Q The 4k content I see on UHDTVs in stores looks awesome. But when I ask the salesperson to flip the feed to regular HD (from Direct TV), the picture doesn’t look nearly as good. It looks worse, in fact, than the same content shown on the standard HDTVs, and certainly worse than on my 10 year-old Sony SXRD.  My question is, if I buy a new UHDTV, how can I make the picture look as good as what I’m used to seeing on my Sony? There isn’t much 4K content yet, so what I’d mainly be watching is regular HD.—Ben Soave

Q Will I damage a stereo amplifier by using it to amplify only one channel—in this case, my system’s center speaker?—Richard Regan

Q I just signed up for Tidal music streaming and want to make sure I am getting the best sound quality from that service. My laptop is connected to my router with an Ethernet cable and then to my Onkyo pre/pro via an HDMI cable. I have the Tidal app’s settings set to HiFi.

My question is, as music streams from Tidal, does it pass through the laptop’s sound card first and then to the HDMI cable, or straight from the HDMI cable to the Onkyo pre/pro? I don’t know what sound card is equipped with the computer, and want to make sure that if streamed music does pass through, that the card isn’t detracting from the sound quality. —Andre Spits / Atlanta,GA

Q I’m planning on buying an Epson 5030UB projector. My sofa will be 14.5 feet from the screen. The room has controllable dimmers, and there will be some room light when I watch games. What screen size and type would you recommend? — Lou Gutierrez / via e-mail

Q I have owned receivers from Onkyo, Pioneer and Yamaha. With each one, the sound always seemed muddy after I used the auto-calibration function for speaker setup. In my experience, I get much better sound when setting all speaker crossovers to 200 Hz, or the highest available setting. Expert opinions I’ve read on the subject say this is wrong, though I’ve adjusted two friends’ systems in this way and they agree with me that the sound is better. Am I correct? —David Bone

Q Why can’t audio devices be daisy-chained via Bluetooth? I have a NAD Viso 1 speaker dock and a NAD 3020 integrated amp, both with Bluetooth. The units are located in different rooms. Why can’t I send the same signal from my iPhone to both units at the same time?—J. Alan Greer

Q I have a fairly large collection of CDs, all of which have been ripped to lossless WMA format. I’ve come across plenty of discussion of DACs while researching music servers, but I’m confused about why I would need one since I can already listen to digital music files, either through my computer speakers or headphones. Doesn’t that mean what I’m hearing is already in analog form? If so, what need is there to convert it to anything else? —Bill Begg / via e-mail

As I understand things, any motion on an LCD TV is accompanied by a loss in resolution. For example, 1080p isn’t really 1080p when the image is in motion. Here’s my question: Since OLED has a much faster response time than LCD, does resolution stay the same when the image contains motion? —Michael McGehee / Macon, Georgia

Q What processes what in the video chain? Say you have an Oppo Blu-ray player hooked up to a good AVR that’s hooked up to an Epson 5030 projector. Does each do its own thing? Or do you need to turn some types of processing off while leaving others enabled? Also, what is the meaning of life? —Jeff Riddick / via e-mail

Q I am in the market for a new home theater receiver and have a dilemma. My wife is hearing impaired and has trouble hearing the TV sound. We have tried a few infrared wireless headphone solutions and have been very disappointed by the poor sound quality. I am looking for a system that will allow me to hook up a separate set of headphones to run simultaneously with the TV sound. Is this possible? —John Bott / via e-mail

Q I’m curious to know if there’s any criteria for home theater component selection based on room dimensions. I want to focus my search on equipment that’s an appropriate match for my space. —Bill King / via e-mail

Q I bought a Benq W1070 projector and plan to install it in my 22-foot long by 18-foot wide by 8.5-foot high basement. The room was pre-wired by the previous owner and there’s a ceiling mount with an electric outlet close to it. The mount is about 16 feet away from the front wall. Is that too far for this projector? I was originally planning to buy a 120 inch screen, but it appears that I would need at least a 150 to 170 inch screen for that distance.—Srikanth Athipatla

Q I just moved into a new house. Because of the way my home theater room is configured, the distance between the surround sound receiver and HDTV is about 30-40 feet. How would you suggest I make this connection? What about wireless solutions? —Joe Feller
