Do you have some setting on your actual monitor-hardware you can tweak? You know how most lcd-monitors have auto-settings enabled. Maybe something there is ducking with your x-configs? FWIW, I've seen problems when I've had lcd-monitors connected over a kvm-switch and/or monitor-cable extenders. Sometimes the OS just can't correctly identify the monitor and the only way to fix it is to connect the montor directly to the computer at least once to properly identify it. Also, do you have a way to connect the monitor to a computer running eg Windows, just to see it's CentOS and Gnome that's giving you grief and not the hardware?
