Changing to unlisted screen resolution on Fedora 20.

Hello.

My monitor's native resolution os 1680x1050.
Fedora core 20, doesn't list such resolution in Display Configuration utility.

So, the task is to forcibly change screen resolution to the native resolution.
Which files, and how should I edit?

Thank you, Dear experts.

Coordinated Video Timings (VESA-2003-9) is a standard by VESA which defines the timings of the component video signal. Initially intended for use by computer monitors and video cards, the standard made its way into consumer televisions.

Dear rindi, what do timings mean?

What does start, end, total mean?
