2560x1600x2+10809 - Page 2

post #11 of 27
I'm using a GTX 670 and sometimes triple monitors (2560x1600, 2560x1440, and 1920x1080).

I really don't think any GPU with over 512mb memory is going to run into any bottlenecks on the desktop, even watching a video. You are going to want the cheapest card with the outputs you need (sorry don't know exactly which card that is tongue.gif)

I normally don't recommend one GPU manufacturer over the other, but my old ATi (AMD) setup had a similar problem to what you described. It turned out the cards were downclocking way too low in 2d mode to save power, and couldn't drive the multiple high-res displays properly. For this reason, I would recommend getting an Nvidia card instead.

The PNY GTX 670 that I posted has 2 x DVI-DL connectors.

The Gigabyte GeForce GTX 650 Ti has them too (2 x DVI-DL)

And like the AlphaC member mentionned, all GTX 660 has 2 x DVI-DL outputs.


If you are aiming at photography and smooth multi-monitor support, get the PNY GTX 670. At this price its a steal. For a limited offer.

My friend at work has this card and does almost exactly as you are asking about in the OP. Mini DisplayPort also supports up to 2560x1600, and there are two of those ports on the card. Is there a reason you haven't mentioned using anything but dual DVI out?

Thanks Crazy9000.

 

This is yet another potential bottleneck that is not exposed in the specs for these cards. I have been starting to think the multiple 2560x1600 means multiple cards even though they make it look like it's not the case.

This is not true, the GTX 670 will do all your work you need to do. thumb.gif

He is looking for a card with 2 x DVI-DL, without needing to spend an extra 100$ for a miniDP tp DVI USB Powered adapter. (for resolution higher than 1200p such as 1440p or 1600p

Hi buffsportsman. I didn't think that Displayport gave me any advantages in the pixel rate. Just ability to string dsplays in daisy chain. You're probably about to tell something else I didn't know. wink.gif

I forgot to mention I'm using Display port, DL-DVI, and HDMI. Display port does make finding a card much easier.

I don't see why you couldn't just use the two DL-DVI ports and then HDMI for the 1080p screen. HDMI>DVI works great on 1080p if needed. Just make sure the card really has two DL ports... many have a single link and a dual link.

I'd advise against DP>DVI adapters. They run up to $100 for good ones, and people still have issues with them.

Someone mentioned it before, but do you have the hardware to support a second 7750?

Damn, I always forget about the special adapters. I use a $20 HIS adapter for my 1080p monitor, but I just looked to only find out the max resolution they support is 1200p. Oh well. Just thought I'd try to help. thumb.gif

KaRLiToS, I think I looked at all the 670s that Newegg has currently and pix of the port end show only one dual-link port (the one with the little metal cross-pin.
