Hello, the Archer TX50E alone does not guarantee Miracast support. Miracast requires support from both the Wi-Fi adapter and the graphics driver/GPU.

Check support by running:

netsh wlan show drivers

Look for "Wireless Display Supported: Yes" (or similar). If it says No, update both:

The TP-Link Wi-Fi driver
Your Intel/AMD/NVIDIA graphics driver

Also make sure Screen Mirroring/Wireless Display is enabled on the Samsung TV.

The "Miracast preferred band" setting only chooses 2.4 GHz vs 5 GHz; it won't enable Miracast if your PC doesn't support it.

Hi, @donnabryant

Thanks for reply.

When i try connnect my laptop to TV, it's works. TV support miracast.

You wrote: "The "Miracast preferred band" setting only chooses 2.4 GHz vs 5 GHz; it won't enable Miracast if your PC doesn't support it." There's a setting like this in the Wi-Fi card's settings, which means the card supports Miracast.

command "netsh wlan show drivers" output Graphical driver does not support Wireless Display, Driver Wi-Fi: yes.

I will try update graphics driver.
