Modern multimedia capabilities make it possible to transform any TV into a powerful entertainment center using just a smartphone and a wireless connection. Owners of DEXP devices often wonder how to stream image and sound without unnecessary cables that clutter the space and restrict freedom of movement. Fortunately, most modern models, regardless of operating system, support wireless content streaming standards.
The process of synchronizing the gadget and the TV panel is based on protocols Miracast, DLNA or proprietary solutions like AirPlay. Understanding the differences between these technologies will help you choose the best method for your needs: whether it's displaying photos from your gallery, playing videos, or copying your mobile device's entire screen to a larger display.
In this guide, we'll detail the steps for various use cases. We'll cover setup details for Android and iOS smartphones, as well as address potential issues with connection stability and signal quality.
Preparing equipment and network
Before starting setup, ensure both devices are in the same local network connection conditions. This is a fundamental requirement for most discovery and data transfer protocols to work. If your router broadcasts on both 2.4 GHz and 5 GHz frequencies, make sure your phone and TV are connected to the same frequency band, as some older router models can isolate clients on different bands from each other.
Check that the software on both devices is up to date. Manufacturers regularly release updates that fix bugs in modules. Wi-Fi and improving compatibility with new versions of mobile operating systems. Go to the DEXP TV settings menu and find the section for system updates or product information.
⚠️ Important: If your router uses AP Isolation mode, devices will not see each other on the network. This mode is often enabled on guest networks in hotels or cafes, but at home, it should be disabled in the router settings.
For stable transmission of high-definition video streams The recommended Wi-Fi connection speed should be at least 20-30 Mbps, especially if you plan to stream 4K content. A weak signal can lead to audio and video desynchronization or compression artifacts.
Using the built-in Screen Mirroring feature
The most universal method is to use wireless display technology. On DEXP TVs, this feature may have different names depending on the firmware version: Anyview Cast, Miracast, Wireless Display or simply "Broadcast." You need to launch the corresponding app on your TV through the signal source menu or find it in the list of installed programs.
After activating standby mode on the big screen, go to your smartphone settings. On Android devices, the path usually looks like this: Settings → Connections → Broadcast or Settings → Display → Wireless MonitorThe interface may differ depending on the phone manufacturer's shell (MIUI, OneUI, ColorOS).
Your smartphone will begin searching for available devices within range. When your DEXP model appears in the list, tap it to pair. A connection confirmation prompt may appear on the TV screen, which you'll need to accept using the remote.
- 📱 Make sure Wi-Fi is turned on on your phone, even if you use mobile data for other tasks.
- 📺 On some DEXP models, you need to manually select the "Wireless" or "Screen Share" signal source.
- 🔄 If the connection drops, try restarting the Wi-Fi module on both devices.
Once paired successfully, your phone's image will be mirrored on the TV. This allows you to run any apps, browsers, or games while displaying them on the big screen. However, keep in mind that this mode may drain your phone's battery and heat up faster.
☑️ Check before connection
Broadcasting via the YouTube app
The most popular use case is watching videos. This eliminates the need to mirror the entire smartphone screen, saving battery life and allowing the phone to be used for other tasks while watching. Google Cast It's built right into the YouTube app and works more reliably than the system's screencasting.
Open the YouTube app on your DEXP TV. If you have a Smart TV, the app should be preinstalled. If not, you can find it in the app store or use the built-in browser to access the web version, although functionality may be limited. On the YouTube app's main screen, you'll see an activation code or simply a pending connection.
Now, pick up your smartphone and open the same video you want to watch. In the upper right corner of the video player, tap the rectangle icon with waves (broadcast). Select your DEXP TV from the list that appears. The video will start playing on the TV, and your phone will act as a remote control.
| Parameter | Screen Mirroring | YouTube Cast |
|---|---|---|
| Phone CPU usage | High | Low |
| Possibility of using a telephone | No (screen is busy) | Yes (you can work) |
| Image quality | Depends on the signal | Maximum (stream from server) |
| Battery consumption | Fast | Economical |
The advantage of this method is that the TV downloads the video stream directly from the internet, bypassing the phone. This reduces the load on the Wi-Fi channel and eliminates delays associated with on-the-fly image encoding.
