Quick guide to buying a projector
Profile: SOHO users and freelance lecturers Type: Multi-use projectors not more than 4kg Est. Price: S$2,000 (US$1,472.50) to S$5,000 (US$3,681.26) Multi-use projectors, which are designed to handle simple presentations at work as well as DVD movie playback at home, have become an extremely popular choice among SOHO users and freelance lecturers. Reasonably priced, these projectors usually offer a good compromise of weight and features and come with user-selectable screen aspect ratios.
Shopping specs  Brightness
Depending on the type of home theater setup and presentation crowd, the brightness of multi-use projectors generally ranges from 1,000 to 2,000 lumens. In most cases, 1,500 lumens is a good bet for those looking at no more than 20 people in a relatively well-lit room. Look out for models which can scale the lumens rating to generate less noise from the projector's cooling fan. Resolution
XGA is naturally the preferred resolution choice for projectors today as it produces the best image quality from current notebooks with XGA native resolution. However, if cost is a priority, SVGA projector models may be more economical. The only tradeoff for SVGA models is the limited resolution which may affect the image quality for some computer presentations. Otherwise, there is hardly any degradation in DVD movie quality. Contrast ratio
The higher the contrast ratio, the richer the black appears on the image. If you are using your projector for video purposes, choose one with a high contrast ratio to deliver the best-quality images. DLP technology is typically found in multi-use projectors because it offers significantly higher contrast ratios (about 2000:1) than LCD (400:1). Aspect ratio
Most multi-use projectors come with two user-selectable aspect ratios: The standard 4:3 and the widescreen 16:9. This provides the flexibility to switch between the 4:3 aspect ratio for computer presentations and 16:9 display for letterbox movies. Other nice-to-have features
