The Dell RNMK1 EDP cable connects a compatible laptop to a non-touch LCD display assembly. It is intended for systems configured with an optional infrared camera, combining the display ribbon cable role with support for the IR camera connection.
Dell lists the Latitude 5440, Latitude 5450, Precision 3480 and Precision 3490 as compatible systems. The RNMK1 is specifically for non-touchscreen displays, so its defined use is in a non-touch configuration with an IR camera.
Use this replacement display cable when servicing the display connection in one of these supported laptop configurations. Its exact part reference is RNMK1; Dell’s corresponding part number is CPA-RNMK1.
