Quoted from RDReynolds:Stupid question - how do you get to upscaling mode? I just installed mine, kinda clueless on how to change that...
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.
