If your job involves giving presentations in places where fixed projection facilities are not available, then your options have up to now been limited. Newer ultra-portable products such as the LP130 now offer the functionality and image quality of larger projectors in a package that weighs only 1.33kg. The catch is, you'll have to pay for this portability -- the LP130 costs a hefty AU$10,980.
The LP130 uses Digital Light Processing (DLP) technology, which is based around Texas Instruments' Digital Micromirror Device (DMD) chip. The LP130's single-chip DLP engine provides a native resolution of 1,024 by 768 pixels (1,280 by 1,024 is supported with interpolation). Because the DMD chip and its rotating colour wheel is a more space-efficient method than a three-panel LCD engine, InFocus has been able to reduce the size taken by the LP130 to 15.9cm by 21cm footprint that's significantly less than an A4 sheet of paper. Not only that, but it's a very bright product, with an impressive rating of 1,100 ANSI lumens.
Some sacrifices have been made to achieve this, and the LP130 lacks the integrated speakers of its larger siblings. However, connectivity hasn't been compromised, this product featuring a DVI-I connector for standard VGA or dedicated digital cables and a composite video port for attaching non-PC video equipment.
If your PC has a DVI-compliant graphics adapter (which are still quite rare), then you won't need to worry about the calibration issues that occur when converting analogue video signals into a digital signal. However, for VGA connections, you may find that a certain amount of fine-tuning is required on top of the automatic calibration in order to eliminate noise on some images.
