Flagship Home Theater - Part 1: Anthem LTX-500 LCoS Projector and SI Black Diamond II Screen

The SI Screens Black Diamond II Projection Screen

The physical design of the Black Diamond is similar to other fixed-frame screens.  The main difference is the unique and innovative material used for the projection surface.  Although many buyers of this product will have it installed professionally, it well within the realm of the do-it-yourselfer to hang this screen.  Clear instructions are provided along with the necessary Allen wrench and even a pair of latex gloves for handling the screen material.  No other tools are required.

Most fixed-frame screens have material that snaps to the frame but the Black Diamond works a bit differently.  The material is a semi-rigid plastic sheet with holes punched around the edges.  It is then held in the frame with heavy-duty rubber bands looped over studs you install before assembly.  SI provides a handy tube tool to help you stretch the rubber bands over the studs.

The frame assembles easily (after installation of the studs) with four pieces of angle iron.  Simply slide the pieces together and tighten the set screws with the Allen wrench.  Then it’s only a matter of carefully unrolling the material and attaching it to the studs with the rubber bands.  Once the screen is on the wall, you finish by removing the protective plastic layer from the material.

The hanging system is common to fixed-frame products with a tongue-in-groove setup.  I was fortunate that my Carada wall bracket fit the groove in the SI frame perfectly.  Once I shimmed the bottom of the screen to make it perfectly vertical, I was ready to watch some movies!
