Hi,

How exactly does it not work?

If you press [ Win key ] + [ k ] on the PC keyboard, does the window that pops up show it searching for nearby devices or does it say something about not supporting Miracast?

Hello, it is just cannot search any devices.

Does it not search at all or does it search, but not find any devices?

After you press [ Win key ] + [ k ] does the pop up window look like A (blue horizontal bar is moving) or like B?
 

  A                                                              B

Yes, it is searching, but cannot find any devices.
When I search from notebook, then it can find my this TV.
It looks like that issue only with this USB dongle, not sure how to check why it is cannot find maybe something needs to be configured manually for TP dongle

Can you please check the Wi-Fi band (i.e. 2.4 GHz or 5 GHz) and channel settings of the Wi-Fi Direct AP on your TV?

In case you happen to have an Archer T4U made for the EU regulations (letters "EU" printed on the serial number label), then it won't be able to see channels 149 and higher in the 5 GHz band and you would have to make sure your TV doesn't use these Wi-Fi channels.
