However, many users encounter issues such as image lag, low resolution, or complete device incompatibility. In this article, we'll explore all the current methods. wireless connection — from built-in technologies Miracast And AirPlay to specialized applications like Steam Link or Moonlight.

We will pay special attention to hidden settings televisions Samsung, LG, Sony And Xiaomi, which often block wireless streaming by default. You'll learn how to bypass manufacturer restrictions, optimize input lag for gaming, and even customize 5 GHz-networks for stable transmission 4K-video. And at the end of the article - A unique compatibility chart for 2023–2026 devices, listing supported resolutions and refresh rates..

1. Built-in technologies: Miracast vs. AirPlay vs. Google Cast

Most modern TVs support at least one of three main wireless streaming technologies. The choice depends on your device ecosystem:

• 🖥️ Miracast — a universal standard for Windows And AndroidWorks on most TVs with Android TV, webOS (LG) and Tizen (Samsung). Doesn't require internet access, but is susceptible to network interference. 2.4 GHz.
• 🍎 AirPlay — exclusive to devices Apple (Mac, iPhone, iPad). Supported by TVs LG (since 2019), Samsung (since 2020) and Sony Bravia (since 2021). Allows you to broadcast 4K HDR, but with a delay of up to 100 ms.
• 📱 Google Cast (Chromecast) - works through applications (YouTube, Netflix) or browser ChromeSuitable for TV with Android TV or prefixes ChromecastCons: Doesn't support PC screen mirroring in games.

Important: Samsung artificially limits Miracast On 2022–2026 models in the CIS regions. To unlock this feature, you need to change the TV region to Europe via the service menu (instructions below).

⚠️ Please note: Manufacturers regularly update firmware, removing support for older protocols. For example, LG deleted in 2023 Miracast from webOS versions below 23. Before setting up, check the software version of your TV in the menu Settings → General → TV Info.

2. Step-by-step setup of Miracast on Windows 10/11

To connect via Miracast Your PC must support Wi-Fi DirectYou can check this via the command line:

netsh wlan show drivers

Look for the line Wireless display support: YesIf it is not there, update the adapter driver (for example, for Intel AX200 Download the latest version from the manufacturer's website).

Next, follow the instructions:

Update your Wi-Fi adapter driver

Enable Wi-Fi and Bluetooth on PC

Make sure your TV and PC are connected to the same network (not necessary for Miracast, but recommended)

Disable VPN and firewalls (they may block the stream)-->

1. Activate the reception mode on your TV:
   • Android TV: Settings → Devices → Wireless Display
   • LG webOS: Settings → Connection → Screen Mirroring (requires changing the region to Europe)
   • Samsung Tizen: Settings → General → External Device → Screen Mirroring

On PC, click Win + K and select your TV from the list. If the TV doesn't appear, restart both devices.

When connecting for the first time, you may be asked to enter a PIN code (displayed on the TV screen).

If the image is slow or choppy:

• 🔄 Switch to the network 5 GHz (if the router is dual-band).
• 📶 Reduce the distance between devices to 3–5 meters.
• 🔌 Connect your PC to the router via cable Ethernet, and leave the TV on Wi-Fi - this will reduce the load on the network.

3. AirPlay for Mac and iPhone: setup features

AirPlay — the most stable solution for equipment owners Apple, but with a number of nuances. Firstly, the TV must support AirPlay 2 (See the table below for the list of models). Secondly, input lag (input lag) reaches 80–120 ms, which is critical for games.

To connect:

1. Make sure your Mac/iPhone and TV are connected to the same Wi-Fi network (required!).
2. On Mac: open Control Center → Screen Mirroring and select TV.
3. On iPhone/iPad: swipe up to Control center, click Screen mirroring.
4. If the sound is not transmitted, check the settings. Sound output on Mac (TV must be selected).

To reduce latency:

• 🎮 Use in games Moonlight (see section 5) instead of AirPlay.
• 📺 On TV LG disable post-processing: Settings → Picture → Game Mode.
• 🔄 Switch to a router with support Wi-Fi 6 (For example, ASUS RT-AX88U).

⚠️ Warning: On TVs Samsung With Tizen AirPlay may be disabled after a firmware update on versions below 6.5. To restore the feature, reset the TV to factory settings (Settings → Support → Self-diagnosis → Reset) and update the software again.

4. Google Cast (Chromecast): Limitations and Workarounds

Google Cast It's convenient for streaming video from apps, but it's not suitable for mirroring your desktop. For example, you can only broadcast a browser tab. Chrome, but games or specialized software (like Photoshop) will be displayed with artifacts.

How to set up:

1. Install the extension Google Cast for browser Chrome (or use the built-in function in Edge).
2. Connect your TV and PC to the same Wi-Fi network.
3. In your browser, click Three dots → Broadcast and select TV.
4. To broadcast your entire screen, select Sources → Desktop.

Problems and solutions:

• 🖼️ Black screen during broadcast: Disable hardware acceleration in Chrome (Settings → System → Use hardware acceleration).
• 🔊 No sound: In the broadcast menu, select Sound → TV.
• 🐢 Lag at 4K: Reduce the resolution to 1080p in the broadcast settings.

How to stream games via Google Cast?

Technically this is possible, but with some caveats:

1. Run the game in windowed mode.

2. In Chrome broadcast only the game window (Sources → Window), not the entire desktop.

3. Use a router with Wi-Fi 6 and channel 160 MHz (For example, TP-Link Archer AX6000).

Even in this case, the latency will be 150-200 ms, which is unacceptable for shooters or fighting games. For gaming, it is better to use Moonlight or Steam Link (see next section).

