I have installed one but not calibrated yet (with a JVC-RS50). Beyond the information in the previous post also note that the surface of the screen is extremely glossy and per the manufacturer instructions is NOT to be touched or fingerprints will be visible and show up while viewing. They go so far as to include latex gloves in the box to use while installing. If your boardroom install will be at a height and location where people can reach out and touch the screen (ohhh wow its so SHINEY…) I would look elsewhere.
The mounting of the screen to the frame is by method of rubber O rings stretched as bungees through punch outs in the materials. It works but even though I followed instructions to the T I still had a hard time getting the screen square on the frame as the increasing tension of the bungees as you go along tends to skew the screen. I also managed to rip the screen materials in two locations, an easy fix using an ordinary office paper punch (per manufacturers recommendation)
All that said, the picture looks great!
