cast / display my Mi phone screen to my Dell windows 11; not that straight forward

 add wireless display to my Dell w11:

initially failed to install

updated windows serveral times

updates dell utils serveral times

then add wireless dosplay feature , very slow, but added

open wireless display on w11

then on Mi phone tap cast, but could not find my dell

google search again:

they may use a different protocol

in Mi phone, enable wireless certification

then follow

. Use the Correct Menu on Your Mi PhoneInstead of the standard "Cast" button in your quick panel (which looks for smart TVs/Chromecasts), you need to trigger the dedicated Miracast menu:Open Settings on your Mi phone.Go to Connection & sharing.Look for Wireless Display (not "Cast") and tap it.Toggle Wireless display to ON. Your PC name should now populate on this specific screen.

- basically tap wireless display, then Mi phone screen is casted to the Dell screen
