Overview

Cyberguys!' 121 0030 is a black video converter built around three HDMI ports, with HDMI listed as its only connectivity type.

With three HDMI ports and no other listed connector types, this reads as an HDMI switch or multi-source converter rather than a box with analog inputs. High recent purchase volume suggests it fills a common need, such as routing more than one HDMI source into a single display.
