Distorted Screen Image

[acookson]

Hello, I recently purchased a Big Buck Hunter arcade machine for very cheap, knowing the hard drive and monitor chassis were missing. I bought a tested Wells Gardner 25" Medium Resolution monitor and a new hard drive. When I turn on the machine, I get an image shown below. I can't read any of it but it looks like it gets caught up booting and restarts over and over. This looks like the board is trying to display too large of a resolution for the screen, what do you guys think? Thanks

you'll need to flip some dip switches on the board to output a correct frequency for that monitor looks like it's outputting 15k, you'll need to set it to 25k.

The SW5-Dip switches can be found near the flashing
green LED.
Dip switch 1 (OFF): Medium Resolution (DEFAULT)
Dip switch 1 (ON): Low Resolution
**Dip switch 2 (OFF): Low Resolution B Adjust
Dip switch 2 (ON): Low Resolution A (DEFAULT)
Dip switch 3 (ON): Always "ON" (DEFAULT)
Dip switch 4 (ON): Always "ON" (DEFAULT)
**If you are experiencing a “jittery” image, try this mode to
correct. Restart the game and adjust the monitor
