Using a smartphone as a remote control or media source for a TV has become standard, but DEXP owners often encounter difficulties when trying to sync their iOS device with their TV. The main problem is the lack of native support. Apple AirPlay This problem exists in most budget TVs' default firmware, forcing users to seek workarounds. However, modern solutions allow for wireless streaming of content using only a home Wi-Fi network.
In this guide we will cover all the working methods of connection iPhone With DEXP Smart TV, from built-in features to third-party apps. You'll learn how to set up screen mirroring, transfer photos or videos from your gallery, and the nuances of protocols. DLNA And Miracast It's worth considering. Proper settings will ensure a stable picture and sound without lag.
Before you begin setup, make sure both devices are on the same local network. This is critical, as the router acts as an intermediary, transmitting data packets between the smartphone and TV. If your router has two networks (2.4 GHz and 5 GHz), it's best to have both devices connected to one of them, although modern routers with the feature Smart Connect This is not always necessary.
Preparing equipment and checking the network
The first step in the setup process is to thoroughly check your network environment. Make sure that your DEXP connected to the internet and has an active network connection. Go to the TV menu, select the section Net and check the connection status. If you're using a wired connection, there are usually fewer problems, but for wireless broadcasting, the Wi-Fi module must be working correctly.
On iPhone You also need to enable Wi-Fi. iOS can sometimes switch to a mobile network if the router's signal is weak, which will interrupt the connection to the TV. Open Settings and make sure the box next to your network name is checked. It's also worth checking that "Data Saver" mode isn't enabled, as this can block local device detection.
⚠️ Attention: Some routers have a feature called "AP Isolation." When enabled, devices on the Wi-Fi network won't see each other. To connect your iPhone to your TV, you'll need to disable this feature in your router settings.
Checking software versions is another important step. On your TV, go to Settings → About → Software Update and make sure you have the latest available version installed. Older firmware may lack the necessary components to work with Apple protocols. Similarly, update your smartphone's iOS to the latest version.
Using the built-in AirPlay feature on DEXP
Many modern models DEXP, especially those that run on Android TV or have licensed certificates, support the protocol AirPlay 2 or similar. This is the easiest method and doesn't require any additional software. To check if this feature is available, look for an app called "AirPlay," "Screen Mirroring," or "Wireless Display" on your TV's home screen.
If such an app is found, launch it. A code or name of the device waiting to connect will appear on the screen. Now take iPhone, swipe down on the Control Center (swipe down from the top right corner or from the bottom up, depending on the model). Press the button Screen mirroring (two rectangles).
Your TV should appear in the list of available devices. Select it. If a confirmation code appears on the TV screen, enter it on your iPhone. After this, the image from your smartphone will be copied completely to the big screen. Picture quality in this mode depends on your Wi-Fi channel speed and airtime.
It's worth noting that not all DEXP models support this protocol at the hardware level. If the built-in app is missing or unstable, don't despair—there are alternative software solutions.
Streaming via third-party apps on your TV
If native support for Apple devices is missing, apps from the store come to the rescue. Google Play Store on TV. The most popular and functional solution is an app AirScreen or AirPinThey emulate an AirPlay receiver, making the iPhone "think" it is connecting to an Apple device.
Download the selected app to your TV via the app store. After installation, launch it and press the button. Start or GoThe app will create a virtual device that will be visible to your smartphone. In some cases, you may need to register or view an ad to activate this feature.
After launching the emulator on the TV, repeat the procedure on the iPhone: open Control Center → Screen Mirroring → select the name that appears in the app on the TV. Now your DEXP It functions as a full-fledged AirPlay receiver, allowing you to stream not only videos but also games, presentations, and your desktop.
⚠️ Attention: Free versions of emulator apps often have session time limits or contain banner ads. For permanent use, consider purchasing the full version directly from the app interface on your TV.
