The newly released HDMI 2.2 solves a persistent annoyance for gamers and home theater users: audio-video synchronization errors. Many shoppers wonder whether they should splurge on HDMI 2.2-ready TVs, replace existing cables, or fear their current gear will become obsolete. Let’s break down the key facts.
Unveiled at CES 2025, HDMI 2.2’s certified Ultra96 cables are set for mass production in Q3 this year. Every HDMI generation—from 1.4 to today’s mainstream HDMI 2.1—removes critical display technology limitations.Ultra-High-Speed Hdmi Cable 2.2 brings two transformative upgrades: the Latency Indication Protocol (LIP) and doubled transmission bandwidth.
LIP Protocol: The Fix for Lip-Sync Issues：
High-Speed HDMI Cable 2.2’s flagship innovation, LIP (Latency Indication Protocol), addresses this flaw. It creates a unified timing network across all linked HDMI Cable devices. Every piece of equipment calculates and reports its internal processing latency in real time. The source device then computes the total end-to-end delay gap between video reaching the display and audio reaching speakers, and carries out microsecond-level automatic compensation for audio or video streams.
