How to Connect a TV to a PC via Wi-Fi on Windows 10: A Complete Guide

Connecting your TV to your computer wirelessly via Wi-Fi opens up a ton of possibilities: from watching movies on the big screen to playing PC games on Smart TVHowever, many users encounter compatibility issues, image lag, or setup difficulties. In this article, we'll cover all current connection methods—from built-in functions Windows 10 to specialized applications, and we will also provide recommendations for optimizing broadcast quality.

It is important to understand that the connection method depends on your TV model and operating system version. Modern Smart TV (For example, Samsung QLED 2022+, LG OLED C-series or Sony Bravia XR) support protocols Miracast And DLNA out of the box, while budget models may require additional hardware or software. If your TV was manufactured before 2018, check its specifications on the manufacturer's website—some features may have been added later via firmware updates.

Before you begin setting up, make sure both devices are connected to the same network. Wi-Fi networksUsing different bands (2.4 GHz and 5 GHz) can cause device detection issues. We also recommend disabling the VPN on your PC, as some broadcast protocols block access through virtual networks.

1. Connect via Miracast (wireless display)

Miracast — is a wireless image transmission standard built into Windows 10 (starting with version 1803). It allows you to mirror or extend your PC screen to your TV wirelessly, but requires both sides to support the technology. Smart TV After 2019, compatible with Miracast, but on some models Samsung This function can be called Screen Mirroring or Smart View.

To check support on PC, click Win + R, enter dxdiag and find the line Miracast in the section System Information. If it is indicated there Available, your computer is ready to connect. On your TV, activate signal reception mode—this is usually done through the menu. Settings → Connections → Screen Mirroring (the exact path depends on the model).

• 🔧 On PC: Open Settings → System → Display and select Connect to a wireless display.
• 📺 On TV: Turn on the mode Screen Mirroring (on LG — Miracast, on Sony — Wireless Display).
• 🔄 Synchronization: Select your TV's name from the list of available devices on your PC. Confirm the connection on both devices.

If your TV does not appear in the list, try the following:

1. Reboot the router and both devices.
2. Update your video card drivers on your PC (especially important for Intel UHD Graphics And AMD Radeon).
3. Disable Windows Firewall temporarily - it may be blocking the connection.

⚠️ Attention: On some TVs Samsung (series Q60B Miracast only works when connected to a 5 GHz network. If your router doesn't support this range, use the alternative methods in the following sections.

2. Using DLNA to stream media files

DLNA (Digital Living Network Alliance) is a protocol for exchanging multimedia between devices on a local network. Unlike Miracast, it doesn't mirror the screen, but allows you to stream individual files (video, music, photos) from your PC to your TV. This method is ideal for watching movies or listening to music without straining your computer's processor.

To set up DLNA on Windows 10 follow these steps:

1. Open Control Panel → Network and Internet → Network and Sharing Center.
2. Select Change advanced sharing options and turn it on Sharing media streams.
3. Check the box Allow devices to play my files and save the settings.

On your TV, launch a media player app (e.g. SmartShare on LG, Media Player on Sony or Photos & Videos on Samsung). In the list of sources, select your PC—it should appear under its network name. Now you can view files from folders Video, Music And Images.

If your TV doesn't see your PC on the DLNA network, check:

• 🔌 Firewall settings: Add port exceptions 1900 (UDP) And 2869 (TCP).
• 📂 Folder Permissions: Open Properties folders, go to the tab Access and set up General access for the user All.
• 🔄 Network profile: in Settings → Network & Internet → Status → Change connection properties select Private network.

3. Steam Link for games and media

If you plan to play PC games on your TV, the best solution is an app Steam LinkIt allows you to stream not only games from your library Steam, but also any other applications (including a browser or media player) with minimal latency. The main requirement is a powerful PC (from Intel Core i5 or AMD Ryzen 5) and a stable Wi-Fi network (5 GHz recommended).