An alternative is to install DEXP apps directly if the manufacturer offers them in its own store. However, third-party solutions from Google Play are usually updated more frequently and have better compatibility with newer iOS versions.
Transfer photos and videos via DLNA and Cast
To transfer media content (photos, videos, music), it is not necessary to duplicate the entire smartphone screen. Protocol DLNA (Digital Living Network Alliance) allows you to stream specific files directly to your TV's player. This reduces the load on the iPhone's processor and saves battery life.
Most DEXP TVs have a built-in media player that supports DLNA. Make sure the Media or Gallery app is running on your TV. On iPhones, DLNA access is difficult to achieve using standard tools, so you'll need a third-party app, such as Cast to TV, LocalCast or Web Video Caster.
Install the app on your iPhone, open the desired file (video or photo), and tap the cast button (the rectangle icon with Wi-Fi waves). Select your TV from the list. DEXPThe file will start playing on the TV, and the smartphone can be used for other tasks or locked.
Why does the video jerk when broadcasting?
Video stuttering is often caused by insufficient Wi-Fi bandwidth. Try lowering the quality of the streaming file or moving the router closer to the TV. Also, make sure no other data is being stored on the TV's flash drive.
The advantage of DLNA is that the TV decodes the video itself. This is especially useful for high-resolution files (4K), which can be difficult to play using simple screen mirroring. However, the file format must be supported by the TV's codecs.
Setting up mirroring via Chromecast
Many Smart TV DEXP are equipped with a built-in module Chromecast built-inAlthough this is Google's technology, it works perfectly with iPhones using apps that support this standard. Unlike AirPlay, it doesn't broadcast the screen, but rather a stream of content from a specific app.
On your iPhone, open the app you want to watch on TV (YouTube, Netflix, Google Photos, or the Chrome browser). Find the cast icon (a square with waves) in the corner of the app interface. Tap it and select your DEXP TV from the list.
It's important to understand the difference: when using Chromecast, your phone only acts as a remote control. If you minimize the YouTube app on your iPhone, the video will continue playing on your TV. However, if you turn off your phone's screen, the streaming will stop because the control will disappear.
To mirror an iOS screen via the Chromecast protocol, you will need an intermediary app, such as Replica or Streamer for ChromecastThey create a video stream from the iPhone screen and send it to the TV's network address.

Connection Method Comparison Table
To help you choose the right method, we've prepared a comparison table of the main methods. It will help you quickly navigate depending on your goals: whether you just need to show a photo or run a game on a larger screen.
| Method | Quality | Delay | Complexity |
|---|---|---|---|
| Built-in AirPlay | High | Low | Low |
| AirScreen (Emulator) | Medium/High | Average | Average |
| DLNA (Files) | Maximum | Absent | Low |
| Chromecast Cast | High | Low | Low |
| HDMI adapter | Maximum | Absent | Low |
As the table shows, a wired connection via an HDMI adapter provides the best results, but requires additional equipment. Wireless methods are convenient, but depend on the quality of your home network.
Solution and troubleshooting
Even with proper setup, errors may still occur. If the TV doesn't detect your iPhone, try restarting both devices. Often, the issue lies in the network service cache, which is cleared after a restart. Also, make sure your router isn't using MAC address filtering.
If you have a picture but no sound, check the sound settings on your TV. Sometimes, when switching sources, the sound remains on the previous channel. You can also select the audio output device in the iPhone's Control Center by tapping the audio icon in the music controls.
⚠️ Attention: DEXP TV interfaces may vary depending on the year of manufacture and display model. If you don't see the menu items described, consult the official manual for your specific model, as the location of the network settings may vary.
If you're constantly experiencing connection drops, try changing the Wi-Fi channel on your router. In apartment buildings, the airwaves are often congested, and switching to a less congested channel (for example, from 1 to 6 or 11) can dramatically improve connection stability.
Frequently Asked Questions (FAQ)
Is it possible to connect an iPhone to DEXP without Wi-Fi?
