Maximum number of external screens

HP Recommended
HP ZBook 15u G5 / Ultraslim dock
Microsoft Windows 10 (64-bit)


Does anyone have any information on the maximum number of external displays i can get working with external screens connected to mu Ultraslim dock?

I've currently got 2 x HP ProDisplays P221 connected (1 x displayport, 1 x VGA) and an addtional HP w2207 (connected to the remaining displayport)

If i have internal screen open, i can only connect to 2 of the external screens, not the 3rd one

Within Intel Graphics panel it only shows 3 screens

Within Windows, all 4 screen are displayed and the display not working as the option 'Disconnect this display'. If i change the setting, i loose one of the other screens

If i shutdown the internal screen, i can use all 3 screens

is this a limit of the gpu?

The dock has folloiwing ports


  • One standard lock slot
  • One docking station cable lock slot
  • One Side docking connector
  • One VGA port
  • One LAN/Ethernet port
  • One 1Gb LAN/Ethernet port (10/100/1000)
  • Three USB 3.0 ports
  • One USB 3.0 charging port
  • One Power connector
  • One Line in jack
  • One Line out jack

You should be able to use 2 external monitors to your machine, 1 digital port on your machine itself and 1 analog port on the dock plus laptop screen, total 3. From your setup, you also can use 3 monitors (4 minus laptop screen).
