Hello everyone
I bought the docking station and would like to connect 2 monitors with DP. My Macbook Pro 2020,13" four thunderbolt,3 ports supports a maximum of 2 monitors with 4k. My problem: I connect everything, but the Macbook only recognises one monitor, the second is mirrored. I can't see a 2nd monitor on the Macbook either. If I connect an external hdmi port to the Macbook then it works, but with a reduced resolution. Is there a way that I can connect both monitors to the docking station with DP and connect them to the Macbook? What can I use the passthrough on the back of the station for? I hope someone can help me so that I can use both monitors.
To connect both monitors to the HP Thunderbolt Dock 120W G4 via DisplayPort (DP) and use them with your MacBook Pro 2020, there are a few things you should keep in mind:
## DisplayPort connectors and daisy chaining - The HP Thunderbolt Dock 120W G4 supports up to four 4K monitors, but there may be limitations with MacBooks that only support Thunderbolt 3. For independent monitors, you may need to daisy chain the monitors if your monitors support it. This means that you set one monitor as the primary monitor in the chain and the other as the secondary monitor.
## Connection via the docking station - Make sure that your monitors are connected to the docking station via the correct cables. The docking station has two DisplayPort connectors, but if your monitors do not have DP passthrough, you may need to use other connectors such as HDMI or a combination of DP and HDMI.
## Passthrough on the back of the station - The pass-through on the back of the docking station is not directly related to the display, but rather to the network and power delivery functions. The RJ45 Ethernet port and the power delivery functions via USB-C are examples of what can be used via the passthrough, but not for the display connection.
## Firmware and driver updates - Make sure that the docking station firmware and drivers are up to date. Sometimes updates can help to solve connection problems.
If your monitors do not have a DP pass-through function, you could alternatively connect one monitor via DisplayPort and the other via the docking station's HDMI port. This could affect the resolution somewhat, but it would be a possible solution.
It is also advisable to consult the manufacturer's specific instructions or forums to find specific settings or updates for your specific configuration.
