How to Stream Your PC Screen to Your TV via Wi-Fi: A Complete Guide

Wirelessly streaming images from your computer to a large TV screen opens up new possibilities for working, gaming, and viewing content. However, not everyone knows that for a stable streaming experience Wi-Fi connection quality Plays a key role—even a powerful router can experience lag if configured incorrectly. In this article, we'll cover all current wireless streaming methods, from standard protocols to specialized apps, and explain how to avoid common issues such as video stuttering and connection drops.

The peculiarity of modern TVs is that they support several signal reception technologies at once: from universal Miracast to proprietary solutions like Apple AirPlay or Google Cast. But the choice of method depends not only on the TV model, but also on operating system on a PC (Windows 10/11, macOS, Linux), as well as your needs—whether you need screen mirroring or just media transfer. We've tested all options on devices from different brands and compiled checklists for quick setup.

1. Network preparation: why Wi-Fi can slow down broadcasting

Before setting up a broadcast, make sure your network meets the minimum requirements. To transmit video in the following resolution: Full HD (1080p) a connection speed of at least is required 15–20 Mbps, and for 4K — from 50 Mbps. It's not just speed that's important, but also signal stability: Even short-term packet losses result in artifacts on the screen.

Problems often arise due to:

• 📶 Overloaded Wi-Fi channel — if many devices (smartphones, smart speakers, cameras) are connected to the router, they “take away” the bandwidth.
• 🔄 Outdated standard — routers that support only 802.11n (Wi-Fi 4) can't handle 4K streaming.
• 🏠 Obstacles in the signal path - walls, furniture and even microwave ovens create interference.
• ⚡ Incorrect QoS settings - if the router does not prioritize traffic for broadcasting.

To check the current connection speed between your PC and TV, use the utility iPerf3 (Free for Windows/macOS/Linux). Run it on both devices in server and client mode if the speed is lower. 100 Mbps, it is worth reconfiguring the router or using 5 GHz band (it is less susceptible to interference, but has a smaller coverage area).

⚠️ Attention: If your TV only supports 2.4 GHz, and the router is operating in mixed mode, force it to turn off 5 GHz in the network settings on your PC - this will prevent automatic switching between bands, which can interrupt the broadcast.

2. Method 1: Miracast is a universal protocol for Windows

Miracast — is a wireless streaming standard built into Windows 8.1/10/11 and most modern TVs (since 2013). It allows you to mirror your PC screen to your TV without any additional software, but requires both devices to support the technology. You can check compatibility as follows:

• 🖥️ On PC: Click Win + K - If the "Connect" panel appears, your computer supports Miracast.
• 📺 On TV: Go to network settings and find the “Screen Mirroring”, “Wi-Fi Direct” or “Miracast” options (for Samsung this is "Smart View" LG — «Screen Share»).

Connection instructions:

1. On your TV, activate Miracast reception mode (usually in the Network or Screen menu).
2. On PC, click Win + K, select your TV from the list.
3. Confirm the connection on both devices (you may be asked to enter a PIN).

If your TV doesn't appear in the list, update your drivers. video cards And Wi-Fi adapter on a PC. To do this:

1. Open device Manager (Win + X → Device Manager).
2. Expand the "Video adapters" and "Network adapters" branches, update the drivers for each device (right-click → "Update driver").

Make sure your TV and PC are on the same Wi-Fi network|Disable VPN on your PC|Check for Windows updates|Restart your router-->

⚠️ Attention: On laptops with hybrid graphics (e.g. NVIDIA Optimus) Miracast may not work due to a driver conflict. In this case, temporarily disable the discrete graphics card in NVIDIA Control Panel → Manage 3D settings.

3. Method 2: DLNA/UPnP – streaming media files without screen mirroring

If you don't need to duplicate your entire desktop, but only transfer movies, music, or photos, the protocol is suitable DLNA (Digital Living Network Alliance). It works on the server-client principle: the PC acts as the content server, and the TV acts as the client that plays this content. The main advantage is no delays, since the video is not encoded in real time.

To set up DLNA on Windows:

1. Open Settings → Network & Internet → Sharing options.
2. Turn on network discovery And file sharing.
3. Install a server program, for example, Plex Media Server or Kodi (free versions support DLNA).
4. Add folders with media files to the program library.

On TV:

1. Go to the "Media Player", "DLNA" or "Multimedia" application (the name depends on the model).
2. Select your PC from the list of devices.
3. Find the file you need and start playback.

For macOS, the built-in function is suitable Media sharing (System Preferences → Sharing), but it doesn't support all video formats. An alternative is the program VLC with the DLNA server enabled.

4. Method 3: Steam Link – for gamers

If you want to play on the big screen without buying a console, Steam Link — the perfect solution. This app from Valve broadcasts games from PC to TV over a local network with minimal delays (from 30 ms with good Wi-Fi). The main condition is that the platform must be installed on the PC Steam, and the TV supports the installation of applications (or is connected Android TV/Fire Stick).

