Picture not centered on screen - Solved

[Jmk125]

So I am wrapping up my first build, and per a separate post, I had to get a new screen because I messed up my controller board. I went with the 3.5 composite screen that is linked in wermy's guide. For some reason this new screen doesn't center the picture. It seems to be high and to the right. Does anybody know of a way to adjust the picture location so that it will be in the centered?

Is it possible that the change of screens messed with retroie? (Even though the screens are the same (with a different version of the controller board however)).

For what it is worth, I am using Helders 2.2 with a raspberry pi zero w, and the latest version of retropie.

Disregard this. I dug more and found the answer. I didn't realize that you could actually move the picture with overscan. I always thought that overscan was exclusively for the size of the screen.
