dual monitor screen resolution;

I was running XP pro and my resolutions were recognized no problem, I did a clean install of Windows 7 and the resolution are not displaying properly.
Both my monitors are 1080, but what I boot the resolutions are way off and screens either don't fit the screen or are so low that the icons etc are very large and blurry.
I know how to change it, but when I go to display propreties and try the drop-down menu for resolution it's maxed out on my primary at a much lower resolution number and the secondary one has the proper 1080 option, but the picture is about a third the size of the screen.
I updated my graphics card but it didnt help.
Like I said before, it was fine with XP.
I hope this makes sense to someone and i can get some help.
Thanks you and happy holidays!
