WD19TB with Macbook Air M3 or Macbook Pro M3 Pro

Hi flarezt,

have you tried to connect one of the monitors via usb c thunderbolt?

• One monitor must be first connected using the DisplayPort port (DP, HDMI, USB-C port) and the other monitor must be connected using the Thunderbolt port on the dock.
• The displays are mirrored if both the monitors are connected using the DisplayPort on the dock (that is, DP and HDMI (or) DP and DP (or) DP and USB-C).

If your monitors not support usb c, you can use a usb to DisplayPort or HDMI Adapter I think.

Hi YanniSani,

thank you for your reply. The thing is that I don't have a Macbook and I am just wondering if someone from this community tested these laptops with wd19tb.

Oh, I read that wrong. I actually have an M3 chip MacBook Pro and had ordered a USB-C to DP cable yesterday so that I could use my MacBook with two extended displays. I ordered the following cable:

I have just connected it full of expectation but unfortunately it doesn't work.

I tried the following combinations:

DP (2) and USB-C (8): No display on one of the external monitors. Which one depends on the order in which I plugged them in. Also not work with closed lid.
DP (2) and USB-C (4): Same display (mirrored) on both external monitors with the lid open or closed.

On Windows and Ubuntu, both combinations work.

I really want to make this work. Do you @flarezt or anyone else have an idea to make this work? I have just ordered a second USB-C to DP cable to try the combination USB-C (4) and USB-C (8). This is the combination used in the picture in the Dell article. The cable will be delivered on Monday. I will get back to you then.

Thank you for sharing your experience. I hope that you will find a solution. 

I have been searching for a while and found this article https://support.apple.com/en-us/101571 which says that MacBook Pro with M3 chip supports only 1 display. Perhaps you can get two external displays working if you close the lid of your laptop. Alternatively, as far as I heard utilization of DisplayLink dock might help but again it has to be tested. 

The second USB-C to DP cable has now arrived and unfortunately, as expected, it does not work with the MacBook Pro M3 to extend the display to all screens. Not even when the lid is closed. If I connect both monitors to the laptop without a docking station, I don't get a display on one of the monitors either. Apparently, only one extended display is really supported on the MacBook Pro with M3, which I find pretty weak, since even my old MacBook from 2015 worked with two extended monitors (via two Thunderbolt 2 ports). But that's not the issue here.

But DisplayLink is a good keyword @flarezt. I have now ordered the Dell Universal Dock D6000 which uses DisplayLink technology. I will let you know if it works. 

Hi YanniSani, I am glad to hear that it works! Thank you very much for the update!
