Product information

Description

The AJA Hi5-4K-Plus is an active video converter that converts professional SDI signals to HDMI 2.0 for monitoring on modern displays. It supports 4K/UltraHD resolutions up to 4096×2160 and handles multiple SDI input configurations (Quad 3G‑SDI, Quad 1.5G‑SDI or Dual 3G‑SDI) as well as single HD‑SDI to HDMI conversion.

It can generate HDR metadata compliant with HDMI v2.0a/CTA‑861.3 and supports Hybrid Log‑Gamma (HLG), ensuring accurate HDR presentation on compatible HDMI 2.0 displays. Compact, portable housing with a locking power connector and included universal power supply enables flexible placement and reliable operation in studio or field environments.

Suitable for

  • Monitoring 4K/UltraHD professional video from cameras, switchers and decks using SDI outputs
  • Integrating modern HDMI 2.0 displays into quad‑SDI 4K workflows
  • HD to HDMI conversion for HD‑SDI monitoring tasks

How to use

Connect SDI sources to the Hi5-4K-Plus inputs according to your workflow (quad or dual SDI for 4K/UltraHD, or single HD‑SDI for HD). Connect an HDMI 2.0 display to the HDMI output and apply power using the supplied universal power supply. The converter will detect input format and output the corresponding HDMI signal, handling resolution conversion, frame rate support up to 60p where applicable, HDR metadata generation, and embedded audio passthrough automatically.

Usage recommendations

For reliable HDR and HFR monitoring, use an HDMI 2.0 capable display that supports the intended 4K/UltraHD resolution and HDR format (HDR10 or HLG). Ensure SDI cabling matches the chosen input configuration (quad or dual) and verify display compatibility with 50/60p signals to guarantee correct playback.
