Why is a card like the gtx 480 only able to support 2 displays at once?

post #1 of 13

It has three ports in the back, so why won't it work with three monitors like the 5xxx series and 6xxx series?

They want you to buy another card and SLI before you can use Surround?

Which isn't a bad idea really, since if you use Eyefinity on some of the lower end ATI cards (ie my 5770) you really have to play on pretty low settings. Nvidia was also pushing 3D with their surround, which puts even more stress on the cards.

but yes, AMD giving you the choice to use Eyefinity on a single low end card if you want to is a nice thing if you only want to use 3 monitors for workspace and not gaming.

Although on AMD cards there's also the issue of needing a Displayport to DVI/HDMI adapter if you don't have a Displayport monitor, but that has been pretty much solved by the recently production of super cheap adapters. When Eyefinity first came out those adapters were around $100, now you can get one specifically made for Eyefinity for around $20.

As Redmist stated - yes, there really is kind of no idea in more than 2 monitors if you don't use really high end cards anyway. Eyefinity is in my opinion waste of money for lower end cards, as you don't use it at all. If you use work applications you'll probably use professional cards.

I mean, is there like something in the software that makes it not support three? Or is it something in the hardware its self? Could you mod it so it supports three?

hardware, u can't mod it, but there are some display splitters if i'm not mistaken but in that case you better just buy another 480 since your power supply can handle both

Guys, the question is to discuss WHY nvidia havn't allowed it, not manning up

Could be for profits.
Could be a silicon issue.
Could be a chipset.

Seems that ATI/AMD built the eyefinity thing from the ground up.

They should really enable it for just 3 standard monitors (not surround)
post #9 of 13
I'm pretty sure it has something to do with Display Pipelines? Cards can only have 2, which AMD got around with Eyefinity by using Displayport? something like that.
