For a successful wireless connection, it's crucial that both devices are on the same local network. This is a basic requirement, without which device discovery is impossible. Below, we'll cover the technical details of setup, potential issues, and solutions for various Sony TV models.
Technical requirements and equipment preparation
Before you begin setup, you need to make sure your equipment meets the minimum technical requirements for wireless data transmission. TVs Sony, released after 2014, as a rule, already have a built-in module Wi-Fi Direct and Miracast support. However, for Smart TV features like Chromecast built-in to work, the device must be connected to the internet.
The speed and stability of your wireless connection directly impacts the quality of the streamed image. If you plan to watch videos in HD resolution 4K HDR, it is recommended to use the frequency range 5 GHz, which provides higher throughput compared to the standard 2.4 GHzThis is especially important in the noisy airwaves of apartment buildings.
Make sure your TV's software is updated to the latest version. Manufacturers regularly release patches that improve network module stability and compatibility with new mobile OS versions. You can check this through the system settings menu.
⚠️ Note: Some older router models may not correctly process multicast traffic, which is necessary for discovering devices on the network. If your TV doesn't detect your phone, try temporarily disabling the "AP Isolation" feature in your router settings.
Setting up Screen Mirroring for Android devices
Function Screen Mirroring (screen mirroring) is native to most Android smartphones and does not require additional software. TVs Sony Miracast uses the Miracast protocol to implement this feature, which allows for a direct connection between devices. To get started, press the button on the remote control.

It's worth noting that when mirroring, the smartphone's screen may remain dimmed, which can increase battery consumption. Furthermore, the image format will strictly match the phone's aspect ratio, so black bars may appear on the sides if the content isn't widescreen-ready.
Using Google Cast (Chromecast built-in)
Most modern televisions Sony work on the basis of the Android TV or Google TV operating system, which means that the presence of built-in technology Google CastUnlike mirroring, this method streams content directly from the internet to the TV, using the phone only as a remote control. This frees up the smartphone for other tasks and saves battery life.
For this method to work, both devices must be connected to the same Wi-Fi network. Open an app that supports casting, such as YouTube, Netflix or Google PhotosFind the broadcast icon—the rectangle with waves in the corner—and tap it.
In the list that appears, select your TV. SonyThe video will start playing on the big screen, and controls will appear on your phone: pause, rewind, and volume. Image quality is often higher in this case, as the TV decodes the video stream itself using its powerful processors.

|---|---|---|
| Transmission type | Screen mirroring | Stream broadcast |
| Phone CPU usage | High | Low |
| Ability to turn off the screen | No | Yes |
| Internet addiction on TV | Not required (Direct) | Required |
What should I do if the Cast icon doesn't appear?

Besides mirroring the entire screen, many applications such as Apple TV+, Vimeo or Netflix, have their own AirPlay button within the interface. This is the preferred viewing method, as it allows you to use your phone for other tasks while watching a movie.
Solution and troubleshooting
Despite proven technologies, users may encounter situations where their phone doesn't detect the TV or the connection constantly drops. Most often, the problem stems from a simple out-of-sync network setting. First, try rebooting your router, TV, and smartphone—this resolves up to 80% of connection issues.
If the devices can see each other but data transfer isn't working, check the date and time on both devices. A time stamp mismatch can block the secure connection required for DRM-protected content (movies, TV shows). Also, make sure your TV has the latest firmware version installed via the menu. Settings → About TV → System Update.
In some cases, antivirus software on your computer or phone, as well as firewall settings, can block local device detection. Try temporarily disabling protection or adding your TV to the exceptions list. It's also worth checking whether "Data Saver" mode is enabled on your mobile device, which can limit background network activity.
Alternative connection methods and applications
If standard methods don't work or you need advanced features, you can use third-party apps. Official app Video & TV SideView Sony's Smart TV not only lets you stream content but also use your smartphone as an advanced keyboard for text entry and playback control.

Why can't my Sony TV see my phone?
Most often, the devices are on different networks (for example, one is connected to 2.4 GHz and the other to 5 GHz, and the router is isolating them). It's also possible that the Screen Mirroring app isn't running on the TV, or that Wi-Fi power-saving mode is enabled.
Is it possible to connect a phone to a TV without the Internet?
Yes, Wi-Fi Direct (Screen Mirroring) doesn't require internet access; it creates a direct connection between devices. However, Google Cast or AirPlay typically require internet access, at least for the initial handshake.
How to improve picture quality during wireless broadcasting?
Use a router that supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX). Place the router and TV within direct line of sight, or connect the TV to the router via a LAN cable while keeping your phone connected to Wi-Fi.
Is it safe to connect my personal phone to public Wi-Fi for streaming?
Broadcasting is impossible on public networks with client isolation enabled. If the network is open, data transmission can be intercepted. It is recommended to use only trusted home networks or create a hotspot on the phone itself if the TV supports it.
