This article discusses compatibility of Elo monitors with Pot O' Gold machines.

Off-the-shelf Elo monitors will not function on a Pot O Gold machine.
Typically, monitors used on Pot O Gold machines have to be programmed by a 3rd party. These machines are usually equipped with MicroTouch 3M or old 4002 protocol touch emulation and the video typically has to be programmed as well. Elo does not offer this type of programming service. You would need to reach out to whoever programs your gaming machines.
