monitor display problems

[gary <chungary sympatico ca>]

Hi,

I have installed red hat7 and when starting the gnome xwindows
environment my graphics is skewed. I am getting part of the setup but
not entirely everything. For eg. right clicking my mouse, I don't see
the menus.

This is the first time that I have installed linux at home, I have a NEC
multisync 95 monitor. It wasn't in the list of hardware when I installed
so i choose NEC multisync 90. Any ideas on how to resolve this problem?

Thanks....gary
