This is especially convenient for sharing photos with friends, watching a movie from an online cinema on your smartphone, or presenting a presentation. Wireless connection eliminates the need to search for adapters, HDMI cables and run wires across the entire room, ensuring a clean and tidy interior.
However, syncing gadgets doesn't always go smoothly the first time. Users often encounter problems with the TV not detecting the phone, or with a delay in the image. In this article, we'll take a closer look. connection algorithms For Android and iOS, we'll explore the built-in features of the DEXP system and third-party apps. You'll learn how to set up local network and eliminate common communication errors.
To get started, make sure your DEXP TV supports the function Smart TV and has internet access. If the model is older and doesn't have built-in Wi-Fi, you'll need an external adapter or a TV set-top box. Below, we'll cover all the current streaming methods available.
Preparing equipment and a Wi-Fi network
The foundation of stable wireless data transmission is proper organization local networkThe most important rule, the violation of which leads to 90% of connection problems: both devices—the smartphone and the DEXP TV—must be on the same subnet. This means they must be connected to to the same router.
A common mistake is using the "Mobile Hotspot" feature on your phone to share internet with your TV. While this will technically create a network, many broadcast protocols (especially DLNA) may be blocked due to mobile OS security settings or carrier restrictions. It's best to use your home Wi-Fi router.
⚠️ Note: If your router supports two frequency bands (2.4 GHz and 5 GHz) and they have different network names (SSIDs), make sure your phone and TV are connected to the network with the same nameIn some cases, routers isolate devices in different bands, preventing them from detecting each other.
It is also worth checking that the latest software is installed on your DEXP TV. system updatesManufacturers regularly release patches to improve the performance of wireless modules. Go to the settings menu and find the firmware update section.
Check the Wi-Fi signal where the TV is installed. If the signal is weak, the video stream may be choppy or have low resolution. 4K broadcasts content requires high bandwidth.
Using the built-in Screen Mirroring (Miracast) feature
The most universal method that does not require installation of additional software is the technology Miracast (often referred to as Screen Mirroring, Wireless Monitor, or Casting). On DEXP TVs, this feature is typically built into the Android TV or Yandex.TV interface.
To start the process, find the button with the name on the DEXP TV remote control Input or Source and select the signal source Screen Mirroring, Miracast or Wireless transmissionA waiting connection image with the name of your TV will appear on the screen.
☑️ Check before connecting Miracast
Now let's move on to the smartphone settings. Depending on the model and version operating system, the path to the function may differ:
- 📱 Samsung: Pull down the notification shade and tap Smart View.
- 📱 Xiaomi/Redmi: Find the button in the notification shade Broadcast (or in Settings → Connection and sharing → Broadcast).
- 📱 Honor/Huawei: the function is called Screen projection.
- 📱 iPhone: use Screen mirroring (requires AirPlay support on TV).
Once the feature is activated, the phone will begin searching for available devices. When yours appears in the list DEXP TV, click on it. A permission request may appear on the TV screen—confirm it with the remote.
⚠️ Attention: When using Miracast, your phone's screen is mirrored entirely on your TV. This means incoming calls and notifications will be visible to everyone. Furthermore, your smartphone's screen will drain battery power.
Broadcasting via the YouTube app and other services
If your goal is to watch videos from online services such as YouTube, Netflix, or online cinemas (Ivi, Okko, Kinopoisk), using full screen mirroring (Miracast) is ineffective. It puts unnecessary strain on the phone's processor and router. It's much better to use the built-in protocol. Google Cast (Chromecast built-in).
The operating principle here is different: the phone acts as a remote control, transmitting only a link to the video stream to the TV. video stream The DEXP TV downloads content directly from the internet via its Wi-Fi module. This ensures maximum picture quality and zero lag.
The algorithm of actions is extremely simple:
- Open the YouTube app on your smartphone and on your DEXP TV (it must be running).
- Click on the icon in the app on your phone Broadcast (rectangle with waves in the corner).
- Select your TV from the list DEXP.
Once paired, the video will play on the big screen, and you can use your phone to control the volume, rewind, or even access other apps without interrupting the viewing experience. This method is ideal for energy savings mobile device.
| Parameter | Miracast (Screen Casting) | Google Cast (YouTube, etc.) |
|---|---|---|
| Video source | Smartphone (uses up traffic and battery) | Internet (via TV) |
| Impact on the phone | The screen is active, you cannot use other apps | You can turn off the screen and use other apps. |
| Quality | Depends on the Wi-Fi signal between the phone and the router | Maximum (4K HDR), stable |
Connecting an iPhone (iOS) to a DEXP TV
Apple device owners need to know that the iOS ecosystem uses its own protocol AirPlay 2Modern DEXP TVs running Android TV often have built-in AirPlay support, allowing you to connect your iPhone without any hassle.
