Quoted from radial_head:I've seen a few Twilight Zones that don't have a FULL color DMD but just a White/Monochrome only one instead, and I highly prefer that to a full color DMD in TZ. If you have a full color model, I would recommend AFM over TZ and spring for a White Only DMD for TZ when you get the chance.
If you contemplate going monochrome, might as well go with PIN2DMD (or DMDMK66 if you are feeling adventurous).
I had a PIN2DMD in my WhoDunnit, that I set to black and white, fitted the theme perfectly!
