Cheapest way to add second displayport to PC?

[ult_nrg]

I've just got myself two 4K monitors running side by side but have a problem! Each monitor has 2x HDMI 1.4 and 1x displayport 1.2.

My ASUS Strix GTX 970 only has one displayport on the back, so I can't drive both monitors @ 4K 60Hz (and 30Hz, even on the Windows desktop, seems really laggy).

Is my only option to get a different 970 (or different card altogether) that has two displayports on the back? Or am I able to somehow get a cheaper card and drive the second monitor off it?

I only intend to play games on one screen (not both), and only light games at that. I do have room to add another GPU in (don't want to get something as expensive as the 970 though as a second card...would rather sell this 970 and get one with two DPs).

Thanks!

Intel GPU for 2nd screen?

That's what my inital plan was only to realise the MB doesn't have any graphics ports, let alone DP

Also am running a Xeon processor, so even if it did I don't think the iGPU would work.

Unfortunately low-end graphics cards tend to be based on Kepler or Fermi for Nvidia and pre-GCN ancient dinosaur GPUs for AMD so the chances of display port being there are slim.

Club3D had a display hub or something. Don't know about 4K but it's worth a look.

Does your motherboard have a second PCI-E x16 slot? If so, you can toss a GTX750 in to run the second monitor. Probably the cheapest option.

I looked into those, but I am still splitting off one DP which has only enough bandwith for 1x 4K screen @ 60Hz.

Yep, have room for an additional card, would adding a 750 play nice with the 970? Anything special need to be installed, or just chuck in the card and plug the second monitor into it?

Nothing special needed, just throw the card in and plug in the second monitor. Since they are both Maxwell based cards, the same driver will generally always work for both cards as well. So whenever you update the driver for your 970 it will also use the same new driver for the 750 automatically.
