As far as I know, Refresh rate is fixed by the RAMDAC. Not the colour settings, but the colour setting DOES effect the resolution.

i dont understand it.. someone from Rage3d even emailed ATi and got "60hz at 2048x1536" from them..

yet sites like newegg list 85hz @ 2048x1536 ..

now all of a sudden on ATI's page it's listed as 2048x1536 @ 85hz..

so blah.. who knows

Who knows? Perhaps it was early driver settings, a simple error (typo like), or perhaps 40-bit RAMDAC's as opposed to 32-bit accounts for the difference?
