Quoted from Aurich:

From their site:
"How can I change the settings on my ColorDMD display?
ColorDMD controller boards include a simple four-button menu system for changing and saving display settings. The right button is used to enter the menu system. Then left and right buttons move through the adjustable settings which currently include color, display style, backlight, and mounting position. The inner buttons are used to modify settings. The "SAVE AND EXIT" screen allows new settings to be stored to the display."
Basically get access to the back of it, and then hit the button on the right (with the screen facing you the far right button). That will get you into the menu to mess with settings.

Quoted from Aurich:

Ah, okay, so go through the menu and one of the options will let you choose between the styles, like dots, dotsXL, scan lines, tile, etc. By default it should be on dots, so look for that.

Quoted from beefzap:

So what is the summary here? Without delving into all of the posts, I am interested. But The standard Iron Man is by far the worst as far as the DMD, most of the images I don't even recognize. Can you actually see what is going on with the color DMD?
