Hi, I have a very similar issue.
Recently bought a Lenovo with Windows 11 Pro with USB Type C and HDMI.
The USB Type C connection from Laptop to Monitor is working well but the HDMI is not.
The Monitor is: HP M34d WQHD Curved Monitor
The laptop is: ThinkBook 14 G2 ITL
11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz 2.42 GHz
Sistema operativo de 64 bits, procesador basado en x64
Windows 11 Pro, Version 22H2
Windows Feature Experience Pack 1000.22662.1000.0
The HP official support website does not have drivers for he Windows 11 version for this specific HP Monitor. https://support.hp.com/us-en/drivers/selfservice/hp-m34d-wqhd-curved-monitor/2100695735
