Query: Trouble with Dual Link D-DVI

I bought two of these cables to allow for the height of a standing desk. Worked great for 2x 22" single-link D-DVI monitors for a few months.I just updated to a dual-link-required 2560x1440 monitor and neither cable works. The dual-link D-DVI cable that came with the monitor works fine. I'm not sure if it's a length thing or if the manufacturer is just selling broken dual-link cables, but if you're specifically looking for dual-link D-DVI, beware.
