External monitor flickers through HP G5 dock
I have a MacBook Pro 1029 Intel i9, it is connected to a HP G5 dock via the USB-C connectors.
The G5 is connected to an external monitor, I have tried both HDMI and DisplayPort.
In both cases, the external screen flickers, turns off and on every few seconds. A second monitor is connected through an adaptor on the MacBook (+HDMI) and has no issues, so it has something to do with the G5 Dock.
I can not update the firmware as there is no iOS software on the HP website. Is there a way to fix it?
MacBook Pro 16″, macOS 14.6
