Originally, the stock monitor was the 25 inch Wells Gardner U5000.
Due to all the problems this monitor had right out of the box, the monitor was
replaced with 25 inch Wells Gardner 7500 (wgm2575-u4gs27ZJ)
NFL Blitz was the first production game to come standard with the U5000, and it didnt go well as I understand it.
I read stories in the Star Tech Journal about some guy in Florida who received his new NFL Blitz and the was sent 3 monitors just to keep it working in the first six months before they could find a fix for its problems.
