HELP ! Screen is small? :(

Hey everyone, something happened and my screen went really small, here is a picture.



if you could help , i'm sure it's not a hard fix at all, I just can't seem to figure out what to do, thanks.

 

ctrl + increases screen size ctrl - makes it smaller

 

ctrl and roll your mousewheel up

 

hold the control key and use the scroller thing on your mouse to increase or decrease the size of the screen

 

If it's not the zoom factor then try changing your resolution/aspect ratio.
