Genuine Dell Precision 7740 FHD LCD ribbon cable

This genuine Dell OEM ribbon cable connects the 17.3 inch FHD LCD panel to the motherboard in a Precision 7740 mobile workstation. It is built for the 1920 x 1080 resolution display assembly that includes the optional IR infrared web camera. The part number is 739WK and it matches the EDA70 EDP cable specification.

IR camera support integrated into the cable

The ribbon carries both the video signal for the FHD panel and the data lines required by the optional IR web camera. Without this specific cable the infrared camera function will not operate even if the camera module itself is present. It replaces a damaged or faulty original cable to restore full display and camera operation.

FHD resolution and IR camera compatibility required

This cable fits only Precision 7740 units equipped with a 1920 x 1080 LCD and the IR camera option. It will not work with lower-resolution screens or with configurations that lack the infrared camera. Verify the part number 739WK or the EDA70 designation before ordering to ensure the correct match.

Questions about this item

Will the 739WK ribbon cable need periodic replacement under normal use?

The 739WK cable is a passive component with no moving parts; it only requires replacement if the hinge area is damaged or the FHD IR camera feed fails.

What is the first limitation when the Precision 7740 lid is opened and closed repeatedly?

Repeated flexing at the hinge stresses the 17.3 inch FHD ribbon conductors; connector fatigue on the EDP interface typically appears before the cable itself degrades.

Does the 739WK cable generate extra heat or noise during all-day operation?

The 739WK carries only video and IR camera signals, so it produces no audible noise and adds negligible heat to the Precision 7740 chassis.
