Dual Monitors

Post by moman63 »

Hello,

I have 2 LG 27' 4k monitors that are connected to an Hp Elitebook 9470 laptop dockstation (HP ELITEBOOK FOLIO 9470M ULTRASLIM DOCKING STATION PORT REPLICATOR) that has 2 separate displayport adapters. Both monitors are detected by I can only configure them as 1 monitor instead of 2.

I have attached the video display from lspci. If I need to submit anything else pls advise.

sudo lshw -C video

Intel video cards are funny, it's surprisingly hard in Linux to find out what the hell exact card it is. But this should do it, copy/paste to the terminal and copy/paste the text output here (it also gives more complete system info):

Code: Select all

inxi -Fxz
However, my gut feeling here is that the machine isn't nowhere near as powerful as is needed to drive two 4K external monitors.
