Q I am planning to buy two TVs, a 65-inch LG OLED and a 49-inch Samsung LCD, both of which will be wall-mounted. I also want the option to play Blu-ray discs and DVDs with both TVs. My initial plan was to buy disc players and hide them behind the wall-mounted sets, but I can’t find a player with a vertical orientation. My goal is to see nothing but the TV on the wall. The one option I’m contemplating at this point is sticking a PlayStation 3 Super Slim game console behind the TV. Do you have any other suggestions? —Steve Knot, via email

Q I’m upgrading my home theater for Dolby Atmos and have noted that various speakers are now being specifically marketed for this purpose. For example, I’ve seen compact speakers with sloped, downward-pointing baffles that are designed to be wall-mounted near the ceiling. Are these as effective in delivering overhead effects as an in-ceiling or Atmos Enabled speaker? Also, could an Atmos Enabled speaker be mounted in the same manner near the ceiling? —R. Hatton, via email

Q Can I use an HDMI 1.3b cable to connect an Ultra HD Blu-Ray player to my regular HDTV? Will the cable downscale the 4K image to 1080p, or do I need to use an HDMI 2.0 cable for it to work? —Charles Kuforiji, via email

Q I’ve got a decent Velodyne subwoofer that I’d like to connect to a powered soundbar. Most soundbar manufacturers now use wireless subwoofer connections, however, so I’m struggling to find one that’s capable of connecting with my sub. Could you recommend a mid-level or a high-end soundbar that features a hardwired subwoofer output? —Jim O’Hara, via email

Q I would like to use an Oppo BDP-93 as the Blu-ray player in my system connected to an Arcam AVR350 A/V receiver. Since the Arcam is a legacy AVR with no HDMI switching, I will need to use the Oppo’s component video output. Here’s my question: Will I be able to get high-definition resolution from Blu-ray discs with this setup? I have read that Blu-rays have embedded ICT (Image Constraint Token), which forces the player to downscale the video resolution to DVD quality. Also, are there any workarounds, like using an Oppo player with early (pre-ICT) firmware? —Lisa Kaye, via email

QWhen researching DACs, I ran across the Cambridge Audio CXN, a network audio player that upsamples all inputs to a 24-bit/384kHz hi-res format using “polynomial curve fitting interpolation.” This seems to be the only DAC that offers that kind of feature. Most Ultra HDTVs and Blu-ray players also provide upscaling, but for video. In my experience, this is a very effective feature that improves the experience of watching a regular DVD. Here’s my question: Does audio upsampling have the same effect as video upscaling? —Mike Yang / via e-mail

Q I can’t seem to get clear dialogue when playing some movies and TV shows and am forced to used closed captioning. I believe my problem is caused by improper phase. My home theater setup consists of five speakers plus dual subwoofers that have a polarity switch and phase knob. I’ve heard that the proper way to adjust phase is to play a sine wave at 80 Hz (same as my crossover setting) and then turn off all speakers except the left or right speaker and its adjacent sub. The next step: adjust polarity and phase until you measure the highest SPL level at the main listening position. Am I going about things right? Any other suggestions to improve dialogue intelligibility in my system? —AMIT ALCALAY

Q I have searched extensively for an HDMI splitter that will let me connect a high dynamic range source to both my new Dolby Vision-capable Vizio TV and my legacy Anthem receiver (for lossless audio). Oppo’s UDP-203 Ultra HD Blu-ray player has dual HDMI outputs and supports Dolby Vision. It also has an HDMI input that would enable passthrough of another HDR-capable source like a Chromecast Ultra, Roku Ultra, Fire TV, or Apple TV 4K. Here’s my question: Is there a less expensive option than the Oppo that would deliver the same result? —Andy Lutz / Houston, TX

Q Why are different units of brightness measurement used for different display technologies? For example, I’ve seen lumens used for home theater projectors, foot-lamberts for movie theaters, and nits for high dynamic range-capable TVs. Wouldn’t it be less confusing for the average consumer to lump everything together as a single measurement?

Q I’m currently using an Apple TV 4K box that’s connected to my HDTV with an HDMI cable. For sound, I run a cable from the HDTV’s optical digital output to an external DAC connected to my stereo system. Here’s my question: Would it be a useful upgrade to buy an HDMI audio converter so I could connect to my stereo system directly without first routing the signal through the TV? —Kristóf Kollár

Q I recently bought an Xbox One X console and have it connected to my Yamaha RX-A2050 AV receiver. When I watch Atmos demo videos using the Dolby Access app on the Xbox, my AVR’s front-panel LED display reads “Dolby Atmos.” I get the same result when I watch Netflix shows with an Atmos soundtrack. When viewing Ultra HD Blu-rays with Dolby Atmos soundtracks, however, the receiver’s front panel will read “Dolby TrueHD.” Are Atmos and TrueHD the same thing? —Hans Furey / via e-mail

Q I want to install a Dolby Atmos 5.1.2 speaker configuration using ceiling speakers for both overhead height effects and the left/right surrounds. How would you recommend I go about positioning the speakers? —Tuck Seng

Q My home theater system is based around a Sony VPL-VW675ES projector and a 2.4:1 aspect ratio screen. (I really like ultra-wide Cinemascope images.) Outside of reading the excellent disc reviews in Sound & Vision, is there a way to determine a film’s aspect ratio before buying it on Ultra HD Blu-ray? — Rod McClaskey

Q My system consists of a Sony XBR-X900E TV, a PlayStation 4Pro console, and a Yamaha YAS-207 soundbar. The PS4 Pro does not play Ultra HD Blu-ray Discs, so I’m planning to buy an Ultra HD Blu-ray player. Here’s my problem: I want to connect both the PS4 Pro and the disc player to the Yamaha, but the soundbar only has one HDMI input. I’ve looked around for an HDMI switcher that’s compatible with both 4K/60-Hz video signals and high dynamic range but haven’t been able to find one. Will I have to switch the cable connected to the soundbar from my sources on an as-needed basis to maintain best picture and sound quality? —Paul Trava / via e-mail

Q I recently bought an Epson Home Cinema 3700 LCD projector after reading a review of it in Sound & Vision. The projector remains boxed up as I decide on a screen to install in my light-controlled basement. While I plan to watch regular 2D content with the projector, my main interest is viewing my Blu-ray 3D movie collection, which I continue to add to as new titles become available.  

I understand from reading your magazine that active 3D glasses considerably reduce image brightness. Another Sound & Vision review of Da-Lite’s 2.8 gain High Power screen , led me to believe it would be a perfect screen option, but Da-Lite has discontinued that model. As an alternative, Da-Lite recommends its HD Progressive screen, which has a gain of 1.3. Will the HD Progressive provide a bright enough image for 3D viewing? I feel that I should look for a higher gain screen, but don’t want to spend more than $2,000. —Mitchell Ulrich
