HP Elitebook 840 G5 Dock to run 2 monitors running 2560x1440 @ 100p Hz

[YC33]

Hello

I have an HP ELitebook G5 Laptop (ProdID 4RZ33PC#ABU) running Windows 10 Enterprise, with an Intel UHD Graphics 620 adapter and running 2x Samsung C27JG50 monitors, connected to an  HP 2013 UltraSlim Docking Station via individual DisplayPort cables.

Currently, I am running 1 monitor at 2560x1440 @ 100p Hz and the other at 2560x1440 @ 60p Hz as the system am unable to run both monitors at 100p Hz.

Is there anyway to run both monitors at 100p Hz (or higher)? When I try to change the second monitor to run at 100p Hz in the Intel Graphics Control Panel, the screen locks up. If I use Windows Display Settings, it does not even give me the option to select anything greater that 60p Hz.

I spoke to Intel and they believe this is caused by a limitation of the current dock. If that's the case, is there a different dock I can use that will allow me to fully utilise the monitors' capabilities?  I'm not sure exactly which docks are compatible with my particular laptop.

Thank you in advance.

I don't need expensive monitors therefore I use my old DisplayLink Certified Lenovo USB-A dock with 2 FHD @60 Hz monitors for my 840 G5 (I only use it for this forum).

In your case, please read the following list. The first one may  meet your need
