Apple TV 4K can use HDMI eARC to play any TV audio on your HomePod
If you have a HomePod and picked up the new Apple TV 4K, your speaker will make for a better home theater companion than it did before. As noticed by MacRumors, the latest Apple TV 4K supports the ARC (Audio Return Channel) and eARC (enhanced ARC) standards over HDMI. What this means in practice is that the Apple TV 4K can wirelessly send all audio from your television to a HomePod (or stereo pair of HomePod speakers).
LG slowly starts rolling out its 2021 OLED and LCD 4K TVs
LG's 2021 4K and 8K TVs are starting to roll out. This year the LCD includes a QNED line with Mini LED tech and the OLED TVs are getting cheaper than ever.
Vizio's new soundbar rotates its speakers for Dolby Atmos, DTS:X content
Vizio isn't just the brand that makes cheaper TVs with high-end features, over the last few years it's increasingly become known for offering a number of excellent home theater audio options too. For CES 2020 its soundbar lineup is getting a rebranding to match the popular M-Series and V-Series 4K televisions it sells, while a new premium soundbar is made to match the new OLED TVs it just announced. The Vizio Elevate Sound Bar (shown above) has 18 total drivers, with a pair of channels in the main soundbar that point forward when playing stereo or 5.1 audio, but automatically rotate up to increase height effects when they play Dolby Atmos and DTS:X encoded audio. It's made to work on its own with any TV, or to dock "seamlessly" with the Vizio OLED TVs. There's also a wireless 8-inch subwoofer and two satellite surround speakers that add p to 107dB of output. Like everything else Vizio is announcing today, there's no word on a price or release date. Other than that model, instead of simply branding its soundbars by size and speaker configuration, they now have M-Series and V-Series names just like its midrange 4K TVs (the Elevate has a P-Series model number, P514a, just like the high-end TVs). The M-Series and higher models with Atmos and DTS:X will have HDMI 2.1 inputs along with eARC support, so that you can pass through uncompressed Dolby and DTS Audio from built-in TV apps.
LG's 2019 TVs add HDMI 2.1 and 8K
CES 2019 hasn't started yet, but LG is already drip-feeding information about this year's OLED and LCD TVs. While it didn't mention the rollable OLED we're expecting, it did list model numbers for two 8K sets, with an 88-inch Z9 OLED and SM99 8K LCD TV on the way. There's no word on price yet, but the big confirmation is that thanks to HDMI 2.1 ports, all of its 2019 OLED TVs and "selected" NanoCell LCD TVs will support high frame rate (HFR) 120fps video inputs. Other features in the new standard include an enhanced audio return channel (eARC) as well as variable refresh rate (VRR) and automatic low latency mode (ALLM) to keep gamers happy. If you're snagging one of the new 8K TVs, you'll just be pleased to know you won't have to plug in four HDMI cables to get everything connected. The NanoCell name is a new brand for LG's high-end LCD TVs (SM9X and SM8X) with enhanced color, viewing angles and thin bezels. As usual, LG is also talking up its AI capabilities with Thinq technology, and a new Prime Video button on its Magic Remote that ties in directly to Amazon's Alexa routines.