Step-by-step setup:

1. Install Steam Link on TV (available in Google Play for Android TV or App Store For Apple TV).
2. Launch Steam on your PC and log in to your account.
3. In Steam settings, enable Settings → Remote Access → Enable Streaming.
4. Open on TV Steam Link, select your PC and connect the gamepad (or use the on-screen controller).

To reduce latency:

• 🎮 Use a wired gamepad (Bluetooth adds ~20ms latency).
• 📡 Connect your PC to the router via cable, and leave the TV on Wi-Fi (or vice versa).
• ⚙️ In Steam Link settings, select Speed ​​priority instead of Quality Priority.

⚠️ Warning: When streaming games over Wi-Fi, avoid using 5 GHz channels above 100 - some routers automatically switch to DFS- channels that can be blocked by radar (this will lead to communication loss). Manually set channel 36, 40, 44, or 48.

How to play without a gamepad?

If you don't have a controller, you can enable Big Picture mode in Steam Link and control games using a virtual keyboard and mouse on your TV screen. To do this, select Controller Settings → Virtual ControllerKeep in mind that this method is only suitable for strategy or simulation games—it will be inconvenient for shooters.

5. Method 4: Google Cast (Chromecast) and Apple AirPlay

If you have a TV with Android TV or the device is connected Google Chromecast, you can use technology Google CastIt allows you to broadcast both individual browser tabs and the entire PC screen. It is relevant for macOS. AirPlay - he works with Apple TV and some TVs LG/Sony with AirPlay 2 support.

3. On your PC, enter the PIN code displayed on the TV screen.

7. Troubleshooting: Why the broadcast is slow or cuts out

Even with proper setup, glitches can still occur. Here are typical causes and solutions:

• 🐢 Video lag and stuttering:
  • Reduce the broadcast resolution in the settings (for example, from 4K to 1080p).
  • Disable background programs that consume traffic (torrents, cloud synchronization).
  • Turn on the mode Gaming QoS in the router settings (if any).
• 🔌 Constant connection breaks:
  • Switch from 5 GHz on 2.4 GHz (if the signal is weak).
  • Update your router firmware (check on the manufacturer's website).
  • Change the Wi-Fi channel manually (use Wi-Fi Analyzer to search for a free channel).
• 🖥️ The TV doesn't see the PC:
  • Reboot both devices and the router.
  • Disable Windows Firewall (Control Panel → Firewall → Turn off).
  • Check that the TV is in the "On" mode. Screen Mirroring.

If the problem persists, try alternative broadcast methodFor example, if Miracast doesn't work, use DLNA for media files or Steam Link for games.

⚠️ Note: On some TVs Samsung (2018–2020 models) Miracast support may disappear after a firmware update. In this case, resetting the network settings on the TV will help (Settings → Support → Network reset).

FAQ: Frequently Asked Questions

Is it possible to stream my PC screen to TV without Wi-Fi?

Yes, there are three alternative ways:

1. HDMI cable — the most stable solution without delays.
2. Wi-Fi Direct — direct connection of a PC to a TV without a router (not supported by all models).
3. USB-C/Thunderbolt → HDMI — for modern laptops with video output via USB-Type C.

For Wi-Fi Direct on Windows, click Win + K, then select the Connect to a wireless display option (if your TV supports this mode).

Why is the audio broadcast but not the video?

This is a problem with Miracast and occurs because:

• Outdated drivers video cards (update them through GeForce Experience or AMD Adrenalin).
• Incompatible codec (try changing the video format in the broadcast settings).
• Restrictions DRM (for example, when trying to stream Netflix).

Solution: Use DLNA to play files or check the settings Sound → Playback Devices on PC (TV must be selected as the output device).

How to stream from PC to TV if they are on different networks?

To do this you need:

1. Connect PC and TV to the same network via mobile hotspot (share Wi-Fi from your phone).
2. Use programs like TeamViewer or AnyDesk, which work via the Internet.
3. Tune VPN server on the router (for example, through OpenVPN) and connect both devices to it.

Please note that the delay when broadcasting over the Internet will be higher (from 300 ms).

What equipment is needed to stream 4K over Wi-Fi?

Minimum requirements:

• Router with support Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax).
• TV with HEVC codec (H.265) for 4K decoding.
• PC with video card no older than 2016 (for hardware encoding).
• Channel 5 GHz with width 80 MHz (configure in the router control panel).

For stable 4K/60fps streaming, it is recommended to use Mesh system (For example, TP-Link Deco or Google Nest Wi-Fi).

Is it possible to stream games from PC to TV without lag?

It is impossible to achieve zero latency, but it can be reduced to an acceptable level (~30–50 ms):
