As with any display devices, one is presented with the issue on the appropriate resolution when buying new projectors. A good rule of thumb would be to check for compatibility of the computer resolution with that of the projector resolution. Although, the scaling technology of projectors allow for the accommodation of different resolutions, the resulting image quality would be compromised. Thus, it would be a good rule to follow to match both resolutions. The most common resolution is XGA (1024 x 768).

Manufacturers clearly believe wireless has a future in projection. The reason could be that there’s been a flood of wireless local area network (LAN) solutions in the PC industry. Most wireless projectors use the WiFi standard. A wireless card compatible with your PC is required to take advantage of this technology. Due to bandwidth restrictions, wireless projectors are not yet capable of displaying full motion video without reducing frame rate making it unfit for home entertainment.

Using projectors can perhaps be a lot easier than understanding how the technology works. Projectors have been in use since 1420 (thanks to the idea of Johannes de Fontana) with the early projectors being just a lamp, some lens, and a white cloth for a screen. Although the principles applied to that projector is pretty much similar to what we have today, modern projectors have been developed to use some complex technology.

Movies are so much a part of the modern world that even with the popularity of the VHS and now the DVD, still nothing compares to watching your favorite movie on a huge screen. In the United States alone, there are more than 37,000 movie projectors and screens that clearly attest to just how people love to go the movies. Two things concern us regarding watching movies, the movie projectors and screens. Lets discuss each one separately.

The history of multimedia projectors dates back to as far as 1420. This idea came from Johannes de Fontana who envisioned in a drawing a sketch of a monk holding a lantern. In the side of a lantern was a small translucent window that had an image of a devil holding a lance. Probably drawn on a thin sheet of bone and with the help of a lens, the image was projected onto a wall by the lantern’s flame.
