I've used a 24" monitor and a first generation 720p 50"Samsung DLP RPTV for my air and auto sims, but I've investigated a number of other display methods. This included a 3-monitor setup. But, while the width is there, the height still seems to lack some realism. I also thought I'd like to try 3D, but the cost of 3, 3D 27" monitors could easily exceed $1500. The arrival of the less than $1000 Benq W1070 with 3D capability was just too tempting to miss. The Benq has a very short throw, compared to the FP I use for blu-ray, and so I saw a way to get a very large display. In my hobby room, I mounted the Benq on a shelf projected from a bookcase at the rear of the room and through trial and error got a 16:9 image of 48" x 87" on the opposite wall at a lens distance from the screen of 10'-6". This was with the zoom made as small as possible. Since I was going to make my screen with a standard piece of hardboard painted with Behr "Silverscreen", I was limited to a size no higher than the 48" hardboard sheet size. I wanted to minimize environmental distractions, so I put 4' wingwalls to each side of the screen on hinges so that I could adjust the angle and pulled them in to the point that they just cleared the projected image. The screen assembly is free standing and not attached to the wall, at all. I covered the top of the screen assembly with a 4' x 8' corrugated plastic political campaign sign that had been left up after the election. All were painted dark brown (wife vetoed black). It's really isolating and even though my louvered window shutters don't do a complete blackout of the room, no ambient light falls on the screen and I get a satisfactory image for sim purposes. The bottom of the screen is 26" above the floor, which corresponds to a projector shelf height of 76" above the floor. Works really well and provides the closest thing yet to VR.
