I am trying to set up my computer to use a three monitor set up i check online and the specs should allow for it I am using a docking station an three of the same monitors but it is not working ive tried another laptop and it has worked but i can’t get it to work on this one. It recognizes all 3 monitors but only displays on two of them.

So is it possible to have three external monitors connected to it is there a software fix to this or can my computer just not handle it?

Your machine only has 1 USB 3.1 Type-C™ Gen 1 (Data Transfer up to 5 Gb/s, DP1.2, HP Sleep and Charge) port. I did ask you HOW do you connect  3 external monitors to your machine ? Do you use a docking station. What is it ?

Regards.

[Mthunt]

I don't think wd19 dock is from HP, it is not compatible with your machine. The following document shows HP docks and they also do not fully compatible with your machine

Dell's website says that it should be compatible

@Mthunt 

Do you believe what Dell is saying. Can they prove its product is compatible with HP machines ???

I dunno I guess I’ll ask dell support if they have any ideas if it is an laptop issue or a docking station issue.
