Q I went to Best Buy looking for a TV with the highest possible refresh rate. (I like to watch sports.)

The salesperson there explained to me that buying a 240Hz TV would be a waste of money since there are no broadcasts with that frame rate—TV networks, cable, and satellite providers all transmit either 60Hz or 120Hz signals. He also said that if a set receives a signal that doesn’t match from its native refresh rate (240 Hz, for example), it can’t convert it. Was the salesman right, or I should follow through with my initial plan to buy a 240Hz set? —Nelson Aleman

Q I’m planning a significant overhaul of my home theater and am leaning toward using the configuration suggested for Auro-3D: 10.1, with four corner speakers and one overhead voice-of-god speaker. In replacing my current AV receiver with separates, I am concerned about buying amplifiers that I can keep over the next several advances in surround sound tech/features. Here’s my question: When using height speakers, is it important that they be amplified at the same power as those near ear-level?—Quest Fanning / Brooklyn, NY

Q I just purchased a Samsung 4K UHDTV and am now ready to spring for a new AV receiver. It’s May 2015. Are there any HDCP 2.2-compatible AV receivers available yet? —Pat Balice

Q I’m considering buying a home where the builder has options for structured wiring. The markup on this option seems a little high (a few hundred dollars to go from 16-gauge to 12-gauge speaker wire, etc.). I know the best time to run wire is during the construction process, but what is the best way to accomplish it: builder, custom installer, or DIY? One major concern is that the exterior walls will have spray-foam insulation, so once that’s in, I’m thinking those walls are hands-off.—Mike Sellers / Tomball, TX

Q The head unit on my new Lexus has a USB input. This feature inspired me to purchase a 32GB flash drive and rip my CD collection using Windows Media Player. I used the WMA setting with the bitrate maxed out to 192Kbps for the first few discs I ripped, and those files played back in the car without issue. For the next batch I tried both the WMA Lossless and WAV formats. Although the files played back in Windows Media Player on my PC, they wouldn't play when I plugged the drive into the head unit’s USB port. Can you explain why? —Buck CornHauler

The difference between regular and high-definition video is something that most folks will immediately recognize when they see it. But what about high-resolution audio? Unlike HDTV, which caught on fairly quickly and enjoyed a broad base of support from program providers and hardware manufacturers, hi-res audio or HRA, (now an industry-sanctioned term) has struggled to move out of its audiophile niche since downloadable content first came online back in 2008.

Q I recently purchased a pair of Definitive Technology BP 8060 ST tower speakers with built-in subs. They are connected to my Sony STR-DH750 receiver. What would be the correct speaker setting if I used the 8060s as my front speakers (set to Large) and continued to use my Sony sub for LFE instead of the ones built into the Def Tech towers? The rest of my system consists of two Infinity rear surrounds and a center speaker, plus two Bose speakers mounted on the front wall that I use for height speakers. —Kevin Bolin / Houston, TX

THE VERDICT
Sony’s lowest-priced 4K projector to date is packed with features and delivers a bright, beautiful picture.

When I hear someone question the value of 4K, the first thought that comes to my mind is: projection. Unless your nose is pressed up to the screen, a 4K image viewed on 50-inch flat-panel TV won’t look much different from regular old 1080p. A main advantage to 4K is that you can scale your display up to a massive size without having to worry about seeing the individual pixels that form a picture. And when you’re thinking about scaling a video display up to a massive size, nothing gives you a better return on investment than projection.
