HP and Dell Disable HEVC Support Built Into Their Laptops' CPUs

Slashdot.org - Fri, 11/21/2025 - 08:00
An anonymous reader quotes a report from Ars Technica: Some Dell and HP laptop owners have been befuddled by their machines' inability to play HEVC/H.265 content in web browsers, despite their machines' processors having integrated decoding support. Laptops with sixth-generation Intel Core and later processors have built-in hardware support for HEVC decoding and encoding. AMD has made laptop chips supporting the codec since 2015. However, both Dell and HP have disabled this feature on some of their popular business notebooks. HP discloses this in the data sheets for its affected laptops, which include the HP ProBook 460 G11 [PDF], ProBook 465 G11 [PDF], and EliteBook 665 G11 [PDF]. "Hardware acceleration for CODEC H.265/HEVC (High Efficiency Video Coding) is disabled on this platform," the note reads. Despite this notice, it can still be jarring to see a modern laptop's web browser eternally load videos that play easily in media players. HP and Dell didn't explain why the companies disabled HEVC hardware decoding on their laptops' processors. A statement from an HP spokesperson said: "In 2024, HP disabled the HEVC (H.265) codec hardware on select devices, including the 600 Series G11, 400 Series G11, and 200 Series G9 products. Customers requiring the ability to encode or decode HEVC content on one of the impacted models can utilize licensed third-party software solutions that include HEVC support. Check with your preferred video player for HEVC software support." Dell's media relations team shared a similar statement: "HEVC video playback is available on Dell's premium systems and in select standard models equipped with hardware or software, such as integrated 4K displays, discrete graphics cards, Dolby Vision, or Cyberlink BluRay software. On other standard and base systems, HEVC playback is not included, but users can access HEVC content by purchasing an affordable third-party app from the Microsoft Store. For the best experience with high-resolution content, customers are encouraged to select systems designed for 4K or high-performance needs."

CERN Can Now Produce Antihydrogen Atoms Eight Times Faster Than Before

Slashdot.org - Fri, 11/21/2025 - 05:00
fahrbot-bot shares a report from Phys.org: Physicists from Swansea University have played the leading role in a scientific breakthrough at CERN, developing an innovative technique that increases the antihydrogen trapping rate by a factor of ten. The advancement, achieved as part of the international Antihydrogen Laser Physics Apparatus (ALPHA) collaboration, has been published in Nature Communications and could help answer one of the biggest questions in physics: Why is there such a large imbalance between matter and antimatter? According to the Big Bang theory, equal amounts were created at the beginning of the universe, so why is the world around us made almost entirely of matter? Antihydrogen is the "mirror version" of hydrogen, made from an antiproton and a positron. Trapping and studying it helps scientists explore how antimatter behaves, and whether it follows the same rules as matter. Producing and trapping antihydrogen is an extremely complicated process. Previous methods took 24 hours to trap just 2,000 atoms, limiting the scope of experiments at ALPHA. The Swansea-led team has changed that. Using laser-cooled beryllium ions, the team has demonstrated that it is possible to cool positrons to less than 10 Kelvin (below -263C), significantly colder than the previous threshold of about 15 Kelvin. These cooler positrons dramatically boost the efficiency of antihydrogen production and trapping -- allowing a record 15,000 atoms to be trapped in less than seven hours.
