Quoted from Psw757:I’ve been struggling to find the optimum setting as well. Running the stock 5/5 at the moment but certain images are a little dim and some like the storage facility multiball animation are slightly washed out.
TaylorVa what are you running that sharpened the image up a bit? What is your brightness as well?
It's be nice if there was a test pattern built into the ColorDMD.
I don't doubt that they very from panel to panel a bit. But, I noticed on my Monopoly it displays a coin slot and show a coin going into it or something. What I didn't notice at first is that on the coin return button it actually says FUN on it. If you have the Contrast too high you can't see the letters. Which, I think the default setting was too high. Same with LOTR you can't see the subtle shading on the font (and the "sparkling" appears less dramatic).
At any rate, try to find an animation or text with a range of brightness/intensities and adjust from there. I'd suggest starting around 4 for contrast and see how it goes.
