  • Monitor 2 connected to Logi Dock through USB to Displaylink adapter**

To get dual screen support for MAC with Intel Core Processor, MAC Mini M1 and MACM1 Pro/Max/Ultra please use the following setup

• For Mac with Intel Core Processor: dual monitor can only be supported with the following set-up
  • Monitor 1 connected to Logi Dock through HDMI or DisplayPort

*We do not certify any specific third-party USB-C to HDMI Cables. However, we have tested various cables for that use case and experienced no issues. An example of one of the cables we tested is here.

**We do not certify any specific third-party USB to Displaylink adapter. However, we have tested various USB to Displaylink adapters for that use case and experienced no issues. We do recommend using a DisplayLink certified adapter, and DisplayLink Manager software will also be required which can be downloaded free here. Recommendation is to allow DisplayLink Manager to enable "launch automatically after login".

Note: if you do not follow these guidelines you will find the MAC will mirror rather than extend your screen across the monitors.

Can the displayport be daisy chained?

DisplayPort Multi-Stream Transport (MST)

Resolution	Max number of monitor
4K 60Hz	1
4K 30Hz	2
1080P 60Hz	4
720P 60Hz	6

If HDMI is connected + 2 DisplayPort monitors in Multi-Stream:

• 1st HDMI: 4K@60
• Display Port 1: 4K@30 or 2560x1080@60
• Display Port 2: 4K@30 or 2560x1080@60

There is a prerequisite that your monitors and computer support DP 1.2 or above, and use DisplayPort Cables​. If you unsure, please visit your computer or monitor manufacturer website.

This resolution compatibility has been tested with a limited number of monitors and computers, hence we cannot guarantee that every monitor and computer combination will work with the expected resolution above. For any additional questions, please contact your Logitech representative.

Monitor is set at 4K but does not look 4K during a video call

Check that your HDR setting is off, outside of active video streaming.

macOS with HDR mode selected, screen looks pixelated when NOT watching a movie.

When you do not watch an HDR movie, please untick HDR mode, as it may provide lower resolution.

Connecting an external monitor to a USB type C port

Only monitors connected through HDMI or DisplayPort are supported. If you have a USB type C monitor it is recommended that you use an adapter USB-C to HDMI or USB-C to DisplayPort.

For further support, or if your question is not answered here, please use the "Contact Us" button on the left-hand menu to connect with a ProSupport agent.

Connecting HDMI monitor to Logi Dock's DisplayPort or DisplayPort monitor to Logi Dock's HDMI port

We do not certify any specific third-party directional DisplayPort to HDMI Cables. However, we have tested various cables for that use case and experienced no issues. An example of one of the cables we tested is here.

 

Recommended HDMI to DP adapter types

Logi recommends 'active' DP to HDMI adapters or cables are used with the Dock when enabling the DP on Dock for use with an HDMI monitor. Please check the cable manufacturers description confirms the cable is 'active' not 'passive'

Logi Dock not detected with Mac OS Ventura 13.0

Mac OS Ventura (13.0) may have a dialog pop up “Allow accessory to connect” when Logi Dock is connected via Upstream port. If you “allow” it, then it will be detected as expected. However if you hit "Don't Allow" the following is observed: 

• Monitors continue to work.
• Logi Tune does not detect Logi Dock or any connected peripherals.
• None of the USB peripherals connected to Logi Dock work.

In order to resolve this issue, please go into Settings -> Privacy and Security and change the selection again from the list to get system dialog “allow accessory to connect” to come up.
