Hello,

Since the day I received my Gateway Vivitron or CS1572 8 years ago it
has had dim brightness (no detail in dark areas of photos). The normal
controls on the front of the monitor are maxed out.

Today I pulled the monitor cover and found two focus controls on
the left side.

There is a third Pot under the two focus controls that is "glued" into
a fixed position,

It is probably the screen/G2 control and will affect brightness.

However, there may be another master brightness control somewhere, or
it may be a menu item only accessible via special software.

It shouldn't hurt to turn up the screen/G2 pot slightly. That may be all
you need.
