PC Magazine: When shopping for a high definition television (HDTV), one of the common buzz words you’ll hear is resolution–but the resolution of what exactly? In the realm of HDTV, resolution can describe a video format as well as the physical number of discrete pixels a particular TV screen provides (a.k.a. screen resolution). A potentially confusing part of this description is that a HDTV’s screen resolution has nothing to do with what video formats it’s capable of displaying. All HDTVs are designed to accept a similar set of video formats (resolutions) that are automatically converted for display at the TV’s actual screen resolution. For optimal image quality, a TV’s screen and its video source should provide the same resolution. Unfortunately, this situation is rarely achieved, and it results in some degree of visual compromise. Not long ago, television manufacturers began offering sets that provide a screen resolution matching the highest video resolution available to consumers today, and that magic number is 1,080.The highest video resolution available from today’s consumer home theater gear including game consoles and HD disc players is 1080p (1,920 by 1,080 pixels progressively scanned). The most common video format for televised HD content is 1080i–the same resolution as 1080p, but the video pixels are delivered differently to save bandwidth. To be sure you’re seeing as detailed a picture as possible when viewing 1080i/p material, you need an HDTV that delivers full 1080p resolution.
