I reviewed your post and I understand that you are facing issues connecting the monitor to your Mac computer.
Don’t worry, I assure you I will try my best to get this sorted.
HP monitors are not supported in a Mac environment. However, newer Macs use graphics with VESA modes and can display to most HP LCD monitors. To do this, connect the monitor to the Mac while the Mac is off, and then turn on the MAC. The monitor should operate at 60Hz. The INF and software for the HP monitor are for Microsoft Windows and cannot be run in a standard MAC OS environment.
However, I recommend you connect the monitor to a Windows computer using the same cable and check if it helps.
Let me know how it goes and you have a great day!
