Q My current setup includes an “older” 7.1-channel receiver that isn’t equipped to decode new sound formats such as Dolby Atmos. I understand that when you play an Atmos disc, older receivers are presented with a standard 5.1- or 7.1-channel version of the soundtrack for decoding. What difference, if any, is there between this default version and something like a Dolby True HD mix? My assumption is that it would be better to select a dedicated lossless mix over a backward-compatible, and presumably compressed, fallback mix. — Jason Acosta

A I own a Panasonic plasma TV and a Denon AV receiver. When I connect my sources directly to the TV, the picture looks great. But when I run my Oppo BDP-105 Blu-ray player, cable TV box, and Amazon Fire TV media player through the Denon using HDMI cables, the picture quality degrades. Is there a way I can work around the picture quality problems caused by my AVR? I want to continue using the AVR for audio switching and prefer to not have to connect sources directly to the TV. —Henry Yeboah / via e-mail

A Are there any home video releases with 7.1.4-channel sound? I find that most movies have 5.1-channel soundtracks? —J. Kevin Sexton / via e-mail

Q I just bought the new Apple TV 4K streaming box and am wondering how to get the best picture and sound from it. My system consists of an LG OLED Ultra HDTV and a Marantz SR7010 receiver. Should I route the signal from the box through my Marantz receiver via HDMI, or connect it directly to the TV? —Mike Franchek

A I would connect the Apple TV 4K directly to your TV — for now. Here’s why.

A Does the metadata used to enhance video for high dynamic range TVs also work with still photographs? —George Yeoh / via e-mail

Q I am trying to find a TV with low light intensity since my eyes are extremely sensitive to light. I have been told that an LCD TV with a full array LED backlight will let me dim the screen’s intensity without compromising picture quality. Is this true? If so, how does that work? —Patrick Forte

A I own an Ultra HDTV but am still using a regular Blu-ray player. I have no interest in buying Ultra HD Blu-ray Discs but would like to get the benefits of the HDR 10 and Dolby Vision High Dynamic Range (HDR) formats on my TV. Would an Ultra HD Blu-ray player apply HDR 10 and Dolby Vision HDR effects when upscaling regular Blu-rays to 4K, or are those benefits only available with Ultra HD discs? —Jason BF / via e-mail

Q I am buying an LG OLED TV that supports the Dolby Vision high dynamic range (HDR) format. Will my Denon receiver support Dolby Vision as well? What other things will I need to make Dolby Vision work? —Dave Poulson

Q I'm a big proponent of physical media and was an earlier adopter of the Ultra HD Blu-ray format. I understand that certain movies may have been shot in 4K or higher resolution (or on 35mm film, which provides enough detail to scan at 4K), but then mastered for release from a 2K digital intermediate. I’ve been able to appreciate the benefits of the Ultra HD format almost immediately thanks in large part to high dynamic range, but am bothered that some disc titles are mastered at less than Ultra HD resolution. It seems like we’ll soon be seeing "New 4K Remaster" versions of movies previously released in Ultra HD. What’s the issue here? —Jason Acosta
