  Digital micromirror devices have gained popularity in wavefront shaping,
offering a high frame rate alternative to liquid crystal spatial light
modulators. They are relatively inexpensive, offer high resolution, are easy to
operate, and a single device can be used in a broad optical bandwidth. However,
some technical drawbacks must be considered to achieve optimal performance.
These issues, often undocumented by manufacturers, mostly stem from the
device's original design for video projection applications. Herein, we present
a guide to characterize and mitigate these effects. Our focus is on providing
simple and practical solutions that can be easily incorporated into a typical
wavefront shaping setup.
