Modern technology allows you to forget about unnecessary wires that often get tangled underfoot and spoil the room's decor. Connecting your computer to a Dexp TV via Wi-Fi is a convenient way to stream content to a large screen without an HDMI cable. This method is especially useful when the PC and TV are located at a significant distance from each other, making a physical connection impossible or undesirable.
TV owners Dexp People often ask whether it's possible to display an image from the desktop or play a movie from a laptop's hard drive directly on the device's panel. The answer is yes: most modern models running the operating system Android TV or Linux, support wireless data transmission standards. This opens up wide possibilities for multimedia use of the device.
However, before you begin setup, it is important to understand that the quality of signal transmission directly depends on the stability of your home network. Wireless connection It's susceptible to interference, so to comfortably watch high-definition video, your router must support the 5 GHz frequency. In this article, we'll cover all available connection methods, from built-in Windows features to specialized apps.
Preparing equipment and network
Before proceeding with software settings, you need to make sure your equipment is ready for use. The first and most important requirement is that both devices are on the same local network. The computer and TV Dexp Both devices must be connected to the same router. If you use a wired connection on your PC and your TV via Wi-Fi, that's fine, but both devices must be on the same subnet.
Check your computer's operating system version. Windows 10 and 11 are best for native streaming features. We also recommend updating your TV's software to the latest version to eliminate any potential bugs in the wireless module. Go to the settings menu and find the software update option.
⚠️ Note: If your router broadcasts a network on 2.4 GHz and 5 GHz frequencies with different names (SSIDs), make sure both devices are connected to the 5 GHz network for maximum data transfer speed.
You can use the system's built-in tools to diagnose signal quality. Open a command prompt and enter a command to test the connection to the gateway. This will help ensure that data packets aren't being lost along the way.
ping 192.168.0.1 -tReplace the IP address with your router's address. If the response time is consistently low (less than 10 ms), the network is ready to handle heavy video streams. High ping times or packet loss indicate signal issues, which will result in delays in the image on the TV screen.
☑️ Check before connection
Using Miracast Technology in Windows
The easiest way to display an image from your computer to your Dexp TV is to use the built-in technology MiracastThis standard allows screen sharing without the need for additional routers, creating a direct Wi-Fi Direct connection, although it most often goes through the existing network infrastructure. In Windows, this feature is called "Projection."
To get started, make sure the signal reception app is running on your Dexp TV. Depending on your model and firmware version, it may be called Wireless Display, Screen Mirroring, Miracast or simply "Broadcast." It's usually found in the app list on the main panel or in the signal source menu (Input button).
On a Windows 10 or 11 computer, press the key combination Win + KThe "Connection" panel will appear on the right. Your Dexp TV should appear in the list of available devices. Click it, and the system will begin searching for drivers and establishing a connection.
- 📺 Select the "Repeat" mode to see an exact copy of your desktop on your TV.
- 🖥️ Select "Extend" if you want to use your TV as a second monitor for program windows.
- 🔒 Make sure a connection request notification appears on the TV screen and confirm it with the remote control.
If the connection is established but the image is choppy or has low resolution, try lowering the graphics quality in the projection settings. Click the "Projection Settings" link in the connection menu and select either quality or performance. It's also worth checking whether your Wi-Fi channel is being overloaded by neighboring networks.
Why is there no sound when connecting via Miracast?
Sometimes Windows doesn't switch the audio output device by default. Click the speaker icon in the system tray, select the output device, and select your Dexp TV in the list. If it's not there, update your audio and Wi-Fi adapter drivers.
Streaming media files via DLNA
If your goal is not to broadcast your desktop, but simply to watch a movie or photos stored on your PC's hard drive, it is better to use the technology DLNAIt allows the Dexp TV to view shared computer folders as network storage. This is a more stable method for watching videos, as buffering is more efficient.
In Windows, you need to enable media streaming. Open "Settings" → "Network & Internet" → "Status" → "Sharing Options." Turn on network discovery and file sharing. Then, search for "Media streaming options" in the system search bar and enable this feature.
| Parameter | Meaning for PC | Dexp TV Value |
|---|---|---|
| Connection type | Wi-Fi / Ethernet | Wi-Fi |
| Protocol | DLNA / SMB | DLNA support |
| Video formats | MKV, MP4, AVI | Depends on TV codecs |
| Stability | High | High |
After setting up your computer, open the media player app on your Dexp TV. It may be called "Media," "Gallery," or have a DLNA logo. You'll see your computer's name in the list of sources. Opening it will give you access to the "Videos," "Music," and "Pictures" folders.
It's worth noting that DLNA doesn't allow you to control content from your computer in real time, like with Miracast. Instead, you select a file on the remote, and the TV downloads it automatically. This frees up your PC's resources, allowing you to do other things while watching.
