Small Projector more popular now days, The Small projectors are compact and portable but have greatly in size, brightness, resolution, connectivity, and other factors. There are a lot of portable projectors on the market. If you’re thinking about getting a small projector, The following brief guide can help you choose the projector that’s right for your needs
Resolution
The resolution is simply the number of pixels projected onto the screen. Resolution is the number of pixels per square inch of the image produced. The higher the resolution, the clearer the image.
SVGA Projector Resolution = 800 X 600 pixels
SVGA is adequate for watching movies, DVDs or TV, however it may show “jaggies” when trying to show computer graphics or PowerPoint slides.
XGA Projector Resolution = 1,024 x 767 pixels
XGA has nearly become the standard for business applications. It can display data, graphics or video without any problem. Not only that, but most notebook computers have a native resolution of XGA, which means the projector will not have to down convert the data.
SXGA Projector Resolution = 1,280 x 1,024 pixels
SXGA is even better resolution. Those who need larger images and/or extra-sharp detail should consider an SXGA resolution projector.
UXGA Projector Resolution = 1,600 x 1200 pixels
UXGA provides very high resolution providing superior detail. UXGA-native resolution projectors are rare, and usually cost quite a bit more.
Brightness
While projectors with less than 1000 ANSI lumens may be sufficient for projecting black and white images in dark rooms
if you are always giving presentation in a large room because the brighter the image you project, the farther away it can be seen.
A projector must have at least a minimum of 1500 lumens to be able to project effectively in a room where plenty of light comes in as when there are no blinds or curtains
Warranty
Most projectors come with either a one year, a two year, or a three year warranty. However, these warranties usually do not cover the lamp life. Lamps usually have their own warranty of around 90 hours. If a lamp is bad, it will usually fail within that time frame. Also, be aware that with different manufacturers, there are different warranty programs.
