How does a data projector work?
i know because enter the data

There are two types of projectors: The two types of projectors are LCD and DLP. LCD: LCD stands for Liquid Crystal Display. The way this places an image on a screen is fa…scinating and not nearly as complex as you might imagine. A bulb is set up to shine a fairly powerful light through a prism. The prism splits the light into its component colors and these are sent through small LCD screens. The screens themselves are sent signals to allow just so much of the light through at specific pixel locations. The light is then beamed through a lens onto a screen where the images can be seen by the human eye. DLP: DLP, or Digital Light Processing is a bit more complex. This time the light is shined through a spinning color wheel onto a chip that is mounted with hundreds of thousands of tiny mirrors. The mirrors are turned off or on by electronic impulses according to the need for the color at that moment. Even though only one color is shown at a time, one color follows another so quickly that the primary colors seem to blend into the appropriate color. The image appears to be constantly lit, when in fact small parts of it are constantly flickering. This technology was developed by Texas Instruments and is based on an older technology that was used for color television in the 1950s.

A video projector takes a video and reflects it off a mirror. Thevideo is played on a screen that is a solid color preferably white.
It is a Output device as it projects images and text.
A data projector is both an input and output device as it takesimages and then displays them on its screen. Data projectors areused in schools and businesses.
The only real similarity that I can think of is they both project images onto a wall or projector screen.
A Data Projector (referred to as Digital Projector) is a projector that gets its image from a Digital Source, such as VGA (computer), RCA (the most common A/V input), S-Video …(another form of video input), and some others. These projectors are most commonly used along with DLP or LCD Technology. An Overhead Projector is an older style of projection, common in Education (Schools). These projectors are totally manual and require you to put a transparent image onto glass to project the image overhead.
To project the image of a computer video output onto a screen or surface.
what are the advantages of a data projector
A data projector is designed for computer projection. It typically only has VGA inputs. An LCD projector is the most common type of projector, which includes data projectors a…nd home theater projectors.
This may be difficult. If the television has video outputs, you can connect these to the projector. Most of the connections found on a tv are inputs, however.
Do you mean connect it to a projector? If so, you need a projector, your computer and a special screen cord. Connect the cord to your computer and projector and is should work…!

The earliest projector recognized as a useful data projector was the BarcoVision projector, introduced in 1981 by Barco, a Belgian company. The projector used three cathode ra…y tubes, one each for red, green and blue images. Although CRT projectors had been around for some years, the image resolution was not sufficient to be useful. The BarcoVision was used for the European launch of the IBM PC. The projector was large and heavy, weighing in at more than seventy pounds, took about one hour to line up and achieve thermal stability and was notoriously unreliable. In the US Gene Dolgoff is credited with the production of the first LCD projector in 1984. Dolgoff has a long history of image processing and display developments with the LCD projector being one of his earliest. The CRT projectors had a head start on LCD models and it took almost two decades for the LCD projectors to fully dominate the projection market.

Data projectors are devices that project computer output onto a screen or wall. They are widely used in classrooms, offices, conference rooms, and auditoriums for instruction …and presentations.
yes it can be used with projector.the projector will work as a second display.
