A digital projector is really a device that connects to a computer or like devise via cabling to enable the computer monitor display to be enlarged and projected onto a screen. The standard digital projector connects via a VGA lead direct to your computer or uses component video cables, (red, green and blue plugs) to connect to your DVD player, HDTV, set top box or video camera. Even so to be safe usually make certain to double check the projector has the right outputs to connect to the devise or devises you wish to connect it to. Features of a top quality digital projector need to contain:
Digital Projectors - Resolution
Digital projector resolution refers to the pixel density of the image to be projected. A digital projector has two resolutions, the natural resolution and maximum resolution. The natural resolution is the standard pixel size of the projected image; the maximum resolution is the maximum capability of the projector. Generally a digital projector needs to be able to accept resolutions of 800x600, 1024x768 or 1280x1024, even so it is not the size of the resolution the digital projector can accept which is important, but rather the native resolution of the projector. The higher the native resolution of the projector the greater the colour high quality, or really should I say color density of the projected image.
Digital Projectors - Lumens
Lumens refer to the brightness of the projected image. Simply put the higher the lumens the brighter the projection. Brightness ratings, measured in lumens, are typically lower for property theatre models than for office models. Room size and screen size/distance will also affect the want for much more or less lumens. A projector could have a excellent Lumens rating, but if the contrast ratio is low, you image will look washed out. For low-ambient or true lights-out productions, you may locate that a 1000 to 1500 lumens rating is sufficient. In case you need a extremely bright projector (3000 lumens or a lot more), an LCD projector is most likely your best option. The lowest lumen projectors right now start at about 700 lumens and go up to a jaw-dropping 15,000 lumens. A great rule of thumb is that it's often better to err on the side of too several lumens than too few.
Digital Projectors - Throw Distance
Throw distance refers to the maximum distance your digital projector may be positioned away from the screen just before image resolution, luminosity and consequently image quality are affected. The greater the throw distance, the larger the size of the projected image on the screen. Digital projector throw distance is an critical key feature if you are planning to use the projector in a big room or outdoor environment, however for the home user todays fundamental digital projector has more than sufficient throw distance to meet the requirements of your residence movie theatre.
Digital Projectors - Aspect Ratio
Aspect ratio refers to the ratio between the width and height of the projected image. You can find 3 standard aspect ratios settings that you should ensure your digital projector projects these are: 1:1, 4:three and 16:9. Having a digital projector which has aspect ratio options are crucial as different media are delivered in distinct aspect ratios. For instance standard video is delivered with an aspect ratio of (4:3), although HDTV uses a (16:9) format. If your digital projector had a locked aspect ratio of (4:3) you would not be able to experience in full, the visual experience of wide screen movies or images. With more and more digital media such as cable and on the internet TV networks adopting the (16:9) format this is some thing to definitely check.
Display Features - fixed keystone correction and lens shift functions
To make certain it is possible to maximize the high quality of the digitally projected image on your presentation screen make certain that the digital projector has fixed keystone correction along with a lens shift function. Fixed keystone correction shoots the image higher than the lens so the projector itself does not block the viewers line of sight. Similarly the lens shift function enables you to shift the image up and down and left and right. A handy tool for making fine-tuning the position of your projected image on the screen.
