Dynamo Cabinet 19″ Monitor Mount Board Dimensions

Last Saturday I mounted a 19″ monitor in my Tetris Dynamo cabinet. The cabinet is 25.5″ wide, so I don’t think it was meant to fit a 25″ monitor originally, the monitor opening is 22.25″ x 22.25″ square. Maybe it was meant for a 21″ monitor?

Either way, the opening was way too large for me to mount my 19″ monitor without some customization. A JAMMA cabinet, they are meant to be universal cabinet for any game. Probably an easy job for most guys with power tools. But I didn’t have any, so I called in a friend.

The night before I measured out the board we were cutting, and I thought I would share those dimensions here in case someone else could use the information.

I had a 3/4″ thick piece of plywood scrap that I got for free that I worked with. I think the thicker the better since the monitor is so heavy.

Here are photos of the monitor mounted in the cabinet;

And here is the dimensions for cutting a board to fit your dynamo cabinet and mount a smaller monitor.

Notes: The holes that I drilled were 1/4″ for the mounting bolts. I made this drawing for a horizontally framed monitor. You will notice the slots to the side for the frame flaps to slide through.

The dimensions are as following (Converted to the decimal);

• Total Board Size – 22.25″ x 22.25″
• Inner Square Total Size – 14.5″ H x 18.25″ W
• Monitor Flap Slots – 1″ H x 1.0625″ W
• Space Horizontally around cutout – 1.875″
• Space Vertically around cutout – 3.875″
• Bolt Placement From The Left of Board (Top and Bottom) – 2.625″, 9″, 15.5″
• Space to center of holes – 75″

Hope I described that clearly. Like I said above, I had to make the opening a little taller than 14.5″ to fit the 19″ Electrohome monitor screws.
