Elitebook G6 with USB-C Universal Dock, screen resolution issue, extended Desktop

[snaky]

Hallo, I am struggling with my my 2 monitors (HP Z27i)  to get the correct resolution 2560x1440px.
Specs from Notebook and dock are clear; 2 displays with up to 4096x2160 are supported but I get only once 2560x1440px and once 1920x1080 on these monitors if I activate extended desktop.

Clone desktop is fine but not wished or usable at all

I ordered new displays, both 3840x1440px which I want to connect, as specs are telling me its supported. Therefore I replaced the notebook and dock, spent a lot of $$ and now even the old screens are not working correctly.

What do I need  to do?

Thanks!!

What is your USB-C Universal Dock ? It says 2 displays with up to 4096x2160 (that means for BOTH, not EACH). Now you get 2560 x 1440 and 1920 x 1080 you can work out the math.

Hope this makes sense.

Regards.

Thanks for your answer!

Here is the documentaton: http://h20195.www2.hp.com/v2/GetDocument.aspx?docname=c04168358&doctype=quickspecs&doclang=EN_US&sea...

Page 4, Dual Display: (2) 2.5k Displays, on any of the 2 ports -> That means to me that 2 displays with 2.5k can be connected and are working in recommended resolution.

- > Maybe HP should mention how this table content is meant,  would help a lot!

Sidenote: On the old slim dock the 2 displays are working correct, so its not a limitation of the graphic card.

Concerning my upcoming new displays, both 3440 x 1440, will they work on the old slim dock, or what dock I need to take that they show the correct resolution? (Extended desktop, not clone)

Thanks!
