Multiple Display - HP ELITEBOOK 840 G4

[EbyEaso]

Hello,

I need assistance. I'm using ELITEBOOK 840 G4. I'm trying to connect multiple display to my laptop using HP Ultra Slim docking station.  I have connected already 3 monitors using 2 Display port and one VGA. Is there a way I can connect one more display/TV also? Can I use the C output from the laptop? Does my graphics Card need to be supported for this?

Graphics - Intel(R) HD Graphics 620.

Currently using monitors - HP ZDisplay (2 no's), Dell SE2719H

On another note - When I used two HP Elite Display E272Q with Dell Display, Only one of the two was working. But If I use two ZDispay. All three will work.

So is there a way I can connect 4 display with my current graphics card.

Thank You.

Hello

840 G4 USB-C port is a basic USB-C, so there is no video signal on it.

if you want to have more monitors you can buy the HP Universal Dock G2 from HP. that docking has a DisplayLink graphics card able to drive two monitors up 2 x 4K 60HZ.

840 G4 is able to drives

are you using HP Zdisplay or Elite Display ?  Elite E272Q has a resolution of  2540x1440 , Dell monitor S22719H has 1920x1080. 

Processor includedintp 840 G4 is a 7th generation and maximun can support up to 3 displays , included the internal one. if you clode the lid , it should be able to driver up 3 external.  Plus other 2 if you have anHP Universal Dock G2.

Hello

which is the resolution of the two Zdisplay ? if they are 1920x1080 you have th answer .

PC can  support up to 3 1920x1080

PC can't support 2x 2560x1440 and one 1920x1080. Elite Display resolution is too high.
