LCD (Liquid Crystal Display) projectors are devices used for displaying presentations or videos in an enlarged size. They are the modern replacements for slide projectors and overhead projects which were popular earlier.
LCD projectors are available in several variants with differing specifications. Choosing the right projector is as simple as knowing what it will be used for. The two parameters needed to compare an LCD projector are - cost and specifications. Knowing what is needed and how much you will need to use the various features / specifications of an LCD projector are going to be will help one compare the projectors with a better perspective. For this reason, it is important to know the basics of projectors before comparing them.
Aspect Ratio: It refers to the width vs. the height of the projected image. UXGA, VGA, XGA, and SVGA resolution all have a 4:3 aspect ratio.
Brightness: A projector's brightness is measured in lumens. The more light in the room where the projector will be used, the more bright the projector should be.
Contrast Ratio: Is the ratio between the darkest and brightest areas of the projected image. Medium Contrast ratio projectors can be found with a ratio of 500:1 to 1200:1.
Data Signal Ports: These ports on the projector should be compatible with whatever image source they will be paired with.
Keystone Correction: This is the ability to correct the image distortion that is created when a The projector is something other than a 90 degree angle to the screen instead.
Native resolution: The resolution of a digital projector is the actual number of physical pixels on the chip image projector.
Projection screens: These screens of various sizes and materials. Although it is possible to project images onto a white wall, the best image quality will be achieved by projecting images on a good screen.
Video Features Format: A format digital video projectorAbility to determine which video format the data that they can accept. Most projectors are all three: PAL, NTSC and SECAM.
A wide range of projectors required for precise data on the site are different on the Internet. Once these basic properties of the projectors can be compared and identified the most appropriate LCD projector, you can go and compare the prices of the projector required.