You can check for support by opening Control center on iPhone (swipe down from the top right corner on newer models or up from the bottom on older models). Tap the button Screen mirroring (two rectangles). If your DEXP TV is listed, you're in luck; the connection will be instant.
What to do if AirPlay isn't working?
In some regions or on older DEXP firmware versions, AirPlay support may be disabled by default. Try going to your TV's settings, under 'Apps' or 'System', and finding 'AirPlay'. Make sure it's enabled. A firmware update may also be required.
If there is no built-in support, the situation can be resolved by installing a special app on the TV itself. Go to Google Play Store on your DEXP TV and find the "AirScreen" or "AirPin" app.
Once installed and launched on your TV, this app emulates an AirPlay receiver. Your iPhone will see your TV as a standard Apple TV device. This allows you to stream photos, videos from your gallery, and even gameplay with minimal latency.
Third-party streaming apps (DLNA and others)
Sometimes built-in tools are not functional enough or work unstable. In such cases, third-party applications, which use the DLNA protocol. They allow you to stream media files (videos, photos, music) from your phone to your TV without screen mirroring.
One of the most popular solutions is the application TV Cast for DEXP or universal combines like Web Video Caster. The principle of their operation:
- 📺 Install the application on your phone.
- 📺 Make sure that your TV and phone are on the same network.
- 📺 Run a scan in the app, it finds DEXP TV.
Such programs are especially useful for playing video formats that are not supported out of the box by the TV's built-in player, or for streaming video from browsers that do not have a Cast button. converts stream on the fly into a format understandable for TV.
⚠️ Attention: Free versions of streaming apps often contain ads that may pop up at inconvenient times. Additionally, some may have session length or image quality limitations (for example, 720p).
For advanced users who want to organize a full-fledged media center, it is recommended to install the application on the TV VLC for Android or KodiThey have built-in support for network resources and can see shared folders on a smartphone (if the corresponding file manager is available on Android).
Troubleshooting: TV doesn't detect phone
Despite the simplicity of the technology, users often encounter situations where devices don't work together. If DEXP doesn't appear in the list of available devices on your phone, follow these steps: diagnostics.
The first and most common thing to do is reboot. Unplug the TV (not put it in standby mode, but completely disconnect it for 10 seconds) and reboot your smartphone. This will clear the network service cache and reset frozen apps. network processes.
The second important point is the antivirus or firewall settings on the router. Some providers or router settings include a function AP Isolation (Access Point Isolation). Designed for security in public places, this feature prevents devices within the same Wi-Fi network from communicating with each other.
It's also worth checking the date and time on both devices. Time desynchronization can cause errors. security protocols SSL/TLS, which is why the handshake between devices does not occur.
In rare cases, resetting the network settings on your DEXP TV can help. To do this, go to Settings → System → Reset (Be careful, this may delete installed apps.) A more gentle option is to forget the Wi-Fi network in the TV settings and reconnect it using the password.
Why does the video stream stutter or lag when streaming?
Audio lag or image stuttering (artifacts) are most often caused by Wi-Fi congestion. If the router is located far away or the signal passes through thick walls, the bandwidth is insufficient for a high-bitrate stream. Solution: Move the router closer, switch to the 5 GHz band, or reduce the video quality in the player settings.
Is it possible to connect a phone to DEXP without Wi-Fi?
Yes, but only with a cable. You'll need a USB-C (or Lightning) to HDMI adapter. The DEXP TV switches to HDMI mode, physically duplicating the image. This is the best option for gaming, as it eliminates input lag.
How to improve picture quality over a wireless connection?
In the streaming settings on your phone (if available), select the maximum resolution. Make sure your TV's picture mode is set to "Movie" or "Standard," not "Vivid," which often distorts colors. Also, disable QoS on your router if it's not prioritizing traffic correctly.
Does DEXP support audio transmission to external speakers during broadcasting?
When using Miracast, audio typically goes through the TV. If a Bluetooth headset or soundbar is connected to the TV, the audio may also go there. However, when using the Cast protocol (YouTube), audio output control can be more flexible and allow you to select the audio output device separately.
Is it safe to connect my personal phone to public Wi-Fi for streaming?
No, it's best not to use streaming features in public places (cafes, hotels), as other network users could potentially access your device or intercept your data stream. Use only trusted home networks.
