Today’s Eio post is on the digital projector.

A projector, more commonly known as an image projector, is an optical device that projects images onto a surface. Digital projectors project digital images directly from a computer or other digital media device through a lens onto a surface, most commonly a projector screen. Digital projectors have replaced transparency projectors.

Things to Consider

When purchasing a projector, there are various items to consider.

  • The size of the room
  • Resolution of the projector
  • Where the picture will be projected onto
  • What type of projector you need

Eio carries several types of digital projectors to choose from. The following are a list.

Home Theater Projectors

Home theater projectors are made specifically for having a theater type atmosphere in one’s personal place of residence. One can project the video onto a larger screen to get better picture quality, and for the home-theater experience. Combined with surround sound systems and comfortable chairs, a projector with a proper video resolution will make the movie or TV watching experience feel like you are in a movie theater.

Portable Projectors

Portable projectors follow the same concepts as their normal counterparts. They are simply made to be portable, and moved from place to place. They are often made smaller, more compact, with less cords and adapters in the back. They also often come with a carrying case for projection.
