According to the HDMI specification, yes it's hot-pluggable. It supports "HPD" (Hot Plug Detect Signal).The HPD (Hot-Plug-Detect) feature is a communication mechanism between a source and a sink device that makes the source device aware that it has been connected/disconnected to/from the sink device. When an HDMI cable is inserted between the two devices, the resulting hot-plug detection instantiates a start-up communication sequence.
