Process broadcasts (screen mirroring) based on Wi-Fi Direct or Miracast protocols, which are built into most modern operating systems. DEXPAs a manufacturer, Samsung is actively implementing support for these technologies in its Smart TVs, but the user interface may vary depending on the model year and firmware version. In this article, we'll cover all the connection details, potential issues, and solutions.

Before you start setting up, make sure that your router is working stably and Wi-Fi module is active on the TV. Picture quality directly depends on the speed of the wireless connection and the absence of interference. If you plan to stream high-definition video, we recommend using the 5 GHz frequency if your router and TV support this range.

Preparing equipment and network

The first step is to properly organize the local network. Both devices - the smartphone and DEXP TV — must be connected to the same access point. If you have a dual-band router, it's best for both devices to operate on the same frequency, although modern routers can correctly route traffic between 2.4 GHz and 5 GHz.

Check the operating system version on your mobile device. Versions 5.0 and above are considered current for Android, and 10.0 and above for iOS. Outdated software may not support the required codecs or protocols. DLNA, which will make it impossible to detect the TV in the list of available devices.

⚠️ Note: The menu interface may vary depending on the specific DEXP model and year of manufacture. If you don't see the options described, please refer to the user manual or update your TV's software via USB.

Broadcasting from an Android smartphone

For owners of devices based on Android The process is simplified to the maximum extent thanks to the integration of Google Cast and Miracast technologies. The standard notification shade (quick access panel) often features a button Broadcast, Smart View (on Samsung) or Projection (on Xiaomi/Huawei). Pressing this button starts a search for available displays.

When yours appears on the list DEXP TV, select it. A connection request may appear on the TV screen, which you'll need to confirm with the remote. After that, the entire image from your smartphone will be copied to the big screen. This is convenient for sharing photos, videos from your gallery, or even games.

If you can't find your TV using standard tools, you can use the app Google HomeIt automatically detects Chromecast-compatible devices, which include many Smart TVs. In the app, select your TV and press the button. Broadcast your screen.

What to do if the broadcast button is hidden?

On some Android skins (such as MIUI or ColorOS), this feature may be hidden in the "More" menu (the three dots or gear icon in the corner of the notification shade). It may also be called "Wireless Monitor" or "Multi-screen Interaction."

Transmission quality depends on the smartphone's processor power and Wi-Fi speed. Input lag is possible when playing heavy 4K content, so this method may not be suitable for fast-paced games, but it's ideal for watching movies.

Third-party streaming apps

If built-in methods don't work or require complex configuration, universal utilities come to the rescue. One of the most popular solutions is the app TV Cast or Web Video CasterThey allow you to stream not only photos and videos from your gallery, but also web page content directly to your TV's browser.

Their operating principle is often based on a protocol DLNAYou install the application on your phone, and on your TV (in the applications section) you launch the corresponding receiver (for example, MediaShare (or built-in media player). The phone sees the TV as a network storage or rendering device.

For streaming from specific services (YouTube, Netflix) it is better to use the built-in button Cast (Wi-Fi icon with a corner) within the video hosting app itself. In this case, the phone acts only as a remote control, and the TV downloads the video directly from the internet, saving battery life and ensuring better quality.

⚠️ Note: Free versions of third-party apps often contain ads that can obscure the image on your TV. For a more comfortable experience, consider purchasing the premium version or using open-source alternatives.

Diagnosing problems and delays

The most common problem with wireless streaming is desynchronization of audio and video or intermittent image flickering. This almost always indicates Wi-Fi channel instabilityTry rebooting your router and disconnecting other devices that consume a lot of traffic (torrents, downloads).

Another common mistake is using different networks. Make sure your phone isn't using mobile data (4G/5G) while your TV is using Wi-Fi. They should be in the same subnet address space. Also, check that AP Isolation isn't enabled on your router, which prevents devices from seeing each other.

If you see a picture but no sound, check the audio output settings on your smartphone. Sometimes the system continues to output sound through the phone's speaker by default, even when the video is playing on the TV. In this case, you need to select DEXP TV as an audio output device in Bluetooth or media settings.

Why is the 4K image lagging?

Streaming 4K over Wi-Fi requires a huge amount of bandwidth. If the router is old (802.11n standard) or located far away, the system will automatically downgrade to 720p or 1080p, or buffer frames, causing lag.

Frequently Asked Questions

Is it possible to display a screen on DEXP without a Wi-Fi router?

Yes, if your TV and smartphone support Wi-Fi Direct technology. In this mode, the devices connect directly to each other, bypassing the router. However, this connection may be less stable and the functionality limited.

Why is my DEXP TV not visible in the list of devices?

Check that Miracast/AirPlay is enabled in the TV menu. Make sure both devices are on the same network. Also, try temporarily disabling your antivirus or firewall software on your phone if they're blocking local connections.

Does broadcasting affect my phone's battery life?

Yes, wireless video streaming is a power-intensive process. Your smartphone's screen must be lit (unless you're using audio-only mode), and the Wi-Fi module must be constantly transmitting data. It's recommended to keep your phone charged while watching long movies.

Does DEXP support audio streaming separately?

In most cases, the full A/V (Audio/Video) stream is transmitted. It's difficult to output just the audio to the TV speakers via Miracast; for this, it's better to use Bluetooth pairing if the TV supports the A2DP profile.
