I'm planning on running 8x 2560x1440 displays, ideally at 60hz.
For example, say a card says it can do:
- 4x displays @ 4096x2160 @ 60hz
- 8x displays @ 4096x2160 @ 30hz
- 8x displays @ 1920x1080 @ 60hz
if I apply the following math to the above assumptions:
- 4x displays @ 4096x2160 is a total of 35,389,440 pixels
- 8x displays @ 2560x1440 is a total of 29,491,200 pixels
It would seem that everything comes down to the number of pixels that need to be handled. According to my numbers, my setup would be less pixels than the example card at 60hz. But, I don't know enough about GPU internals to understand how everything works and whether my math and assumptions are just nonsense.
Is my GPU max resolution calculation correct?

1I think it should run fine at 60Hz, though I have a question: What single card supports 8 monitors? Because if you have to run 2 cards anyway, wouldn't that off-load some of the work between themselves? However, based on Nvidia's FAQ site, only maximum of 2 monitors are supported through SLI (additional monitors can be added with a card that's not the same as those in SLI, which is still a maximum of 6 monitors). May I ask what your setup is? Very curious. – NeVMiku – 2017-04-29T23:28:04.107
@HatsuneVocaloidMiku NVS 810. Moderators made me edit that out of the question. – brian – 2017-04-29T23:33:25.077
If we take "pixels @ some Hz" as the total throughput a card can handle then yes, it should run your setup at 60Hz. Though instead of taking advice from a stranger on the internet, wouldn't it be better to ask the manufacturer themselves? – NeVMiku – 2017-04-29T23:38:02.203
@HatsuneVocaloidMiku At the time of this question, i had already made the purchase. I didn't notice the constraints until later. – brian – 2017-04-30T03:49:54.693
1You can still ask to get more information, or pretend to be a customer of interest. I've found the latter to be way more responsive in some companies. – NeVMiku – 2017-04-30T13:09:48.200
