The battle of flat-screen technology is heating up, and LCD makers are fighting each other for technological superiority. As we reach the end of 2006, the production of 40-to-42-inch LCDs has grown, while pricing has reached parity with plasma displays in this size range. The list of competitive makers of LCDs in this size is exploding, creating a race to innovate. Enter Philips' latest flat panel, the 42PF9831D. This top-of-the-line LCD has a number of industry firsts, including Philips' own Aptura backlight. Aptura is designed to sharpen fast-moving images, solving one of LCD's common shortcomings. The 42PF9831D is a 1,366-by-768 high-definition display with Ambilight Full Surround technology, Philips' exclusive four-sided screen lighting system (more on this later). It also features Clear LCD signal processing—which works with the Aptura backlight for faster response time—CableCARD, a memory-card reader, and Pixel Plus 3 upconversion.

A new prerecorded video format is big news. It doesn’t come along every day. It’s been nine years since DVD was release, and it was 19 before that since LaserDisc. Enter HD DVD. Its higher transfer rate (35.5 mbps versus broadcast’s 19.4 mbps maximum) and advanced codecs (VC-1 and H.264) create a potential for audio and video quality to far exceeds broadcast HD, as well as containing a host of new features and capabilities. The first two models are the HD-A1 ($499) and HD-XA1 ($799). Both have the same performance; the step-up HD-XA model adds a better enclosure, a motorized door, RS-232, and a backlit remote.
