What are the specifications for a multiple displayport monitor setup?

I have a desktop computer with displayport. I heard it was possible to connect 2 or even 3 monitors to it.

I heard not all displayport monitors can be chained like that. Which specifications do I need to look for?

EDIT: THANK YOU EVERYONE. YOUR INFORMATION HAS PUT ME ON THE RIGHT TRACK.

Have you checked on the back of the PC? Most desktop PCs have the ability to connect multiple monitors by default.

Seems to be one displayport and the rest is mostly usb ports

Thorry84 ,

Ah that’s too bad. Usually there is at least a HDMI or something extra. If you want you can post a pic for a second opinion, but I trust you if you’ve checked.

Back of computer

First time posting a picture. It shows the computer back. Do you see anything where I can plug in another display?

Thorry84 ,

Nope, you were totally right, only the single DisplayPort port connected to the onboard graphics.

NemoWuMing OP ,

Thanks for taking the time to look at it. All of you guys are making Lemmy a great place.

You need to have a monitor that supports daisy chaining, so it has an input DP and an output DP. Ive found them quite rare to be honest, I haven’t come across them often.

My Samsung monitor has it, and is usable for both the DP and USB-C ports. It’s there as it has a notebook docker in it, which can be repurposed to a normal USB hub on desktop.

First thing to check is if your GPU supports Displayport 1.2. Because anything lower will not allow multi-stream at all.

If it does, you have two options:

  • One of your displays supports daisy chaining, so it has an output port that you can connect to your 2nd display. The last monitor in the chain doesn’t actually have support dasiy chaining.
  • You buy a MST hub, which is an adapter that connects to your display port and turns it into multiple displayports to which you can then connect your displays individually. In this versions none of the displays have to support displayport 1.2 just your GPU.

Also keep in mind that the maximum number of monitors depend on the resolution(s) you want to use. Don’t expect to be able to have a monitor @ 4K in your chain for example. displayport.org/…/driving-multiple-displays-from-… has a table with some examples of resolutions and the corresponding maximum number of monitors you can add to your chain.