Setup instructions:

1. Install Steam on your PC and log in to your account.
2. Download the app Steam Link on TV (available in Google Play Store For Android TV or App Store For Apple TV).
3. Connect a gamepad (for example, Xbox Controller or DualSense) to the TV via Bluetooth.
4. Launch Steam Link on TV, select your PC from the list and confirm the connection.

To optimize streaming quality:

• 🎮 In the settings Steam Link select Customizable resolution and install 1920×1080 at 60 Hz.
• 📶 Switch to a Wi-Fi channel with minimal traffic (use apps like Wi-Fi Analyzer).
• 🔌 Connect your PC to the router via Ethernet - this will reduce ping and eliminate artifacts.

⚠️ Attention: When using Steam Link on TVs Samsung (2020 models and later) may experience a sound issue. Solution: In the app settings, select Outputting audio via HDMI and restart the broadcast.

4. Alternative apps for wireless connection

If built-in tools Windows 10 If they aren't suitable, you can use third-party programs. Below is an overview of the most reliable solutions:

To connect via ApowerMirror or LetsView:

1. Download and install the program on your PC from the official website.
2. Launch the app on your TV (if available in the store) or use the built-in browser to access the web version (e.g. letsview.com/web).
3. On your PC, enter the PIN displayed on your TV screen.

Important: When using third-party screen sharing apps, avoid entering personal information (login/password for accounts) on the mirrored screen—some apps may transmit this information unencrypted.

5. Troubleshooting connection issues

If your TV is not detected or the connection keeps dropping, try these tips:

• 🔄 Rebooting devices: Turn off the power of the router, PC and TV for 30 seconds, then turn them on again.
• 📡 Changing the Wi-Fi channel: In the router settings (192.168.1.1 or 192.168.0.1) select a channel with minimal interference (for example, 6 or 11 for 2.4 GHz).
• 🔧 Firmware update: Check for updates for your TV in the menu Settings → Support → Software Update.
• 🛡️ Security settings: Temporarily disabling the antivirus (for example, Kaspersky or Avast) may help if it blocks network protocols.

If the image slows down or artifacts are observed:

• Reduce the broadcast resolution to 1280×720 in the Miracast settings or application.
• Close background programs on your PC that consume internet (for example, torrents or cloud synchronization).
• Use an Ethernet cable to connect your PC to the router - this will reduce the load on your Wi-Fi.

Why can't the TV see the PC on the network?

The most common cause is a mismatch in network profiles. Windows 10 may assign the connection type "Public Network" by default, which prevents devices from being discovered. To fix this, go to Settings → Network & Internet → Status → Change connection properties and select "Private Network." Also, check if AP Isolation mode is enabled on your router—it prevents devices on the same network from communicating.

6. Optimizing broadcast quality

To comfortably watch movies or play games over Wi-Fi, you need to ensure a stable connection speed of at least 25 Mbps for Full HD and 50 Mbps for 4K. Here's how to achieve it:

• 📶 5 GHz band: If your router supports dual-band Wi-Fi, connect to the 5 GHz network—it's less crowded and provides greater throughput.
• 📍 Router location: Place it in an open area, at least 1 meter above the floor. Avoid proximity to microwaves, cordless phones, and other sources of interference.
• 🔄 QoS (Quality of Service): In the router settings (192.168.1.1) enable QoS and set maximum priority for the MAC address of the TV or PC.

For games through Steam Link or Miracast:

• In the game's graphics settings, reduce the render resolution to 90% from native.
• Disable vertical sync (V-Sync) to reduce input lag.
• Use a wired gamepad instead of Bluetooth - this will reduce latency by 20-30 ms.

⚠️ Attention: On TVs Xiaomi Mi TV (models before 2021) When streaming via Miracast, you may experience choppy sound. Solution: In your PC's sound settings (Control Panel → Sound) set the format 16 bit, 44100 Hz (CD quality).
