Genuine OEM ribbon cable for Alienware m15

This genuine Dell OEM part replaces the 15.6 inch LCD ribbon cable in an Alienware m15 laptop. It carries the video signal between the motherboard and the FHD 144Hz panel. The component matches Dell part number 7RNFT and is supplied new.

Fits Alienware m15 with FHD 144Hz display only

The cable is built for Alienware m15 models equipped with the 15.6 inch FHD 144Hz screen option. It will not work on the same chassis if it uses a different resolution, refresh rate or panel type. Buyers who need a cable for another display specification must source the correct part number.

Dell part number 7RNFT confirms fit

The single specification that decides compatibility is the Dell part number 7RNFT printed on the original ribbon. Match this number exactly before ordering because the Alienware m15 uses different cables for each LCD option.

Questions about this item

Does the 15.6-inch FHD 144Hz ribbon cable fit inside the Alienware m15 display assembly?

Yes, the DDX1T cable is built for the 15.6-inch FHD 144Hz panel and routes through the hinge area of the Alienware m15 chassis.

What is the tricky step when installing the DDX1T EDP cable in the Alienware m15?

The cable must be folded flat and seated in the hinge channel before the bezel clips down; pinching it causes signal loss.

When should the 15.6-inch FHD 144Hz LCD ribbon cable be replaced in the Alienware m15?

Replace it if the screen flickers, shows artefacts or loses the 144Hz signal after hinge movement or a drop.
