It's impossible to imagine a modern home without a multitude of digital devices, and the most logical step is to connect them into a single network. Using wireless technologies allows you to free the living room from unnecessary cables while maintaining high signal quality. Connecting a computer to a TV Through your home Wi-Fi router, you can access a huge media library stored on your PC's hard drive directly from the big screen.
There are several basic methods for implementing such a connection, each with its own characteristics and areas of application. Some technologies are designed for simple image broadcasts desktop, while others allow you to set up a full-fledged media server for watching high-definition movies. The choice of a specific method depends directly on your TV model, computer operating system, and image quality requirements.
In this article, we'll take a detailed look at all available connection options, explore the nuances of setting up a router for stable operation, and answer frequently asked questions. You'll learn how to set up DLNA servers, use built-in Windows features, and use third-party software for the most convenient multimedia experience.
Wireless data transmission technologies: what to choose
Before setting up, it's important to understand the terminology, as electronics manufacturers often use different names for the same protocols. The main standard for transmitting multimedia content is DLNA (Digital Living Network Alliance). This technology allows devices on the same network to "see" each other and exchange files without complex authorization.
For screen mirroring (when the TV becomes a second monitor), protocols are more often used Miracast or technologies from Google and Apple. They work differently, transmitting a video stream in real time, which is ideal for presentations or games, but can be less stable when watching heavy movies due to video stream compression.
There is also technology Wi-Fi Direct, which allows you to connect devices directly, bypassing the router. However, in the context of our question, we are specifically considering a scenario where both devices are connected to the same local network via an access point. This provides a wider range and the ability to simultaneously access the internet from other devices.
It is important to understand that the data transfer speed depends on the bandwidth of your wireless routerIf your router operates in the 2.4 GHz band, there may be delays when transmitting 4K video, so for more demanding tasks, the 5 GHz band is preferable.
Equipment preparation and compatibility testing
The success of the operation depends on how well the infrastructure is prepared. The first and most important requirement is that both the computer and the TV must be connected to the same router. If you have a dual-band router, make sure both devices are on the same frequency, although modern routers are usually able to correctly route traffic between bands.
Check your TV model. Most modern Smart TVs (Samsung, LG, Sony, Philips) have built-in Wi-Fi modules and support the necessary protocols. Older models may require purchasing a separate Wi-Fi adapter or using a set-top box.
⚠️ Attention: Make sure "Client Isolation" is not enabled on your router. If it is enabled, devices on the Wi-Fi network will not be able to see each other, and connection will be impossible.
There are also computer requirements. Windows 10 and 11 support wireless displays natively, but Linux or macOS may require additional steps or third-party software. It's also worth updating your wireless adapter drivers to the latest version.
Setting up a DLNA server on a Windows computer
The most common way to view photos and videos from a PC on a TV is to create a media server. This feature is built-in by default in Windows operating systems and doesn't require any additional software. To get started, open the Start menu and search for Streaming media options.
In the window that opens, you will see a list of devices on your network. Click the button Enable media streamingThe system will prompt you to select a name for your media server; by default, it will be your computer's name. After confirming, Windows will automatically open the necessary ports in your firewall.
Now you need to specify which folders will be available for viewing. By default, the system offers standard libraries (Videos, Images, Music), but you can add any other directories. To do this:
- 📂 Open File Explorer and go to the movie folder.
- 🖱️ Right-click and select "Media Stream Options" from the menu.
- ✅ Make sure your TV is shown in the list of allowed devices.
- 💾 Add the required folders to Windows libraries if they are not there.
After these steps, your computer should appear on your TV in the list of signal sources (Input/Source) or in the "Media" section. The TV interface will allow you to select folders and launch files directly from your PC's hard drive.
☑️ Check DLNA settings
Screen mirroring via Wi-Fi
If your goal isn't just to play a movie, but to show a presentation, a game, or browser content, you'll need the screen mirroring feature. In Windows 10 and 11, this is implemented through a project. Wireless Display. Make sure Screen Mirroring, Smart View (Samsung), or Anyview Cast (Hisense) is enabled on your TV.