Broadcasting via Google Chrome browser
A universal solution for owners of Dexp TVs with technology support Chromecast built-in Or, if you have an external console, use the Google Chrome browser. This method works regardless of the Windows version and is even compatible with macOS, making it extremely popular among users.
To get started, open the Chrome browser on your computer. Make sure you're signed in to your Google account, although this isn't always a requirement. In the upper-right corner, click the three-dot menu and select "Cast."
In the window that opens, the browser will begin searching for available devices on the network. When your Dexp TV appears, you can choose what to stream: a specific browser tab, your entire desktop, or a specific media file. This is especially convenient for showing presentations or web pages.
- 🌐 Tab streaming is suitable for videos from sites that block direct audio output.
- 💻 Desktop broadcasting allows you to demonstrate any applications installed on your PC.
- 🎞️ File streaming allows you to open a video file from a disk directly in your browser and send it to TV.
Image quality in Chrome is often higher than with standard Miracast, thanks to efficient stream encoding. However, the load on the computer's processor increases, as it is responsible for encoding the video stream in real time.
Third-party streaming apps
Built-in operating system tools don't always work perfectly, especially if Wi-Fi adapter drivers are outdated or conflicting. In such cases, specialized programs come to the rescue. One of the most reliable solutions is the app LetsView or AirServer, which are installed both on the PC and on the Dexp TV (if it is possible to install APK).
If installing apps on a TV is not possible, you can use server programs on your PC that emulate media storage. For example, Plex or KodiYou install the server part on your computer, specify the movie folders, and install the client application from the app store on your Dexp TV.
This approach transforms your TV into a fully-fledged media center with a beautiful interface, movie posters, and descriptions. It requires initial setup, but provides a better user experience in the long run.
⚠️ Important: When using third-party software, make sure the Windows Firewall allows access for this application. Often, it's the firewall's blocking of ports that prevents the connection.
To configure your firewall, go to Control Panel, find "Windows Defender Firewall," and select "Allow an app." Find your streaming program in the list and make sure the checkboxes for both private and public networks are selected.
Solving problems and delays
Even with proper setup, users may experience audio and video desynchronization or intermittent connection drops. Most often, this is due to airwave congestion or insufficient Wi-Fi signal strength. Input lag (input lag) is especially noticeable when trying to play games or work with text.
If the image is streaming but there is no sound, check your Windows sound settings. Right-click the speaker icon and select "Open Sound Settings." Under "Output," select your Dexp TV as the default device. Sometimes you may need to restart the Windows audio service.
services.mscFind the "Windows Audio" service in the list, right-click it, and select "Restart." This often resolves the issue of audio dropping out over a wireless connection.
It's also worth considering that transmitting 4K video over Wi-Fi requires a very high bandwidth. If your router is old or located far away, try reducing the output resolution on your computer to 1080p. This will significantly reduce bandwidth usage and eliminate image tearing.
Comparison of connection methods
The optimal connection method depends on your specific needs. If you need to share a presentation with colleagues, Miracast or Chrome will do. For watching downloaded movies, DLNA is better. And for low-latency gaming, wireless methods may not be suitable at all.
Let's look at the main differences in performance and convenience. Technology Miracast It's convenient because it's native to Windows, but it can be picky about drivers. DLNA Reliable for video, but doesn't stream desktop. Chrome Cast universal, but loads the processor.
The table below provides a comparison of the key characteristics of the methods:
| Method | Latency | Picture quality | Difficulty of setup |
|---|---|---|---|
| Miracast | Average | High | Low |
| DLNA | Low (for video) | Maximum | Average |
| Chrome Cast | High | Good | Low |
| HDMI (cable) | Minimum | No losses | Low |
In summary, connecting your computer to your Dexp TV via Wi-Fi is a modern and convenient standard. It eliminates unnecessary cables and provides flexibility in content management. By following the instructions above, you can set up image streaming in just a few minutes.
Why doesn't my Dexp TV see my computer in the list of devices?
Most often, the problem is that the devices are connected to different networks (for example, one to a guest network and the other to the main network) or network discovery is disabled in Windows. Also, check if your antivirus software is blocking the connection.
Is it possible to connect a computer to Dexp without a router?
Yes, if your Wi-Fi adapter supports Mobile Hotspot mode. You can share Wi-Fi from your laptop and connect your TV to this network, but the speed may be limited.
How to remove audio delay when watching videos?
Try using a player on your TV (via DLNA) instead of screencasting. If this isn't possible, some PC players (such as VLC) have an audio latency compensation setting.
Does the streaming work if the computer is sleeping?
No, the computer must be awake to transmit data. However, you can enable Wake-on-LAN in the power settings to wake the PC over the network, but the broadcast itself requires a running OS.
