1. Checking Miracast support on your laptop and TV

Miracast Wireless Screen Sharing is a wireless screen sharing standard used in Windows 10 for the "Connect to a Wireless Display" feature. If your laptop or TV doesn't support this technology, they won't be able to detect each other. Here's how to check compatibility:

On the laptop:

  1. Click Win + R, enter dxdiag and press Enter.
  2. In the DirectX Diagnostic Tool window, go to the tab Save all information.
  3. Open the saved file DxDiag.txt and find the line MiracastIf it is written next to it Available, with HDCP — there is support.

On TV:

  • 🔍 Go to network settings and find the item Screen Mirroring, Wi-Fi Direct or Miracast (the name depends on the model).
  • 📺 On Samsung it could be Smart View, on LGScreen Share, on SonyMiracast or Wireless Display.
  • ❌ If this option is not available, your TV does not support Miracast, and you will have to use alternative methods for broadcasting (we will discuss them below).
Which TVs definitely DO NOT support Miracast?

Older models before 2015 (e.g., Samsung E/F series, LG LA/LN series), as well as budget TVs without a Wi-Fi Direct module. Miracast may also be absent on some smart TVs with alternative operating systems (e.g., some Xiaomi models with PatchWall).

Brand TV Minimum series/year for Miracast Alternative technology
Samsung Series H (2014+) / Tizen OS Smart View (DLNA)
LG UB series (2015+) / webOS 2.0+ Screen Share (DLNA)
Sony W Series (2013+) / Android TV Google Cast
Xiaomi Mi TV 4 (2017+) / PatchWall Miracast (not on all models)
⚠️ Attention: On some laptops with Intel For processors prior to the 4th generation (2013), Miracast may not work even with a Wi-Fi adapter. Check the specifications for your model on the manufacturer's website.

2. Update Wi-Fi and video card drivers

Outdated or corrupted drivers are one of the most common reasons why a laptop can't detect a TV via Wi-Fi. This is especially true for devices with adapters. Intel, Realtek or Broadcom, where Miracast support is implemented at the driver level.
