Question: How do I get the screen resolution down to where I can set the screen resolution and click the apply icon? I can't get the screen resolution page to move up and down to click the icon that is under the bottom bar at the bottom of the screen to click it!

Answer: 
You can hold down alt then click-drag the window you need to move around.

Works on KDE, not sure how the other DE's will handle it though.
In my case it works to use the workspace below it. Than you can see the second half of the window. Hope it works for you aswell.

It's just a solution to press the apply button...
