Why HP High Definition? The digital entertainment revolution is in full swing. Digital cameras, digital camcorders, and CD and DVD players already rule their respective markets, empowering home consumers to easily and affordably create, manage, and enjoy high quality viewing and listening experiences. And the next big wave—already roaring towards shore and about to break—is high definition television.
The Wobulator Images without Wobulation (top) are dramatically improved by two-position Wobulation, which doubles the resolution. The technology story: HP Visual Fidelity and Wobulation Microdisplay TV and Wobulation Wobulation is a funny name for a great technology. And it’s another great example of HP ingenuity at work—leveraging our industry-leading inkjet technology into new and dazzling consumer products.
Industrial design Form, function, and style The HP HDTVs are as beautiful as the images they produce. Stylishly thin, the HP Plasma and LCD TVs complement any décor and take up less space than a traditional TV. And they’re remarkably easy to use; our intuitive onscreen menus and ergonomic remote controls turn typical setup and operation nightmares into sweet dreams.
HP MDTV: a new approach HP MDTV features DLP™ While all TVs share common characteristics, you can really see the differences in HP MDTVs in the areas of picture, sound, connectivity, styling, and ease of use. The 720p TVs—50-inch and 58-inch models—are entry-level, offering great picture quality and ease of setup.

Appendix B System Serial Number Definition 74
Appendix C DLP™ is a Texas Instruments technology through which color images are made by shining colored light onto a digital micromirror device (DMD) impregnated with small, movable mirrors. Each micromirror is responsible for an individual pixel and can oscillate several thousand times per second. The process reduces “pixelation” by increasing “active area” of the pixel.
