PT-12 is a CEC-enabled TV/display ON/OFF controller and extended EDID processor for HDMI signals up to 4K at 60Hz (4:2:0) resolution. When PT-12 detects an HDMI cable plug, it automatically turns on the connected display and automatically shuts down the display when signal loss is detected. PT-12 is an EDID processing tool for controlling the EDID functions.
