Modern users rarely use only built-in Smart TV applications; there is often a need to broadcast images from a smartphone or tablet to a large screen. Technology Wi-Fi Direct Allows you to create a direct connection between devices without a router, significantly simplifying the data exchange process. DEXP device owners often have difficulty finding this option, as its location depends on the operating system version.
In this article, we'll detail the steps for various platforms installed on DEXP TVs. You'll learn the difference between the standard protocol and Miracast and how to properly configure screen mirroring if automatic search fails. DEXP uses different firmware, so there is no universal button, but there are general principles for navigating the menu.
Understanding how wireless interfaces work will help you avoid connection errors and enjoy high-quality content. We'll cover the nuances of working with Android TV, Linux systems, and specific operating systems often found on budget models.
Differences between Wi-Fi Direct and Miracast on DEXP TVs
Many users confuse these two concepts, although technically they solve similar problems using different methods. Wi-Fi Direct — is a standard that allows devices to connect directly, creating their own network, while Miracast — is a multimedia transmission protocol that often uses Wi-Fi Direct to establish a communication channel. In the DEXP TV interface, these functions may be combined or separated depending on the model.
On Android TV devices, the search is done through the casting menu, not the classic network menu. On simpler Linux-based or proprietary models, the function is found in the network settings or dedicated apps. It's important to understand that for this to work, Miracast a router is really not needed, the connection is established (point-to-point).
If your TV supports the standard DLNAThis is another method for transferring media files, but it requires a router and is different from a direct connection. For gaming consoles or mirroring your phone's desktop, a direct connection or Miracast is preferable, as they provide lower signal latency.
Finding the feature on DEXP Android TVs
The most common situation is using a DEXP TV with an operating system installed Android TV or Google TVIn these systems, the classic "Wi-Fi Direct" menu is often hidden or renamed, as Android uses built-in broadcasting mechanisms. You don't need to search for a separate switch in the network settings; simply enable the signal reception function.
To start broadcasting, you need to go to the system settings. Find the section Settings, then select the item Preferences or SystemThis is where the key parameters for the device's visibility to external devices are hidden. In some firmware versions, the path may look like this: Settings → Device → Settings.
Inside the menu you need to find the option Broadcast (Cast) or Google CastMake sure the slider is enabled. It's also worth checking the device name settings so you can easily find your TV in the list of available networks on your smartphone. The default name usually includes the TV model, for example, DEXP-U50.
☑️ Android TV setup
If the standard search does not help, you can use the built-in application Chromecast built-inIn this case, the phone and TV must be on the same network, or you can use guest mode to connect. Keep in mind that some Google service setup may still require a short internet connection for some features to work.
⚠️ Note: The interface may change in new versions of Android TV. If you don't see the "Cast" option, try searching through your settings by entering "Cast" or "Cast" in the search bar.
Setting up Wi-Fi Direct in the DEXP menu (Linux and other OS)
DEXP models running on operating systems like Linux Or the manufacturer's own shells, they have a more traditional settings menu. Here, the function is often located in a separate section called "network connections." The search algorithm may differ, but the logic remains the same: look for the section responsible for wireless connections.
Click the button Menu on the remote control and go to the section Net or NetworkIn the list that opens, select Wi-Fi DirectIf there is no such item immediately, look for a sub-item Wi-Fi settings or Wireless networkIn some cases, it is necessary to switch the Wi-Fi module operating mode.
Once enabled, the TV will begin searching for devices or become visible to them. You may see a connection confirmation prompt when attempting to pair a new device. This is a standard security procedure to prevent unauthorized access to your screen.
It is worth noting that in older DEXP firmware versions this function could be called Wireless Display or Anyview CastIf you see names like these, feel free to choose them—they're similar to the technology you're looking for. The interface may not be as smooth as Android, but the functionality remains the same.
What should I do if the Wi-Fi Direct option is not in the menu?
In some budget DEXP models, this feature may be hidden by software or absent. Try updating your TV's firmware via USB or contact the manufacturer's support team.
Using the DEXP Multi-Screen app for broadcasting
If standard search methods fail, the manufacturer often offers its own software. For DEXP TVs, it's important to use aggregator apps or proprietary utilities that can be downloaded from the TV's app store or installed manually via APK file.
One of the popular solutions is the application AnyCast or built-in application Multi-ScreenAfter launching such an app, the TV goes into connection standby mode. On your smartphone, you need to launch a similar app or use the "Screen Casting" feature in the Android/iOS system settings.
The advantage of using specialized apps is expanded functionality: the ability to control the mouse cursor from your phone, high-quality audio streaming, and support for various codecs. This is especially relevant for models where the basic protocol implementation is unstable.
When installing third-party software, make sure you download it from trusted sources to avoid malware. There are numerous such utilities available in Android TV app stores (Google Play), so choose those with high ratings and positive reviews.
Compatibility table and common connection problems
Not all devices support the same data transfer standards, which can lead to connection errors. Below is a table to help you navigate potential issues and solutions for various use cases.
| Device type | Supported protocol | Possible problem | Solution |
|---|---|---|---|
| Android Smartphone | Miracast / Chromecast | The TV is not visible | Enable geolocation on your phone |
| iPhone / iPad | AirPlay (rare) / App Cast | Unstable image | Use a proxy application |
| Windows laptop | Miracast | Cursor delay | Update Wi-Fi adapter drivers |
| Huawei tablet | Wireless Projection | Black screen with sound | Reduce output resolution |
Particular attention should be paid to the drivers on connected devices, especially laptops. Outdated Wi-Fi adapter software may not work correctly with the new encryption standards used. DEXP.
Problems can also arise due to airwave congestion. If there are multiple wireless networks nearby, the signal may be interrupted. In this case, rebooting the router (if it's being used as a bridge) or changing the broadcast channel may help.
Resolving issues with visibility and connection stability
It's quite common for a DEXP TV to be turned on and the feature activated, but the smartphone "can't detect" it. First, check to see if your antivirus or firewall software is blocking the detection of new devices. Sometimes, temporarily disabling the protection is enough to check.
The second important aspect is the TV's software version. Manufacturers periodically release updates that fix Wi-Fi module bugs. Go to the menu Support → Software Update and check for new versions. If automatic updates don't work, you can download the file from the official website and install it via USB.
⚠️ Note: Menu interfaces and item names may vary depending on the model year and firmware version. Always refer to the latest manual for your specific DEXP series.
If all else fails, try resetting your TV's network settings. This will reset the Wi-Fi module to factory defaults and may resolve software conflicts. After the reset, you'll need to re-enter your home network password if you're using router mode.
☑️ Connection diagnostics
Security when using direct connections
Use of technology Wi-Fi Direct This involves creating an open or semi-open access point. When you activate search mode, your TV becomes visible to all devices within range. While starting a broadcast usually requires confirmation from the remote, basic visibility is maintained.
Don't leave this feature enabled permanently unless you plan to use it soon. This not only improves security but also saves the TV's processor resources, preventing possible overheating of the communication module during prolonged standby mode.
When connecting to public networks or using guest mode, make sure you're not broadcasting sensitive information. Screen mirroring shows everything that's happening on your phone, including notifications and private messages.
Is it possible to hack a TV via Wi-Fi Direct?
Theoretically, vulnerabilities exist in any network protocol, but casual hacking requires physical proximity and specific software. The risk is minimal when using connection confirmations.
FAQ: Frequently Asked Questions
Why doesn't my DEXP TV see my phone in the Wi-Fi Direct list?
