Welcome to the EVGA Forums 
 
Short answer Seems to be NO - (3 reasons listed ---> found on Nvidia link listed below)

 
1) "Max of 4 displays can be used simultaneously"

 
2) "Maximum number of displays: 2-4 in Surround, 1 Accessory Display when using 3 or less displays in Surround"
 
3) "Maximum Resolution: 11520x2160"

Hi All, I'm helping a customer spec out a multi monitor array.  He currently has an evga 1080 gtx card.  We want to run 6 dell Dell Computer Ultrasharp U2415 24" monitors in traditional landscape in a 2 tall by 3 wide array.  We'll be running these in a display port daisy chain setup.  Can we run all 6 of them in a daisy chain off a single cable from the back of the GTX card?  When doing this, all six monitors will act as a single large monitor, right? 
 
dell's monitors: 
 
Then on the left and right side of the main array, he wants to run two 24" monitors off HDMI and/or DVI from his GTX card in portrait mode.  
 
Will his 1080 GTX have the horsepower to run this type of setup?  He's doing some basic video editing and lots of website building.
 
 
 
6 monitor stand we're looking at: 
 

I believe what you're asking is can that many monitors be supported via DP 1.4 using MST or multi stream transport. Have you considered an active hub?

Thanks Cool GTX for the info.  
 
Heavy Hemi, yes I guess that is what I'm asking.  Can we daisy chain a 2x3 set of 6 monitors via the cards DP 1.4?  If not, what is the max that we'd be able to do?  The card has 3 Display ports (and 1 HDMI and 1 DVI).  It would be great, even if I have to do the top row of 3 off one DP and the bottom row of 3 off another DP.  Then the HDMI and DVI for the two outer portrait 24" screens. But I'm guess that's not possible?
 
What is an active hub?
 
 
What is necessary to setup the array I'm looking for?  Do I need a second GTX 1080 and run in SLI?

SLI has nothing to do with your configuration. What is supported via daisy chaining is what is stated by the DP 1.4 spec.

Your asking to place 1/6 of total image on each monitor ?
 
1)  I think your question of Running 6 Monitors (landscape) AS One larger monitor (three columns of two monitor rows) is the first technical issue. 
  
 
2)  The second technical issue --> can you simultaneously support two additional monitors in portrait mode (Accessory Displays)

(excerpt - Best Answer)
The MST hub allows multiple DisplayPort monitors on a single DisplayPort connector, splitting the available bandwidth between devices.
The HUB isn't a display output device as such, the monitors are still seen as outputs by the graphics card.
Using an MST hub does not get you around the 4 display device limitation on Nvidia cards.

Nvidia only supports up to 5 monitors in 2D surround on their consumer cards, so it's not possible to run the 6 displays in surround without additional hardware. With two Nvidia cards you could run all 8 displays (4 per card), but they will be treated by Windows as 8 separate displays.
This is an area where AMD actually has a big advantage, Eyefinity has supported 6 monitor configs for years now. 
 
I'm a big Nvidia fanboy but AMD would serve you better here (as Nvidia literally can't do what you are asking). As a 1080 is way overkill for just video editing and website creation, I'd suggest selling the 1080 and getting something like 2 AMD RX 550 cards. 

Thanks so much for the clarification. I was wondering about switching the customer to an AMD for the eyefinity and just going with 6 instead of 8 systems.  If we were to go with twin Nvidia cards, it sounds like if I daisy chain via display port, I can still only get 4 of the 6 main monitors to be a "single display"?  So with what you all have told me and the other reading I'm doing, the only reasonable way to get the 6 displays to act like a single display is via and AMD eyefinity card.
 
If we go with an AMD card for the 6 daisy chained displays, can we use his current Nvidia card to drive the last two?  I know it is kind of like mixing oil and water or skittles and M&M's.
 
Thank you cool gtx for the links, this is basically what the customer is looking for:

Can you use an 85 inch 4K TV as your master display ?

Thanks for the info, I kind of figured that mixing AMD and NVidia would be a poor idea.
 
As for the large TV, the customers pretty steadfast on wanting the multi display instead of one large.  Plus 85" TV's are about $5g's
