Modern multimedia capabilities allow you to transform any Smart TV into a powerful entertainment center, streaming content directly from a mobile device. Owners of the equipment DEXP often face the need to display images from iPhone to a large screen for comfortable viewing of movies or photos. The synchronization process is based on the use of a local wireless network and special data transfer protocols, such as AirPlay or DLNA.
The key to a successful connection is proper configuration of the router and the TV itself, as iOS devices have high connection stability requirements. Wireless 4K video transmission requires a network bandwidth of at least 25 Mbps. In this article, we'll cover all connection methods, potential issues, and solutions in detail so you can enjoy content without delay.
Before you begin setting up, make sure your TV is DEXP Supports Smart TV and has a built-in Wi-Fi module. If the model is in the budget segment and doesn't have a smart operating system, you'll need an additional media player or set-top box with AirPlay support.
Preparing equipment and network
The first and most important step is to ensure that both devices are on the same network. Your iPhone and TV DEXP must be connected to the same Wi-Fi access point. Using a guest network or different frequencies (for example, 2.4 GHz for one and 5 GHz for the other) may result in the devices simply not seeing each other in the list of available ones.
Make sure the wireless connection is enabled on your TV. To do this, press the button on the remote control. Settings or go to the settings menu where you need to select a section NetThis displays your connection status and network name. If your TV is connected via a LAN cable and your phone via Wi-Fi, this may work in some cases, but it's best to use the same connection type for stability.
- 📶 Make sure both devices are within range of the router's signal.
- 🔄 Restart your router if your network is unstable or your speed is slow.
- 📱 Update iOS on your iPhone to the latest available version for best compatibility.
Particular attention should be paid to network security. If AP Isolation is enabled on the router, devices on the network will not be able to communicate with each other, even if they are on the same network. This feature usually needs to be disabled in the router settings via the web interface.
Using the built-in AirPlay feature on DEXP
Many modern TV models DEXP, running on the operating system Android TV or Linux with support for the relevant services, have built-in protocol support AirPlay 2This is a native Apple technology that allows you to stream images and sound without installing additional software.

However, third-party apps from the App Store provide the most stable performance.
One of the most popular solutions is the application Cast to TV or Web Video CasterThe principle of their operation is that the application scans the local network, finds a Smart TV and establishes a connection via the protocol DLNA or ChromecastYou need to download such an app on your iPhone, open a video file or movie link, and click the "Stream" button.
Unlike AirPlay, it often only allows you to cast a media file, rather than the entire screen. This allows you to use your phone for other tasks while watching a movie on your TV. In the app menu, select your TV. DEXP from the list of found devices. If the search doesn't yield any results, try manually entering the TV's IP address, which can be found in the "About TV" section of its settings.

- 🎮 Allows you to control playback from your phone as if it were a remote control.
- 🌐 Works even if the TV does not have a built-in browser.
Setting up DLNA for viewing photos and videos
Protocol DLNA (Digital Living Network Alliance) is a standard for sharing multimedia on a home network. On TVs DEXP This feature is often implemented through the built-in media player. To use this method, you need to install a server app on your iPhone, such as FileBrowser or use built-in iOS tools with file manager support.
After installing the application and connecting to the same network, launch the application on the TV Media or PhotoIn the signal sources, select your local network or your iPhone's name. The TV will display the folder structure available for playback. You will be able to view high-resolution photos or play videos.
The advantage of DLNA is that the TV decodes the video stream itself, offloading the load from the phone's processor. This is especially important for viewing large 4K HDR files. However, this method is not suitable for streaming app or game interfaces, as only the content is transmitted.
Why can't DLNA see files?
Often, the problem lies in codec formats. The TV may not support the AC3 audio track in a video file, even if the MKV container itself is readable. In this case, converting the file or using a player app on the TV itself, such as VLC, will help.
Troubleshooting and fixing connection errors
Despite the standardization of technologies, users often encounter situations when the TV DEXP The device isn't showing up in the iPhone device list. The most common cause is out-of-sync IP addresses or network cache. Try performing a hard reset of the router by unplugging it for 30 seconds.
Another common issue is outdated software. Check for firmware updates for your TV. Go to Settings → About TV → Software UpdateNew firmware versions often contain compatibility fixes for new versions of iOS.
| Problem | Possible cause | Solution method |
|---|---|---|
| TV not found | Different Wi-Fi networks | Check the SSID on both devices |
| The image is lagging | Weak Wi-Fi signal | Move the router closer or switch to 5 GHz |
| There is no sound on the TV | DRM blocking | Use a wired connection or HDMI |
| Black screen | HDCP error | Reboot the device chain |
If the issue is system-related, try resetting the network settings on your iPhone. Go to Settings → General → Transfer or reset iPhone → Reset → Reset Network SettingsThis action will delete saved Wi-Fi passwords, but often resolves issues with device visibility on the local network.
☑️ Connection diagnostics
Alternative ways to connect without Wi-Fi
If a wireless connection is impossible or the signal quality is poor, you can always turn to wired methods. For iPhones, using an adapter remains a viable option. Lightning to HDMI (or USB-C to HDMI (for new models). This ensures signal transmission in the highest quality without compression or delays.
You can also use external media players such as Apple TV, Chromecast or Android TV set-top boxes connected to the TV's HDMI port DEXPIn this case, the TV simply acts as a monitor, and the set-top box handles all the connection to the iPhone, which often produces a more stable result than the built-in Smart functions of budget TVs.
Using a cable ensures you're not dependent on airtime congestion from neighboring routers. It's ideal for watching high-bitrate movies or giving presentations where every second and pixel counts.
⚠️ Important: When purchasing a Lightning to HDMI adapter, look for MFi certification. Cheaper alternatives may not transmit images with protected content (Netflix, iTunes Movies) due to the HDCP protocol.
