High Res High Refresh - Thunderbolt

VisualProcessor
Go to solution Solved by Mira Yurizaki,

Assuming 24-bit per color channel, 144Hz 1440p requires:

2560 (H pixels) x 1440 (rows of pixels) x 3 (bytes per pixel) x 144 (frames per second) = 1,592,524,800 bytes per second / 2^30 bytes per GiB = ~1.48 GiB/sec * 8 bits per byte = ~11.86 Gbps.

tl;dr, it takes about 11.86 Gbps per 1440p 144Hz stream. So theoretically it should be fine.

Hi,

I have a computer that is not so quiet, I could make it kind of quiet, but it will never be dead silent (as if its not there)
This is why I would like to put the computer in another room and cable in my triple 1440p 144hz monitors and keyboard/mice/USB

I don't know if the capabilities of thunderbolt are good enough to give me triple 1440p 144hz monitors through a single cable. Has anyone done anything similar? Might you have experience with thunderbolt and can recommend a product(s) So I can take this project forward.

If I did my math right, 1440p@144 Hz requires roughly 16 Mbps. Thunderbolt 3 has 40 Gbps, so not enough for 3x 16.

 

~edit: Not sure if theres even a product that could tunnel 3 displays + USB through TB and split them up again at the other end.

What If I run one thunderbolt optical cable per monitor?
Is there really nothing out there that will do ~60 Gbps?

Theoretically: what about interfacing with fiber cables that go ~100Gbps, say I will buy such a cable and interface for display port to go through a fiber controller

Just as a note, as a general rule transmission speeds (data per unit time) uses decimal prefixes, not binary :)
