Modern smartphone users often face the need to display images from their mobile device on a larger screen. Owners of this brand's technology Honor are no exception, especially given the popularity of these gadgets in combination with affordable TVs DEXPWireless connection via a local Wi-Fi network is the most convenient way to avoid unnecessary wires and distance limitations.
The setup process may vary depending on your operating system version. Android and TV models, but the basic principles remain the same. The key condition Successful synchronization requires both devices to be on the same subnet. This means the smartphone and TV must be connected to the same router, regardless of whether the TV uses a wired connection or both devices use a wireless connection.
In this article, we'll take a detailed look at all available methods, from built-in system functions to specialized applications. You'll learn how to set up Miracast, use the protocol DLNA for multimedia and what to do if standard tools don't work. Understanding the technical nuances will help you avoid common mistakes and ensure stable high-definition signal transmission.
Basic requirements and equipment preparation
Before proceeding with the actual setup, you need to make sure that the equipment is ready. Connection stability Depends directly on the quality of the wireless network signal. If the router is too far from the receiver or smartphone, you may experience image lag or connection interruptions.
Make sure your router supports the standards 802.11n or newer (ac, ax). Use of outdated standard equipment 802.11g This may prevent high-definition video from being transmitted. It's also important to ensure that client isolation is not enabled on your router, if such a feature is present in your security settings.
⚠️ Note: Some dual-band routers may separate the 2.4 GHz and 5 GHz networks into different names (SSIDs). For proper streaming, ensure that your DEXP TV and Honor phone are connected to the same network, and not to different frequency bands with different names.
Check that the software on both devices is up to date. Manufacturers regularly release updates that fix bugs in the modules. Wi-Fi Direct and data transfer protocols. On DEXP TVs, updates often occur automatically, but manually checking in the menu is a good idea.
Using the built-in Wireless Projector function
Smartphones Honor, running EMUI or Magic UI, are equipped with a built-in screen mirroring feature. This technology is based on the standard Miracast, which allows you to transmit video and audio without the delays that are typical for some other methods.
To activate the feature, pull down the notification shade and find the "Wireless Projector" or "Projection" icon. If the icon is not in quick access, go to Settings → Other connections → ProjectionOnce turned on, the phone will begin searching for available devices within the network range.
On your DEXP TV, you also need to activate the corresponding mode. Depending on the model and firmware version, this mode may have a different name. Use the remote control to navigate to the signal source menu and select the option. Multimedia → Wireless Display or Wi-Fi Display.
- 📱 Make sure your phone screen is unlocked before you start searching for devices.
- 📺 On the DEXP TV, the signal reception mode must be activated before starting the search on the smartphone.
- 🔄 If the device is not found, try restarting the Wi-Fi module on both devices.
Once paired successfully, the image from your smartphone will appear on the TV screen. It's important to understand that in this mode, all screen content is displayed, including notifications and system messages. Permission The images will automatically adjust to the TV matrix, which may lead to a change in the proportions on the phone itself.
Setting up DLNA for streaming media files
If your goal is not to duplicate the interface, but to view photos or videos stored in the phone's memory, the optimal solution would be the protocol DLNAIt allows the DEXP TV to act as a renderer, playing content stored on the smartphone.
Most modern DEXP models support this technology out of the box. To start playback, simply open the gallery or video player on your Honor, select the desired file, and tap the streaming icon (usually a rectangle with waves in the corner). Your TV should appear in the list of available devices.
However, standard Android tools don't always work correctly with all video file formats. In such cases, it's recommended to use specialized player apps, such as VLC for Android or BubbleUPnPThey have their own codecs and more flexible connection settings.
Why might video lag when using DLNA?
When transferring large files (4K, high bitrate) via Wi-Fi, buffering may occur. This is due to limited wireless bandwidth or the TV's processor load. Solution: Reduce the quality of the streamed video or use a wired Ethernet connection to the TV.
The advantage of DLNA is the ability to control playback from your phone. You can pause, rewind, and adjust the volume without leaving your couch. This also saves battery life compared to full screen mirroring via Miracast.
Using third-party synchronization applications
In situations where built-in tools don't work or their functionality isn't sufficient, third-party solutions come to the rescue. For DEXP TVs, especially models with the operating system Android TV, there are many receiver applications.
