Well the machine at our arcade is a Prex 3 or so Model. (It's burned into the screen a bit xD)
But yeah, it should have come with a remote. And during startup i think you can use it to go to the menu of the monitor and fix around the colors, warmth, sharpness, X,Y location etc.
The should also be internal ways of doing that, but i wouldn't have the slightest idea about it. ^^u |
