Io 4K Plus is the cutting edge of capture and output hardware available over Thunderbolt 3, offering a full set of professional video and audio connectivity with support for the latest 4K/UltraHD devices, High Frame Rate (HFR), High Dynamic Range (HDR) and deep color workflows. The power of Thunderbolt 3 enables Io 4K Plus to handle a wide range of formats from SD to HD, UltraHD and full 4K with frame rates up to 60p over both 12G-SDI and HDMI 2.0 with single cable simplicity , plus HDR 10 and HLG support over HDMI for emerging HDR workflows.

Note: High Frame Rate capabilities are dependent on host system attributes. Not all systems and configurations will support all frame rates.
*SDI connections are bidirectional. For 2K/HD, capture and monitoring can be simultaneous. For 4K/UltraHD with 12G-SDI, capture and monitoring can also be simultaneous. For 4K/UltraHD with 3G-SDI, all four connections must be used for either Input or Output. Additionally, 12G-SDI, 6G-SDI configured inputs support UltraHD / 4K only.
**Bit depth support is application dependent. Check with your software manufacturer for compatibility.
