Connecting an Asus laptop to a Samsung TV via Wi-Fi: 5 wirelessly working methods

Wireless screen mirroring from a laptop to a big-screen TV has become a standard feature of modern devices, but in practice, users often encounter compatibility issues, connection drops, or poor picture quality. If you have a laptop Asus (regardless of the series - VivoBook, ZenBook, ROG or TUF) and TV Samsung with support Smart TVThis guide will help you choose the optimal Wi-Fi connection method and avoid common mistakes.

Unlike a wired connection, HDMI, wireless methods require taking into account several factors at once: versions Wi-Fi (5 GHz vs 2.4 GHz), protocol support (Miracast, DLNA, AirPlay), the laptop's processor power, and even the distance between devices. For example, streaming games from Asus ROG Strix on Samsung QLED through Steam Link will require different settings than watching a movie with Asus VivoBook on Samsung Crystal UHD through DLNA.

In this article we will discuss:

  • 🔌 Direct connection via Miracast (built-in Windows feature) - when it works and when it's best not to use it.
  • 📺 DLNA and Screen Mirroring through standard applications Samsung — pros and cons for different types of content.
  • 🎮 Gaming solutions: Steam Link, Moonlight And Parsec for gamers with laptops Asus ROG/TUF.
  • ⚡ Alternative programs (ApowerMirror, LetsView) - when they help out, and when they slow you down.
  • ⚙️ Setting up a router For minimal latency—why video can lag even at 5 GHz.

1. Check device compatibility: Does your Asus and Samsung support Wi-Fi broadcasting?

Before attempting to connect devices, make sure they are technically capable for wireless broadcasting. Samsung And Asus There are some nuances:

Device Miracast requirements DLNA requirements Steam Link Requirements
Asus laptop (any model) Windows 8.1/10/11, Wi-Fi Direct support, adapter driver with Miracast Any OS, presence of a media player (for example, VLC) NVIDIA/AMD/Intel graphics card (for Moonlight - only NVIDIA), Steam installed
Samsung TV (2016–2026) Smart TV on Tizen, Screen Mirroring support (in the "Sources" menu) Any model with Smart TV, application SmartThings or Samsung TV Plus 2018+ models (for Steam Link), or any with third-party apps installed
Router Support 5 GHz (recommended), WPA2/WPA3 Any, but preferably 5 GHz for Full HD 5 GHz is a must, low ping (<30 ms)

How to check Miracast support on an Asus laptop:

  1. Click Win + R, enter dxdiag, click Enter.
  2. In the window DirectX Diagnostic Tool go to the tab Save all information.
  3. Find the line Miracast: Available. If it is written Not supported - your adapter is not suitable.
⚠️ Attention: On laptops Asus with adapters Realtek (For example, RTL8821CE) Miracast often works unstable. If in dxdiag It says "Available", but the connection is interrupted - update the driver from official Asus website (not through Device Manager!).

How to check Screen Mirroring support on your Samsung TV:

  • 📺 Press on the remote control Source (Source).
  • 🔍 There should be an item in the list Screen Mirroring or On-screen display.
  • ⚙️ On 2020+ models (e.g. Q60T, AU8000) this item may be hidden in Settings → General → External devices.
What to do if there is no Screen Mirroring option?

On Samsung TVs from 2015 and later (J, K series), Screen Mirroring may not be available. In this case, the following options remain:

- Use DLNA to stream media files (but not the screen).

- Connect an external Miracast adapter (for example, Microsoft Wireless Display Adapter) to the TV HDMI port.

- Update TV firmware via the menu Settings → Support → Software Update (Sometimes Samsung adds support in new versions).

2. Method 1: Miracast (Screen Mirroring) – direct connection without a router

This is the most universal method for casting the entire laptop screen to a TV, but it requires both devices to support Wi-Fi DirectThe main advantage is No router needed: the laptop and TV are connected directly, which reduces delays. However, this method has limitations:

  • ⚠️ Maximum resolution - usually 1920×1080 at 30 Hz (on some models Asus ROG With Intel Wi-Fi 6 possibly 60 Hz).
  • 🎮 Input lag — ~50–100 ms, which is critical for games, but normal for movies.
  • 🔋 Battery consumption — the laptop will discharge faster due to the active Wi-Fi module.

Step-by-step instructions:

  1. On TV Samsung:
    • Open Sources (button Source on the remote control).
    • Select Screen Mirroring (or On-screen display).

    • 🔄 Restart both devices — sometimes resetting network settings helps.
    • 🔧 Update your Wi-Fi adapter driver on a laptop (download from the website) Asus for your model).
    • 📶 Check your Wi-Fi range: Miracast works better on 5 GHz, but some TVs Samsung support only 2.4 GHz.