5. Specialized applications for gamers: Steam Link, Moonlight, Parsec

If you need play on TV via Wi-Fi With minimal latency, standard protocols won't work. Instead, use:

• 🎮 Steam Link — optimized for games from the library Steam. Supports 4K@60Hz with a latency of 30–50 ms. Requires a PC with a graphics card. NVIDIA (from GTX 10xx) or AMD (from RX 5xx).
• 🌙 Moonlight - alternative NVIDIA GameStreamWorks only with video cards NVIDIA (from GTX 6xx). Latency is 20–40 ms when connecting to the network 5 GHz.
• 🖥️ Parsec — a universal tool for PC streaming. Supports 1440p@120Hz, but requires a stable internet connection (minimum 15 Mbps).

Setting up Moonlight (best option for gaming):

1. Install on PC NVIDIA GeForce Experience and turn it on GameStream in the settings.
2. Download Moonlight on TV (available in Google Play For Android TV or through SideQuest For LG/Samsung).
3. Connect to your PC via a local network (enter the computer's IP address manually if automatic search does not work).
4. In the settings Moonlight select:
   • Permission: 1080p or 4K (depending on the power of the router).
   • Bitrate: 20–30 Mbps For 1080p, 50+ Mbps For 4K.
   • Codec: HEVC (if TV supports it).

For Steam Link:

1. Install the application on your TV (available in official stores).
2. On your PC, open Steam → Settings → Remote Play → turn on Host.
3. Connect the gamepad to the TV (for example, Xbox Controller via Bluetooth).
4. In the settings Steam Link select Preset → Quality and set the bitrate to 15–25 Mbps.

6. Problems and solutions: why the TV won't connect

If your wireless connection is not working, please check the following:

How to change region on Samsung Tizen to unlock Miracast?

1. Turn off the TV and quickly press on the remote control Info → Menu → Mute → Power (sequence for 2020–2026 models).

2. In the service menu, select Option → Country and install Germany or United Kingdom.

3. Save the settings and restart the TV.

4. After changing the region, update the firmware via Settings → Support → Software Update.

⚠️ After changing the region, some local applications may disappear (for example, Kinopoisk or Amediateka).

If nothing helps, check:

• 🔧 Wi-Fi adapter drivers on PC (update via device Manager).
• 📡 Router settings: turn off WMM (in some cases it conflicts with Miracast).
• 🔒 Firewall: Disable it temporarily or add an exception for streaming apps.

7. Network optimization for stable broadcasting

Wireless streaming quality depends 80% on network settings. Here are the key parameters for optimization:

• 📶 Frequency and channel:
  • For 1080p@60Hz enough network 5 GHz with channel width 40 MHz.
  • For 4K@60Hz required 5 GHz with the channel 80 MHz or 160 MHz (the router must support Wi-Fi 6).
  • Avoid channels DFS (50–144 in the range 5 GHz) - they can switch automatically when radars are detected.
• 🔄 QoS (Quality of Service): Set up traffic priority for broadcasting devices. For example, on routers ASUS this is done in Adaptive QoS → MAC Priority.
• 🛡️ Security: Use WPA3 instead of WPA2 - this reduces authentication delays.

Recommended router settings for broadcasting 4K:

Wireless network mode: 802.11ac/ax (Wi-Fi 5/6)
Channel: 36, 40, 44, or 48 (5 GHz, non-DFS)
Channel width: 80 MHz
MTU: 1500 (or 1472 if there are problems with packets)
DHCP: Enabled, IP range out of conflict with other devices

To check the network stability, use the utility Wireshark or mobile app WiFi AnalyzerOptimal indicators:

• 📊 Ping between PC and TV: less 10 ms.
• 📉 Packet loss: less 0.1%.
• 📈 Connection speed: not less 300 Mbps For 1080p And 800 Mbps For 4K.

⚠️ Attention: If your router does not support Wi-Fi 6, but you want to broadcast 4K@60Hz, consider the option with Powerline adapters (For example, TP-Link AV2000). They transmit the signal through the electrical wiring and provide stable 1 Gbps without interference.

FAQ: Frequently asked questions about connecting a TV as a monitor via Wi-Fi

Is it possible to connect a TV to a PC via Wi-Fi without a router?

Yes, if both devices support Wi-Fi Direct. For example, Miracast works without a router, creating a direct access point. However, for AirPlay or Google Cast a shared network is required.

For Wi-Fi Direct on Windows:

1. Open Settings → Network & Internet → Mobile Hotspot.
2. Enable the option Allow use of my internet connection.
3. On TV, connect to the created access point (the name will be DIRECT-xx-PCName).

Why does the image lag when connecting via Miracast, but the sound is fine?

This is a typical problem when the network is overloaded. 2.4 GHzA video stream requires 10-20 times more bandwidth than audio. Solutions:

• Switch to 5 GHz (even if the TV and PC are connected directly via Wi-Fi Direct, the frequency remains 2.4 GHz by default).
• Reduce the resolution to 720p in the settings Miracast (on Windows: Settings → System → Display → Resolution after connection).
• Disable background applications on your PC that consume network bandwidth (torrents, cloud synchronization).

If the problem persists, check the power saving settings of your Wi-Fi adapter: Device Manager disable the option Allow the computer to turn off this device to save power.
