projectors are now used by many organizations because it increases content can project onto flat surfaces. When the projectors, there are two types, namely LCD - and DLP projectors. With two, it is possible to present multimedia content to a large audience.
Comparing with each other but both projectors, LCD projectors cut better than DLP projectors. This is mainly due to the vivid colors and higher contrast image.
The various features of these projectors
Before the projector you should consider buying a few things.
The resolution - When choosing a projector you should always pay attention to the display technology. The best known here are VGA (640 x 480), UXGA (equivalent to 1,600 x 1,200) SVGA (800 x 600) and WSXGA. The resolution refers to the visible number of pixels. The higher the number of pixels, the higher the resolution.
played during the resolution and the number of colors shown a role. Currently, most projectors represent approximately 16.7 million colors. In a few cases, this number may be significantly lower.
Brightness - All projectors have a certain ANSI lumens number. The brightness of the displayed light is measured in lumens. The higher the measured in lumens brightness, the more light can cause the projector. Projectors with higher lumen number of own particularly suitable for use in brightly lit rooms. Usually, the brightness is an Projectors 1300-1500 lumens. A projector with a measured brightness of 1,400 lumens is ideal for small to medium sized rooms.
The significance of the contrast range - With the help of this factor can detect differences between light and dark. In short, the contrast ratio ensures clear images. Projectors with a mid-range located contrast range usually have a contrast ratio of 500:1 or 1,200:1 between.
Possible video formats - it can easily tell which video formats a projector accepts. Projectors usually accept these three formats, namely PAL, SECAM and NTSC.
formats - The image width and height is usually determined using the image format. Projectors typically have a 4:3 - or 16:9 aspect ratio.
keystone correction - Using this feature can be corrected on the wall or projected images. This is especially helpful when the projector is not placed in a 90-degree angle to the screen.
addition to the above factors, one should also pay attention even to the quality of cables used and the make of the canvas.
Last but not least is to be observed in the ceiling, wall outlets, etc. are nearby. Before installation you should make you of the thoughts and prepare for the installation thoroughly. While this may take some time to make, but later paid off handsomely. Even with the friends you can thus produce a WOW factor. There
