A GPU for two u2711 [frustation inside]

Hi people.

I'm trying to find a suitable GPU for my needs to buy for my new PC that would allow me to connect both of my DELL u2711 and run them at their native resolution: 2560x1440. I am not looking for a powerful 3D GPU card because I'm not a gamer anymore, and I just need big screen space to work.

Some years ago I was really into HW and knew more or less everything (for domestic use) in detail, but I've been out of play for the last years and I really find myself outdated regarding hardware knowledge. This leads me to absolute ignorance when it comes to the new (so-to-speak) DVI-D and Display Port connections, multi-monitors setups, etc... and I'm kind of going crazy here (even thou I've been learning a lot for the last week).

My objective is to set up and extended desktop (no need for horizontal span) for my monitors, using one single graphic card. Because I really don't need 3D power, I was thinking that a low/mid range VGA would suit me, maybe a Geforce 610/640 or some ATI 77xx. But the "connecting both monitors to one graphic card" issue is driving me crazy. Because u2711's resolution is higher 1920x1080, I am obviously forced to use DVI-D and/or Display Port so I need a graphic card with enough display connectors.

Up to this point I think - Oh well, I guess I could connect both monitors to the "chosen" VGA either with:

  1. 2 DVI-D connectors.
  2. 1 DVI-D and 1 Display Port.
  3. 2 Display Ports.
Then I see that many VGAs come with miniDP connectors, so I guess I would need to purchase a MiniDP-to-DP cable for than, in case I'm using a VGA with that display connector. Anyway, afterwards I start to wonder if it is really possible to use option #2, because low/mid VGAs do not come with a lot of display connectors, and I would like to confirm in advance if the card I'm acquiring would allow me to connect both monitors without any problem. I am not new searching the web but, man! is finding clear info about this a pain in the ace :)

Anyway, looking for some info I start to read about Display Port 1.2 and daisy-chaining the monitors, which sounds great because if that's possible, I just need a VGA with a DP 1.2 connector, and that does not limit the offer as much. But I also read that daisy-chain it is not supported by my u2711 (because they just have one DP port), but I just don't know :(

So, I'm kinda going crazy here, mainly due to the fact that I've been off for some time, and therefore I'm standing ignorant at this momment :thumbsdown:

The PC I'm getting is an Ivy Bridge 3550 with 8 GBs of RAM, Gigabyte H77-D3H, a couple of SSD HD's and a SATA one and an Antec 300 Ultimate Gaming case and I am going to use it to work (I write, review and edit content) so, as I said, I don't need huge 3D power. I will watch some movies and listen to some MP3 also, but that's about it.

So, could anyone give me a hand here? Which VGA would you guys pick for this PC config and my needs if you were in my skin? How would you connect both u2711 to that VGA?

I would really appreciate the help. Thanks for making it this far ;)

Cheers.

PS: I'm not a native english-spoken person, so please excuse me if some of this brick reads funny :)

What you need is a video card with either 2x Dual-Link DVI connectors or a combination of Dual-Link DVI and Display Port outputs.

I have a Dell U2711 myself and on my Radeon 7970 I am using one of these Accell miniDP to DP adapter to convert from miniDP to Display Port.

The other option for miniDP to DP is a cable like this Accell Mini DisplayPort to DisplayPort Cable


I think the most foolproof solution would be to find a video card with two miniDP connectors and then get the miniDP to DP cable/adapter of your choice.

The cheapest video card on Newegg with two miniDP appears to be this http://www.newegg.com/Product/Produc...82E16814131460

I hope this helps.

Part 1) Motherboard manufacturers are stupid/cheap. While the integrated Ivybridge GPUs should be able to power two 2560x1440 monitors, it doesn't seem like any motherboard support it (requires dual link DVI and/or DP, most motherboards have single link and/or one DP).

Part 2) You could get a different motherboard and run one monitor from the DP port on the different motherboard, using the integrated GPU and get a graphics card which has DP/DL-DVI and do it that way.
Or you can just get almost any card with DP and/or dual link DVI and it will work fine to power both monitors, and there is zero hassle with either connection type.

There don't seem to be any similarly priced NV cards, they all seem to be DVI + HDMI + VGA for some reason, so the cheapest card which would run both monitors would end up being closer to £100.
If you want to go for integrated GPU + card, then any card would do pretty much, as long as it has dual link DVI. However, you would need to pick a different motherboard which has either DL-DVI or Displayport output, as your chosen motherboard does not.

Cheapest H77 motherboard with DP: (Z77 are also more expensive)

The cheaper option would be a different motherboard + cheap graphics card, as that would be £112 vs £150 for your current mobo choice + graphics card for both monitors.

Hi!

First of all, I really appreciate your help here, I just wanted to say that first :)

Hi Bull Dog.

Reading that a combo of DVI-D + DP would work (and seing that Lonyo confims it afterwards) is very pleasant :)

Thank you for the cable-adapter links, that really helps, because I had in mind prior to writing this thread a couple of 7770 (Sapphire or Gigabyte
a bit more inclined to the latter, but still in doubt) and now I can get a clearer picture.

Anyway I still think that those cards are above my needs considering their 3D power, but now that I know that I could use a card with DVI-D and DP, using each ports my monitors, I think the option range broadens.

Dual Link DVI is better, and completely hassle free unlike display port.

Hi borisvodofsky.

How so?

I understand that with DVI-D I don't have to deal with adapters, but afaik, DP is able to manage 30 bit depth color (Deep Color) while DVI-D cannot. Not that I care about this difference, because even if my u2711 can handle 30 bits, I'm not getting a FirePro or a Quaddro card, and I'm not going to work with photo editing or 2D design. Such a shame having that option at hand and not use it, but I have enough work atm :)

Hi Lonyo!

I definetely agree with part 1. The first thing I thought was to use the integrated GPU to do the job. I would have gone to a 3570K for that, probably. I think it would have been worth it (HD4000 is way better than HD2500). But then I saw what MB manufactures equip as display connectors on their MBs, and I was really brought down.

It just seems ilogical, and the only reason that I find reasonable for this situation to be as it is, might be that people with multi-monitor setups are also people with high-end GPU demands, so MB manufacturers might not think that they a market target if the include those ports on their MBs. It's just my guess. Anyway I think I am just an exception :)

For part 2, I really, really have to thank you for the detailed explanations and the options. For the MB with DP port, I think you meant this one, but reading everything that you have so kindly detailed, I get the point and now I think I see the whole picture, which it feels like a tiny golden success =)

@OP

What is your budget for a video card?
Hi Destiny.

Money is not an issue in this case, which means that if I needed to buy a £200 VGA for this, I would. The thing is that I just want to be sure that I am buying a right setup. Something that fulfills my needs and, money-wise, will last. But I don't want to end up buting something that exceeds my needs simply because that would work. I am the kind of person that hates to do so, therefore, I'm a total pain :D

Anyway, I'll think about the different options that I see here. Now, at least, I know which ones there are!

I might end up buying a 77xx because I more or less like the idea of getting "newest" technology (even if it is mid/low end) considering its "life-expectancy", but I will sleep over it anyway.

Thanks again guys.
