Connecting a computer screen to a Samsung TV via Wi-Fi: all the working methods

Wirelessly cast your computer screen to your TV Samsung Wi-Fi saves space, eliminates cables, and allows for flexible use of a large screen for work, gaming, or viewing content. However, not everyone knows that there are several technologies for this—from built-in functions Smart View And Miracast to specialized applications like Steam Link or MoonlightEach of them has its own nuances: some require compatible hardware, others a stable 5 GHz channel, and in some cases you'll have to put up with image lag.

In this article, we will look at all the current connection methods, including step-by-step instructions for Windows 10/11 And macOSWe'll also look at common problems, from no sound to disconnected connections. We'll pay special attention to televisions. Samsung at the base Tizen OS (models from 2016 and newer), as their firmware supports most wireless protocols out of the box. If your PC or laptop is not equipped with a module Wi-Fi 5/6, we will tell you how to bypass this limitation with minimal costs.

1. Preparing the TV and computer: what to check before connecting

Before attempting to connect devices, make sure they meet the minimum requirements. Three parameters are critical for wireless screen sharing:

• 📺 TV model: must support Miracast (wireless image transmission standard). That's all Samsung Smart TV on Tizen starting from 2016 (series KU/MU/NU/RU/TU/AU and newer). You can check the menu Settings → Support → About TV.
• 💻 Computer: on Windows 10/11 the driver must be installed Wireless Display (checked in Device Manager → Network Adapters). For macOS third-party software will be required (for example, AirParrot).
• 📶 Router: For minimal latency, a dual-band router with support is recommended. 5 GHz (standard 802.11ac or newer). At frequency 2.4 GHz lags and artifacts are possible.

Also check that both devices are connected to one Wi-Fi networkIf your TV uses an Ethernet cable and your PC uses Wi-Fi (or vice versa), streaming won't work. To test your TV's connection speed, go to Settings → General → Network Settings → Network Status and make sure that the ping to the router does not exceed 20 ms.

⚠️ Attention: If your TV Samsung released before 2016 (series JU/HU and older), built-in support Miracast may be missing. In this case, use external adapters (for example, Microsoft Wireless Display Adapter) or applications like Steam Link.

2. Method 1: Built-in Smart View (Miracast) function

The easiest method is to use technology Miracast, integrated into Windows And Samsung TizenIt allows you to duplicate or extend your screen without additional software, but requires compatible hardware. Instructions for Windows 10/11:

1. Open on your TV Settings → General → External Devices → Miracast Device (or Screen Mirroring in the English-language firmware).
2. On PC, click Win + K (or open Settings → System → Display → Connect to a wireless display).
3. Select your TV model from the list of available devices. SamsungConfirm the connection on both devices.

If your TV doesn't appear in the list, update the network adapter drivers on your PC via device Manager or the manufacturer's website (for laptops) Dell/HP/Lenovo proprietary drivers are often required Intel Wireless). Also check that the mode is disabled in the router settings. AP Isolation (client isolation), which blocks communication between devices on a local network.

TV and PC on the same Wi-Fi network (5 GHz)

Screen Mirroring is enabled on the TV.

Wi-Fi adapter drivers have been updated on the PC.

VPN and firewalls are disabled (temporarily)

Wi-Fi power saving mode on your PC is disabled-->

3. Method 2: Samsung Smart View app (for Windows/macOS)

Official app Samsung Smart View It not only allows you to mirror your screen, but also control your TV from your computer. It supports models Samsung since 2012, but wireless screen sharing still requires Miracast or DLNADownload the utility from official website and follow the instructions:

1. Install and run Smart View on your PC. The app will automatically find the TV on your local network.
2. Choose yours Samsung TV in the list of devices and click Connect.
3. In the application menu, go to the tab Screen and select the mode Duplicate or Expand.

When using Smart View there may be a delay of up to 100–150 ms, which is noticeable when watching videos or playing games. To reduce lag:

• 🔌 Connect your TV to your router with an Ethernet cable (if possible).
• 📡 Switch to the channel 5 GHz in the Wi-Fi settings.
• 🖥️ In the settings Smart View Reduce the broadcast resolution to 1280×720.

