Modern multimedia systems make it easy to stream content from your computer to the big screen, and Dexp TVs are no exception. Many users want to watch movies, photos, or presentations in high definition without the hassle of HDMI cables. Wireless connectivity solves this problem, transforming the living room into a full-fledged media center in minutes.
To implement this scheme, you will need a stable home network and support for the appropriate protocols on both devices. Miracast technology Built-in Windows features allow you to mirror your screen without purchasing additional hardware. Just make sure your router is working properly and its software is updated to the latest version.
In this article, we'll take a detailed look at all wireless connection methods, from standard operating system tools to specialized software. You'll learn how to set up Dexp Smart TV To receive a signal, which network parameters are critical, and what to do if your computer can't see your TV. Follow the instructions to enjoy content on the big screen.
Preparing equipment and a Wi-Fi network
The first and most important step is to ensure the correct network infrastructure. Both devices—the laptop and the Dexp smart TV—must be connected to the same Wi-Fi network. If you're using a dual-band router, ensure both devices are in the same frequency band, preferably 5 GHz, to ensure smooth high-definition video transmission.
Check if the wireless connection function is enabled on the TV itself. In the menu Dexp This is usually indicated by an active Wi-Fi icon in the corner of the screen. If the signal is weak, you may need to move the router closer to the receiver or use a Wi-Fi repeater to strengthen the signal in the viewing area.
⚠️ Caution: Using a guest Wi-Fi network or client isolation on your router will prevent devices from discovering each other. Make sure your router settings allow communication between connected clients.
It is also worth updating the TV firmware, as manufacturers often release patches that improve protocol stability. Miracast And DLNAGo to system settings and check for updates. This often resolves compatibility issues between old drivers on your laptop and new TV software.
Using the built-in Windows function (Projection)
Windows 10 and 11 operating systems have a built-in utility for wireless display. This method requires no additional software and is based on the Wi-Fi Direct standard. To get started, press the following key combination: Win + K on your laptop keyboard. A "Connect" panel will appear on the right.
Your TV should appear in the list of available devices. DexpIf it doesn't appear immediately, make sure the signal receiving app is running on your TV. Depending on your TV model and OS version, it may be called "Wireless Display," "Screen Mirroring," "Miracast," or "Screen Casting."
After selecting the TV, a connection confirmation message may appear on the screen. Use the remote control to grant access. The image from your laptop desktop will instantly appear on the TV. You can choose between screen mirroring or desktop extension, which is convenient for presentations.
☑️ Check before connection
Image quality directly depends on the wireless channel load. If you experience artifacts or cursor twitching, try closing background downloads on other devices. Miracast protocol sensitive to interference, so the proximity of the router plays an important role.
Stream media via DLNA
If your goal is not to duplicate the entire screen, but simply to play a movie or music stored on your hard drive, it is better to use the technology DLNAThis method requires less bandwidth and allows playback control using the TV remote. In Windows, this feature is available through "Streaming Media Settings."
To set up, find the desired video file on your computer, right-click it, and select "Transfer to device." Select your file from the list that appears. Dexp TVThe file will open in a standard player, and the image will be displayed on the TV. Controls (pause, volume) remain on the computer.
A more advanced option is to use a media server, such as the one built into Windows Media Player or third-party programs like Universal Media ServerThis allows you to create a content library accessible from the TV menu under "Media" or "Sources".
The advantage of DLNA is that the TV decodes the video itself, offloading the laptop's processor. You can turn off the laptop screen or minimize windows, and playback will continue uninterrupted. However, the file format must be supported by the TV's codecs.
Third-party streaming apps
Built-in tools don't always work perfectly, especially if your Wi-Fi adapter drivers are outdated. In such cases, third-party programs come to the rescue. One of the most popular and reliable is LetsView or ApowerMirrorThey require client installation on both the computer and the TV (via the Google Play app store on Android TV).
After installing the app on both devices, launch it. The program will automatically find the TV on the local network. Pairing often requires entering the code displayed on the TV screen into the program interface on the PC. This ensures a secure connection.
| Application | Connection type | Latency | 4K support |
|---|---|---|---|
| LetsView | Wi-Fi / USB | Low | Yes |
| ApowerMirror | Wi-Fi / USB | Average | Yes |
| Google Home | Wi-Fi (Chromecast) | Low | Depends on the content |
| Windows Projection | Miracast | Average | Yes |
Another option is to use the Google Chrome browser. If your TV has a built-in Chromecast or supports Cast technology, you can cast a browser tab. Click the three dots in the corner of the browser, select "Cast," and find your Dexp.
⚠️ Warning: When installing third-party software, carefully check the boxes in the installer. Often, along with a useful program, you'll be asked to install additional adware or change your browser's start page.
Troubleshooting device detection issues
A common problem is that the laptop simply doesn't see the TV in the list of available devices. First, check the network type in Windows. If the network is marked as "Public," the system is blocking detection. Go to Settings → Network and Internet → Wi-Fi, select your network and switch the profile to "Private".
It's also worth checking Windows services. Click Win + R, enter services.msc and find the "SSDP Discovery Service" service. It should be running and in automatic mode. Without it, DLNA protocols and media device discovery won't work.
What should I do if my Wi-Fi driver doesn't support Miracast?
If you see an error when trying to connect that your PC doesn't support Miracast, the issue may be with your wireless adapter driver. Try updating it through Device Manager or downloading the latest version from the laptop manufacturer's website. As a last resort, you can purchase an external USB Wi-Fi adapter with Wi-Fi Direct support.
Antivirus programs and firewalls can also block the connection. Try temporarily disabling the firewall and check if the TV appears in the list. If so, add an exception for the media service in the security settings.
Reduced latency and improved quality
A slight input lag is always present when using a wireless connection. While it's unnoticeable when watching movies, it can be annoying when gaming or working with text. To minimize lag, ensure your laptop is connected to a 5 GHz network, not a 2.4 GHz one.
Close all heavy applications on your laptop that use network or processor resources. Bitrate The video stream's bitrate changes dynamically depending on the system load. Freeing up resources will help make the image smoother.
If you're streaming for gaming, consider using an HDMI cable, as no Wi-Fi standard will provide the same responsiveness as a wired connection. However, for most multimedia tasks, the Dexp TV's Wi-Fi connection is sufficient.
