Genuine Dell OEM Ribbon Cable

This is a genuine Dell OEM replacement ribbon cable for the Alienware 17 R4 laptop. It carries the part number WTNR3 and matches the component originally fitted at the factory. The cable is supplied new and exactly as pictured.

For QHD screen repairs only

This cable suits owners of an Alienware 17 R4 equipped with a 17.3 inch QHD panel at 2560 x 1440 resolution. It will not work on models fitted with a Full HD or 4K display, so buyers with those screen types must look for a different part.

Direct swap inside the lid

Installation involves opening the display assembly, disconnecting the old ribbon, and routing the new cable along the same path. The delicate connectors and tight hinge area mean care is needed to avoid creasing the ribbon or damaging the socket pins.

Questions about this item

Does the WTNR3 ribbon cable fit any Alienware 17 R4 or only the QHD model?

This cable is built for the 17.3 inch QHD panel (2560 x 1440) and is listed as compatible with the Alienware 17 R4 that has that screen.

Can I reuse my existing display hinges and bezel when I swap in this cable?

The ribbon cable connects the motherboard to the LCD panel itself; hinges and bezel are separate mechanical parts and are not affected by the cable replacement.

After fitting the WTNR3 cable, how can I confirm the QHD link is running correctly?

Boot the laptop and verify the panel reports its native 2560 x 1440 resolution with no flicker, artefacts or missing lines across the full 17.3 inch screen.
