    • DisplayPort 1.2 – supports two 4K displays (4096 x 2160 30bpp @ 60 Hz)
    • Lowest latency for PCI Express audio
  • USB 3.1 (10 Gb/s) – compatible with existing USB devices and cables
  • DisplayPort 1.2 – compatible with existing DisplayPort displays, devices, and cables

Monitor 4K/UltraHD in HD

When working at 4K resolutions, Io 4K Plus outputs a high-quality HD-SDI down-converted signal on a dedicated BNC connector. This HD signal can be used to output 4K projects directly to HD recorders for broadcast and for easy viewing of 4K images on HD monitors during post-production.


HDR or High Dynamic Range provides the ability to display a wider and richer range of colours, much brighter whites, and much deeper, darker blacks than standard signals allow. This gives your imagery a more ‘dynamic’ look and allows for natural true to life colours to be communicated to your audience.

Io 4K Plus provides this support for your 4K/UltraHD/2K and HD HDR pipelines to HDMI compatible displays in software v14  with HLG and HDR 10 support with HDR Info frame metadata, in accordance with HDMI 2.0a/CTA-861.3 and HD

Analog Audio Flexibility

Embedded 16-Channel SDI and 8-Channel HDMI audio are supported as well as analogue audio inputs, outputs or both via a standard DB-25 connection.

Stereo monitoring is also possible with 2 x RCA outputs and a front panel mini-TRS headphone jack.

With desktop software v14 analogue audio can be configured for flexibility when needing to record voice-overs and more with the ability to choose how the DB-25 connection on Io 4K Plus is configured:

  • 8-Channel, 24 and 16-bit D/A analogue audio, 48 kHz sample rate, balanced, using industry standard 8x XLR on DB-25 breakout cable (cable not included)
  • Up to 8 channels can be used for input or output
  • Up to 4 channels can be used for input and output each (if input and output are enabled simultaneously)

Sync Up

Io 4K Plus can be locked to an external reference for integration into larger productions, or feed LTC in and out to ensure footage captured with Io 4K has the proper timecode.

Machine Control

An RS-422 port allows control of tape decks for frame accurate captures and layoffs.
