Modern TVs of the brand Dexp They are often based on the Android operating system, which opens up a wide range of multimedia options. One of the most popular features is the ability to wirelessly display images from a smartphone on a large screen. Wi-Fi Direct Allows you to create a direct wireless connection between devices, bypassing your home network and router. This ensures high data transfer rates and stable images when watching videos or presentations.
Unlike classic DLNA, which requires a shared router, the Direct protocol works directly. Users don't need to worry about setting up complex network equipment or having an active internet connection. Simply configure both devices correctly, and they will see each other in the list of available devices. The Wi-Fi Direct protocol supports video transmission in resolutions up to 4K, if the TV and smartphone hardware allows it. In this article, we'll cover all connection steps in detail, including possible interface nuances and solutions to common problems.
It's worth noting that the menu interface may differ depending on the model year and firmware version installed. Manufacturers regularly update their software, changing the layout of some menu items. If you don't find an exact match, look for sections with similar meanings related to network connections or the display.
Equipment preparation and preliminary checks
Before you begin setup, you need to make sure your equipment is ready for use. Most modern models Dexp Some TVs have a built-in wireless module, but budget or older models may not have it. Check your TV's specifications in the documentation or on the manufacturer's official website. Make sure the remote control is working properly and the batteries are charged, as menu navigation will be active.
The operating system version on your smartphone also plays an important role. For stable operation of the technology Miracast (which is often used over Wi-Fi Direct) requires Android devices running OS version 4.2 or higher. iPhone owners should be aware that native support for this protocol is limited and may require third-party apps.
Make sure Wi-Fi is enabled on both devices. Even if you don't plan to access the internet, the radio should be activated to scan for nearby devices. Disable Airplane Mode on your phone and ensure the TV isn't in deep sleep or power saving mode, which could disable network adapters.
☑️ Check before connection
It's important to understand that when connected via Direct, your phone's internet traffic may not be consumed, as data is transferred locally. However, some apps may require network access to authorize content before streaming. Check the Google Play Store for updates to the "Cast" or "Screen Mirroring" system apps in advance.
Activating the feature on a Dexp TV
Enabling signal reception on your TV is the first step. Turn on your TV and wait for the operating system to fully load. Take the remote and press the menu button, often marked with a gear symbol or the words SettingsIn the window that opens, you need to find the section responsible for network connections.
Depending on the shell version Android TV or branded shell DexpThe path may look different. Typically, it's the "Network & Internet" or "Connections" tab. Within this section, look for "Wi-Fi Direct." On some models, this feature may be located in a separate app on the home screen, called— Wi-Fi Direct or Screen Mirroring.
⚠️ Attention: On some TV models, the function may be hidden in the "Additional" menu or require switching the signal source (buttonSourceorInput) to the appropriate input, for example, “Wireless Display”.
Once the feature is activated, the device's name will appear on the TV screen and will be visible to other devices. This is often the model name of the TV and its set-top box, for example, Dexp-40D7000The screen may also display the status "Waiting to connect" or "Ready to connect." Do not close this window until pairing is successful.
What should I do if the Wi-Fi Direct option is not in the menu?
If you don't see this option, your TV model may not support the technology directly or it may be built into another app. Try looking for the "Anyview Cast," "Eshare," or "Miracast" app in the list of installed apps on your TV. Manufacturers often use third-party solutions to implement this feature. Also, check the "About TV" -> "System Update" section, as the menu may have changed in new firmware updates.
If the TV prompts you to select a connection method, such as "PIN Code" or "Auto," select Automatic to simplify the process. If manual entry is required, remember or write down the displayed code; you'll need it to confirm the connection's security.
Setting up a connection on a smartphone
Now let's move on to setting up your mobile device. The interface may vary depending on your smartphone brand (Samsung, Xiaomi, Honor, etc.), but the steps are the same. Open the system settings and go to "Connections" or "Wireless Networks." You're looking for the option responsible for image output.
