I have a mac pro with dual monitors. ATI x1900 card.
I can't change the refresh rate in display prefs. It is seta @ 60 hz.
Yet, I read on an ATI forum that when using dvi to vga adapter, you can go up to 85 hz.

Sometimes my eyes bother me and I wonder if it is because refresh rate is too slow.
Should I reconnect my screens using adapters to get higher refresh rates?

I assume DVI is so much better than VGA, but I'm not a pro graphics user so I don't know.

What do you think?
