Two @media variables, issue

Two @media variables, issue

I have two @media variables in my css thats cause a problem.
One is with smaller width @media only screen and (min-width: 1290px). And
the second one is with greater width @media only screen and (min-width:
1610px), allowing me to display more content.
Now, with my browser window in full screen, and a monitor resolution of
1680 x 1050 pixels, I still cannot get @media only screen and (min-width:
1610px) to appear.
Am I missing something?
Thanks.
