How to connect Xiaomi to a DEXP TV

Xiaomi’s modern smartphones and low-end but functional DEXP TVs allow you to create full-fledged multimedia systems right in your living room. Users often wonder how to display images from a mobile device to a large screen to watch movies, play games or show presentations. The process of synchronizing devices does not require deep technical knowledge, but has its own nuances depending on the chosen method.

There are several proven ways to connect your gadget to your display, from fully wireless technology to reliable cable connections. The specific method depends on your DEXP (Window TV) model and the Android version of your smartphone operating system. In this article, we will take a detailed look at each option so you can choose the one that suits your situation.

Wireless connection via Wi-Fi and Miracast

The most popular and convenient way to stream content is to use Miracast technology, which is built into most modern devices. To get started, make sure your Xiaomi smartphone and DEXP TV are connected to the same Wi-Fi network. If the router distributes the network at 2.4 GHz and 5 GHz, it is advisable that both devices are in the same range for stable data transfer without delay.

On DEXP TVs, the feature is often called “Wireless Display,” “Screen Mirroring,” or “Translation.” You need to find this app in the Smart TV menu and run it so that the TV goes into standby mode. On a Xiaomi smartphone, the path may differ depending on the MIUI or HyperOS shell, but it’s usually hidden in the notification curtain or in the connection settings.

Open the control center on your phone by swiping from top to bottom, and find the Translation or Project icon. If there is no icon, go to Settings → Connection and Sharing → Broadcast. Once you activate the search, the phone will start scanning the available devices. Once your DEXP appears on the list, click on it to pair.

  • 📺 Make sure the Miracast signal reception function is enabled on the TV.
  • 📶 Both devices must be on the same Wi-Fi network to be detected successfully.
  • ⚙️ On the TV, you may need to confirm the connection from the remote.
  • 🔄 When lagging, try to reduce the image quality in the broadcast settings.

It's worth noting that wirelessly connected, you can have a little image delay, which is critical for dynamic games, but it's not noticeable when watching videos. If the connection is cut, check if the router is insulated by client isolation mode, which prevents devices from seeing each other on the local network.

Using Chromecast Built-in technology

Many modern DEXP TVs feature built-in support for Google Chromecast technology, which allows you to stream content directly from apps like YouTube, Netflix or online cinemas without duplicating the entire screen of your smartphone, which saves your phone battery life and provides more stable picture quality.

To get started, run a smartphone app that contains a video or a photo. Find the broadcast icon — it looks like a rectangle with waves in the corner. Once you click, the phone will suggest a list of available devices. Select your DEXP TV from the list, and playback will begin on the big screen.

It's important to understand the difference between Miracast and Chromecast, which is that in the first case, the phone just duplicates its screen, in the second case, it acts as a remote control, and the video is downloaded by the TV directly from the Internet, which means that you can turn the app on the phone or even turn off the screen, and playback on TV will continue.

What to do if the broadcast icon does not appear?
The icon may not show if the phone and TV are on different Wi-Fi networks.Also make sure the app you're streaming from supports the Chromecast feature.Relatively, a Google Home or YouTube update on your smartphone is required.

If the built-in feature doesn’t work, you can use the Chromecast external console or an analog connected to the Chromecast. HDMI-It'll transform anyone, even the old one. DEXP, A full-fledged Smart-platform with support for all modern Google protocols.

Broadcasting through Third Party Applications (DLNA)

When embedded features are unstable or unavailable, third-party applications using the DLNA protocol come to the rescue. This standard allows you to share media between devices on the same network. To implement this method, you will need to install a special application on a Xiaomi smartphone, such as “AllCast”, “LocalCast” or “BubbleUPnP”.

Once you install the app, launch it and give you the necessary permissions to access files and the local network.The program will automatically find your DEXP TV in the list of available renderers. Select a video file, photo or music on your phone, click the send button and select the target device.

Advantage of use DLNA-The goal of the client is to support more file formats that may not be played by standard system tools, and these applications often have a built-in converter that on the fly recodes the stream into a format that is understandable for the TV, if you want to use the software. DEXP Does not support the original codec.

