How to connect a DEXP TV to a computer via Wi-Fi: step-by-step instructions

Modern multimedia capabilities allow you to transform a regular TV into a full-fledged entertainment center, streaming content directly from a personal computer. DEXP People often wonder how to get rid of unnecessary cables and set up wireless image transmission. This not only frees the workspace from cable clutter but also allows you to display photos, videos, and presentations on a large screen without being tied to the physical location of a laptop or PC.

There are several proven ways to accomplish this task, each with its own characteristics and equipment requirements. Wireless connection This can be done via built-in Smart TV protocols, dedicated apps, or external adapters if your TV model doesn't support Smart functions. The optimal method depends on the year of manufacture of your device. DEXP, the computer operating system and the required signal transmission quality.

In this article, we'll take a detailed look at all available synchronization options, from built-in Windows features to using DLNA servers. You'll learn how to set up a lag-free display for gaming or work, as well as how to organize your media library for watching high-definition movies. The key to a successful connection is that both devices are on the same local Wi-Fi network, which is often overlooked during initial setup.

Checking compatibility and preparing equipment

Before you begin setup, you need to make sure your equipment is technically ready for wireless data transmission. Most modern TVs DEXP Smart TVs already have built-in Wi-Fi and support Miracast or DLNA. If you have an older model without Smart TV features, you'll need to purchase an external adapter, such as a Google Chromecast, Apple TV, or a Miracast dongle that plugs into the HDMI port.

Your computer or laptop must also meet the minimum requirements: a wireless network adapter and an operating system of at least Windows 8.1 (for native Miracast support) or third-party software installed. Make sure your network card drivers are updated to the latest version, as this directly impacts connection stability and video stream speed.

It is important to check the current firmware version of your TV. DEXPManufacturers regularly release updates that may add support for new codecs or improve wireless module performance. Go to the settings menu and find the software update section to rule out software-level compatibility issues.

⚠️ Note: If your router operates in the 2.4 GHz band and is congested with neighboring networks, the quality of your wireless video stream may be significantly impacted. For comfortable streaming of Full HD or 4K content, we strongly recommend using a dual-band router with 5 GHz support.

Make sure both devices—the TV and the computer—are connected to the same Wi-Fi network. A common mistake is connecting one device to a guest network or a different router frequency band, making them "invisible" to each other on the local network.

Using Miracast Technology in Windows 10 and 11

The easiest and fastest way to broadcast images from your computer screen to your TV DEXP — Use the built-in Windows feature called "Projection" (previously known as Wi-Fi Direct or Miracast). This method allows you to clone your screen or extend your desktop without installing additional software, as long as both devices support the standard.

To get started, press the key combination Win + K on your computer's keyboard. The "Connect" sidebar will appear on the right, where the system will begin searching for available wireless displays. On the TV DEXP At this time, you may need to launch the Wireless Display, Screen Share, or Miracast app through the Smart Hub menu to put the device into connection standby mode.

Once your TV's name appears in the list on your computer, click it. A connection permission pop-up may appear on the TV screen; confirm this using your remote control. Once the connection is established, the image from your PC monitor will appear on the big screen.

If you want to change the screen mode, press Win + P and select the appropriate option: “Duplicate” (the image on both screens is the same), “Extend” (the TV becomes a second monitor) or “Second screen only” (the PC monitor goes dark, only the TV works).

  • 📺 Duplicate - ideal for showing presentations or photos to friends.
  • 💻 The extension is convenient for working when a video is running on the TV while you continue working on your PC.
  • 🎮 Second screen only - allows you to use your TV as your primary monitor for games or movies, saving your PC's resources.

⚠️ Note: When using Miracast for fast-paced games, you may notice a slight delay (input lag) between your keyboard input and the display on the screen. This method is not suitable for shooters and competitive games; it's better to use an HDMI cable.

Connection stability directly depends on the strength of your Wi-Fi router's signal. If you notice image artifacts or audio desync, try moving closer to the router or reducing the transmitted image resolution in Windows display settings.

Setting up a DLNA server to play media files

If your goal isn't to mirror your desktop, but to watch movies, listen to music, or view photos stored on your computer's hard drive, then DLNA technology is ideal. It allows your TV DEXP view computer folders as network resources and play content using your own processor.

In Windows, this feature is called "Media Streaming." To enable it, open "Settings" (via the Start menu or Win + I), go to the "Network & Internet" section, then select "Status" and find the "Media Streaming Settings" link. In the window that opens, click "Turn on media streaming."

After activating the function, find your TV in the list of devices DEXP and make sure it's allowed to access content. By default, Windows may block unknown devices, so you'll need to check the "Allowed" box next to your TV.

Now, launch the "Media" app on your TV (or "Photos," "Videos," or "Music," depending on your DEXP interface model). Select your computer's name from the list of sources. You'll see the shared folder structure. Navigate to the desired folder and launch the file.