Connecting iPhone and iPad (AirPlay)
Apple device owners often face difficulties because the iOS ecosystem uses a protocol AirPlay, which isn't always natively supported by DEXP TVs. However, many modern models have built-in AirPlay 2 support or the ability to install corresponding apps.
Check the app list on your TV. If you see "AirPlay," "Apple HomeKit," or something similar, launch it. Otherwise, you can find third-party solutions in the TV Store (if you have an Android TV), such as AirScreen or AirPin, which emulate signal reception from Apple devices.
After installing and launching the emulator on your TV, open Control Center on your iPhone (swipe down from the upper-right corner or up from the bottom on older models). Tap the "Screen Mirroring" button (two rectangles). Select your TV from the list.
⚠️ Please note: When using third-party emulators, a slight image delay (latency) may occur. This is normal for wireless technologies, but may interfere with fast-paced games.
If automatic discovery isn't working, make sure multicast traffic isolation isn't enabled on your router. The AirPlay protocol actively uses broadcast requests to find devices on the network, and blocking this traffic makes the TV invisible to the iPhone.
What to do if AirPlay isn't working?
Make sure IGMP Snooping is enabled on your router. Without proper processing of multicast packets, discovering Apple devices may not be possible. Also, try temporarily disabling your router's antivirus software, if available.
Stream photos and videos via DLNA
For viewing the media library stored in the smartphone memory, the technology is ideal DLNAIt allows the TV to view the phone's shared folders as network storage. Unlike Miracast, it transmits the files themselves, not the screen's video stream, providing better quality and the ability to rewind without buffering.
On your DEXP TV, launch the Media or Gallery app. Select Devices or Network from the source list. Now you need to set up your phone. On Android, you can use the built-in Cast feature in the Gallery app or install a file manager with DLNA support, such as VLC or BubbleUPnP.
In the player app on your phone, find the video or photo you want, tap the "Cast" button, and select your TV. The file will begin playing on the big screen. This method is especially convenient for viewing family albums or pre-downloaded movies.
- 📁 DLNA supports video, audio and image playback.
- 🎚️ Rewind and volume are controlled using the TV remote control.
- 🔋 You can lock your phone or use it for other tasks while browsing.
It's important to note that the file format must be supported by your TV. If your TV doesn't have a built-in codec for a particular video format (such as HEVC or MKV with a specific audio track), the file may not play or may play without sound.
Troubleshooting connection issues
Despite its apparent simplicity, wireless connections can be fickle. If your DEXP TV can't detect your phone or the connection keeps dropping, first check the frequency range. Congestion on the 2.4 GHz channel from neighboring routers can cause interference and packet loss.
Try rebooting your router by completely unplugging it for 10-15 seconds. This will clear the device's cache and force it to select a less noisy channel. It's also worth checking if your router has a limit on the number of connected devices (MAC filtering).
In some cases, resetting the network settings on your phone can help. This will delete saved Wi-Fi passwords and Bluetooth settings, so be prepared to re-enter them. After the reset, pair the phone with your TV again.
If the issue persists only with one specific app, try clearing its cache or reinstalling it. Software conflicts on the smartphone are a common cause of unstable broadcast protocols.
Why is my DEXP TV not showing up in the list of devices?
Most likely, the devices are on different subnets or VLANs. Check that both devices are connected to the router's main SSID, not the guest network. Also, make sure a signal-receiving app (such as Anyview Cast) is running on the TV.
Is it possible to connect a phone via Wi-Fi Direct without a router?
Yes, many DEXP models support Wi-Fi Direct. This feature connects your phone directly to your TV's Wi-Fi module, creating a local network without a router. This is useful if your router is far away or unavailable.
Does phone connection affect internet speed?
When using Screen Mirroring, traffic flows within the local network and doesn't consume internet bandwidth. However, when streaming (YouTube, online cinemas), the TV consumes traffic directly, which can reduce speeds on other devices if you have a low data plan.
