Wireless technology Provides sufficient speed for high-definition image transmission, allowing you to enjoy content in HD or even 4K quality, depending on your TV model. In this article, we'll cover all the current connection methods and their potential nuances in detail.
It's worth noting that connection quality directly depends on the stability of your home network and the distance between the router and the signal receiver. DEXP They use standard operating systems such as Android TV or proprietary Linux-based shells, making them compatible with most smartphones. It's important to configure your network settings correctly to avoid playback lag.
Network and equipment preparation requirements
Before setting up the stream, you need to make sure your equipment is ready. A fundamental requirement for a successful connection is that both devices are on the same local network. This means that both the smartphone and TV must be connected to the same router, either via WiFi or an Ethernet cable for the TV.
Please pay attention to your router's frequency range. For transmitting heavy video streams without buffering, it's preferable to use a network. 5 GHz, which provides higher throughput. If your router is dual-band, make sure both devices are connected to the 5 GHz frequency. A 2.4 GHz connection is also possible, but at a slower speed.
⚠️ Note: If your router uses AP Isolation mode, devices will not be able to "see" each other. This mode is often enabled on guest networks or public access points, blocking local communication.
It's also worth checking the TV's software version. Manufacturers periodically release updates that improve the stability of the WiFi module and add support for new codecs. You can update the firmware through the settings menu by selecting Settings → About TV → System Update.

Using the built-in Screen Mirroring (Miracast) feature
The most universal method is to use Miracast technology, which is built into most modern Android smartphones and DEXP Smart TVs. This technology allows you to mirror your mobile device's screen to your TV in real time, transmitting everything that's happening on your phone's display.
To start the process, find the button with the name on your TV remote control. Input, Source or the dedicated button with the screen icon with an arrow. In the signal source menu that opens, select "Miracast," "Wireless Display," or "Cast." A connection message will appear on the screen.
On an Android smartphone, the process may vary depending on the model. Typically, you need to open the notification shade and find the button. Broadcast, Smart View, Wireless projector or CastOnce the search is activated, your phone will find your DEXP TV in the list of available devices.
Click the TV's name, and within a few seconds the image should appear on the big screen. If the system prompts you to confirm, use the remote to confirm. Picture quality depends on the WiFi channel's congestion, so short delays are possible in cases of heavy interference.
☑️ Pre-broadcast check
Broadcasting via the YouTube app and other services
If you want to watch videos from popular platforms like YouTube, Netflix, or online movie theaters, using the built-in features of these apps is the best solution. This method doesn't mirror the entire screen, but rather starts playback directly on the TV, using your phone only as a remote control.
Open the YouTube app on your smartphone and find the video you want to watch. Tap the icon in the upper right corner or at the bottom of the player. Broadcast (rectangle with WiFi waves). Select your DEXP TV from the list of devices.
An important advantage of this method is that the phone does not consume battery power to encode the video stream and transmit it over the air. TV Automatically downloads videos from the internet, ensuring more stable quality and high resolution, up to 4K, without jerking or artifacts.
What should I do if the broadcast button doesn't appear?
Make sure the apps on your phone and TV are up to date. Also, check that both devices are on the same subnet. Sometimes, rebooting the router or reconnecting to the WiFi network on both devices helps. In rare cases, resetting the network settings on the TV via the menu may be necessary.
Many other services work similarly. For example, in online cinema apps (ivi, Okko, Kinopoisk), the streaming icon also allows you to switch to a larger screen. This eliminates the need to keep your phone on the entire time you're watching.
View photos and videos via DLNA
DLNA technology is ideal for viewing your smartphone's media library (photos, personal videos, music). It allows your TV to access files on your phone over the network without requiring full screen mirroring.
Many modern file managers and photo galleries on Android have built-in DLNA support. You can also use specialized apps like BubbleUPnP or LocalCast. After installing the app and running a network scan, it will find your DEXP TV.
Select the files you want to play and tap the on-screen display icon. The TV will open the built-in player and begin playback. This method is great because it allows you to create playlists and manage your playback queue directly from your smartphone.
| Method | Quality | Delay | Battery consumption |
|---|---|---|---|
| Miracast | High | Low | High |
| YouTube Cast | Maximum | Absent | Short |
| DLNA | Original | No | Average |

Troubleshooting connection issues
Despite the simplicity of setup, users may encounter difficulties. One of the most common issues is that the TV doesn't see the phone in the list of available devices. In this case, the first step is to check whether Band Steering is enabled on the router, which can sometimes hide devices from each other.
Try temporarily disabling mobile data (3G/4G/5G) on your smartphone. Some devices prioritize mobile data even when Wi-Fi is enabled, which can cause conflicts when searching for local devices. Restarting both devices one at a time also helps: first turn off the TV, then the phone, and then turn them back on.
⚠️ Warning: Antivirus programs or firewalls on your smartphone may block local connections. If all else fails, try temporarily disabling network protection in your phone's security settings.
If the image is streaming but the sound is missing or out of sync, the problem may be with the codecs. Try changing the quality settings in the source app or updating the TV's firmware. Sometimes resetting the network settings on the TV via the menu helps. Settings → Network → Reset network settings.
Alternative methods and third-party applications
If standard methods don't work or your DEXP TV's functionality is limited, third-party apps can help. For Android TV, there are apps that expand connectivity options, such as AirScreen or Receiver for AirPlay if you're using an iPhone.
iPhone owners may encounter a problem with DEXP not supporting AirPlay natively. In this case, installing an AirPlay emulator app on your TV (if the TV app store allows it) will solve the problem. After installing the app on your TV, your iPhone will see it as a native Apple TV device.
For advanced users, there's the option of using the Chromecast built-in protocol. If your DEXP specifications indicate Chromecast support, you can cast a Chrome browser tab directly to your TV. To do this, select Broadcast and select the device.
In conclusion, it's worth noting that connecting your phone to a DEXP TV via WiFi is a flexible process that depends on many factors. Proper router configuration and choosing the appropriate streaming method will ensure you enjoy comfortable viewing on a large screen without the hassle of unnecessary wires.
Why doesn't the DEXP TV see my phone?
Most often, the problem is that the devices are connected to different networks (for example, one to a guest network and the other to the main network) or client isolation is enabled on the router. Also, check if the network's SSID is hidden.
Is it possible to connect an iPhone to DEXP wirelessly?
Yes, if your TV supports AirPlay 2 or Miracast (via third-party apps). Otherwise, you'll need Lightning/MHL to HDMI adapters or cables.
Does phone connection affect internet speed?
When using Miracast, the phone actively transmits data, which can consume a significant portion of the WiFi network. When using Cast mode (YouTube), the load on the phone is minimal, as the TV downloads the video automatically.
How to improve picture quality during broadcasting?
Move closer to the router, close unnecessary apps on your phone that are freeing up RAM, and switch the router to 5 GHz only mode, if possible.
