ok I think I found the problem with the dark monitor issue. I bought a new hanns-g 28" monitor 2 weeks ago and been using it this whole time. I have the brightness turned somewhat high on this monitor and that is why my other monitors look dark. their brightness does not go up that high as the hanns-g does. So I will have to calibrate the monitors together and try to get the same level of brightness/contrast for each monitor.

now the scaling issue, this is a Wow problem. if I set windowed mode without maximize, the text looks fine on the second monitor and the first. but if I click on maximize windows mode, the text looks distorted. So i will have to check tech support at the Wow forums for a solution or a setting I might have missed.
unless someone here can help me

thanks for the help everyone
