HDMI Forum’s Roadmap: No new standard until 2028; 2.2 supports 16K@60Hz for future VR/AR.
AI Integration: HDMI 2.2’s bandwidth leaves room for AI-driven upscaling (e.g., NVIDIA DLSS 5).

FAQ: Quick Answers

Q: Can HDMI 2.1 cables work with 2.2 devices?
A: Yes, but limited to 48 Gbps—you’ll lose 8K/120Hz and LIP Sync.

Q: Does HDMI 2.2 improve 4K streaming?
A: Marginally—benefits mainly 8K/VR users.

Conclusion

HDMI 2.2 is a niche upgrade for 8K/120Hz early adopters, but overkill for mainstream users. If you’re chasing cinematic immersion or competitive gaming frames, 2025 is the year to upgrade.
