Need help for dual screen and dock station

[Bacasable]

Hello everyone,

My company give me an old MacBook Pro 2017 i5 2,3GHz 128Go, dang this is laggy pc !

But, I would like to use my HP dock G3 to connect my dual screen from my desk.

HP Elite usb-c dock G3

So when I plug the thunderbolt cable, there is only one screen working, that's odd. On my windows laptop I plug it and everything work seamless.


Could you help me please and explain me how do you do with your dual or even triple screen desk ?

Thanks

What model of 2017 MBP? Might be 15" or 13" with 2 Thunderbolt or 13" with 4 Thunderbolt. Most likely the 13" with 2 Thunderbolt (from the CPU speed).

What resolution screens? The 13" models support two external screens up to 4096x2304.

I notice the spec for your doc only mentions Windows, not Mac. And it is a USB-C dock. You might do better with a Thunderbolt dock - but make sure it is supported for 2 screens on your MBP.

To start diagnosing:
Do both of your screens work when connected one at a time via the dock?
Do both of your screens work when connected one at a time to the MBP Thunderbolt ports?
Do two displays work together if each is connected to one of your Thunderbolt ports (using suitable cables)?

Thanks for answering me,

My MacBook Pro is a 13" with 2 usb-c slot, I guess 2 thunderbolt, and my dock is a thunderbolt connected.

My two desk screens are FHD and wide HD, not very demanding in ressources.

i will inspect further later, thanks

Thanks for confirming the model.

My point about the dock. USB-C is a physical port specification. It can be used for Thunderbolt, DisplayPort and various USB 3.x protocols. Your dock is connected to a Thunderbolt 3 capable (40 Gb/s) on your Mac, but the dock is only USB. The spec of the dock is not clear, but I assume not more than 10 Gb/s (maybe less).

Start without the dock and see how you go connecting one or both directly to Thunderbolt ports.

My guess is, you’ll have to connect one display through the dock (which will also provide power to the Mac). The other display will have to connect directly. Some docks use “MST” (Multi-Stream Transport) to support multiple displays; which isn’t compatible with Macs.
