LG's new OLED TVs will get an audio upgrade to please home theater lovers

LG has announced that its new 2023 TVs will offer native support for DTS audio codecs for the first time, including the Dolby Atmos rival DTS:X.

Xperi, the company behind DTS:X, revealed in a press release that LG’s latest OLED and premium LCD TVs would incorporate its audio codec. Later, LG Korea reportedly confirmed to FlatPanelsHD that all of its 2023 OLED TVs (including the LG C3 and LG G3) and the “QNED85 and up” will be able to decode the DTS, DTS:X, and IMAX Enhanced audio codecs. However, LG added that its TV speakers won’t be able to play back DTS:X enhanced audio, instead, they’ll just be able to send the data to an external sound system that can.

Xperi’s DTS and DTS:X codecs are used by many Blu-ray discs and the IMAX-enhanced Marvel films on Disney Plus, so by supporting this codec LG’s 2023 OLED TVs just got a nice upgrade to their audio over their predecessors (and many rivals) if you have a library of discs (as many hardcore home theater fans do). Sure, you need one of the best soundbars or an AV receiver to actually hear the difference, but this limitation is not unexpected – the vast majority of TVs don’t boast speaker setups that can properly use immersive audio codecs like DTS:X and Dolby Atmos. 

What is DTS:X? 

DTS:X shares a lot of similarities with an alternative audio codec: Dolby Atmos. Just like Atmos, DTS:X aims to create a realistic, multi-dimensional soundstage where sound moves around you to make what you’re watching feel more real. For example, if a helicopter flies overhead in the film you’re watching, DTS:X and the right speaker system should make it sound as if it is really flying over your head.

Like Dolby Atmos, it's object-based in 3D space, rather than channel-based. Which means you don't need to have a specific kind of setup for it to work – it should be able to take advantage of soundbars with three speaker channels, or with 15.

But there are a few differences, such as the fact that DTS:X supports higher bitrates – read: on paper, it has better audio quality – though Dolby claims Atmos is more efficient with its bitrate use, resulting in comparable sound quality from both.

But the main thing is that not all content will support both DTS:X and Dolby Atmos. Many Blu-rays and 4K Blu-rays will favor DTS:X, while many of the best streaming services like Netflix and Amazon Prime Video only use Dolby Atmos. Disney Plus is one of the fewer streamers bucking the trend by announcing that IMAX Enhanced versions of its Marvel films will use DTS sound.

With LG’s 2023 TVs boasting DTS:X support and maintaining support for Dolby Atmos, these screens will offer users the versatility to enjoy content from a variety of sources – be it streamed or from a disc – at the highest possible quality.

Just remember that a TV saying that it supports DTS:X and Dolby Atmos doesn’t mean that its in-built speakers will necessarily be capable of outputting sound using these codecs. As is the case with LG screens, it simply has the ability to transfer Dolby Atmos and DTS:X data to a sound system or soundbar that can actually put them to use – our guide to the best Dolby Atmos soundbars is a great place to start, as long as you check for those that have DTS support too. (LG, Samsung and Sony usually include this; Sonos not so much.)

Windows Copilot leak suggests deeper assimilation with Windows 11 features

Key Windows 11 features may soon be customizable as Microsoft further integrates its Windows Copilot AI assistant into the operating system. This tidbit comes from tech news site Windows Latest , which claims to have discovered new .json (JavaScript Object Notation) files within recent preview builds of Windows 11. These files apparently hint at future upgrades for the desktop AI assistant. For example, a “TaskManagerService-ai-plugin.json” was found which is supposedly a “plugin for Task Manager integration”. If this ever comes out, it could give users the ability to “monitor or close running apps using” Copilot. In total, six are currently tested and they affect various aspects of Windows 11. Next, there is an “AccessbilityTools-ai-plugin.json” that gives Copilot a way to “control accessibility [tools]. This would make it "easier for those with [a] disability to navigate through the system.” Third is “ai-plugin-WindowsSettings.json” for controlling important Windows 11 set...

Google Chrome releases security fix for this major flaw, so update now

Google says it has fixed a high-severity flaw in its Chrome browser which is currently being exploited by threat actors in the wild.  In a security advisory , the company described the flaw being abused and urged the users to apply the fix immediately.  "Google is aware that an exploit for CVE-2023-2033 exists in the wild," the advisory reads. Automatic updates The zero-day in question is a confusion weakness vulnerability in the Chrome V8 JavaScript engine, the company said. Usually, this type of flaw can be used to crash the browser, but in this case it can also be used to run arbitrary code on compromised endpoints.  The flaw was discovered by Clement Lecigne from the Google Threat Analysis Group (TAG). Usually, TAG works on finding flaws abused by nation-states, or state-sponsored threat actors. There is no word on who the threat actors abusing this flaw are, though.

Samsung's ViewFinity S9 may be the monitor creatives have been searching for

Originally revealed during CES 2023 , Samsung has finally launched its ViewFinity S9 5K monitor after nine long months of waiting.  According to the announcement, the ViewFinity S9 is the company’s first-ever 5K resolution (5,120 x 2880 pixels) IPS display aimed primarily at creatives. IPS stands for in-plane switching , a form of LED tech offering some of the best color output and viewing angles on the market. This quality is highlighted by the fact that the 27-inch screen supports 99 percent of the DCI-P3 color gamut plus delivers 600 nits of brightness.  Altogether, these deliver great picture quality made vibrant by saturated colors and dark shadows. The cherry on top for the ViewFinity S9 is a Matte Display coating to “drastically [reduce] light reflections.”  As a direct rival to the Apple Studio Display , the monitor is an alternative for creative professionals looking for options. It appears Samsung has done its homework as the ViewFinity S9 addresses some of...
