At a Glance: Four-port HDMI switch • Inconsistent 2D-to-3D conversion • 3D conversion of video games causes lag

Believe it or not, the idea behind 3D movies started in the 1890s when William Friese-Greene filed a patent for a 3D movie process in which two films would be projected side by side on the screen and the viewers would look through a stereoscope to converge the two images. Needless to say, this didn't take off given the impractical viewing conditions. Over the next 100-plus years, 3D would attempt—and fail—to catch on with audiences.

Bob Carver is a legend in the A/V industry, and when he formed Sunfire in the 1990s, the company’s name became closely associated with subwoofers. In 1996, the Sunfire True Subwoofer, as it was marketed, was born, and it popularized what eventually became a whole new subcategory (so to speak) of the speaker industry. The 11.5-inch cube produced a copious amount of bass from a small enclosure by utilizing specially designed drive units and a patented Tracking Downconverter (TDC) amplifier that could dynamically adjust its power supply based on the incoming signals.

The SEC (Securities and Exchange Commission) requires mutual fund companies to tell investors that a fund’s past performance does not necessarily predict future results—and the same could be said of Blu-ray players. In the case of LG, I’ve had the opportunity to audition its top-of-the-line offering for each of the past four years. In 2009, the company’s BD390 (Home Theater, January 2010) was the fastest player I’d ever used, and in July 2010, I awarded its BD590 a Top Pick because of its solid Blu-ray performance and plethora of streaming services. Unfortunately, in 2011 LG dropped the ball with the BD690 (Home Theater, September 2011) with faulty firmware releases and buggy disc playback.

In late 2003, HDMI-equipped consumer-electronic devices started to appear on the market. Unfortunately, the transition to digital has been anything but smooth. Although HDMI was a vast improvement over DVI (Digital Visual Interface) in its ability to carry both audio and video in one cable, it came with its own set of issues.
