At SID 2011, LG Display had an interesting demo in its bootha series of flat panels of different sizes and resolutions to show how these two parameters are related. To maintain a given amount of detail as the screen size increases, so must the resolution, even as the number of pixels per inch decreases. The two largest screens have 4K resolution, while the two smallest are 720p (roughly 1K). I was unable to find out why they had such different color profiles.
In addition to the SL90, LG also introduced the SL80 line of LCD TVs, which use conventional fluorescent backlighting. Even so, their depth is a svelte 1.8 inches, and they also incorporate a "single layer" design with a single piece of glass covering both screen and narrow bezel. Three screen sizes comprise this line—42, 47, and 55 inches. The SL80 is available now for retail prices of $1600, $1900, and $2800, respectively.
At LG's press conference, we got our first look at the new SL90 series of LCD TVs, which sport LED edge lighting. This precludes local dimming but allows a super-slim profile of only 1.15 inches. Also of note is LG's "single layer" design, in which a single piece of glass covers both the screen and narrow bezel. Two screen sizes will be available later this Fall—42 inches ($2100) and 47 inches ($2400).
As with most of the major TV manufacturers, LG announced big improvements in its Smart TV functionality, which is available in 60 percent of its 2012 lineup, including the LM8600 series shown here. In addition to content from providers such as Netflix, Hulu Plus, Vudu, and many others, LG offers 3D Zone, which streams 3D content and almost 1200 apps from the LG App Store. Also new this year is a full web browser with Flash and HTML 5, allowing you to access just about anything you can find online.
LG's super-slim prototype caused a stir at the company's press conference. Even with LED backlighting and local dimming (with 240 dimming zones, over twice as many as most such sets), this panel measures only 6.9mm thick—that's about a quarter of an inch! This thing doesn't even have a model designation yet, so don't expect it in stores any time soon, but it sure is cool.
With the rise of digital-audio servers, the role of digital-to-analog converters (DACs) is becoming ever more important. Those who want the very best DAC might do well to consider the DaVinci from Light Harmonic.
Lightning Strikes Again I live in the Southeast where lightning is a serious problem. I was recently advised by an electrical contractor to have a whole-house surge protector installed. I am inclined to do this. However, I first wanted to find out if this would have a negative effect on my audio system.
Network music servers perform several distinct functionsacquiring and storing digital-audio files, managing and selecting what you want to listen to, streaming those files over a wired and/or wireless network, and receiving those files so the music can be played on a sound system. Most music-server products provide all these functions in an integrated system, but Scottish high-end long-timer Linn has taken a different approach. It's Digital Stream players, including the flagship Klimax DS, are strictly client devices that receive audio streams from the network and play them on any sound system.
