Wireless signal transmission technology Miracast or DLDLNA built into most modern models, making the process simple and accessible.
However, despite the apparent simplicity, owners often encounter various nuances. This may be due to software versions, router settings, or the specifics of the smartphone's operating system. In this article, we'll cover all available methods in detail, from built-in features to third-party apps, so you can enjoy high-quality photos and videos.
Successful synchronization depends on stability Wi-Fi connections and correct network settings. It's important to understand that the TV and phone must be in a unified information space. If you're setting up this interaction for the first time, carefully follow the instructions for your specific operating system.
Technical requirements and equipment preparation
Before you begin setup, you need to make sure your equipment meets the minimum requirements. TVs DEXP must support technology Smart TV and have a built-in wireless module. Older models without support Wi-Fi Direct will require the use of additional adapters such as Google Chromecast or MiraScreen.
The key requirement is that both devices are on the same local network. This means they must be connected to the same router. If your router broadcasts the network on 2.4 GHz and 5 GHz frequencies with different names (SSIDs), ensure that the devices are connected to the same frequency to avoid discovery protocol conflicts.
⚠️ Note: Some providers use "client isolation" mode on public networks or guest profiles. In this mode, devices cannot see each other, even when on the same network. To stream, you must use your home network with isolation disabled.
Check the operating system version on your mobile device. For Android, versions 5.0 and higher are considered current, although for stable operation Miracast It is desirable to have Android 8.0+. Devices iPhone require iOS 12.4 or later to work correctly via the protocol AirPlay, which is supported by new models DEXP.
Using Android's built-in Screen Mirroring feature
Most smartphones are based on Android have a built-in screen mirroring function. On devices Samsung it's called Smart View, on Xiaomi — Broadcast, but on a clean one Android — Screencasting. Televisions DEXP automatically respond to device search requests if the signal reception function is active.

If you are using a phone Huawei or Honor, the function can be called ProjectionThe operating principle remains the same: searching for a device and confirming the connection. It's important to note that when casting the entire screen, the audio is also transmitted to the TV unless otherwise configured in the volume mixer.
⚠️ Please note: During active streaming, your smartphone's battery drains significantly faster. It is recommended to connect your phone to a charger or keep it close to a power bank, especially when watching long videos.
Setting up broadcasting for iPhone owners (AirPlay)

| Delay | Low (up to 0.5 sec) | Ideal for photo/video |
| Sound | Synchronized | Check volume settings |
Some applications such as Netflix or YouTube, may block the output of protected content via system broadcast, requiring the use of the built-in casts button within the application.
Why can't AirPlay find my TV?
If your iPhone can't see DEXP, check that AirPlay is enabled in your TV settings (often found under 'Apple AirPlay and HomeKit'). Also, try rebooting your router, as the Bonjour/Avahi protocol used for discovery can sometimes stall on your local network.
Broadcasting via the YouTube app and other services
The most popular and stable way to watch videos is to use the built-in function Cast in aggregator applications. YouTube, Netflix, IVi Other services also have their own streaming system. Unlike screen mirroring, the phone acts only as a remote control, and the TV downloads the video directly from the internet.
To launch, open the application YouTube On your smartphone, look for the rectangle icon with waves in the upper right corner. Wi-FiClick on it and select your TV. DEXP from the list. The video will start playing on your TV, and controls (pause, volume, rewind) will appear on your phone screen.

Other streaming services work similarly. If you use DEXP with the operating system Android TV, make sure the account Google on the TV and phone is the same or linked via "Family Link" for instant switching of devices without constant searching.
Third-party streaming apps: TV Cast and similar apps
In situations where built-in functions do not work correctly or the TV DEXP is not detected by the system, third-party applications come to the rescue. The market leaders are TV Cast, Web Video Caster And BubbleUPnPThey allow you to stream content from browsers or file managers that is difficult to transmit using standard means.

- 📺 BubbleUPnP — a powerful tool for media library owners, supporting high-bitrate playback of files from DLNA servers and clouds.
- 📲 LocalCast — a simple interface and subtitle support, which is critical for watching films in a foreign language.
Using third-party software can often bypass file format restrictions. If the built-in player DEXP If a specific codec doesn't read, the phone app can transcode the stream on the fly or play it back automatically, transmitting the finished image to the TV.
Solution: Connection and quality issues
Even with proper setup, problems can still occur. The most common problem is the TV. DEXP isn't visible in the device list. First, check if you're using a guest Wi-Fi network. Also, try rebooting your router, as discovery protocols (SSDP) can get stuck.
The second common problem is desynchronization of audio and video, or lag. This is typical for wireless connections, especially if the channel Wi-Fi Your network is overloaded with neighboring networks. Try switching to the 5 GHz frequency if your router and TV support it.

Frequently Asked Questions (FAQ)
Is it possible to broadcast a screen if there is no internet, only a router?
Yes, you can. For the technology to work Miracast or Wi-Fi Direct Internet access is not required. It's enough for the router to create a local network to which both devices are connected. Some TVs allow you to create your own access point for a direct connection to your phone.
Why does the sound come through the phone and not the TV when broadcasting video?
This depends on the app and the casting method. When using Screen Mirroring, the audio usually comes through the TV. If the audio remains on your phone, check your Bluetooth settings (to make sure your phone isn't connected to headphones) or try playing the video through the TV's built-in player using the Cast function.
Do older DEXP TVs support wireless streaming?
Models without Smart TV don't have a built-in Wi-Fi module to receive a signal. They require an external adapter (such as AnyCast or Chromecast), which plugs into the HDMI port and creates a signal receiving point.
How do I stop broadcasting?
On your phone, open the control panel or the app you were using to broadcast and press "Disconnect" or "Stop Casting." On your TV, you can simply switch the signal source (the button Source or Input on the remote control) to a TV channel or another HDMI.
