HDMI 2.0 vs HDMI 1.4: What Is the Difference?

HDMI 2.0 raises the maximum bandwidth from 10.2 Gbps on HDMI 1.4 to 18 Gbps, which allows 4K video at 60 frames per second instead of 30. For video capture and AI on camera feeds, that means smoother 4K and more detail per second for the model to work with.

01

The Short Answer

Both versions use the same connector, so the difference is in the electronics at each end. A 4K source and a capture card or display must both support HDMI 2.0 to run 4K at 60 fps; if either side is HDMI 1.4, the link falls back to 4K at 30 fps or a lower resolution.

  • //
    4K at 60 fps Double the 4K frame rate of HDMI 1.4.
  • //
    More bandwidth 18 Gbps against 10.2 Gbps.
  • //
    Same connector Both ends must support HDMI 2.0 to use it.
  • //
    Better for AI More frames and detail for detection and tracking.

Why It Matters

Moving capture to HDMI 2.0 was part of the upgrade in our drone detection case study, where an SC710N1 M2 HDMI2.0 card captures 4K60 with lower latency. Our HDMI capture cards list the supported resolutions for each card.
