Is it possible to inject three display port signals into one thunderbolt cable? I am having a hard time finding a 3 input (display port) 1 output (thunderbolt) pcie card.
Is this something thats actually done? or do I need one thunderbolt per display port?

Hypothetically... you could put one of those DisplayPort Multi Stream Transport splitters on the far end, and that might allow for three DP streams. But I don't know much about DP and Thunderbolt together.

Displayport MST hub would be the closest thing that exists, but I'm not sure what it really buys you.

Unless you have some sort of limitation that prevents you from running multiple cables, discrete cables is the way to go.

Let me just make sure I'm understanding. You have desktop system, with a motherboard that does not have thunderbolt natively. You want to be able to run a single thunderbolt cable to a triple monitor set-up and thus you need some kind of adapter to allow you to run thunderbolt from your desktop to your monitors with inputs from three separate displayport outputs on a video card?

 

If I'm following you correctly, that's not how thunderbolt works or is meant to work, and if you're going to be using these monitors for any kind of gaming, thunderbolt in general won't have enough bandwidth for the refresh rates you likely want from each display.

From an earlier forum post, I was told that 1440p monitors running at 144hz need about 12Gbps, with thunderbolt 3's capability of 40Gbps, I see no reason my setup (like the one you mentioned, Rob) cant work. Unless the hardware isnt there, which is why im asking the forums if the hardware exists.

Honestly I cant imagine that some sort of multipurpose protocol/cable (usb 3.2, thunderbolt, usb c?) hasnt been made to handle such needs. If anything, a fiber cable would have enough bandwidth to work here. I just am looking for that product right now, the one thatll convert my display port signals (3 of them) to one data line.

If thunderbolt can take mouse/keyboard/display port though one cable, why cant it take a few more display port signals?
