Dual Link DVI

This is probhably really simple but what's the diffrance between Dual Link DVI and 2 x Dual Link DVI (Thinking of the Gainward GeForce GTX 570 Phantom 1280MB But that's Dual link DVI where as the Gainward 1536MB GeForce GTX 580 Phantom is 2 x Dual Link DVI ) I want to be running two 24" iiyama ProLite B2409HDS moniters)

Thanks Paul

More about dual link
  1. come on some one must know loads looking but no answaer ?
  2. 2x dual link dvi means that there are 2 of them compared to one. although a 570 should have 2 DVI ports which is all that you would really need.
  3. yes I realise it means it has two instead of one Can you connect two moniters to 1 x dualk link DVI ? what dose 2 x dual link dvi mean in practical terms
  4. lol it means there are 2 outputs on the card that are called 'dual link dvi' or dl-dvi for short (vs single link dvi)
  5. Dual link means it can run higher resolutions, but can only support one monitor per connector.
  6. Hang on yes I get that well what Im reading on Scan then dont make sence as some cards are described as ((the Gainwood phantom 570)
    1 x DisplayPort
    1 x Dual Link DVI-I
    1 x HDMI

    But the Asus D2CU 570 says ...
    1 x DisplayPort
    2 x Dual Link DVI-I
    1 x HDMI

    Do you see what I'm geting at the gainwood says 1xDual link DVI but Asus 2xDual link DVI ... yet when you look at the cards they both only got 2 slots for DVI type conections
  7. This is the card I'm looking at on Scan
    http://www.scan.co.uk/products/1280mb-gainward-gtx-570-phantom-40nm-1950mhz-gddr5-gpu-750mhz-shader-1600mhz-480-cores-dp-hdmi-plusf

    So if it has two connecters is one connecter single link DVI and one Dual link DVI then ?
  8. From looking at the pics Kari was kind enough to post it looks like there both Dual link DVI so poss Scan disscription **** up and it should read 2 x Dual link DV I and not 1xDual link DVI Be good if some one could take a look to conferm I'm not loosing the plot

    that's 2 DLDVI ports.
  10. Yes, that has 2 DL DVI connectors.
  11. Gainward's website says that the GeForce GTX 570 "Phantom" has Two Dual-link DVI-I connectors.

    It will handle two iiyama ProLite B2409HDS that each have a native resolution of 1920 x 1080. Single-link DVI is all that is required for each of these monitors.
  12. Thanks ever so much peoples you can see why I thought I was going Mad lol untill I looked at the pics Kari posted
  13. Everything is a dual link these days. The dual link DVI vs DVI terms are so old they have merged together. I dont think you will find a single link video card on a PCI-e.
    In short a single link maxes out at 1920x1080. To have a higher res on one monitor you need a dual link.

    You really dont need to worry abou this anymore, this is a case of poor labeling by the manufacturers.

  14. The limitation of Single-link DVI is not resolution based, it's data rate based (i.e. the combination of resolution and refresh rate).

    Single-link can even handle a resolution of 3,840 × 2,400 but only at 17 Hz refresh rate since that is within the Single-link's maximum data rate of 3.96 Gbit/s (excluding 8b/10b encoding overhead).
  15. So all this taken in presume the Gainwood Phantom GTX 570 will be a good dual moniter card for video and photo editing besides that my computers a glofied porn and Ebay machine lol.
