Hi new here , I'm a stock day trader . I have at the moment 3 x 2k 27" monitors running off a EVGA GTX970 sc. Im looking for another screen or two .
I have a 40" 4K tv in one of my rooms that I plugged in to the GTX970sc and I love the display . Everything is the same size as the 2k tv but on the 4K at 40 " I have more room to work on for my charts .
So my question is how many 4K TVs can I connect on to my GTX970sc . I will Not be doing any gaming at all . It's Only a trading computer.
Ideally I would get 3x 4K TVs .
If the GTX970 isn't good enough what is ? GTX980?

Thanks for looking

I was able to run 2 3840x2160 monitors at 60hz from a gtx 980, plus a 1080p display, I haven't been able to test if 3 of them would work, or not, but my best guess is that it likely would, there is a chance however you'll have to drop the refresh rate down to 30hz however, but I'd be surprised if it couldn't run 3 at at least 30hz, however, if a 970 has a much lower pixel clock, it could be different.
 
that said, the limiting factor and specification you'll want to know is "pixel clock" that's how many pixels it can push, you'll need at least a ~1500mhz pixel clock for 3 4k displays at 60 hz, or ~750mhz for 3 at 30hz
 
unfortunately max pixel clock isn't a commonly listed spec, so that might be hard to find and nail that detail down.
 
edit: did a little digging, and it seems the max pixel clock for any maxwell (gtx 970, 980, etc.) card is 1045mhz, not enough for 3 4k displays at 60hz but 30hz should work I think.
If it doesn't you can also get a second card to run the third (or even 4th) monitor I think. provided there is a second PCIe slot that can take it.

there's a difference between the core clock and pixel clock, they are two different things. Core clock(both base and boost) affect how fast the graphics card is when it come to rendering and other GPU related tasks, pixel clock is all about what it can push over the display connections, regardless of how complex the process is of creating that image.
IE if you're running a high end game, it has to first create the image, then send it. the core/GPU clock affects how fast it can create an image, and the pixel clock is how fast it can send it. so if you're creating images that are fairly easy to make (like 2d graphs) it won't take a ton of work on the GPU's processor, but it'll still have to send that data to the monitor, and it can only do that so fast.
 
edit: forgot to mention there is a lot more to how powerful a GPU is that core clock, that's just one of the factors in that type of speed, and shouldn't be too important for 2d images at this level of GPUs.

N1okh
That's just blown my mind lol Is pixel pipeline the same a pixel clock ? As the gtx970 has 1664
I'm just wondering is there a way to calculate if 2 x 4ks TVs will work on the gtx970
And will 3 x4k TVs work on the gtx980 at 60hz , when i had one at 30hz the desktop was flickered when I opened start menu on Windows etc so needs to be at 60hz.
And yea its only 2d I'm using

Pixel pipelines is yet another stat, as confusing as that is.
 
for number of pixels needed, you take the resolution (3840x2160 for 8,294,400 pixels total for your average 4k/UHD tv), then multiply by the refresh rate (60) and you get how many pixels are needed a second (497,664,000). do that for each monitor and add that up and you get how much you need total. Also make sure that the TV you are using supports HDMI 2.0, or displayport (though displayport for TVs is pretty rare) You can do it with older 1.4 HDMI, but it requires downgrading the color info to do it, which may or may not be a big deal depending on how critical it is to see differences in color. If you are looking at say a graph with dozens of lines, some close in color, it might make a difference in how easy it is to tell apart. that said I haven't tested it, so don't know for sure how significant the color differences is.
