DVI to Dual link?

It would be rare for a video card, even a low-end one, made within the last few years to not support 2560x1440. I'm using an older low-end GeForce 8400GS with mine via DVI (using a dual-link cable, of course), and my low-end Acer Netbook has no problems with that resolution via HDMI.

That's good to Hear.  Saw a configuration with the AMD Radeon 7570 1gb that I thought was 1200 px max vertically?

AMD's specifications for the 7570 say that it supports

  • DisplayPort - max resolution 3840x2400
  • HDMI - max resolution 1920x1200
  • Dual-link DVI with HDCP - max resolution 2560x1600
  • VGA - max resolution 2048x1536

AMD - RADEON HD 7570 GPU Feature Summary

Recent versions of HDMI theoretically support resolutions higher than 1920x1200, but in practice, many implementations have a 1920x1200 limit.  This is apparently one of them.

So you would be limited to 1200 pixels vertically if you were depending on the HDMI link.  This is why it is preferable to use a DisplayPort connection or dual-link DVI connection.

I found this:


It lists as specs:



D-SUB = 1 x D-SUB

DVI =1 x DVI

Yet under max resolution, it says Max Resolution = 2560 x 1600 (DL-DVI).

Does the listed DVI become Dual Link DVI with the purchase of a separate cable?

Is D-Sub the same as DisplayPort?
