by both devices |
| DLNA | Transfer photos/videos from the gallery | Both devices are on the same WiFi network |
| Chromecast built-in | Streaming content from apps | Both devices are on the same WiFi network |
| AirPlay 2 | Broadcasting from Apple devices | TV with AirPlay support, iOS 12+ |
It's important to understand the difference between screen mirroring and streaming. When mirroring, the phone acts as a video source, its screen remains lit, and the battery drains faster. When streaming (for example, via YouTube), the phone acts only as a remote control, and the video is downloaded directly from the internet by the TV, which saves battery life and reduces bandwidth usage.
Diagnosing problems and troubleshooting connection errors
Despite the simplicity of the technology, users often encounter problems. One of the most common is that the TV isn't visible in the list of available networks or devices. In this case, the first thing to do is check whether the "Hidden SSID" mode is enabled on the TV. If it is, you'll have to add the network manually, entering the exact name and password.
Another common issue is constant connection drops or poor image quality (artifacts, lag). This is often due to congestion in the 2.4 GHz band. If your router and TV operate on this frequency and there are many neighboring networks nearby, interference can occur. In the WiFi Direct settings on your TV Sony You can try changing the channel or frequency to 5 GHz if your equipment supports this standard.
What should I do if the connection request does not appear?
Sometimes the Android TV system gets stuck waiting. Try selecting "Remove Device" for your phone in the WiFi Direct menu on your TV, then reboot the TV. This will clear the network services cache.
You should also check the antivirus programs or firewalls on the connected laptop or tablet. They may block incoming connections from the TV, considering them potentially dangerous. Temporarily disable the protection to check or add the TV to the list of trusted devices.
⚠️ Attention: The menu interface and item names may change after updating your TV's firmware. If you can't find the settings described above, consult the official user manual for your specific model on the Sony support website, as the layout of the items varies depending on your operating system version.
Comparison with alternative translation methods
Why is it worth using? WiFi DirectIf you have a Chromecast or HDMI cable, what's the best way to stream? The main advantage is its versatility and lack of infrastructure. You don't need a router or a shared network, making this method ideal for hotels, office meeting rooms, or cottages where internet access is unavailable.
However, this method has its drawbacks. Unlike Chromecast, which allows you to control playback from your phone and turn off the screen, WiFi Direct (in Mirroring mode) requires the phone's screen to be active. This results in high power consumption. Furthermore, latency with wireless screen mirroring is higher than with a wired connection, so playing fast-paced games this way can be uncomfortable.
For viewing photos and videos from your phone's local storage, WiFi Direct is an excellent solution, as it provides direct data transfer without the compression sometimes used when streaming via cloud services. Image quality remains intact, with no loss of detail.
Why can't my Sony TV see my phone?
Make sure your phone's Wi-Fi is enabled and isn't in "Moderation" or "Data Saver" mode, which can block device detection. Also, check that your TV hasn't reached its maximum number of connected devices (usually 10).
Can I play games on my TV using WiFi Direct?
Technically possible, but not recommended. Input lag during wireless screen mirroring ranges from 50 to 150 ms, making shooters and racing games unplayable. For gaming, it's better to use an HDMI cable or built-in Smart TV games.
Does the TV use the Internet from the phone when connected via WiFi Direct?
No. WiFi Direct creates a local network only for media streaming. To access the internet on your TV (for example, online movie theaters or a browser), it will need a separate connection to the router via WiFi or a LAN cable.
How do I disable the confirmation prompt on my TV?
You can change the registration mode in the WiFi Direct settings on your Sony TV. Select "Automatic" instead of "Manual" or "PIN" so that previously connected devices can connect without your intervention.
Does WiFi Direct affect home internet speed?
No, since the connection is direct between devices, bypassing the router. However, if your phone uses the same antenna for internet distribution and TV connection (which is rare, but possible in some implementations), speed may drop. In the typical scenario, your home internet connection is unaffected.
