Modern Smart TVs from the brand BQ opens up a wide range of multimedia interaction options for users, allowing them to stream content from mobile devices directly to the big screen.
The process of synchronizing a smartphone and a TV via a wireless network Wi-Fi eliminates the need for bulky HDMI cables and provides high data transfer speeds.
In this article, we'll take a detailed look at all available connection methods, from built-in system functions to specialized apps, and also explore solutions for common connection issues.
Technical requirements and preliminary network preparation
Before you begin setting up, you need to make sure that your equipment meets the basic requirements for stable operation of wireless video transmission protocols.
The key condition is the presence of both devices - the smartphone and the TV BQ - in the same local network, that is, they must be connected to the same router.
If you are using a dual-band router that supports both 2.4 GHz and 5 GHz frequencies, it is recommended to connect both devices to the same frequency to avoid network visibility issues.
Make sure your TV's firmware is up to date, as older versions may not correctly support new encryption standards or protocols. Miracast.
It's also worth considering that the speed of your wireless connection directly impacts the quality of the streamed image: viewing video in 4K resolution requires a stable, high-bandwidth channel.
Make sure that the geolocation feature is enabled on your mobile device, as the Android operating system often requires this to detect nearby devices.
⚠️ Important: If your router has a "Guest Network" feature, do not connect devices to it. In Guest Network mode, devices are isolated from each other and will not be able to "see" the TV for signal transmission.
For maximum performance, it is desirable that the distance between the router and the signal receiver does not exceed reasonable limits, and the number of physical obstacles is kept to a minimum.
Some router models have AP Isolation settings that need to be disabled in the admin panel to allow data exchange between devices within your home network.
Connecting Android smartphones via built-in functions
Owners of devices based on the Android operating system have an advantage, since most modern models BQ support native wireless display technology.
To start broadcasting, you don't need to install any additional software; you can simply use the system's standard tools, which may have different names depending on your smartphone manufacturer.
The algorithm of actions usually looks like this:
- 📱 Open the Quick Settings panel on your smartphone by swiping down from the top and find the "Cast," "Smart View," or "Wireless Projection" button.
- 📺 Enable the device search function on your TV BQ, by selecting the item in the signal sources menu
Wireless Displayor similar. - 🔗 Tap your TV's name in the list of available devices on your phone screen and wait for connection confirmation.
Once paired successfully, the image from your phone's screen will be copied completely to the TV, allowing you to display photos, videos from your gallery, or mobile game interfaces.
Some apps, such as Netflix or YouTube, may block protected content from being streamed through the system, requiring the use of the app's built-in features.
⚠️ Please note: When actively using Wi-Fi to stream high-definition video, your smartphone may become very hot. We recommend removing the protective case for better heat dissipation or charging the device.
If you can't find the cast button in the notification shade, check the settings under Connections → Broadcast, where the feature may be hidden or disabled by default.
In models BQ With the Android TV operating system, the search process is automatic, and you only need to confirm the connection on the TV's pop-up window.
Using the BQ Remote app and third-party utilities
For deeper control of your TV and expanded functionality, we recommend using the official app. BQ Remote or its analogues available in stores Google Play And App Store.
These programs allow you not only to stream media files, but also to use your smartphone as a fully-fledged remote control with voice input and keyboard support.
The process of setting up third-party software requires the following steps:
- 📥 Download and install the app BQ Remote or a universal remote control (for example, TV Cast) on your smartphone.
- 🌐 Make sure your phone and TV are connected to the same Wi-Fi network and launch the app.
- 🖥️ In the program interface, click the device search button and select your TV from the list that appears.
Once paired, you can display photos and videos from your phone's memory by simply selecting them in the app interface and pressing the "Cast" or "Play on TV" button.
Universal apps often support more file formats than built-in tools and allow you to adjust volume, brightness, and other image settings directly from your smartphone screen.
Some users prefer to use specialized DLNA servers installed on their phones, which allows them to stream content to any compatible TV, regardless of brand.
This approach is especially convenient if the default application is unstable or does not support the video codecs you need.
