Hello, I bought the following product: https://www.club-3d.com/en/detail/2580/

I own a 2021 Macbook Pro 14″ with the Apple Silicon chip. When connecting my two screens to the dock (one via HDMI, one via DisplayPort, only the screen via HDMI is recognised by the Macbook. Once I connect the HDMI screen via another mobile dock, both are recognised.

Any idea which settings do use to connect both screens to my Club3d gen2 dock and both showing up at my Macbook?

Thanks a lot in advance!

ah, and I forgot to mention that I tried all possible combinations with both via HDMI, one HDMI and other DisplayPort, and vice versa – without success.

The issue lies with the M1 processor in your Macbook. M1 only supports 1 additional display over the ALT-mode function of USB-C. Your other dock might have a DisplayLink chipset in it this is why it then recognize 2 displays.

TL;DR M1 does not support MST, you need a dock like the CSV-1595

I thought that the M1 pro would support MST, but might be wrong .

The other dock is the following one: https://amzn.eu/d/eZ5KGrX

Do you also know another Club 3D one besides the CSV-1595 I could use for my purpose but does have a DisplayPort as well?

CSV-1566 could be an option. It uses 1 ALT-mode HDMI and 2 DiplayLink Displayports. So this should get what you want.

Hey, so I have this docking station and I have one display though the HDMI and one through the display port and they only mirror each other. Any insight?

Did you install the drivers?

What about M1 Pro or M1 Max or M1 Ultra? club-3d docs seem to imply (by omission) that only Intel macOS doesn’t support MST.

As far as I know macOS for M-series Macs also doesn’t support MST but I have not tested this personally.

Intel and M-Series Macs can support DisplayLink but that has nothing to do with MST. I don’t think DisplayLink supports MST.

PowerPC and 68K Macs don’t support DisplayPort so of course those won’t support MST.

As far as I know, M1 pro and max still do not support MST, however the multiple thunderbolt ports do each support 1 display. This is what I understood.

M-series Macs (Pro, Max, Ultra) support two displays per Thunderbolt port using Thunderbolt docks/hubs/displays up to the max total number of displays supported.

While the M1 Max only has 3 Thunderbolt ports, you can connect four displays to Thunderbolt if two are connected to the same Thunderbolt port (using a dock or hub or chaining in the case of Thunderbolt displays with two Thunderbolt ports).

M1 and M2 only supports one display from Thunderbolt ports but they do have a second DisplayPort connection to allow dual tiled displays such as the LG UltraFine 5K or Dell UP2715K to work at full resolution.

For M1 Max, you can connect 3 LG UltraFine 5K to Thunderbolt ports and an HDMI display, plus the internal display makes 8 DisplayPort connections total (HDMI uses a DisplayPort adapter; 3 of the DisplayPort connections are for the second tile of the LG UltraFine 5K displays and can’t be used for separate displays).
