So luckily, the monitor that I pulled from a weatherbeaten game works. For the most part. But I cant shrink the image. Its way too big. How do I adjust it?

width coil?

use something non-conductive

be ready for it to crumble when you try to move it also
 
First try the width coil, but if no one messed with it before it looks like you have a ceramic cap out of value. c36 maybe is the location. right by the width coil.
 
also turn down the damn blue gain a little and refocus it.. should look alot better..

proper tool is a plastic hex device that goes in there...

width coil can be CAREFULLY tirned with a allen wrench but must be done a little at a time WITH MONITOR OFF...

trust me, dont do it with it on unless you have the proper tool
