- HDMI isolator
PT-1Ci is a 4K HDR HDMI isolator for data-sensitive HDMI installations. It is an EDID buffer and storage device for HDMI signals that prevents reverse communication of the DDC signal. The device blocks HDCP and prevents EDID pass-through. The PT-1Ci lets you read and capture an EDID securely and present it to sources for compatibility with the display. The device has no effect on the audio and video streams.