Parameter Description Recommended value
Video formats Supported containers MKV, MP4, AVI, TS
Codecs Compression algorithms H.264, H.265 (HEVC), MPEG-4
Audio tracks Sound formats AC3, AAC, MP3, DTS
Subtitles Text formats SRT, ASS, SSA (external)

It's important to understand that when using DLNA, the TV decodes the video itself. If the file has a high bitrate or a rare codec, the TV hardware DEXP doesn't understand that playback may start with a delay or not start at all, even if the movie plays without problems on the PC.

What should I do if my TV can't see DLNA folders?

Make sure your computer's network settings are set to "Private Network" and not "Public." Windows blocks device discovery and file sharing on public networks by default. You can switch the profile in "Network & Internet" -> "Status" -> "Connection Properties."

Broadcasting via Google Chrome browser

Another universal method that works on almost any computer is to use a browser. Google ChromeThis method is especially useful if standard Windows tools don't find the TV or don't work correctly. Chromecast is built into the browser itself and allows you to cast individual tabs or the entire desktop.

To get started, open the Chrome browser on your computer. Click the three dots in the upper-right corner of the menu and select "Cast." If this option isn't in the main menu, it may be hidden under "Save and Share" or "More Tools."

In the window that opens, select a broadcast source. You can broadcast:

  • 🌐 Tab - transfers the contents of only one open browser tab.
  • 🖥️ Desktop - broadcasts the entire computer screen with sound.
  • 📁 File - allows you to select a video file from the disk for playback.

After selecting the source, click on the name of your TV DEXP in the list of available devices. If you have an Android TV set-top box or an embedded Android system, streaming will begin almost instantly. Picture quality in this mode is usually high, but also depends on Wi-Fi speed.

The advantage of this method is its cross-platform compatibility: it works equally well on Windows, macOS, and Linux. Furthermore, Chrome makes it easy to stream video from websites that block direct output to DLNA servers.

Connecting via third-party applications

Built-in operating system tools aren't always ideal, so there are specialized programs that expand connection functionality. These often offer more flexible buffering settings, support for more formats, and an improved control interface.

One of the popular programs is Home Media Server or PlexThese applications create a powerful media server on your PC. After installing the server on your computer and the corresponding application on your TV, DEXP (if available in the TV app store), you get access to a library of movies with covers, descriptions, and the ability to continue watching from where you left off.

For users who want to control their computer from the couch, remote control apps like Unified Remote or TeamViewerThey allow you to control the cursor, launch programs, and type text using a smartphone screen or TV interface, which can be convenient for navigating files.

⚠️ Please note: TV operating system interfaces (Android TV, Saphi, and DEXP custom shells) are subject to update. Menu item locations and app names may differ from those described in the instructions. Always consult the latest user manual for your specific model.

Some apps require a paid subscription to unlock high-definition streaming (4K HDR). Please review the terms and conditions carefully before installing to avoid unexpected charges.

Solution and connection optimization

Even with proper setup, users may encounter issues such as choppy video, no sound, or an inability to find the device. Most often, the cause lies in Windows Firewall or antivirus settings that block incoming connections to media servers.

Try temporarily disabling your antivirus or adding the server program (or DLNA system service) to the exceptions list. It's also worth checking if your router is set to AP Isolation mode, which prevents devices on the network from seeing each other.

If the image is transmitted, but the sound comes through the computer speakers, click on the speaker icon in the Windows tray, select the playback device and select your TV from the list DEXP or "Wireless Audio." This will switch the audio stream to external speakers.

To improve stability, it's recommended to statically assign IP addresses for your TV and computer in your router settings. This will prevent situations where, after a router reboot, the devices receive new addresses and become unable to see each other on the local network.

Final comparison of connection methods

The connection method you choose depends on your specific needs. If you need to show a presentation, use Miracast. DLNA is a better choice for watching downloaded movies in high quality. And for fast streaming of online videos, use Chrome Cast.

Keep in mind that wireless transmission always introduces a slight delay and depends on air traffic. For mission-critical applications where every millisecond counts, or for viewing content at maximum bitrate without compression, a trusty HDMI cable remains unrivaled in terms of reliability.

Technology is developing, and modern televisions DEXP are becoming smarter, supporting new coding and wireless standards. Keep your devices updated regularly to take advantage of all the latest improvements.

Why doesn't my DEXP TV see my computer in the list of devices?

Check if network discoverability is enabled in Windows. Make sure both devices are connected to the same network (not a guest network). Try rebooting the router and both devices.

Can you play games on TV via Wi-Fi?

Technically, it's possible, but input lag will make it uncomfortable for fast-paced games like shooters and racing games. For turn-based strategy or card games, the lag isn't a big deal.

How to improve picture quality over a wireless connection?

Use a router that supports 5 GHz, position it closer to the TV, and disable background downloads on other devices. Reduce the signal resolution in your display settings if you experience choppy internet connection.

Is internet required for DLNA to work?

No, DLNA (local file streaming) doesn't require internet access. Both devices need to be connected to the same router, even if the router doesn't have access to the external network.
