GTX 670 and Triple Monitors

[Tae___]

I have following set up:
Graphic Card: GTX 670 FTW
3 Monitors: 1) Apple Cinema Display 27"; 2) Dell P2415Q; 3) Dell P2415Q
Connections: Apple Cinema Display connected to display port (via adapter); one of Dell connect with standard HDMI cable; the other Dell connect with "HDMI to DVI-D" cable, with HDMI side connect to the monitor.

Now,
when I set all monitors at 2560*1440 resolution, I can only set 2 of the monitors at 60Hz and I'm forced to set the 3rd at 29Hz. So I now set the 27" at 2560*1440 and 2 Dells at 1920*1080 so that I can have all 3 monitors at 60Hz.
My question: do I need a better graphic card to have all 3 monitors at 2560*1440 AND 60 Hz? Or Is there something I can do to fix this? I think it might have to do with the cables but I'm not too sure. Please let me know.

Best,

You need to be using display port for the other two!

Anything above 1920x1200 @ 60Hz requires a dual link DVI or displayport connection (HDMI 1.4b can do some modes, but needs 2.0 for many)

What's the point in having 4k monitors if you're running them at 1440p? If I was in your situation I'd upgrade to a graphics card with at least 2 Displayport connections so you can run all 3 at full res 60hz.

The 670 supports MST, so you could get something like http://www.newegg.com/Product/Product.aspx?Item=N82E16815158403 instead. If he's not gaming it's cheaper to get the mst hub

Hi basroil,

Thank you so much for your answer. I don't know much about cables and dual links.
Would you please help me and tell me exactly what cables I need to purchase to make this work?
Thank you again!

You still can't run the 4k monitors at native res 60Hz though :/ It just pains me to see the extra pixels going to waste haha. You did solve the problem he asked about though.

You have one DP and one DVI dual link (currently used by the apple display). Just buy the MST hub from the link above and it should just work (and two DP cables if your monitors didn't come with one)

No, you'll still need to use Displayport. That one won't need the MST hub, but you still need to connect via displayport

He was running the Apple cinema on DP, so he'll need the MST hub, 2 DP to DP cables, a DVI-D to DVI-D cable, and a DVI-D to thunderbolt adaptor right?

MST hub, his current adapter, one DP to DP mini, and then the DVI DL to DVI DL cable (NOT a DVI D to DVID, that would be single link)

Apple and one dell are plugged into the MST, second Dell with DVI DL cable

Ok. I'm going to purchase what you suggested. It's almost $100 so I figured I drop $300 more and just buy a brand new GPU. I guess if I still need this MST hub, then there is no reason to upgrade it.

You didn't read the post correctly. You do NOT need the hub with the 1070, and can instead just plug all the displayport connections directly. The card is a huge improvement over your current one and very much recommended if you intend to game at 1440p or higher!

If you're not gaming get a 1060 and save yourself the $200 for the same set of displayports (it still has 3). If you are gaming then enjoy your new card haha.

Both will play Dota 2 at 4K just fine. What other software do you use?

No need for even the 1060 then! http://www.newegg.com/Product/Product.aspx?Item=N82E16814487204 has the required ports and should handle Dota at 1440p just fine!
