Video Projectors
Three types of technology are used in video projection. Tri-tube video projection is the oldest, but for the moment still gives the best results. It has the disadvantage of being heavy, cumbersome and a bad traveller, because the convergence adjustments during installation are quite tedious. Due to this, the tri-tube video projector should preferably be used in the case of a fixed installation. In this configuration, you obtain the best images, because this technology offers by far the warmest and most natural colours. In addition, the price of tri-rube video projectors has dropped considerably, putting them within most people’s reach. Then we find video projectors using liquid crystal technology, or LCD. They’re light, not cumbersome, and do not require convergence adjustments, making them the perfect portable solution. LCD projectors are also quite powerful, ideal for conference rooms where it’s not always easy to obtain total darkness, or for professionals who travel regularly to make commercial presentations. In addition, the way in which the pixels are disposed on a Liquid Crystal Matrix makes the presentation of computer images particularly exceptional. On the other hand, for video and cinema images, the results are not as good as with a tri-tube projector. Quite recently, we’ve seen the arrival of a promising new form of technology. Called DMD, it is more akin to LCD technology than that of tri-tube. It has the advantage of delivering an exceptional image… just as much for video as for computers. Prices remain exorbitant and improvements are still in the pipeline.
