27" Display Atlona AT-DP400 + ATI 5970 = 720p only?

After the wife was nice enough to pick up two of these displays I went ahead and ordered a AT-DP400. I needed this because the ATI 5970 only has 1 Mini Displayport.

After speaking the Atlona on the issue of the monitor not getting full resolution and only 720p he informed me that there is an issue with the EDID in the DP400. They are working with ATI and apple.

As of today they do not have a fix. Has anyone else ran into this issue and fixed it to work over Dual dvi to mini-Displayport?


This is on a PC (Running bootcamp with latest updates)
HIS ATI-5970 (latest drivers)


Thanks!
