Modern televisions DEXP These multimedia centers are multifunctional and easily integrated into the home ecosystem. One of the most popular features is the ability to display images from a smartphone directly on a large screen without the need for unnecessary wires. This is especially useful for viewing photo albums, videos, or even playing games with friends. wireless data transmission allows you to enjoy content with high picture quality using only a local network.
However, the setup process doesn't always go smoothly the first time, as there are many nuances depending on the mobile device's operating system and the TV's firmware version. Users often encounter problems with devices simply not recognizing each other in the list of available devices. In this article, we'll detail all the possible ways to get things working. Miracast or DLNA connection so you can stream content as quickly and reliably as possible.
To successfully complete this procedure, you need to understand the basic principles of how a home network works. Your smartphone and TV must be in the same digital environment, meaning they must be connected to the same router. If you're using mobile data on your phone and your TV is connected to your home WiFi, the connection will fail. Local area network is the foundation for any broadcast technology.
⚠️ Important: If your router supports dual-band mode (2.4 GHz and 5 GHz), make sure both devices are connected to the same frequency band. Some older DEXP TV models may not detect smartphones operating in the 5 GHz band if the router hasn't configured the correct band bridge.
Preparing equipment and network
The first step is to check the technical condition of the equipment. Make sure that your TV DEXP equipped with a module Smart TV and has a built-in WiFi adapter. Models without smart features will require an external streaming device, such as a Chromecast or Android TV box. Most modern DEXP series come with the necessary modules built into the housing.
Next, you need to check the operating system version on your smartphone. For Android devices, version 5.0 or higher is recommended, although modern features work better on Android 9+. iPhone users will need iOS 12 or later for stable protocol operation. AirPlayIt's also worth updating your TV's firmware via the settings menu, as manufacturers frequently release patches that improve compatibility with new devices.
☑️ Ready to connect
Signal strength is an important consideration. If the router is located in another room behind thick walls, the video stream transmission speed may be insufficient, resulting in lag or artifacts on the screen. Ideally, the distance between the transmitting device (router) and the receiving devices should be minimal. Channel stability directly affects the smoothness of the picture.
Using the built-in Screen Mirroring feature
The most common method of broadcasting is the use of technology Miracast, which may have different names in different manufacturers' interfaces. On DEXP TVs, this feature is often integrated into the system and doesn't require additional apps. It allows you to fully mirror your smartphone's screen, including system notifications and interface.
To activate the mode on the DEXP TV, you need to press the button Input or Source on the remote control. In the list of signal sources that appears, select Screen Mirroring, Miracast or Wireless DisplayThe TV will go into connection standby mode, and the device name may appear on the screen, which will be visible when searching from a phone.
On an Android smartphone, the search process may vary depending on the manufacturer's operating system. Typically, you need to open the notification shade and find the button. Broadcast, Smart View (Samsung), Projection (Xiaomi) or Screen mirroringOnce the search is activated, the phone will begin scanning the air for compatible receivers. When yours appears on the list DEXP, click on it to pair.
Owners of Apple devices (iPhone, iPad) are even luckier if the TV supports the protocol AirPlay 2Many new DEXP models already have this technology out of the box. You don't need to select a signal source on your TV—just make sure it's turned on. On your iPhone, open Control Center, tap the two rectangles icon, and select your TV. The picture will appear instantly.
⚠️ Please note: When using Screen Mirroring, your smartphone's battery drains significantly faster than usual, as the video processor is working in an enhanced mode. It is recommended to keep your phone charged during extended viewing.
Broadcast via the DEXP Share app
In some cases, standard protocols may not work reliably, and then proprietary or recommended software comes to the rescue. For DEXP TVs, the use of universal intermediary applications is often recommended, such as AnyView Cast or Eshare, which can be found in the official app store on the TV itself (usually the Google Play Store or something similar).
The setup process via the app is as follows: first, you install the appropriate app on your smartphone from Google Play or the App Store. Then, launch the app on your TV via the menu. ApplicationsA QR code or digital key will appear on the TV screen, which you must enter or scan in the mobile version of the program.