This feature has different names on different devices. Look for the following names in the list:
- 📱 Smart View (for Samsung devices)
- 📺 Broadcast (standard Android)
- 📡 Connecting to a wireless display
- 🖥️ Projector or Wireless projector (Xiaomi/Redmi)
After clicking the corresponding item, the phone will begin scanning for available devices within range. Make sure you're close to the TV, within 5-7 meters, and there aren't any thick concrete walls between them that could interfere with the signal. When your name appears on the list, Dexp TV, click on it.
If the system requests permission to connect, a confirmation pop-up may appear on the TV screen. Use the remote control to select "Allow" or "Accept." Your smartphone's screen should then be mirrored on the TV. Picture quality may be a bit rough for the first few seconds until a stable connection is established.
Compatibility and characteristics table
Understanding technical limitations will help avoid disappointment. Not all devices operate the same, and latency may vary. Below is a table showing the relationship between connection quality and the standard and hardware version used.
| Parameter | Wi-Fi Direct (Miracast) | DLNA (via router) | HDMI cable |
|---|---|---|---|
| Presence of a router | Not required | Necessarily | Not required |
| Latency | Low/Medium | High | Absent |
| Video quality | Up to 1080p/4K (compressed) | Up to 4K (uncompressed) | Up to 8K (uncompressed) |
| Battery usage | High | Average | Charging your phone |
As can be seen from the table, Wi-Fi Direct It's a happy medium between convenience and quality. It's wireless, yet provides low enough latency for viewing videos and photos. However, for high-motion gaming, a wired connection is better, as even minimal latency in wireless mode can be noticeable.
It's worth keeping in mind that when connecting via Direct, your phone may lose internet access if it doesn't support both Wi-Fi for internet and Wi-Fi Direct. Modern smartphones with dual-band modules (2.4 GHz and 5 GHz) solve this problem: one band is dedicated to Direct, while the other remains for internet access.
Using third-party apps for broadcasting
If you can't use the built-in system tools, or the functionality seems limited, third-party applications can help. Store Google Play and the TV app store offer a variety of solutions. One popular option is the app TV Cast or Dexp Share (if available for your model).
To install the app on your TV, you will need to go to the Apps section on the home screen. DexpFind the search bar and enter the program name, such as "AirScreen" or "Receiver for Miracast." Download and install the selected software. After launching, follow the on-screen instructions to activate the receiving mode.
⚠️ Attention: When installing third-party apps, pay attention to the permissions they request. Some programs may require access to your microphone or contacts, which aren't necessary for screen sharing. Choose trusted, highly rated apps.
You may also need to install a companion app on your smartphone. Often, after installing the app on your TV, a QR code or download link for the mobile client appears on the screen. Scanning the code will take you to the download page for the appropriate version for your OS. This ensures maximum compatibility and stability.
Third-party solutions often offer support for additional codecs and file formats that aren't supported by the TV's default player. You can stream MKV or AVI videos directly from your file manager by selecting the "Stream to Device" option.
Solutions to common problems and errors
Despite the simplicity of the technology, users may encounter difficulties. One common issue is the TV not detecting the phone, or vice versa. First, check whether the connection is blocked by your antivirus or firewall, if one is installed. Also, ensure that the date and time are set correctly on both devices; clock synchronization issues can prevent a secure connection.
If the image is streaming but is choppy or intermittent, this indicates interference or a weak signal. Try moving closer to the TV. Wi-Fi congestion could also be the cause, especially if there are many other networks nearby. You can try changing the channel in your router settings (if it's affecting your router) or in Wi-Fi Direct settings, although this is done automatically in Direct mode.
Another common error is a "black screen" when playing videos from protected sources (Netflix, Kinopoisk, etc.). This is not a malfunction, but rather content copy protection. HDCPWireless streaming of protected video is often blocked by copyright holders. In such cases, the only solution is a cable connection or using the "Cast" feature within the app itself, if it supports Chromecast built-in.
The procedure for resetting network settings:1. Go to Settings -> Network.
2. Select "Reset network settings" or "Remove all networks".
3. Restart the TV (unplug it completely from the power outlet for 1 minute).
4. Repeat the pairing procedure again.
