This is especially convenient when watching videos, sharing photos, or playing mobile games on a large screen.
The synchronization process is based on standard data transfer protocols such as Miracast or DLNA, which are built into the operating system Android TV, used by most Dexp models. You don't need complicated router settings or paid software. Simply connect both devices to the same local network, and you can start streaming instantly.
In this article, we'll take a detailed look at all available wireless connection methods, from built-in system features to third-party apps. We'll also address signal stability and address common issues users encounter when attempting screen sharing.
Preparing equipment and checking the network
Before you begin setting up, make sure your TV is Dexp and the smartphone are connected to the same Wi-Fi access point. This is a fundamental requirement for the technology to work. DLNA and screen mirroring protocols. If your router broadcasts the network on 2.4 GHz and 5 GHz frequencies with different names, it's best to select one for both devices to avoid conflicts.
Check your TV's software version. Manufacturers periodically release updates that improve the stability of wireless modules. Go to the menu Settings → Device → About → System update and start searching for new versions. Having the latest firmware often solves issues with your smartphone not appearing in the list of available devices.
⚠️ Attention: If your router has a "Guest Network" feature, do not connect devices to it. In guest mode, devices are isolated from each other and cannot exchange data within the local network.
For smartphones based on Android It's also a good idea to update Google Play system services and the Google Home app, as they often act as intermediaries when transferring media files. Make sure Bluetooth is enabled on your phone, as some models Dexp use it for the initial handshake before establishing the main data transmission channel.
Using the built-in screencasting feature
The most universal way to display images from your smartphone on your TV Dexp - using the native function of the operating system. In the environment Android This option may be called differently depending on the shell manufacturer: “Broadcast”, “Smart View”, “Wireless Monitor” or “Screen Projection”.

- 📱 On Xiaomi and Redmi the function is called Broadcast in the control menu.
- 📱 On Huawei and Honor, use the item Projection in the control center.
- 📱 On a stock Android, look for the option Broadcast in quick settings.
Image quality directly depends on the strength of the Wi-Fi signal. If you notice audio and video desynchronization or artifacts, try moving closer to the router. Miracast, used for mirroring, is sensitive to interference and requires a stable communication channel.
☑️ Pre-broadcast check
Broadcast for iPhone owners (AirPlay)
Device owners Apple can use technology AirPlay, which is supported by many modern TV models Dexp Powered by Android TV, this not only allows you to mirror your screen but also stream videos, photos, and music with minimal latency and high quality.

This method is convenient because it doesn't require the smartphone screen to be constantly on and allows you to manage your playlist.
The table below shows a comparison of the main connection methods based on key parameters:
| Method | Delay | Quality | Battery load |
|---|---|---|---|
| Miracast (Screen Casting) | Low | High | High |
| DLNA (Media files) | Absent | Original | Average |
| YouTube Cast | Minimum | Maximum | Low |
| AirPlay (Apple) | Low | High | High |
Third-party applications for connection
If standard methods don't work or the functionality isn't sufficient, you can use third-party solutions. Application TV Cast or Web Video Caster Allows you to stream video from browsers that don't have built-in Chromecast support. This is useful for watching online movies through a mobile browser.
For gamers who want to run a mobile game on a big screen with minimal lag, there are specialized utilities like GameStreamerHowever, for a comfortable gaming experience, it is still recommended to use a wired connection or low-latency technologies, as input lag may be noticeable over Wi-Fi.
When installing third-party software, pay attention to the permissions it requests. The app only needs access to the local network and media files. If an app requires access to contacts or the microphone without an obvious need, it's best to avoid using it for security reasons.
What to do if the TV doesn’t see the phone?
Make sure AP Isolation is disabled on your router. This setting prevents devices on the network from seeing each other. Also, try rebooting the router by completely unplugging it for 10 seconds.
Troubleshooting connection issues and errors
One of the most common issues is when the TV stops detecting the phone after updating the router or changing the password. In this case, you need to "forget" the Wi-Fi network on both devices and reconnect them using the latest information. Resetting the network settings on the smartphone often helps.
If the image is choppy or has low resolution, check the Wi-Fi network load. Downloading large files on other devices on the network can choke the video stream. In such cases, you can prioritize traffic for Smart TV in your router settings (QoS function), if supported.
⚠️ Attention: When using the "Screen Cast" feature in landscape mode on your phone, black bars may appear on the sides of the TV if the video's aspect ratio doesn't match the TV's screen aspect ratio. This is normal system behavior.
In some cases, antivirus software on your phone or a firewall on your router may block ports that are necessary for operation. MiracastTry temporarily disabling protection for diagnostic purposes. If the issue is resolved, add your TV and media services to the exceptions list.
Why is my Dexp TV not showing up in the list of available devices?
Most often, the problem lies in the devices being on different subnets (for example, one connected to guest Wi-Fi and the other to the main Wi-Fi) or client isolation being enabled on the router. Also, check if there are any time limits or parental controls enabled on the TV.
Is it possible to connect a phone to a TV without Wi-Fi?
Without a wireless network, you can only use a wired connection via a USB-C to HDMI adapter (for Android) or Lightning to HDMI adapter (for iPhone). Some models also support a USB cable connection for file transfer, but not for live screen sharing.
Does phone connection affect internet connection quality?
Yes, when using screen sharing (Miracast/AirPlay), your phone actively uses Wi-Fi to transmit the video stream, which can slow down page loading speeds or the performance of other apps on your smartphone. When using the Cast feature (YouTube), the load on your phone is minimal.
How to improve picture quality over a wireless connection?
Use a router that supports Wi-Fi 5 (ac) or Wi-Fi 6 (ax) and connect devices to the 5 GHz frequency. Make sure there are no thick walls or strong sources of interference, such as microwave ovens, between the TV and the router.
