Resolution limitations on G4 dock

[a1ssim]

Hey guys,

I have an HP Elite G4 USB-C Docking station, I have 2 1440p monitors, if I just use one of them, it's all good, but when I plug in the second monitor that's also 1440p, the max resolution I can set on it is 2048x1080 at 23Hz Max.

It doesn't matter if I push the resolution down on one of the screens, I still have the same issue on my second monitor.

Is that limitation of the dock itself or the USB-C Port on my HP ZBook Firefly 14, tested the same dock on an older laptop but I still have the same limitations.

Thanks in advance guys
