I just purchased an HP Spectre x360 as a machine for my home office. I also purchased 3 27 inch 1080p Samsung monitors. When I'm in my office I prefer to use my external monitors. The only problem is I'm having issues driving the third one (technically the fourth because the laptop screen counts as one although I'm fine disabling it). The laptop technically has an NVidia card but I'm assuming the limitation is the intel on-board graphics.

I'm using the onboard HDMI for monitor one, a J5 create USB-C hub w\ HDMI dongle for monitor 2, and an insignia dongle for monitor 3.

I'm an IT guy but never got too deep into displays.

  • I really doubt your laptop is able to drive three displays at the same time. If it's important that you have three I would recommend getting a desktop with a decent graphics card. That being said, can you drive the other two from any combination of the outputs? Or, in other words, are you sure that all three display outputs work and it's just not running three monitor, or is it possible that one of the outputs just doesn't display anything regardless? – Layne Bernardo Oct 29 '18 at 19:56
  • @LayneBernardo Will a docking station allow me to drive 3 displays? I see them advertised as driving 3 displays. There's one from pluggable. How much does this depend on the capabilities of my laptop though. – CAnderson Oct 29 '18 at 20:12
  • HP doesn't make laptops with "true" docks anymore - real docks have a dedicated docking connection, generally with more functionality than a standard USB port. Any dock you find will be a port replicator - essentially just a USB hub. I wouldn't think it would have any effect on your ability (or lack thereof) to use multiple monitors except that it would give you more ports, but I might be wrong. HP's support forums are absolutely useless on this topic. Like I said, I would verify that all three of your display outputs are independently functional before trying anything else. – Layne Bernardo Oct 29 '18 at 20:20
  • You should be able to drive your laptop monitor and two externals, but you are limited to that. 3 externals is not possible off the graphics card in your machine. There is a solution, and that is to get USB to HDMI dongles. These are independent of the hardware limitation. Some people have reported screen lag with them, but I've had good experiences with them in the past. – Narzard Oct 29 '18 at 20:22
  • @Narzard - Not sure how this is working but I'm using a J5 create mini doc with 2x HDMI on one USB-C and the onboard HDMI. I now have 4 displays, 3 external one onboard. The problem was when I had a J5 hub w\ one HDMI on one USB-C, an inisgnia USB-C to HDMI on another one, the onboard HDMI, and the onboard monitor. The J5 with 2 HDMI ports installed itself as a graphics card. – CAnderson Oct 29 '18 at 21:22
