Hi there .. When did you first notice this happened.. After playing a game Driver update ? .. Also are you using VGA HDMI .. Can you please post your System Information .. This will help us to help you better ... The Link below will help you to archive this
Scaling is probably not set in the driver's software properly, this happened to me on my Radeon HD 7950, scaling in the Catalyst app fixed it, for the particular monitor that was having the issue.
That's where to look OP, be it Nvidia, Catalyst or Intel for video.

Hi there ... You have not answered any questions . Or given us any Information can you please go back to my first post and answer the questions .. Also which Graphics Card are you using .. As Faladu has rightly stated this could be a scaling problem or it could be some thing else
What's your video situation, use msinfo32.exe (search box) or speccy from piriform.com or gpu-z from cpuid.com to get to the bottom of what's actually in place for your video.
It's likely scaling, did you look?
Scaling off is very easy to fix, usually a matter of moving a slider and then clicking apply | OK.
