What features should I turn off before setting my Vizio TV's picture controls? What happens when you play a 7.1 Blu-ray on a 5.1 system? Can I extend an Ethernet cable by adding another cable with a female-female adaptor?

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.

I am in the market for some new gear—specifically, a new plasma and receiver. Is Home Theater planning to do a review of the Panasonic VT30 any time soon? I expect it to improve upon the VT25, but I would like to hear it from you or Tom Norton before I get it.

On the receiver front, I would like your opinion on the Denon AVR-4311CI versus AVR-4810CI. What are the differences between the two? In your opinion, do those differences or features justify the 4810CI's extra cost?

At SID 2011, LG Display had an interesting demo in its booth—a 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.
