Macbook Pro not detecting monitors

[trevorash]

Hey everyone I'm not able to get a quad monitor setup to work on my Macbook Pro so hoping someone can help point me in the right direction.

I have four HP p244 23.8" monitors and I'm connecting them to my Macbook Pro (https://support.apple.com/kb/SP775?viewlocale=en_US&locale=en_US) using two HP Thunderbolt dock 230 W G2, (https://www.hp.com/us-en/shop/pdp/hp-thunderbolt-dock-g2-with-combo-cable) with two monitors plugged into each one, and then each dock plugged separately into the USB-C ports on my Macbook Pro.

The issue I'm having is that all four monitors turn on, but each of the two monitors that plug into the separate HP Thunderbolt docks are showing the same display, ie. they're mirrored.

I've installed Display Link Manager and getting the same thing.

The HP docking stations you are using do NOT have DisplayLink technology inside of them, so DisplayLink will not be able to assist you.

The HP docking stations have a DisplayPort MST hub inside of them which drives the external displays. macOS does NOT support DisplayPort MST, which is why the image content is being mirrored on the displays.

Ahh okay that's the problem. Thanks for the response.

So what would be my solution if the HP docks won't work? Is there a specific dock I can purchase that will allow me to use the Display Link software to connect 4 external monitors to my Macbook?

Yep I found that after I posted my question. Didn't realize how it worked with their technology being inside of hardware devices. Should have done some looking first. Thanks for the point in the right direction, appreciate it!
