Max number of monitors on Nvidia Card, my AMD is 3

According to Nvidia's specs page, the 980ti can run 4 monitors:

Which R9 290X are you rocking mate? My reference cards can run 4 monitors each (2 x DVI, 1 x HDMI and 1 x DP to DVI using Active Adapter) and I spent a few months proving it did. :) I've since moved one of the monitors onto the onboard on my system as this proved more compatible with some games, but the cards definitely ran 4 each without needing an MFT hub.
 
I have 2, ones Asus Radeon r290x Direct CUII (this is the monitor driver) and a reference 290x with custom cooler. Its in crossfire for gaming so I dont want 2 separate cards.

I am currently running:

DP - Phillips 40" 4k 3820x2160

DVI-D-1 - Dell 30" 3008wfp 2560x1600 (used to be display port but now DVI-D)

DVI-D-2 - DGM 27" IPS screen 2560x1440

HDMI - nothing currently

I wish to connect my old/other 27" IPS screen at 2560x1440 placed above the 40" screen, but that is ONLY DVI-D connection, the DGM screen has HDMI in but I tried that and it wouldnt run at 2560x1440 properly (any idea why?)

Thanks
 
The problem is probably due to the hdmi port not being a 1.4 port on the monitor. so it most likely cannot accept a signal any greater than 1920x1080@60hz you can try a custom resolution of 2560x1440@30hz if it is just desktop work.

if you have two card, you should be able to run two of the monitors off the second card to split the load.

the only other option is to use a Display port MST hub, then run the two displayport monitors off the hub and use the DVI on the other two. should be cheaper than buying a new card entirely, can also run 5 monitors then since most hubs are triple heads.

Darn, its Ivybridge-E so no on board graphics unfort.

So a 3rd AMD card then if I can find room ? Will that do crossfire + 4th monitor ok ?

The DGM monitor is DGM IPS-2701WPH, any ideas of the HDMI spec? trying to find it now

EDIT: Found it can only accept 1440p over its display port and also DVI-D but NOT HDMI :(

Ah i see, i guess the only option is the MST hub for the two displayport cards, they sell them on overclockers.

https://www.overclockers.co.uk/showproduct.php?prodid=CB-017-SR may just need a mini to large adapter too, but i dont know if it comes with one in the box.

handy to have anyway, even if you change cards in future since you can use it to have 6 monitors.

Thanks but it sadly says:

"Supports resolutions up to 2560x1600 on each display"

So no use for my 4k screen :(

It's not top top priority at this stage but right now it looks like at the end of summer im going to have to sell up and go Nvidia which will just work with 4 monitors + they have more than 1 display port so am sorted.
 
You could easily get an amd card that works with 4 monitors, just look for one with multiple display ports. But up to you bud, is a shame about the MST hub, i forgot that one of your monitors was 4K when i looked for it.
