Angles of Reflection is a series of articles written by Da-Lite which reviews the best practices for designing and specifying visual displays coupled with application basics for today's challenging system designs.

What the Holo Screen is and what it is not
Use of black in projection
Configuring the optimal projection offset
Calculating the throw distance
Factoring in Holo Screen gain