On your computer, press the key combination Win + KThe "Connection" panel will appear on the right, where the system will begin searching for available wireless displays. Find your TV's name in the list and click it. A connection permission request may appear on the TV screen, which you'll need to confirm with your remote.
Once paired successfully, the image from your PC monitor will appear on your TV. You can change the operating mode via the menu. Settings → System → DisplayThree modes are available:
- 🖥️ Duplicate: the same image on both screens.
- 📐 Expand: The TV becomes a second desktop.
- 📺 Second screen only: PC monitor goes dark, only TV works.
It's worth noting that a slight input lag may be experienced when using wireless screen mirroring. This isn't critical for watching videos, but for fast-paced shooters or competitive gaming, a wired HDMI connection is better.
Why is there no sound on the TV when dubbing?
If the sound remains on your computer speakers after connecting, click on the speaker icon in the system tray (near the clock), select the up arrow, and change the output device to the name of your TV or AV receiver.
Using third-party software
Windows' built-in tools don't always work perfectly, especially with TVs from different brands. In such cases, specialized programs come to the rescue. One of the most popular and functional is PlexIt turns your computer into a beautiful media center with covers, movie descriptions, and subtitles.
Another powerful tool is Serviio or Universal Media ServerThese programs allow you to stream files in formats that your TV doesn't understand out of the box, transcoding them on the fly. This is especially useful for older TV models that don't support modern codecs.
For users who want to broadcast a Chrome browser tab or the entire screen, the app is perfect Google Home (if you have a built-in or external Chromecast) or simply use the "Cast" feature in the Chrome browser. This allows you to display any internet content on the big screen with one click.
| Program | Type | Complexity | Best for |
|---|---|---|---|
| Windows Media | Systemic | Low | Quick launch of video/photo |
| Plex | Media server | Average | A beautiful library of films |
| Miracast | Protocol | Low | Duplicate your desktop |
| Chrome Cast | Browser | Low | Web content broadcasting |
The choice of software depends on your needs: if you just want to share photos with family, the built-in tools will suffice. If you want to create a home theater with a collection of thousands of movies, it's better to spend time setting up Plex.
Solution and speed optimization
Even with proper setup, problems can still occur. The most common ones are video stuttering or audio desync. This almost always indicates insufficient Wi-Fi bandwidth or interference.
Try moving your router closer to your TV or computer. Metal structures, mirrors, and microwaves can significantly degrade the signal. It's also worth checking to see if the channel is being occupied by other devices (for example, someone downloading torrents or playing online games).
⚠️ Attention: Smart TV interfaces and router settings are regularly updated by manufacturers. The layout of menu items may differ from that described in the instructions. Look for similar sections related to "Network," "Connection," or "Media."
If the problem persists, try lowering the video bitrate or streaming the file at a lower resolution. To diagnose your connection speed, you can use special apps on your TV that show your data reception speed in real time.
Frequently Asked Questions (FAQ)
Is it possible to connect a computer to a TV if the TV does not have Smart TV?
Yes, it's possible, but you'll need an additional device. You can buy a TV set-top box (such as an Android TV), Chromecast, or Apple TV, which connect to your old TV's HDMI port and handle the Wi-Fi signal.
Why can't my computer see my TV on the network?
Most often, the devices are connected to different networks (for example, one to a guest Wi-Fi network and the other to the main network) or network discovery is disabled on the computer. Check that the network profile is set to "Private" and not "Public."
Does connecting other devices affect picture quality?
Yes, the Wi-Fi channel is shared between all connected clients. If someone is actively using the internet (video calls, downloads), the video stream may experience buffering or reduced quality.
Is it safe to share computer folders via DLNA?
Within your home network, yes. However, if you're in a public place or don't trust everyone connected to your Wi-Fi, it's best not to share your entire drive, but only specific folders containing media files.