The advantage of using specialized apps is their expanded functionality. You can not only mirror your screen, but also display specific files (photos, videos, music) from your phone's memory, controlling playback with the remote or touchpad. The app creates its own data transmission channel, which is often more stable than the system Miracast.
| Method | Latency | Quality | Complexity |
|---|---|---|---|
| Miracast | Low | High | Low |
| AirPlay | Minimum | Very high | Low |
| DLNA (Push-Video) | Absent | Original | Average |
| Applications (Eshare) | Average | Good | Average |
DLNA multimedia streaming
If your goal is not to duplicate the entire screen, but simply to show friends photos from your last vacation or play a movie downloaded in high definition, the technology is best suited DLNAIt doesn't require the smartphone screen to be constantly on and allows playback to be controlled using both the remote control and the phone.
To implement this method, you must have a media player application with DLNA support installed on your smartphone, for example, VLC for Android, MX Player or a standard gallery with the "Stream" feature. Open a video file or photo folder, find the rectangle icon with waves (stream), and select your TV. DEXP from the list.
In this case, the TV acts as a renderer, meaning it decodes the video stream itself, receiving only the data over the network. This means that picture quality is determined by the capabilities of the TV, not the phone. File formats MP4, MKV, AVI Usually they play without problems, but with codecs like HEVC 10-bit Difficulties may arise on older models.
Why does video lag when using DLNA?
If video playback via DLNA is choppy, it's likely your router can't handle the large amount of data it's transmitting. Try lowering the video file's bitrate or moving closer to the router. The issue could also be caused by overheating of the TV's WiFi module.
A unique feature of DLNA is that once playback starts, the phone can be locked or used for other tasks (calls, messaging), and the movie will not be interrupted on the TV. This makes the method ideal for background viewing. However, rewind controls can sometimes experience a delay of a couple of seconds.
Broadcasting from browsers and streaming services
The "Cast" feature within apps deserves special attention. Services like YouTube, Netflix, Okko, and the Google Chrome browser all have a built-in cast button. This is the most convenient way to watch online content, as the TV downloads the video directly from the internet, saving data and battery life.
To use this, open the video in the app on your phone and tap on the icon Cast (rectangle with WiFi corner). Choose your DEXPIt's important that your app accounts (if authorization is required) are active. The Chrome browser allows you to send an entire tab to your TV, which is convenient for viewing video sites that don't have a separate app.
It's worth noting that some streaming platforms may block streaming to "non-certified" devices or require the use of proprietary TV apps. With DEXP, which is often based on Android TV or similar systems, this usually doesn't pose any issues, but DRM-protected content (such as 4K on Netflix) may only work through the native TV app.
⚠️ Note: App and website interfaces are constantly being updated. The location of the Cast button may change. If you don't see the Cast icon, check if it's hidden in the "More" menu (three dots) or in the player settings.
Troubleshooting connection issues and errors
Despite the simplicity of the technology, users often encounter errors. The most common one is "Device not found." This almost always means that the phone and TV are on different subnets. Check if the "Guest Network" feature is enabled on the router for one of the devices, as it isolates the devices from each other.
Another common issue is audio and video desynchronization or constant buffering. This indicates an overloaded WiFi channel. Try disconnecting other bandwidth-consuming devices (torrents, downloads) or switching your TV to a wired connection. LAN, if the DEXP model has such a port. A wired connection is always more stable for receiving heavy video streams.
If all else fails, reset the network settings on both devices. On the TV, you can do this through the menu. Settings → System → Reset (Be careful, this will delete installed apps.) On your phone, simply select "Forget network" for your WiFi and reconnect. This often clears the connection error cache.
Additional features and settings
Once successfully connected, new options open up. You can use your smartphone as a remote control by installing the app. Android TV Remote Control or something similar. This allows you to conveniently type text for searching on YouTube, which is time-consuming and inconvenient with a regular remote.
Many modern DEXP TVs also support Game Mode, which reduces input lag when streaming. If you plan to play mobile games on the big screen, be sure to enable Game Mode in your TV's picture settings for more responsive controls.
Is it possible to stream a screen without a WiFi router?
Yes, some TV and smartphone models support WiFi Direct or Miracast without an access point. In this case, the phone connects directly to the TV's WiFi module. However, the speed and stability of this connection are usually lower than with a full-fledged router.
Why is there no sound during the broadcast?
Check the audio settings in the app you're casting from. Sometimes the sound stays on your phone, but the picture stays on your TV. Also, make sure your TV isn't set to "Video Only" or a similar setting in the Miracast connection settings.
Does DEXP support 4K streaming?
Most modern DEXP models with a screen size of 43 inches or larger support 4K. However, wireless streaming of 4K content requires a very powerful router (AC or AX standard) and close proximity to the devices. Otherwise, the quality will automatically drop to 1080p.
