Monitor refresh rate on mac pro

Hi all,
I have two LG monitors (a 22 inch W2242TQ and a 24 inch W2442PA) connected to my 2009 Mac Pro. The W2242TQ is connected by the mini DVI port and the W2442PA to the main DVI port of the GT 120 card. Both are currently being driven at 60Hz and it is killing my eyes. Is there anyway to enable the currently grayed-out 75Hz monitor refresh setting? I have disconnect one of the monitors to see if this will enable only one monitor to be driven at 75Hz but to no avail. Google searches have been unhelpful so far.
thanks in advance.

2 x quad core 2.26Ghz, 16 Gb ram, Mac OS X (10.6.2)
