Issues detecting all monitors with a D6000, MacBook Air M2

[MacTacos]

Hi,

I am having issues with my new Macbook M2,

Model: MacBook Air M2,
macOS: Monterey (12.5.1)
Dockstation: Dell D6000 (USB-C)
DisplayLink: 1.7.1

Only 2 out of 3 monitors are working.
Monitor 1: Dell U27D - Works (DP to DP)
Monitor 2: Dell U27D - Works (DP to DP)
Monitor 3: Samsung G7 - Not working (HDMI to HDMI)

But if i were to use and connect my old Macbook Pro with Big Sur 11.6.2 and DisplayLink 1.5.0 it works flawlessly with above monitor settings.

Same issue here,
I am from M1 Macbook Air with similar setup

Monitor 1: LG Ultrawide - (DP to DP)
Monitor 2: LG Ultrawide - (DP to DP)
Monitor 3: Dell monitor - (HDMI to HDMI)

now I switched to M2 Mabook Air

If any 2 of 3 monitors connected, they are working until 3rd monitor connected.

switching back to M1 makes all 3 monitors working

Hi VA

I am having the same issue using MacBook Pro M2 with 3 x Asus VA24E monitors

Monterey 12.6
DisplayLink: 1.7.1

Monitor 1: ASUS VA24E (DP to HDMI) works
Monitor 2: ASUS VA24E (DP to HDMI) works
Monitor 3: ASUS VA24E (HDMI to HDMI) does not work

However, HDMI to HDMI works if I unplug the DP ports on the Dell dock.
Same setup works with an Apple MBP M1 and Apple MBP Intel laptops.

I am having the same issue using MacBook Air M2 with 3 x LG 23MP65 monitors

Monterey 12.6
DisplayLink: 1.7.1

Monitor 1: LG 23MP65 (DP to HDMI) works
Monitor 2: LG 23MP65 (DP to HDMI) works
Monitor 3: LG 23MP65 (HDMI to HDMI) does not work

However, HDMI to HDMI works if I unplug the DP ports on the Dell dock.
3 external monitors and 1 build-in on the Dell laptop with Windows OS works fine.

I'm having the same issue.

2022 MacBook Pro M2 with Dell D6000.
macOS Monterey v12.6
DisplayLink Manager v1.8 (released yesterday, 10/24/2022)

Monitor 1: Dell U2417H via DisplayPort
Monitor 2: Dell U2417H via DisplayPort
Monitor 3: Dell U2417H via HDMI

When I have all three connected, only the DisplayPort connected monitors turn on. When I turn off a DP monitor (either #1 or #2), the HDMI monitor turns on (#3).

I was upgrading from my Dell D3100, which works perfectly with three monitors. Was looking for a one plug solution to charge and dock, rather than using dongles.

Hello,

The problem seems to be with Alt-mode technology.

The Dell D6000 relies on two USB graphics technologies to support up to three external displays.

DisplayLink and USB-C DisplayPort Alternate Mode, an optional USB-C port feature that requires connecting the docking station directly to a compatible host computer's USB-C port using the original USB-C cable provided with the docking station.

DP Alt-Mode is used with HDMI if the other two ports are occupied and DisplayLink is used with DisplayPorts if using 3 external monitors. If you use just two external monitors DisplayLink will handle them regardless of what ports they are connected to - this is why you see HDMI working if one monitor connected to DisplayPort is disconnected from the dock.

If three external monitors are connected DisplayLink will only handle the DisplayPorts and HDMI will not be seen by DisplayLink driver as it will use different technology than DisplayLink.

DP Alt-mode is not related to our technology. For it to work you have to have Dell D6000 connected via USB-C and your computer has to support DP Alt-Mode. If your computer does not support this technology - the HDMI port (when using all video ports), will not work.

If you are connected via USB-C and you are certain that the computer does support DP Alt-Mode then it is best to consult Dell directly.

My question is
Why it was working fine with M1 then not with M2?
With exact same setup, I was using all 3 monitors on my M1 then I upgraded with M2 which now working with only 2.
And i searched and there still is a similar product using DisplayLink then works with 3 monitors on M2 machines.

Hi,

Has there been a resolution to the following?
Its a common issue that after searching is related to your drivers.

The comment you made here confuses me as with no displaylink driver the HDMI works and display port does not

"If three external monitors are connected DisplayLink will only handle the DisplayPorts and HDMI will not be seen by DisplayLink driver as it will use different technology than DisplayLink"


M1 Macbook Pro works fine
Windows 11 laptop works fine

Dell won't answer these questions as they rely on you for the MAC software correct?

M2 Macbook Pro-HDMI to HDMI port not displaying?

Please advise?
Happy to pull logs for you to understand how this can be resolved
