ATI 5570 with a DVI, and a HDMI/VGA shared RAMDAC. 42" LCD as the srimary, 32" as the secondary. 42" is always identified as the primary. If the 42" is in solo, it's ID'd as 1. Popped in the 32", and the 42" gets ID'd as 2.

Tried swapping inputs between the two monitors and the same thing happens.

I've deleted registry keys, run every automated display registry setting cleaner I could find, re-installed drivers, re-enumerated, etc, etc, etc...noting.
