Trying to use mirror my PC to a TV on the same wifi using Windows 11's Miracast (Wireless Display - from PC to TV) on my G5 5000 PC (bought in Nov 2020) with a RTX2070 GPU card.  It cannot find the TV when I do the Win-K command.   I had even downloaded the "Wireless Display" drivers from Microsoft (which is really for device -> PC).

My MSI laptop and a XPS 8950 desktop work just fine.

I check my DxDiag and it says "Miracast: Available, No HDCP".  But HDCP is not mandatory for casting.  I had also updated all my drivers for Display/WLan/Killer Wifi.

Any suggestion?  Thx in advance.
