simultanues image display on 2 x 4K monitors (30Hz should be OK) - which graphics card should do the work?

[Udi Zohar]

We have very large images that we would like to display on a dual 4K monitors configurations. I do not think we need 60Hz nor gaming type requirements (imagine Photoshop type of application) I could not get a definite answer which graphics board will do the job. Do we need a card with dual 1.2 display ports? thanks in advance

You'll want to provide the monitor models. Depends on the monitors whether dual or a single display port is needed.

Any recent GPU will be able to support two 4K screens at 30hz through HDMI, Display port, or DVI.

If you want actual performance as well for Photoshop, probably want an AMD Firepro card. But to get an exact card we will need a budget, and the details of the system it is going in.

You don't need a firepro for photoshop and stuff since firepro is pricey for that. R9 295X is the only card that can do 4k on multiple monitors at a cheap price. I definitely would not bother with Titan or 980 SLI for that matter.

The GTX 750 Ti will be enough. It comes with 2 HDMI 1.4. It will run 2 4k monitors at 30 Hz. I can't find a lower cost solution than this, though there is the AMD R9 cards such as the R9 270X that is very powerful in OpenCL, as opposed to Nvidia's CUDA technology. What are your PC specs? If you have an integrated GPU such as the Intel HD 4xxx series, chances are you can already run a 4k at 60 Hz.

As mentioned above, you need to have (in this case) 1 HDMI 1.4 port on each monitor for this to work, or 1 display port and 1 HDMI 1.4 in my other suggestion I will list below. So giving us your current computer specifications will help us to help you.

2x HDMI 1.4:

Video Card: Gigabyte GeForce GTX 750 Ti 2GB WINDFORCE Video Card ($129.99 @ Micro Center)
Total: $129.99
Prices include shipping, taxes, and discounts when available

1x HDMI 1.4, 1x DisplayPort 1.2:

Video Card: EVGA GeForce GTX 750 Ti 2GB Superclocked Video Card ($119.99 @ Newegg)
Total: $119.99

I have a Gigabyte GV-N750OC-2GI (http://www.gigabyte.com.au/products/product-page.aspx?pid=4983#ov), a low-cost quiet nVidia-based card that provides 2 x HDMI 1.4 connectors that each allow 3840x2160@30Hz, as well as 2 x DVI (one dual-link), which can also supply HDMI at 1920x1080@60Hz via cheap DVI-HDMI adaptors.

I bought it because I was getting a 4K TV and I wanted something cheap while waiting for cheap HDMI 2.0 cards to come out (4K@60Hz).

Just be aware that a HDMI 2.0 screen tells a Windows system that it is capable of 60Hz, even if the card cannot support it, so the driver defaults to 60Hz, which may produce colours around text.

You have to go into the nVidia control panel (or the Windows card properties dialog) and change the Refresh rate to 30Hz for the 4K display.
