Presentations have never been more convincing and entertaining nowadays with the use of projectors. The use of projectors and accessories for power has replaced vintage type presentations that made use of the chalkboard/whiteboard and pens, and has minimized time consumption. We use projectors and accessories for power presentations, and not only that, various purposes and needs led to more advancement. Likewise, projectors and accessories for power enable presenters to make sure that they haven’t missed out on a topic/s because everything has been saved in the computer through certain software.

There are two types of projectors: the DLP (digital light processing) and the LCD (liquid crystal display). These all refer to internal mechanisms that the projector uses for display. It’s important to know what each technology has to offer as each has unique advantages depending on the necessities of your presentations. With the features of the DLP, we should say that it’s better for home cinema and portability than the LCD. Although there have been developments in the LCD home cinema category, some models are now claiming a 10,000:1 contrast ratio. That should suffice for projectors and accessories for power presentations.

Among the accessories out in the market today is the video splitter, which duplicates your

video output, boosting its signal from one video port to multiple monitors. It can be useful for multiple presentations such as in trade shows, computer labs, large conferences, student teacher seminars, and stores. Some brands of video splitters can display images of up to eight monitors from a single unit, and on up to 32 using daisy chaining.

Some projectors may be as light as 4.8 pounds (like the ViewSonic PJ400) but packs big power into its compact package and an 800×600 resolution as well as 1,600 lumens. Advanced video features such as progressive scan and 3.2 pull down deliver smooth, crisp video performance. It also projects sharp, precise images from data applications. It can deliver dynamic multimedia presentations with multiple inputs and HDTV signal support. This projector can be excellent for professional presentations or home entertainment use.

Brands that manufacture models of projectors and accessories are Benq, Canon, Epson, Kodak, Hasselblad, Sony, Tamron, Photofles, Promaster, Olympus, Minolta, Nikon, Leica, Mamiya, Apple, Fuji, and Pentax. Most popular features of projectors and accessories for power presentations are resolutions, DLP/LCD projection system, contrast ratio, RGB color reproduction,

lamp life, lightweight, wide-angle lens and HDTV compatibility.
