As display interfaces push beyond 18 Gbps, the limitations of legacy HDMI TMDS signaling have become structural rather than incremental. HDMI 2.2’s Fixed Rate Link (FRL) and mandatory link training are not optional enhancements, they are essential architectural changes that enable higher bandwidth, improved robustness, and scalable future evolution. This paper explains the technical fundamentals and why the industry’s long-term trajectory makes FRL and link training unavoidable.