Stream content from iPhone and iPad (AirPlay)
Apple technology owners can take advantage of the technology AirPlay, if the TV model BQ supports this protocol or has built-in support for Apple TV.
Otherwise, to organize broadcasting, you will need to install emulator applications on your TV, such as AirScreen or Receiver for AirPlay, available in the Google Play app store on the TV itself.
The instructions for setting up AirPlay are as follows:
- 🍏 Open Control Center on your iPhone (swipe down from the top-right corner or up from the bottom on older models).
- 📺 Click on the "Screen Mirroring" icon and select your TV BQ from the list.
- 🔢 If a code appears on the TV screen, enter it on your smartphone to confirm the connection security.
This technology provides minimal signal lag and high image quality, making it ideal for showing presentations or playing games.
It's worth noting that when using AirPlay through third-party apps on your TV, the load on the Smart system's processor increases, which can lead to micro-jitters in the image during heavy scenes.
⚠️ Note: The AirPlay protocol is sensitive to firewall settings. If the connection fails, check that local traffic is allowed in your Wi-Fi network's security settings.
For stable operation, it is recommended to close background applications on your iPhone before starting a broadcast to free up resources for encoding the video stream.
Also, make sure that all system services responsible for working with Apple protocols are updated on your TV.
Stream media via DLNA and media servers
Technology DLNA remains one of the most reliable ways to transfer large video and music files without the loss of quality and compression typical of screen mirroring.
In this scenario, the phone acts as a server and the TV BQ plays the file directly using its decoders, which reduces the load on the smartphone.
To implement this method, follow these steps:
- 📂 Install a media server application on your phone, for example, BubbleUPnP, LocalCast or a built-in player with DLNA support.
- 🎬 Open the desired video file or music track in the app and tap the "Stream" button (screen icon).
- 📺 Select your TV from the list of renderers and playback will start automatically.
The main advantage of DLNA is that you can turn off your phone's screen or switch to other tasks, and playback on your TV will not be interrupted.
However, this method is not suitable for broadcasting the interface of applications or games, since only a specific media file is transmitted.
Data transfer speed when using DLNA depends on the power of your router and the distance to it, so it is recommended to use a 5 GHz network to view 4K content.
Comparison of connection methods and their characteristics
To make it easier for you to choose the best connection method, we have prepared a comparison table of the main methods available for TVs. BQ.
| Method | Image quality | Signal delay | Phone battery consumption |
|---|---|---|---|
| Miracast (Broadcast) | High (depending on network) | Average | Very tall |
| DLNA | Maximum (without compression) | Absent | Short |
| AirPlay | High | Low | High |
| Applications (YouTube, etc.) | Adaptive | Minimum | Minimum |
As you can see from the table, DLNA is best for watching movies from your phone's memory, while Miracast or AirPlay are best for games and presentations.
Apps like YouTube use their own protocol, which is the most efficient for the smartphone's battery, since the phone only manages the stream, rather than generates it.
Solution and troubleshooting
Despite the ease of setup, users may encounter a number of technical issues, such as audio and video out of sync, connection drops, or the devices failing to see each other altogether.
One of the most common reasons is the use of different Wi-Fi frequencies (2.4 GHz and 5 GHz) with different security settings by clients.
Checklist for diagnosing problems:
- 🔄 Restart your router, TV, and smartphone—this solves 80% of network protocol problems.
- 📡 Check if the "Guest Network" mode is enabled on the router for one of the devices.
- 🛡️ Make sure your antivirus or firewall isn't blocking local connections.
- ⚙️ Reset the network settings on your TV and try connecting again.
If the image is broadcast, but the sound is only coming from the phone, check the audio output settings in the application from which you are broadcasting, or in the Bluetooth/Wi-Fi Direct system settings.
In some cases, changing the phone screen resolution to a more standard one before starting the broadcast helps, for example, 1920×1080.
☑️ Connection diagnostics
⚠️ Note: Operating system and TV interfaces are subject to update. If menu items differ from those described, please refer to the official documentation for your specific model. BQ or update the firmware to the latest version.
