Dual monitor display issue

I currently have 2 monitors (on an Asus and the other an Acer) they are both 22in monitors and have 1920x1080 display. I have been attempting to use a dual monitor sized background image but my Acer monitor isnt displaying the image as full screen like it should. The image I am using for my background is 3840x1080 so I would think it would be full screen on both monitors. I tried manually adjust the display of the monitor vertically via the monitor's internal menu but the option to move it is not selectable and acer tech-support was unable to pin-point the problem. I have attached a picture so you can see exactly what I see. (Its the left side monitor that is the issue) (Note** The black bars that are in the picture [on the bottom on the right side and on the top on left] I dont actually see on my monitors. Any suggestions would be greatly appreciated!

It only took me posting this message to finally figure out what I had done. In my Nvidea control center under "Set up Multiple displays" the two screen were not aligned perfectly resulting in my mess of a desktop. Figured it would take me admitting defeat and going to posting my own thread to finally figure out what I had done myself.
