How to Display Your Computer on a TV via Wi-Fi: A Complete Guide (2026)

Broadcast your computer screen to a large TV via Wi-Fi — it's a convenient way to share photos with family, watch a movie in high definition, or even play games wirelessly. But many people encounter problems: the image lags, the sound drops out, and the TV simply doesn't recognize the PC. In this article, we'll explore all the current wireless screen sharing methods, from built-in features Windows And macOS to specialized applications.

We tested each method on TVs. Samsung QLED 2023, LG OLED C2 And Sony Bravia X90K, as well as on laptops with Windows 11, macOS Ventura And Ubuntu 22.04Particular attention was paid to hidden router settings that affect broadcast stability—without adjusting them, even Miracast may experience delays.

If you need to show a presentation or video urgently, start with the section about DLNA — this is the most universal method, which works even on older devices. It's best suited for gamers. Steam Link or Moonlight, and to the owners of equipment Apple — AirPlayBut first, check if your TV supports the selected protocol.

1. Preparing a Wi-Fi network: why is broadcasting slow?

Before you set up your broadcast, make sure that your Wi-Fi network Meets the minimum requirements. Most issues with latency and artifacts arise due to:

• 📶 Weak signal — if the signal level is below 70%, the picture will “disintegrate” into squares.
• 🔄 Congested channel - neighboring networks on the same channel create interference.
• 🖥️ Outdated Wi-Fi standard — for Full HD needed 802.11ac (Wi-Fi 5) or newer.
• 🛡️ Firewall or antivirus - They can block streaming.

Check your current router settings:

1. Open your router's control panel (usually at 192.168.1.1 or 192.168.0.1).
2. Go to the section Wireless (Wi-Fi) → Settings.
3. Install:
   • Opening hours: 802.11ac/n/ax (not lower 802.11n)
   • Channel width: 40 MHz or 80 MHz (for 5 GHz)
   • Channel: Choose the least loaded one (use apps like Wi-Fi Analyzer)

⚠️ Attention: If your router does not support 5 GHz, broadcast in higher resolution 720p will be unstable. In this case, connect the TV to the router with a cable and leave the computer on Wi-Fi.

For maximum stability we recommend using Mesh system (For example, TP-Link Deco or ASUS ZenWiFi) or a router with support Wi-Fi 6 (AX3000 and higher). If you have a regular router, place it closer to the TV or use repeater with support MU-MIMO.

2. Method 1: Miracast (built-in Windows function)

Miracast — is a wireless screen sharing standard supported by most modern TVs and laptops. It works without the internet, directly between devices (peer-to-peer), which reduces delays.

To check if your computer supports Miracast:

1. Click Win + R, enter dxdiag and press Enter.
2. In the window DirectX Diagnostic Tool go to the tab Save all information.
3. Open the saved file and find the line Miracast: Available.

If there is support, follow the instructions:

• 🖥️ On your computer: click Win + K (or Win + P → Connect to a wireless display).
• 📺 On your TV: Turn on the function Screen Mirroring (at Samsung — Smart View, at LG — Screen Share).
• 🔗 Select your TV from the list of available devices.

Brand TV	Miracast function name	Path to the menu
Samsung	Smart View	Settings → General → Smart View
LG	Screen Share	Settings → Network → Screen Share
Sony Bravia	Miracast	Settings → Network → Miracast
Xiaomi	Wireless Display	Settings → Connection and Sharing → Wireless Display

⚠️ Attention: On some TVs Samsung 2018-2019 Miracast only works when connected to the same Wi-Fi network as the computer, despite the stated support peer-to-peerCheck this in your model's manual.

If the image is not transmitted:

• Update your graphics card drivers (especially for Intel UHD Graphics).
• Disable the power saving mode of your Wi-Fi adapter in Device Manager.
• Try connecting to your TV via 5 GHz, if it supports this range.

3. Method 2: DLNA (for videos, photos, and music)

DLNA (Digital Living Network Alliance) is a protocol for transferring media files over a local network. Unlike Miracast, it doesn't mirror the screen, but streams specific files (movies, photos, music). Suitable for:

• 🎬 Watch movies in high definition (up to 4K HDR).
• 📷 Photo album demonstrations.
• 🎵 Play music through TV speakers.

How to set up DLNA on Windows:

1. Turn on the function on your TV:
   • U Samsung: Settings → General → External Devices → DLNA Device.
   • U LG: Settings → Network → DLNA.
4. On your computer, open Settings → Network & Internet → Sharing options.
5. Turn on Network discovery And File and Printer Sharing.
6. Install a server program, for example:
   • Plex Media Server (for organizing a media library).
   • Kodi (with UPnP/DLNA support).
   • Windows Media Player (built-in, but limited).

For macOS will do Plex or InfuseOnce configured, the TV will see your computer as a media server—all you have to do is select the file to play.

⚠️ Attention: DLNA doesn't support live screen mirroring (for example, for games or desktops). For this, use Miracast or specialized software.

If the TV does not see the computer:

• Make sure both devices are on the same subnet (eg. 192.168.1.x).
• Turn it off AP Isolation in the router settings (this blocks data exchange between devices on the network).
• Make sure the service is running on your computer. SSDP Discovery And UPnP Device Host.

4. Method 3: Steam Link (for gamers)

2. Click on the icon Screen control in the menu bar (or Control Center → Screen Mirroring).
3. Select your TV from the list.
4. If necessary, enter the PIN code that appears on the TV screen.

For Windows installation will be required iTunes and third-party utilities like 5KPlayer or ApowerMirrorHowever, the broadcast quality will be worse than with macOS.

⚠️ Attention: By default, AirPlay transmits audio along with the picture. If the audio is delayed, disable it in your TV settings. Lipsync (lip sync).

6. Method 5: Broadcasting applications (Moonlight, ApowerMirror, TeamViewer)

If built-in features don't work, use specialized programs. We've tested three of the most stable solutions:

Setting up Moonlight (best choice for gamers):

1. Install on your computer NVIDIA GeForce Experience and turn it on GameStream in the settings.

   • Mode: Game (for minimal delays).

Suitable for office tasks TeamViewer or AnyDesk, but keep in mind that these programs are not optimized for video streaming - expect lag and artifacts.

7. Troubleshooting: Why the broadcast isn't working

If the image is not transmitted or is slow, check the following:

• 🔌 Wi-Fi adapter power supply: On laptops, disable power saving for Wi-Fi in Device Manager → Network Adapters → Properties → Power Management.
• 🔒 Firewall: Add exceptions for broadcast programs (eg. miracastview.exe for Windows).
• 📡 Wi-Fi channel: If you use 2.4 GHz, switch to 5 GHz or channel 6 (less busy).
• 🖥️ Screen resolution: Reduce the resolution on your PC to 1920×1080, if the broadcast is choppy.

Common mistakes and their solutions:

| Error | Reason | Solution |

|--------|---------|---------|

| "The device does not support Miracast." | Old video card or driver | Update driver or use DLNA |

| "No sound during broadcast" | Windows Sound Settings | Set the device to "Default" NVIDIA Audio or AMD High Definition Audio |

| "The screen is flickering" | Wi-Fi channel interference | Change the channel to 5 GHz or use cable |

| "Latency 500+ ms" | Weak router or network congestion | Disconnect other devices from Wi-Fi or use a mesh system |

If all else fails, try an alternative streaming method. For example, instead of Miracast, use Steam Link or HDMI adapter (For example, Microsoft Wireless Display Adapter).
