A digital projector is a device that is connected to a computer or perform as via cable to the computer monitor to enable enlarged and projected onto a screen. The standard digital projector via a VGA connection lead used directly to your computer or component video cables (red, green and blue plugs) to connect your DVD player, HDTV, set-top box or video camera. However, to be sure always sure to check twice the projector has the right to develop to the outputs or a combinationShe designs to connect it. Characteristics of a high-quality digital projector should include:
Digital projector – resolution
Digital projector resolution refers are projected onto the pixel density of the image. A digital projector is equipped with two resolutions, the native resolution and maximum resolution. The native resolution is the standard pixel size of the projected image, the maximum resolution is the maximum capacity of the projector. Typically, a digital projectorbe able to be resolutions of 800×600, 1024×768 or 1280×1024, but it’s not the size of the resolution of the digital projector to accept to accept the can is important, but the native resolution of the projector. The higher the native resolution of the projector is the higher the color quality, or should I say color density of the projected image.
Digital Projectors – Lumen
Lumens refer to the brightness of the projected image. Simply put the higher the lumensthe brighter the projection. Brightness ratings, measured in lumens, are generally lower than home theater models for office models. Room size and screen size / distance will also affect the need for more or less lumens. A projector can be a major rating lumens, but if the contrast is low, you image will look washed out. In cold conditions, or true-Lights-Out Productions, you can find that one is sufficient from 1000 to 1500 lumens rating. If you have a very bright projector (3,000 lumens ormore), an LCD projector is probably the best choice. The lowest lumen projectors today start at around 700 lumens and go up to a breathtaking 15 000 lumens. A good rule of thumb is that it is always better to err the side of too many lumens than too few.
Digital Projectors – Throw Distance
Throw distance refers to the maximum distance from your digital projector is off the screen before image resolution can be positioned so brilliance and imageQuality are affected. The greater the throw distance, the greater the size of the projected image on the screen. Digital Projector throw distance is an important key feature if you plan to have to use the projector in a large room or outdoor environment, but for the home user today’s basic digital projector has more than enough to throw distance, the needs of your home movie theater . meet
Digital Projectors – Aspect Ratio
The aspect ratio is the ratio betweenthe width and height of the projected image. There are three standard aspect ratio settings that you have your digital projector projects: should ensure, 1:1, 4:3 and 16:9. With a digital projector, which has aspect ratio options are important, as are available in different media, different aspect ratios. For example, supplied with a standard video aspect ratio (4:3), is used as a HDTV (16:9) format. If your digital projector had a locked aspect ratio (4:3) would not be ablefull experience, the visual experience of wide-screen movies or pictures. With more and more digital media such as cable and online TV networks adopting the (16:9) format this is definitely something to check.
Display functions – fixed keystone correction and lens shift functions
To ensure you the quality of the digitally projected image on your screen to maximize presentation to ensure that the projector has digital keystone correction and a fixed lens shift function.Fixed Keystone Correction shoots the image higher than the lens of the projector does not block line of sight to the spectators. Likewise, the lens shift function you can move the image up and down and left and right. A handy tool for fine-tuning to make the position of your projected image on the screen.
If you are considering purchasing a digital projector to remember the key features to look for are high native resolution, high brightness and an appropriate throw for theEnvironment that you intend to use the projector
