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.įrom the last part above it seems that there are some monitors that accepts HDMI signals in the VGA port, so no conversion is needed. 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).Ĭables 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). That's highly strange because AFAIK HDMI doesn't support analog signal transmission, and indeed it's doesn't If both input / output device do not support signal conversion, a signal conversion box is required. In order for these two formats of signal to communicate with each other, both input and output devices needs to support the signal conversion function (code and decode), please kindly check with your user manual.
