HP U27 4K W03D6 not connecting

[Luc782]

hi,

my HP wireless monitor is no longer connecting to my HP laptop (didn't have to use it for a long period of time...)

it  says  "connecting" but ends up not connecting and on the PC it says "connection could not be established".

i tried diverse solutions proposed on this site such as reset the PC, install the monitor's driver, restart monitor,  delete the monitor in Bluetooth & Devices... but none has worked.

please help

thanks,

Thanks for the suggestion, but I found the solution on the web : in fact it was due to Windows firewall blocking the "Wireless display" application...

Best regards,
