Rendering Aspect Help!

Optimus Shepard

Hello,
I know that I should know about rendering and I do. It just that ever since I got version 4.6 I keep on having to render just widescreen or for example aspect is 5:4 and I can't render the whole picture. Can someone please tell me how to remove the aspect or at least make it to render the whole thing? Thank you.
