Connecting a Samsung TV to a Computer via Wi-Fi as a Monitor: A Complete Guide

Using TV Samsung As a wireless computer monitor, it's a convenient solution for presentations, watching movies, or expanding your workspace without the hassle of wires. However, not everyone knows that standard protocols like Miracast or DLNA Wi-Fi connections don't always provide stable image transmission from a PC to a TV. In this article, we'll explore working connection methods, their limitations, and ways to minimize latency, which is critical for gaming or graphics work.

The main problem is that most TVs Samsung (except for models with Wi-Fi Direct or support AirPlay 2) don't support direct connection to a PC as a mirrored screen using standard Windows tools. However, there are workarounds, ranging from proprietary apps to third-party utilities. We've tested all the current methods and compiled them in this guide, taking into account the nuances of different Windows versions and TV firmware.

Which Samsung TVs support wireless PC connectivity?

Not all models Samsung Smart TV They can function as a monitor via Wi-Fi. This capability depends on the year of manufacture, series, and firmware version. Here are the key criteria:

  • 📺 Series 2019 and newer (QLED, Neo QLED, The Frame, Serif) - supported Wi-Fi Direct And AirPlay 2, making it easy to connect to Mac and Windows 11.
  • 🖥️ 2016–2018 models (MU, NU, RU series) - require the use of an application Samsung DeX or third-party utilities like SpaceDesk.
  • ⚠️ Older models (2015 and earlier) - wireless connection as a monitor is impossible without additional equipment (for example, Google Chromecast or Miracast adapter).
  • 🔄 Tizen 5.5 and above — is required for stable operation AirPlay And Miracast.

To check your firmware version, go to Settings → Support → About TVIf your model does not support the required protocols, consider alternatives such as Steam Link (for game streaming) or Plex (for media files).

Computer and Wi-Fi network requirements

For a stable connection to your TV Samsung To connect a PC to a monitor via Wi-Fi, several technical requirements must be met:

Component Minimum requirements Recommended parameters
operating system Windows 10 (version 1809+) Windows 11 (22H2+) with updated Wi-Fi drivers
Wi-Fi adapter Support Wi-Fi 4 (802.11n) Wi-Fi 5 (802.11ac) or Wi-Fi 6 (for minimal delays)
Network frequency 2.4 GHz 5 GHz (less interference, higher throughput)
Internet speed From 10 Mbps From 50 Mbps (for Full HD without lags)

It is critical that both the computer and the TV are connected to one Wi-Fi networkIf you are using a dual-band router, make sure both devices are on the same subnet (for example, do not connect a PC to 5 GHz, and TV - to 2.4 GHz). To check, open the command prompt on your PC and enter:

ping [TV IP address]

If the ping exceeds 50 ms If packets are being lost, the problem may be with the router or interference. In this case, try:

  • 🔌 Reboot the router.
  • 📶 Switch to a less congested channel in your router settings.
  • 🔗 Use a wired connection for one of the devices (for example, a PC via Ethernet).

Method 1: Connecting via Miracast (for Windows 10/11)

Miracast — a wireless image transmission standard supported by most modern TVs Samsung (starting with the series MU2017). However, there are some nuances:

  1. Turn on the TV mode Screen mirroring:

    • Go to Settings → General → External Device → Screen Mirroring.
    • Select Miracast or Screen Mirroring (the name may differ).

    ⚠️ Attention: When connecting via Miracast the delay (latency) can reach 100–150 ms, making this method unsuitable for dynamic gaming or professional video editing. For such tasks, consider a wired connection. HDMI or specialized adapters like NVIDIA Shield.

    Method 2: Using Samsung DeX (for Samsung smartphone owners)

    If you have a smartphone Samsung Galaxy (S8 series and later, Note 8 and later), you can use the technology Samsung DeX For projecting a PC screen onto a TV. This method is suitable for office tasks, but not for gaming or high-definition video.

    • 📱 A smartphone is required Samsung with support DeX.
    • 🖥️ Your PC must have at least 4 GB of RAM And Windows 10+.
    • 🎮 Mouse/keyboard input lag can reach 200 ms.

    If built-in methods don't work, you can use third-party apps. They offer greater flexibility but may require more powerful hardware.

    1. SpaceDesk (for extending your desktop)

    SpaceDesk Allows you to use your TV as a second monitor with minimal latency. Suitable for office tasks and content viewing.

    • 💻 Install SpaceDesk Driver on PC.

    • 🖱️ Connect your gamepad or keyboard to your TV via Bluetooth.

    Important: A router with Wi-Fi 6 support and a minimum speed of 100 Mbps is recommended for Steam Link. Lower speeds may cause artifacts and lag.

    Troubleshooting connection and latency issues

    Even with proper setup, problems can still arise. Here are the most common ones and how to solve them:

    Problem Possible cause Solution
    The TV does not appear in the list of devices No support Miracast or Wi-Fi Direct Use SpaceDesk or Steam Link
    Severe lags in image transmission Slow Wi-Fi speed or interference Switch to 5 GHz, reduce the screen resolution on your PC
    There is no sound on the TV The wrong audio device is selected in Windows settings. In the Sound Control Panel, select the TV as the output device.
    The connection drops after a few minutes. Energy-saving settings for your Wi-Fi adapter Disable the option Allow the device to turn off to save power V Device Manager

    If the image is lagging, try:

    • 🔧 Reduce screen resolution on PC to 1280×720.
    • 📡 Move the router closer to the TV or use Mesh system.
    • 🔌 Connect your PC to the router via cable Ethernet, and leave the TV on Wi-Fi.
    Why is wireless connection not suitable for gaming?

    Even under ideal conditions, the delay in transmitting images via Wi-Fi is at least 30–50 ms, which is critical for shooters or racing games. For gaming, it's better to use:

    - Wired connection via HDMI 2.1 (delay 1–5 ms).

    - Specialized adapters like Razer Kishi + Moonlight for streaming from PC.

    - Consoles (PS5, Xbox Series X) with support ALLM (Auto Low Latency Mode).

    Alternative connection options

    If your wireless connection is not of satisfactory quality or stability, consider alternatives:

    • 🔌 Wired HDMI connection - zero latency support 4K@120HzRequires a cable length of up to 5 meters (for longer lengths, a signal amplifier is required).
    • 📡 Wi-Fi 6E adapters - For example, ASUS PCE-AX58BT (delay until 20 ms under ideal conditions).
    • 🖥️ Mini-PC on Android (For example, NVIDIA Shield TV Pro) — connects to a TV via HDMI and streams images from a PC over a local network with minimal lag.
    • 🌐 Cloud services (For example, Rainway or Parsec) - are suitable for games, but require internet speed from 50 Mbps.

    For office tasks or watching movies, a wireless Wi-Fi connection is a great option. But if you need minimal latency (for example, for AutoCAD or Photoshop), it is better to use HDMI or DisplayPort.
