Correct Screen Proportions?

[onlyonemac]

The size adjustments are clearly marked on the cover over the analog board once you remove the back of the computer.

It's not a compact. It's an Apple Macintosh Colour Display (the one that sits on top of your Mac). It's got three holes at the back, but they only offer the position and parallel adjusters, no size or trapeziod. Where are those on the Apple Macintosh Colour Display?

That I don't know without looking. If the adjustments have drifted that badly though, you probably have some bad components, likely some capacitors, but other things may have drifted out of spec.
