A digital projector is a device that magnifies a computer connected via cable or run as a computer monitor and can be projected onto a screen. The standard digital projector with a VGA cable connects directly to your computer or using the component video cables (red pin, green and blue) to connect the DVD player, HDTV set-top box or camcorder. But be sure to always make sure to control the projector has the right, provides a connectionwant to develop or developed to connect. It has a quality digital projector should include:
Digital projectors - Resolution
Projector resolution refers to pixel density are projected on the image. A digital projector is equipped with two resolutions, the native resolution and maximum resolution. The native resolution is the standard size of projected image pixels, the maximum resolution is the maximum capacity of the projector. Typically, a digital projectorshould be able to accept a resolution of 800x600, 1024x768 or 1280x1024, but not the size of the resolution accepting the digital projector, which can be important, but the resolution of the projector. The higher the resolution of the projector, the higher the color quality, or should I say, the color density of the projected image.
Digital Projectors - Lumen
Lumens refers to the brightness of the projected image. In short, the higher the lumens ofbrighter projection. Ratings brightness, measured in lumens, are generally lower for the models of home theater as models for the office. The size of the room and the size / distance will also affect the need for more or less lumens. A projector, a rating lumen great, but if the contrast ratio is low, faded picture. Low ambient or true lights-out production, it is possible that a sufficient assessment 1000-1500 lumens. If you have a very bright projector (3000 lumens ormore), an LCD projector is probably the best choice. The lowest lumen projectors today at about 700 lumens and go up to a stunning 15,000 lumens. A good general rule is that it is always better to err on the side of too many lumens than too little.
Digital Projectors - Projection Distance
Radius refers to the maximum distance from the screen of your digital projector can be positioned on the first image resolution, brightness, and therefore the image qualityare concerned. The greater the number of births, the greater the size of the image projected on the screen. Projector throw distance is a key feature important if you expect to use the projector in a large room or outdoors, but for home use today's basic digital projector is more than enough to throw to meet the needs of your home theater .
Digital Projectors - Aspect Ratio
Aspect ratio describes the ratio of the widthand the height of the projected image. There are three standard settings proportions that you have your digital projector projects to ensure, where: 1:1, 4:3 and 16:9. With a digital projector, the aspect ratio options are important, as various media are delivered in various formats. For example, standard video aspect ratio (4:3) delivered, while using an HDTV (16:9) format. If your digital projector has had a close ratio (4:3), would not be ableExperience in its entirety, the visual experience of big screen movies or images. With more and more digital media, such as cable television networks and online for the adoption of (16:9) format is something to check.
Display functions - Fixed keystone correction and lens shift functions
To ensure that the quality of the digital image projected on the screen to maximize your presentation so that the projector has digital keystone correction and a fixed lens shift. FestivalThe keystone correction shoots the image higher than the target for the projector itself does not block the public view. In addition, the lens shift moves the image up and down, left and right. A useful tool for the production of tuning the position of the image projected on the screen.
If you are thinking of buying a digital projector to remember the most important features to look for high native resolution, high brightness and an effective range of the environment isintention to use the projector in
