Den der er ikke passiv. Den forsynes nok av 5V og trekker 250mA gjennom HDMI porten, noe som ikke er helt vanlig at en HDMI port klarer å levere. Et digitalt signal kan helt umulig konverteres til et analogt uten en krets som trenger strøm. Det er enkel fysikk.
I tilfeller hvor dette fungerer er det noe som ikke følger standardene:
Litt fra Wiki:
"HDMI can only be used with older analog-only devices (using connections such as SCART, VGA, RCA, etc.) by means of a digital-to-analog converter or AV receiver, as the interface does not carry any analog signals (unlike DVI, where devices with DVI-I ports accept or provide either digital or analog signals). Cables are available that contain the necessary electronics, but it is important to distinguish these active converter cables from passive HDMI to VGA cables (which are typically cheaper as they don't include any electronics). The passive cables are only useful if you have a device that is generating or expecting HDMI signals on a VGA connector, or VGA signals on an HDMI connector; this is a non-standard feature, not implemented by most devices."