⚠️ Attention: Application Samsung Smart View does not support audio transmission via Bluetooth simultaneously with screen sharing. For sound, use an HDMI cable or a separate one. Bluetooth adapter.

4. Method 3: Steam Link for games and media

If you need to stream games from your PC to your TV with minimal latency, the best option is Steam LinkThis app is from Valve optimized for video streaming and supports resolutions up to 4K@60Hz with a stable connection. Conditions:

• 🎮 Installed on PC Steam (even if the games are not from this platform).
• 📦 The app is installed on the TV Steam Link (available in Samsung App Store for models from 2018).
• 🌐 Wi-Fi speed is not lower 25 Mbps (For 1080p@60Hz).

Setup instructions:

1. Install Steam Link to TV via Apps → Search → Steam Link.
2. On your PC, open Steam, go to Settings → Remote Play and turn on the option Enable streaming.
3. Launch Steam Link on the TV, select your PC from the list and connect. You can use Bluetooth gamepad or mouse/keyboard.

Important: To reduce lag in games, activate it in the settings Steam Link "Performance Priority" mode and disable image post-processing. If the game supports DLSS or FSR, enable upscaling - this will reduce the load on the network.

5. Method 4: Alternative applications (Moonlight, Parsec, AirParrot)

If built-in methods aren't suitable, consider third-party solutions. They often offer better performance or additional features (such as audio streaming over Bluetooth or support HDR). Let's compare popular options:

For setup Moonlight:

1. Install Sunshine on PC (GitHub).
2. Install on your TV Moonlight through Sideload (if not in Samsung Store).
3. Add your PC to the list of devices in Moonlight and connect.

6. Typical problems and their solutions

Even with proper setup, errors can still occur. Let's look at the most common ones:

• 🔴 The TV does not appear in the list of devices:
  • Check that the TV is turned on. Screen Mirroring (Settings → General → External devices).
  • Update your Wi-Fi adapter drivers on your PC (especially if you are using Realtek).
  • Reboot your router - sometimes DHCP doesn't assign IP addresses correctly.
• 🔊 No sound during broadcast:
  • IN Windows check that in Sound parameters TV is selected as the output device.
  • For Miracast The sound is transmitted over the same channel as the video - if the image lags, the sound will be interrupted.
  • Use a separate one Bluetooth transmitter for sound (for example, Creative BT-W5).
• 🖥️ Lag in movement:
  • Switch to 5 GHz or use Ethernet for TV.
  • Reduce the broadcast resolution to 1280×720.
  • Close background applications on your PC that consume network bandwidth (torrents, cloud synchronization).

⚠️ Attention: If after connecting through Miracast The message "Not supported format" appears on the TV, try changing the screen resolution on your PC to standard (1920×1080 or 1366×768) and turn it off HDR.

Why does the broadcast cut off after 5-10 minutes?

This is a common issue when using routers with energy-saving settings. In the router control panel (usually at 192.168.1.1) disable the options:

• Wi-Fi Power Save (power saving mode)
• Beamforming (sometimes conflicts with Miracast)
• Band Steering (automatic switching between 2.4/5 GHz)

Also check that the sleep mode for the Wi-Fi adapter is not activated on your PC. Device Manager → Adapter Properties → Power Management.

7. Connection optimization: how to reduce lag and improve quality

Stream quality depends not only on the equipment but also on the network settings. Here are some key recommendations:

• 📡 Allocate 5 GHz band: In the router settings, create a separate network for 5 GHz and connect only your PC and TV to it. This will reduce interference from other devices.
• 🔧 Configure QoS: Turn on Quality of Service on the router and set the maximum priority for traffic between the IP addresses of the PC and the TV.
• 🖼️ Reduce the resolution: In most applications (except Steam Link) enough 1280×720 for comfortable viewing.
• 🔌 Use Powerline adapters: If Wi-Fi is unstable, transmit the signal through electrical wiring (eg. TP-Link AV1000).

To test the stability of the connection, use the command in Windows Terminal:

ping -t [TV_IP_address]

If the ping exceeds 50 ms or there is packet loss, the problem is in the network - check the router or cables.
