Default M2 MacBook Air (2022) & External Display Not Working

Hello all, I just received my My MacBook Air (2022) with macOS Monterey 12.5 installed.

My external display does not work while plugged into my intpw Thunderbolt 3 Dual Monitor Docking Station (model IF508).

This docking station uses a display port connection for an external monitor. The monitor is an ACER S271HL with an HDMI port. I used an HDMI to DisplayPort cable by WARRKY (DH1 Series).

I downloaded DisplayLink 1.7.1 and the external display still does not work.

Can anyone help me figure out what I've done wrong? I am not sure what more information to provide.

Thank you in advance!

I'm wondering if the issue might be that the monitor may not support a DisplayPort connection even with the correct cable (HDMI to DisplayPort)?

This kind of technical stuff is a bit new to me.

Presuming you are using this model docking station --> https://www.amazon.com/Thunderbolt-S.../dp/B09895P78B

A. That docking station does not have DisplayLink technology inside of it. As a result, DisplayLink will not be able to assist you.

B. The DisplayPort video output of the docking station you have appears to be a 'pure' DisplayPort video output. If that is the case, you will need to use an 'Active' DisplayPort to HDMI adapter in order to convert the DisplayPort video output to a HDMI video input.

Your description of the DisplayPort to HDMI video cable you are using suggests it is a 'Passive' cable, which will not work.
