It displays neutral any time the revs drop below what first gear would be. It can't do reverse. But hey, you're usually not confused about being in reverse...
Keep in mind, this thing works by dividing RPM by wheel speed. It's not like you're mounting sensors on your gearbox. But as a result, it's not going to tell you what gear you are in if you're sitting still; it only works when the car is in motion.
