Got a tech question for Sound & Vision? Email us at

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

PRICE $25,000

Crisp 4K image
Projects 120-inch picture from 10-inch distance
Can be used in average room-lighting conditions
Below-average picture uniformity
So-so contrast

Sony’s ultra-short-throw projector can dazzle for daytime viewing and fulfills its promise as a big-screen panel TV alternative, but dark-room home theater enthusiasts may be less impressed.

When it comes to setting up a home theater, the main goal should be to get the largest image that your space and budget will allow. In many cases, that’s going to mean hanging a projector from a ceiling mount at the back of the room and attaching a screen to the wall up front. Next come the light dimmers and blackout shades—both necessities if you want to get the best picture possible from your projection rig.

Sure, many high-speed HDMI cables can handle 4K/60 content. But can they hack it at that resolution for distances greater than 15 feet?
