Question Does anyone use a DP splitter?

[Lemond2023]

"The main advantage of DisplayPort is the ability to output to multiple displays through Multi-Stream Transport (MST). You can do this by daisy-chaining compatible monitors over DisplayPort or by connecting a DisplayPort MST splitter."

I connect PC to three monitors. Does anyone use such a splitter?

 

[hotaru.hino]

I've only used it in some occasions, but otherwise I just plug in each monitor into its own port on my graphics card.

The main limitation to MST is that you're limited to the maximum bandwidth the single port. So if the port is only good for say 3840x2160 @ 60Hz and you plug in a 4K monitor, you can't add anything else down the chain. Though you can use this to connect up to say 4 1080p 60Hz monitors.

But does one have three different screens (i.e. extend and not duplicate)?

Are you asking if you can combine screens to act like one?

Extend: each screen has different contents. https://support.microsoft.com/en-us...-windows-3d5c15dc-cc63-d850-aeb6-b41778147554

Yes, MST hubs allow you to have multiple independent displays, not mirrored.

So what I want to do is as follows:
(1) I have PC in Room A.
(2) I have three monitors in Room B.
(3) I want to connect these monitors in Room B to PC in Room A while three monitors have independent displays (each monitor shows different contents)
(4) But I want to have three cables directly connected to DP port of PC.
(5) Can a splitter help? if so, which one?

Yes you can use a splitter to do this as long as it's using DisplayPort MST and all three monitors won't consume the bandwidth of a single DP port.

I only do office work and coding. No video games. Then DisplayPortMST for three monitors work for these work?

What's the resolution of the monitors you want to use?

What's the resolution of the monitors you want to use?

Thank you. 2560*1440

 

[hotaru.hino]

Thank you. 2560*1440

Assuming they're all 60Hz. this should be fine as long as you're not using a GPU from before around 2012.

I am checking Amazon. But how does one distinguish between splitter and switcher?

A switch will have buttons or some remote. A splitter won't. But it doesn't hurt to read the product literature carefully.

I find a hdmi splitter https://www.amazon.com/Splitter-Fki...n+3+out&qid=1683432526&sprefix=,aps,81&sr=8-3
Will this one work?

 

[Glenwing]

No, HDMI does not support multiple independent displays from a single port.

Then what will work? I cannot find a DP splitter of one to three (with a good Amazon rating).

What part of the world do you live in? We could try to help find something, but we need to know that to make sure we can find something that's available in your neck of the woods.

While they're not cheap, StarTech provides multiple DP splitters. Curiously they also have a DP to HDMI thing. However I probably wouldn't get hat since it's likely using a converter chip and it'll be limited to 3x1080p 60Hz.

This is my situation. So I wish to have female to female splitters. I do not see it from StarTech. Please advise.

Nobody makes those because the expectation is you're going to plug the splitter closer to the source. Just buy a DP extension cable like https://www.cablematters.com/pc-1307-179-active-displayport-14-extension-cable.aspx
