Quoted from winteriscoming:
Palette choices even for 4 shades is preferable to being locked into one color. That's the big draw-back in my opinion to ColorDMD Sigma vs. SmartDMD/DMD Extender (well and price difference ).

Even being limited to 4 custom colors can lead to awesome results.

How are you driving (clocking) the panel matrix in your Twlight Zone video? Are you using the original pixel refresh signals that would normally go to a plasma display? Reason I am interested is things like the lack of screen tearing and jitter as well as the pixel modulation for the different shades looks absolutely bang-on in your video. DMD Extender has some minor issues with not updating the color palette data between frames (planes) but granted you aren't using color in this example.
