Overview
Two HDMI ports and listed Ultra HD 4K support define the JTD0102/4K, a video converter from J-Tech Digital that sits between source devices and a display, converting or switching HDMI connections rather than acting as a stand-alone media device.
Video converters can mean anything from format converters to simple HDMI switchers; with two HDMI ports and 4K support listed, this unit reads as an HDMI signal converter or switcher rather than an analog-to-digital box. J-Tech Digital sells mainly to AV installers, so expect straightforward hardware over consumer packaging polish.
