I am a web developer and looking to get two 4K monitors.

I need these to run at 60hz together, what GPU (Cheapest) can you recommend. I will not be gaming at all and just need the screen " real estate"

Thank you for your time :bounce: :bounce:

I can't find any single card which can support the resolution you would need. I don't know if 2 cards not in Sli would do the trick but if they do then 2x 960's would be a good option but don't expect to do any gaming on them at this res.

thats what Nvidia say:NVIDIA GPU support for 4K Resolutions

All GeForce GTX 600 and 700 series GPUs can support 4K resolutions through DisplayPort. The NVIDIA driver automatically detects 4K 60Hz tiled format, so no special user set up is required. In order to power games at this resolution with settings turned up NVIDIA recommends GTX 780 SLI or better.https://developer.nvidia.com/4k-ultra-high-resolution-development

Yes but the OP wants to run two so 7680x2160 which seems to not be supported by a single or sli setup from what I can see. Would two non sli cards achieve this?

He is not looking for a single GPU to support 8k resolution, he clearly stated 4k. Adding 2x 4k monitors does not mean the monitors themselves will magically double their picture clarity and resolution, it is still 4k.

If you want the best single GPU option for 4k@60Hz: Get the 295x2 which can get you up to 4x 4k monitors at 60Hz with it's mini display ports.

Since you don't want the 980, how about the 970, it is $350 with the same connectors.

If you are not gaming at all, the 970 will do, just connector through HDMI and DP.

I know the 295x2 is more expensive but I added it because it is the best option out there while it is usually $1,000. If you get that, just make sure your monitors has DP 1.2, but I'm pretty sure all 4k monitors has it by now.

If you are going with the 970, get a HDMI 2.0 cable and a DP 1.2 cable, also make sure the monitor itself has HDMI 2.0, as far as I know there are few that has them.

Stretching his desktop over two 4k monitors is a resolution of 7680x2160 (like stretching over 2 1080p monitors is 3840x1080) No single card seems to support this resolution? Would two individual cards (non sli/crossfire) work, if they would as the OP is not gaming he could go for two lower cards like the 960.

As far as I know, there isn't a single cable that splits into 2 for 2x 4k monitors.

He said he needs a single GPU with 2x 4k monitors. Get the gtx 970, use the HDMI 2.0 and DP 1.2 port from it, done.

Its not done if he wants to extend his desktop over both as a single card wont support that resolution and I don't know if dual cards would either. Extending his desktop doubles the resolution of the desktop, displaying the same image on both does not. We need a clear explanation of what he wants to achieve, to me the OP is ambiguous.

While this may not help the OP, I will post this for the information. I recently built a setup with dual 4k monitors using a single Nvidia Quadro K2000 card (around $400) - works perfectly using the two DP ports, DP1.2 at 60Hz.

Would the GTX 960 work as well? I am looking for the same setup as the OP, dual 4k monitors both running at 60H, extended desktop. I am not planning on doing any gaming, just looking to maximize the resolution.

Late reply I know. I'm a web developer too, and just got myself 2x 4K monitors for the screen real estate. What - I THINK - you need is a mid range workstation card which can have multiple display ports. I literally just ordered a FirePro W5100 to solve the same problem, it should arrive in a couple days!

I tried running the monitors on a GTX 680 but because it only has the one display port it struggles. It can run a single screen fine @4K - 60hz but adding a second screen results in massive ghosting and a "rough, jaggy" feel.

I'm guessing the only graphic horsepower you need is for graphics applications like photoshop and AI, which the firepro or nVidia Quadro cards will be fine for, in fact probably better than the gaming graphics cards.

As for the cheapest option, you can get workstation cards for pretty cheap, however, I suspect you would need 4GB of VRAM to be able to handle the massive resolutions.

Anyway, if you are interested, I will let you know how my new FirePro W5100 card runs the two monitors when it arrives.

Hi Tom,

Did this work as you'd hoped? I've been trying to find out whether W5100 supports dual 4k monitors @ 60hz, but haven't been able to get a definitive answer out of Google!

Cheers,
Simon

Hey Simon

Sorry for the late reply. Been using the w5100 for a few weeks now and yes it does very well.

The only problem I have is when I wake the PC up from sleep the graphics driver likes to down the display output to 24hz on one display... something I have literally just noticed and trying to resolve.

As for performance, i'm very happy with them. I do a bit of light photoshop and AI work and both applications run very smoothly in 4k even at the same time on each display.

For the price of this card, I would recommend it over a gaming GPU, unless you want to play games on your workstation. Personally I like the fact that I cannot get tempted to open steam up and play a quick round of dota or something when i'm meant to be working!

I need to set up dual 28inch 4k monitors will the 4gb Geforce gtx 960 do the trick?

I was looking through these forums because I am having some trouble with my dual 4K setup. But these comments have me worried. I used to 4K monitors on a single GTX 780. It's a non-reference board that supports HDMI 2.0 and DisplayPort 1.2. I have no trouble at all getting both displays at 4K 60 hertz and both monitors also support 1080p at 120 hertz..


I'm not sure what you guys are going on about. All this guy needs is a graphics card that has 2 ports that support either HDMI 2.0 or DisplayPort 1.2. The maximum resolution support for these graphics cards is for a single input, meaning a single monitor.


Any non reference GTX 780, any non reference R9 290... and any gaming video card reference or non reference that came out after those two cards will support what this guy needs.


The main problem I am having with dual 4K monitors is that if I am running a full-screen program on my primary monitor at a resolution other than the native resolution of that monitor the secondary screen shifts towards the primary screen when the primary screen has that fullscreen program up. There are multiple programs out there to help get around these problems but getting to the point of having these problems is no issue at all.
