As the title suggests I want to power two 2560 x 1440 monitors from one graphics card.
I am just about to send my second graphics card back to Amazon, so before I purchase a 3rd incorrect card I thought I should get some advice.
My latest card has dual DL-DVI output but only supports 2560 x 1440 on one output, the other maxes out at 1920 x 1080.
Can graphics cards with two Dual Link DVI adapters (or alternately, one Dual Link DVI and one DisplayPort support the a full 2560 x 1440 on both monitors, or does that depend on the graphics hardware and not only the connectors?

You just need a video card that has two dual-link DVI ports.
The Geforce 600 series supports "4 independent 2D displays, or 3 stereoscopic/3D displays (NV Surround)"
AMD cards with eyeinfinity that have two dual-link DVI ports should also support this.
Here is an example of a card that has two dual-link dvi cables. This is not an endorsement of this product or a recommendation to buy. Just shop and look for a card that has two dual link DVI ports should be all you need.
It is possible to make a displayport connector into a dual-link dvi cable however that seems more expensive with adapters currently ranging in price from 60-$100
You could also opt for displays that support displayport 1.2 and a video card with that port as well.
"For example, a DP 1.2-enabled notebook will be able to drive two WQXGA (2560×1600) monitors or four WUXGA (1920×1200) units over a single connector, with each display acting as an independent screen with different resolution and timings at full uncompressed pixel performance with HDCP copy protection."
