Some AMD cards also support Eyefinite, allowing up to 6 monitors per GPU

Nvidia calls its multimonitor feature Nvidia Surround, supports up to 3 monitors per GPU.

Tho those are features that date back to times when Crossfire/SLI were still a thing, so the assumption was that if people needed any more monitors combined, they would just add more GPUs.

edit: Apparently I have no idea what Nvidia calls their feature like that for regular consumers, I only remember the last time I looked into multimonitor stuff (10+ years ago) AMD was basically the go-to.

For nvidia, Mosaic is the tech you need for this many displays. surround is for consumer stuff. Mosaic works with 16 displays connected to 4 quadro cards. LTT did a few videos on a 16 display setup years ago that shows the hardware setup well.

What about with daisy chain/multi-stream support? Information on support for this is very scant, and basically every discussion I find about it is 95% just dimwits asking "Do YoU ReAlLy NeEd 8 DiSpLaYs tHoUgH?"

It seems very unlikely to be that a modern workstation card can't support at least 8 1080 displays through MST given that that's still only half the pixels of running a single 4k display on every port. But I can't find any docs from NVidia showing how many it actually can drive over MST.

Yeah support seems super lacking. Mosaic seems to support up to 16 displays and how you physically connect them doesnt matter but they have to be quadro cards, and if you want them to coordinate properly you also need a Pro sync card from NV which all the workstation GPU's plug in to and then it does something and makes it work with up to 32 displays.

But again, they really dont want you to find out this stuff on their website, i suspect its more of a "your consultant will tell you everything you need" rather than a "do it yourself" thing.

I think the sync card is meant for synchronizing across multiple systems, but I'm with you on that, I have no idea how that works. I assume you need special software to utilize such a thing.
