Modern users rarely use their TVs exclusively for watching broadcast channels, preferring streaming services and media libraries on mobile devices. However, watching content on a smartphone's small screen can be inconvenient, which is where the ability to mirror images to a larger display comes in handy. For Sony owners, this process is made even easier thanks to the introduction of advanced wireless technologies and integration with the Android TV operating system.
In this article we will examine in detail all the available methods that allow broadcast the screen or content from your gadget to your TV. You'll learn the differences between data transfer protocols such as Miracast, Chromecast, and AirPlay, and get step-by-step instructions for Android and iOS devices. Understanding these nuances will help you avoid common connection errors and enjoy high-definition content without lag.
Before we dive into specific settings, it's worth mentioning that connection stability directly depends on the quality of your home network. If you plan to watch 4K HDR videos, make sure your router supports the standard. 5 GHz, as the 2.4 GHz frequency may not provide sufficient bandwidth to transmit a heavy video stream.
Basic requirements and equipment preparation
The first and most important condition for successful synchronization is that all devices are on the same local network. This means that both your smartphone and Sony TV must be connected to the same router. If you have a dual-band router, make sure both devices are on the same frequency, although modern routers often combine networks under a single SSID.
The second critical issue is keeping the software up-to-date. Sony TVs with Android TV or Google TV operating systems require regular system software updates. Older firmware versions may not work correctly with new encryption protocols or have bugs in the Wi-Fi module, leading to constant connection drops.
⚠️ Attention: If your Sony TV was released before 2015 and runs a proprietary operating system (not Android TV), wireless streaming functionality may be limited to Miracast technology only, and there will be no support for AirPlay 2 or Chromecast built-in.
It's also worth checking your smartphone's power-saving settings. Aggressive battery-saving algorithms can forcefully close background processes responsible for streaming video. Find the battery-related section in your system settings and add streaming apps to the exceptions or allowed background processes list.
☑️ Check before connection
Streaming from Android smartphones to Sony TV
Owners of Android smartphones are at an advantage, as most Sony TVs use the same Android TV or Google TV platform. This ensures native compatibility and minimizes the number of required settings. The primary image streaming method is based on Google Cast technology (Chromecast built-in).
You don't need to install third-party apps to start streaming if you want to stream content from supported services like YouTube, Netflix, or Spotify. Simply open the app on your phone, tap the streaming icon (the rectangle with waves), and select your Sony TV from the list of available devices. The system will automatically find the TV on your local network.
If you need it completely clone the screen To display everything that's happening on your smartphone's screen, including menus and games, the procedure is slightly different. Depending on the smartphone manufacturer (Samsung, Xiaomi, Honor), the function name may vary: Smart View, Broadcast, Wireless Monitor, or Cast.
It's important to note that when cloning your screen, the image quality may be lower than when broadcasting live from an app, as the phone encodes the video stream in real time, putting a strain on the processor.
Why is there no sound when screencasting?
When using full screen cloning (Miracast), audio may be delayed or not transmitted at all due to DRM restrictions or the settings of the Bluetooth headset connected to the phone. The solution is to use live streaming from a video app.
To manually set up the connection through the TV menu, go to Settings → Network & Internet → Reset network settingsIf the devices can't see each other, this action will restart the network modules and often resolve visibility issues.
Using AirPlay 2 on iPhone and iPad
Apple ecosystem users have long been limited in their connectivity options for Sony TVs, but with the release of 2019 and newer models, the situation has changed dramatically. Sony has begun implementing protocol support. AirPlay 2 and HomeKit out of the box. This allows you to stream videos, photos, and music from your iPhone, iPad, or Mac without the need for additional Apple TV boxes.
The setup process is as simple as possible. Make sure AirPlay is enabled on your Sony TV. To do this, press the quick access button on the remote or go to Settings → Apple AirPlay and HomeKitHere you can enable the feature and set an access code if you want to protect your connection from outsiders.
To start casting from your iPhone, open Control Center (swipe down from the upper-right corner on newer models or swipe up on older models). Tap the "Screen Mirroring" icon (two intersecting rectangles) and select your Sony TV. If this is your first time casting, a four-digit code may appear on the TV screen, which you'll need to enter on your smartphone.
⚠️ Attention: When using AirPlay 2, please note that some older routers may not correctly process Bonjour/mDNS broadcast packets required to discover Apple devices. In this case, rebooting the router may help.
AirPlay 2's advantage over standard Miracast is its support for multi-room audio and the ability to control playback directly from the Apple Watch or the Home app. Furthermore, the protocol provides more stable high-resolution video transmission with lower smartphone power consumption.
Sony Video & TV SideView and Google Home apps
Despite the presence of built-in protocols, sometimes it is more convenient to use specialized applications that provide advanced control functionality. Official application Sony Video & TV SideView (or its newer equivalents depending on the region) allows you to not only stream media files from your phone, but also use your smartphone as an advanced remote control with a keyboard for entering text.