  • 📂 Support for a wide range of video formats (MKV, AVI, MP4).
  • 🎮 The ability to broadcast not only videos, but also photos with music.
  • 📱 The control of playback occurs entirely from the smartphone.
  • ⚠️ Free versions of apps may have time limits or advertising restrictions.

Maximum stability in the transmission of heavy 4K-file DLNA It is recommended to use a router with support for Wi-Fi 5 standard (AC) higher.

Some users prefer to use the computer as an intermediary, installing a media server (for example, DLNA Server) on a PC and sharing folders with movies. However, the direct method of Phone-Television is much more convenient and does not require the inclusion of additional hardware.

Connection via HDMI cable and adapters

If wireless connection is impossible due to poor signal or requires maximum image quality without compression, use cable connection. Standard Xiaomi smartphones rarely have a full HDMI port, so you will need a special adapter. Modern models with a USB Type-C port require a USB-C to HDMI adapter with support for MHL or SlimPort technology.

The connection process is as simple as possible: insert the adapter into the phone charging connector, connect HDMI-cable to the adapter and free end to the TV port DEXP. Switch the signal source to the TV in the appropriate mode (for example, HDMI 1 HDMI The image must appear automatically.

It is important to consider that not all Xiaomi models support video output via USB. Budget Redmi series and some Poco models may not have hardware support for video output. In this case, even with the cable connected, the screen will remain black.

Solving Connection Problems

Despite the simplicity of the procedure, users often face technical difficulties. DEXP Xiaomi phone doesn't see, and 90 percent of the time, it's done by rebooting the router, because it's a temporary crash in the table. ARP-Addresses can prevent devices from being found by each other.

Another common problem is desynchronization of sound and image, which is typical for wireless methods of transmitting data at low Internet speeds or congested Wi-Fi by neighboring networks, try to switch the router to a less busy frequency or move the devices closer to each other.

⚠️ Note: If you are connected through HDMI You have the image, but you don't have the sound, check the audio output settings in the "Sound" section of the TV. Sometimes you need to manually switch the sound source to the audio source. HDMI settings TV.

Also worth mentioning is the image format issue: Some older DEXP models may not properly display the picture from today's widescreen smartphones, cropping the edges. In the TV settings, look for "Screen Format" or "Aspect Ratio" and select "Just Scan", "Original" or "16:9" mode to remove the sprain.

If nothing works, try temporarily disabling the antivirus or firewall on the router if such features are activated there. They can block the ports required for the DLNA and Miracast protocols.

Optimizing the quality of image and sound

Once successfully connected, it is important to adjust the output image to get the best picture. DEXP TVs often activate aggressive power saving or dynamic contrast modes by default, which can distort colors. Go to the image settings and select Movie or User mode for more natural color reproduction.

For avid gamers who connect their phone to a TV to play on a big screen, it is critical to turn on Game Mode, which disables the extra post-processing of the frame, which significantly reduces the input delay. Without this mode, the movement of the cursor or character can feel “cotton”.

  • 🔊 For better sound, connect external acoustics via optical output or Bluetooth.
  • 📉 Turn off the noise cancellation of the image if the image appears to be soapy».
  • 🎮 Enable Game Mode to reduce input delays when playing games.

Keep in mind that long-term use of the smartphone in broadcast mode, especially over HDMI, can lead to heating of the device. it is recommended to remove the case from the phone or provide additional cooling to avoid trolling (decreased performance) and possible switching off of the screen.

💡

The quality of the final picture depends not only on the way of connection, but also on the correct settings of the TV matrix and the output resolution on the smartphone.

Why Xiaomi phone doesn't find DEXP TV over Wi-Fi
The most common problem is that devices are connected to different networks (for example, one to the guest, one to the main) or use the 2.4 GHz band for one and 5 GHz for another with the wrong router settings. Also, the Translation function can be blocked by the Wi-Fi security settings (AP Isolation).
Can I connect my phone to my TV without a smart TV?
Yeah, if the TV has one. HDMI-You're gonna need an adapter. USB-C to HDMI (for modern Xiaomi, or MHL-Adapter (older models) In this case, the phone will transmit the signal directly, turning the TV screen into a second monitor, regardless of the presence of Smart-functions.
Slow down video when broadcasting from your phone to DEXP, what to do?
