Avec l'USB-C, on tient enfin un connecteur universel. Finies les dérives en matière de connectique ? Pas tout à fait : au sein même de l'USB-C, tout ne se vaut pas : les câbles, chargeurs et ports peuvent s'avérer très différents entre eux.

RIP HDMI Alt Mode, we hardly knew ye

If you're using a USB-C port to connect a computer to a display, you're most likely using DisplayPort Alternate Mode (Alt Mode). Some less-intensive uses might opt for DisplayLink to connect to a dock or adapter and eventually output to a screen. But due to non-existent adoption, we can pretty much guarantee you're not using HDMI Alt Mode. And according to the HDMI Licensing Administrator (HDMI LA), you never will because the feature is dead.
NotebookCheck spoke with HDMI LA, which is responsible for licensing the HDMI Forum's HDMI specs, at CES 2023 in Las Vegas last week and learned that there won't be any certified adapters supporting HDMI Alt Mode over USB.
"According to HDMI LA, there are simply no more uses for Alt Mode," the publication reported on Wednesday. "One of the reasons is that companies like Apple have begun putting HDMI ports on their products again. HDMI Alt Mode also no longer offers any advantages. As a result, the specification will not receive any further updates."

All DisplayPort 2.0 products are now DisplayPort 2.1, VESA says

VESA released the DisplayPort 2.1 specification today. Typically when an industry group announces a new standard, it takes months or even years for products supporting the spec to be available to consumers. But DisplayPort 2.1 products are already available today; in fact, you may already own some. With a flick of its magic specs wand, VESA also declared today that any product that was already DisplayPort 2.0-certified before today's announcement is now DisplayPort 2.1-certified, too.
"VESA has been working closely with member companies to ensure that products supporting DisplayPort 2.0 would actually meet the newer, more demanding DisplayPort 2.1 spec," the announcement from VESA, which also makes DisplayHDR, AdaptiveSync/MediaSync , Clear MR , and monitor-mounting specs, said.
"Due to this effort, all previously certified DisplayPort 2.0 products including UHBR (Ultra-high Bit Rate) capable products—whether GPUs, docking station chips, monitor scalar chips, PHY repeater chips, such as re-timers, or DP40 / DP80 cables. (including both passive and active and using full-size DisplayPort, Mini DisplayPort, or USB Type-C connectors)—have already been certified to the stricter DisplayPort 2.1 spec."

AMD Ryzen 6000 gets DisplayPort 2.0-certified, product testing ramps up

Pixel and speed enthusiasts have anticipated DisplayPort 2.0 products since the Video Electronics Standards Association (VESA), which makes the spec, announced its incoming in 2019. While the pandemic inhibited the ability to test products for supporting the video protocol and slowed its release, we've inched closer to seeing monitors, PCs, and other devices earn DisplayPort 2.0 certification.
VESA on Monday announced certification for AMD's Ryzen 6000 laptop CPUs to support DisplayPort 2.0 at up to one of its highest data link rates, Ultra-high Bit Rate 10 (UHBR10), which has a 10Gbps link rate and max throughput of 40 Gbps across four lanes.
VESA introduced UHBR labels to DisplayPort 2.0 in February. Once DisplayPort 2.0 products are readily available, it'll be easier to determine which products support the higher bandwidth capabilities of the backward-compatible spec. The move came after the HDMI Licensing Administrator, which makes the HDMI spec, received backlash for not clarifying which HDMI 2.1-certified products support the max capabilities.