For Android users, the most versatile tool remains the app Google HomeIt's preinstalled on most devices and serves as a central hub for smart home control. Google Home lets you not only start streaming, but also control the volume, switch sources, and even turn off your TV.
To use Google Home to cast your screen:
- 📱 Open the Google Home app on your smartphone.
- 📺 Find your Sony TV in the list of devices (it must be linked to a Google account).
- 🖥️ Click on the TV icon and select the "Cast my screen" button.
- ✅ Confirm the action in the pop-up window.
Third-party solutions like AllConnect or BubbleUPnP are also worth mentioning, as they work well with DLNA servers. These apps allow you to stream local video files stored on your phone directly to your TV, bypassing any format limitations that the TV's built-in player may have.
It's important to understand the difference between "casting" and "media streaming" (DLNA). In the former, the phone acts only as a remote control, while the TV downloads the stream from the internet. In the latter, the phone encodes and sends the file, which can result in choppy playback if the Wi-Fi signal is weak.
Comparing Technologies: Miracast, Chromecast, and DLNA
Understanding the myriad of acronyms can be challenging, but understanding the differences between them helps you choose the right connection method for your specific needs. Each technology has its own advantages and limitations, which impact image quality and ease of use.
Below is a comparison table of the main wireless data transmission technologies supported by Sony TVs:
| Technology | Transmission type | Phone addiction | Quality |
|---|---|---|---|
| Miracast | Screen cloning | High (screen should be lit) | Up to 1080p, lags possible |
| Chromecast | Streaming link | Low (you can use your phone) | Up to 4K HDR, stable |
| AirPlay 2 | Streaming (Apple) | Low | Up to 4K HDR, high stability |
| DLNA | File transfer | Average | Depends on the file format |
As the table shows, Chromecast and AirPlay 2 are best for watching online movies, as they don't put a strain on the smartphone's processor. Miracast is ideal for sharing presentations, photos from the gallery, or games that aren't protected from screen recording.
It's worth noting that Miracast technology on Sony TVs is often implemented under the name "Screen Mirroring." In some regions, this feature may be disabled by default and require activation in the network menu.
Troubleshooting and common problems
Even with proper setup, users may encounter issues: the TV doesn't detect the phone, the video stutters, or there's no sound. Most often, the cause lies in the router settings. Make sure AP Isolation isn't enabled on the router. This feature prevents devices on the same Wi-Fi network from communicating with each other, preventing the phone from finding the TV.
If you have a connection but the image quality is poor, try reducing the distance between the router and the TV or switching to a less congested Wi-Fi channel. To check the speed, you can run the built-in network test in your Sony TV settings: Settings → Status → Network → Network Test.
⚠️ Attention: Menu interfaces and item names may vary depending on the Android TV operating system version and the regional model of your Sony TV. If you can't find the option, use the search in the settings (magnifying glass icon).
Another common issue is audio and video desync. This is often resolved by restarting both devices. Unplug the TV for 1-2 minutes (to completely clear the system cache) and restart your smartphone. Also, check if your phone has any Google Play Services system updates.
What should I do if the broadcast is interrupted?
Frequent connection drops may indicate overheating of the Wi-Fi module in your TV or smartphone. Let the device cool down. Also, try setting a static IP address for your TV in your router settings so it doesn't change every time you connect.
If all else fails, you can reset your TV's network settings. This won't delete your apps and accounts, but it will return your network settings to factory defaults, which often resolves software and driver conflicts.
Questions and Answers (FAQ)
Is it possible to screen mirror to an old Sony TV without Android TV?
Yes, if your TV supports Miracast technology (often called Screen Mirroring). However, this isn't possible natively on an iPhone without purchasing an Apple TV adapter or using third-party receiver apps installed on a USB drive (if the TV supports running apps from a USB drive).
Why is the image black and white or distorted when streaming on YouTube?
This may be due to HDR format incompatibility. If your phone is transmitting an HDR10 signal and your Sony TV doesn't support it, or the color setting is incorrect, colors may appear distorted. Try adjusting the color settings in the YouTube app or in your TV's picture settings (Standard or Cinema mode).
Does my Wi-Fi router slow down when streaming 4K video?
Yes, 4K streaming requires high bandwidth (at least 25 Mbps). If other devices are downloading files simultaneously or the signal is weak, buffering and quality degradation may occur. It is recommended to use a router that supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX) and a 5 GHz frequency.
How do I turn off the broadcast if my phone moves to another room?
Typically, it's enough to unlock your smartphone's screen and tap the streaming icon in the app, selecting "Stop streaming." If your phone doesn't respond, you can press the "Input" or "Home" button on your Sony TV remote and select another signal source, which will disconnect.
