Q I have a 7.1-channel in-ceiling speaker system in my home theater. How can I adapt this for a Dolby Atmos configuration? My plan is to add a standard 5.1 channel speaker system and use the in-ceiling speakers for the height effects.—Paul Wright

Q Can I use a soundbar like the Yamaha YSP-5600 as a center channel in a traditional 5.1/7.1 or Atmos setup? Would it sound better than a standard center-channel speaker? Also, does it have to be set up on its own first or last to blend in with the rest of the system? —Oliver Johnson / via e-mail

Q I’m ready to upgrade my surround sound system to a 5.1.4 Dolby Atmos configuration. My current 5.1 system uses GoldenEar Technology speakers, which I want to keep. Here’s my problem: I have no way to run wires through the ceiling to mount in-ceiling speakers, and I don’t want to deal with the unsightly wires that an on-ceiling speaker installation would require. Here’s my question: Are there any wireless speakers I could use for my Atmos upgrade? —Michael Henn

Q The Rec. 2020 color gamut is the future of TV—the standard was set years ago and has been included in the specification for Ultra HD Blu-ray. Even so, UHDTVs have been around for a few years yet none can display the Rec. 2020 color gamut. Why? Are we one day going to see Rec. 2020-capable LCD and OLED TVs, or is it true that only laser projectors are capable of reproducing that gamut? —Karim Genio / Algeria, North Africa

Q I just purchased a Samsung Ultra HDTV and plan to buy an Ultra HD Blu-ray player. My current AV receiver is four years old. Is there any way I can get a 4K picture and Dolby TrueHD/DTS-HD Master Audio sound without having to buy a new receiver? —Michael Errico / via email

Q I would like to know if my current Vizio TV (P502Ui-B1E) and Pioneer receiver (VSX-1130-K) will be able to support both the HDR10 and Dolby Vision HDR formats.  I’d really prefer not to have to upgrade the Pioneer receiver since it was purchased recently to support both 4K@60Hz video and Dolby Atmos audio in my system. I'm also interested in picking up LG’s 65EF9500 OLED, a 2015 model,  but am wondering the same thing about HDR support on that TV.  —Johnston Cheng

Q I have my Pioneer Elite SC-LX901 AV receiver connected to a 7.1 speaker system. When I press the SURR button on the remote, the receiver’s front-panel display shows all 7.1 speakers lit up and ready for action, but no sound comes out of the two Surround Back speakers. Do you have to watch a disc with a 7.1-channel soundtrack to get 7.1-channel sound, or can my receiver upscale a 5.1 soundtrack to a 7.1 format? The SC-LX901 is a Dolby Atmos-capable receiver, so I’d expect it to upscale 5.1 soundtracks for 7.1 output.—B. Hinson

Q How can I tell if a TV has a 10-bit panel to process the full 10-bit color of high dynamic range (HDR) video?  I’ve heard that certain TVs accept 10-bit signals, but display them at 8-bit resolution. I’m interested in buying Samsung’s 2016 KS9810 SUHD TV, a top-of-the-line model from 2016, but want to make sure it has 10-bit display. How will I be able to tell the difference?—Jerry Peterson

Q I bought my Samsung UN65JS9500 Ultra HDTV back in 2015.  According to Samsung, it supports high dynamic range. However, when I browse the Netflix app on the TV, the listings will indicate if a program is 4K/Ultra HD, but not if it’s high dynamic range. I’ve asked both Samsung and Netflix tech support what the problem is, but have yet to receive a clear answer. Can you help? — Jon Fraser

Q I’ve heard that sealed subwoofers sound better than ported ones with music, but that ported subs handle LFE in movie soundtracks better. I want a sub that will sound good in my large, open living room with both music and movies. Do people only use sealed subs in smaller rooms? How will a ported model sound different when playing music?—Matt Carlton
