Genuine Dell 15.6" 120Hz G-Sync LCD Ribbon Cable

This genuine Dell OEM ribbon cable connects the 15.6 inch 120Hz G-Sync LCD panel inside the Alienware 15 R4 laptop. It carries the display signal between the motherboard and the screen assembly. The part matches Dell number 8F38H and alternates 3H4G9, Y502X and DC02C00HW00. It is a new replacement component for that specific panel configuration.

Replaces a damaged or failing display cable

Swap this cable when the screen shows artefacts, flicker or no image because the original flex has cracked or the connector has lifted. The jump is worth it when diagnostics confirm the panel and GPU are healthy but the signal path is broken. It restores the 120Hz G-Sync link without changing the panel or the motherboard. Verify the part number before ordering.

Maintains signal integrity across repeated hinge

The flex construction is rated for the open and close motion of the Alienware 15 R4 chassis. Under sustained daily use it keeps the 120Hz G-Sync data stream stable without intermittent drop-outs. The cable routes through the hinge area where bending stress is highest. A secure fit at both connectors prevents micro-movement that causes flicker over time.

Questions about this item

Will the 15.6 inch ribbon cable fit my Alienware 15 R4 with the 120Hz G-Sync LCD?

Yes, this genuine Dell OEM part number 8F38H is made for the Alienware 15 R4 with the FHD 120Hz G-Sync display. It matches the 15.6 inch screen size and the specific panel variant.

How do I install the 8F38H ribbon cable and what step is often missed?

Remove the bezel and disconnect the old cable from the panel and motherboard connectors. Route the new cable along the hinge channel, then reconnect both ends firmly. The step often missed is reseating the connector locks on both sides.

When should I replace the 8F38H ribbon cable again?

Replace it if the 120Hz G-Sync screen shows flickering, lines, or no image after ruling out the panel and GPU. Physical damage from hinge stress or connector wear are the usual reasons a replacement becomes necessary.
