Installed Linux, System says monitor 40", actually 32" unable to fix problem.

[AssembleThis]

I'm having a problem with the size of every thing. when i logged in, earlier today. every thing was fine. everything was the normal size and i didn't have big prints on every thing. Now i logged back in later today and i come to find out that everything on my desktop and all my other windows have gotten a lot bigger. My web browser and all its fonts are now really bigger than before. I looked into my monitor and nothing. it was the way i had left it before. but i still cant figure out what has happened. it seems like that every thing has been blown up by a lot. i remember all my quick keys for fire fox where a lot smaller and where more to the right of the screen. the folders on my desktop where smaller and weren't talking up so much space.
i just need some help on how to make every thing smaller again.
thanks

My resolution is correct. Thats not the problem. The Linux sees the monitor as a 40" Toshiba but it's a 32" Toshiba so the buttons are all way off screen. Found the icons by sliding the mouse out of screen 360 degrees and right clicking till a window popped up.