One of the popular solutions is to install an application AirScreen or Receiver for Chromecast Directly to your TV (via the Google Play store on your TV). After installing and launching this app, the TV emulates a standard receiver recognized by your Honor phone.
Honor phones also have utilities that expand connectivity options. For example, the app TV Cast for DEXP Universal custom launchers can offer alternative search and connection algorithms. It's important to choose apps with high ratings and recent update dates.
| Application | Connection type | 4K support | Do you need a router? |
|---|---|---|---|
| Wireless projector | Miracast | Depends on the model | Yes (local network) |
| Google Home | Chromecast built-in | Yes | Yes |
| AirScreen (on TV) | AirPlay/Miracast | Yes | Yes |
| VLC Player | DLNA/Cast | Yes | Yes |
Using third-party software gives you more control over the process. You can adjust the bitrate, select a codec, and manage the playback queue. However, keep in mind that free versions often contain ads that can interrupt your viewing experience.
Troubleshooting device discovery issues
The most common issue is that the Honor phone simply doesn't see the DEXP TV in the list of available devices. This can be caused by router firewall settings or issues with the Wi-Fi module drivers.
First, try rebooting your router. Often, a temporary IP address (DHCP) issue prevents devices from being correctly identified on the local network. It's also a good idea to forget the Wi-Fi network on your phone and reconnect using the password.
☑️ Connection diagnostics
In some cases, manually entering the IP address helps. If the streaming app allows you to add a device by IP, find the TV's address in your router's network settings and enter it manually. This eliminates automatic search errors.
⚠️ Warning: Antivirus apps on your smartphone or the "Network Protection" feature in some Android operating systems may block local connections. Try temporarily disabling them to test this hypothesis.
Features of working with different versions of Android
The interface and menu item names may vary depending on the version. Android and shells Magic UIOn new Honor models lacking Google services, the process may differ from devices with the full range of services.
On devices without Google Play Services, some casting features may not work reliably. In this case, it is recommended to use the web versions of services or install apps through alternative stores, such as AppGallery or Petal Search.
It's also worth keeping in mind that older versions of Android (below 7.0) may not support the modern video compression codecs used by recent DEXP TVs. In such cases, screen mirroring is only possible in low resolution.
Comparison of wired and wireless methods
Although this article focuses on Wi-Fi, it's important to mention alternatives. Wireless connections are convenient, but they're always inferior to wired connections in terms of stability and speed. For gaming or viewing 4K content with high bitrates, a cabled connection is a better option.
Using an adapter USB-C to HDMI This allows for perfect picture quality without lag. However, it reduces mobility and requires a free HDMI port, which is often occupied by an antenna cable or set-top box.
For office presentations or sharing photo albums, Wi-Fi is ideal. The portability and freedom from tangled wires outweigh any potential delays. The choice of method depends solely on your current needs.
Why doesn't my DEXP TV connect to my phone's Wi-Fi network?
DEXP TVs typically cannot receive a signal directly from a phone's access point (tethering) for screen sharing using the classic Miracast method. They require a shared router to coordinate data exchange between devices. A direct connection is only possible using Wi-Fi Direct, if specifically supported by the TV model.
Is it possible to connect Honor to DEXP without a router?
Yes, if both devices support Wi-Fi Direct technology. In this case, they create a direct connection with each other. However, this connection is less stable, and functionality is often limited to screen mirroring on the TV without internet access.
Does internet speed affect image quality during broadcasting?
When using Miracast (screen mirroring), you don't need an internet connection at all; traffic flows within the local network. When using DLNA or online services (YouTube, Netflix), internet speed is critical for content buffering, but the local Wi-Fi speed of the router is more important for data transfer between the phone and TV.
How to improve sound quality when connected via Wi-Fi?
If the audio lags behind the video or is of poor quality, try changing the sound mode to "Standard" in your DEXP TV settings or disabling additional effects. Also, make sure that third-party equalizers aren't enabled on your phone that interfere with streaming.
What to do if the image is stretched to fill the entire screen?
Use your DEXP TV remote to locate the aspect ratio button (often labeled "Format," "Aspect," or a rectangle icon). Select "Original," "16:9," or "Just Scan" to remove cropping from the edges of the image.
