HDMI: New certifications make old HDMI app almost obsolete (www.notebookcheck.net)

The new certifications for HDMI cables are now slowly coming onto the market. Known as Gen 2, these certifications will provide verification for the authenticity of a given cable and gradually replace the first generation certifications.

This formally began in May 2023, but the HDMI Licensing Administrator (HDMI LA) has allowed the old labels to continue to be used until stocks of the corresponding cables have all been sold. In its February newsletter, cable manufacturer Club3D drew attention to this change and stated that it is currently changing its label fulfillment provider, so packs with both the old and the new certifications will soon appear in stores.

The new certification has the advantage that it can be checked more easily. According to the HDMI LA, a simple scan of the QR code on the pack is enough to verify its authenticity. The old verification, on the other hand, required the proprietary HDMI app.

I bought a fancy fiber optic certified cable to fix my TV issues since it's like a 30m run from the computer. It didn't change a single thing, turns out my 3 OG HDMI cables stringed together with two adapters and a conversion to and from mini-HDMI was fine, my TV just sucks because it's a smart TV and needs to be rebooted for HDMI inputs to work properly after a couple days.

The signal integrity requirements are vastly overblown.

Now try doing that while pushing 4k120hzHDR content. Which, I know isn’t for everyone, but it sure as hell needs that signal integrity.
