3rd Display in Eyefinity: using different type of monitor ok?

I'm creating a 3 monitor Eyefinity spread with 2 LG 30'' monitors and (would like to add) another 30'' monitor from Dell. All the monitors of course run the same resolution, but I'm wondering if that will create any unforeseen problems with the graphics card?

I'm assuming that, other than the fact that the Dell monitor is newer and has better color correction, etc., I shouldn't experience any problems?

The GPU is a BlackEdition 5970 4GB Eyefinity 6 (6 MiniDP ports).
