Alphacool eDP Cable 60/40-Pin Retina 4K 21.5

This Alphacool eDP cable replaces the internal video link between the logic board and the LCD panel in a 21.5-inch iMac with Retina 4K display from Late 2015. It carries the Embedded DisplayPort signal using a 40-pin connector on the board side and a 60-pin connector on the panel side. The part is identified by APN 923-00608 and matches systems such as iMac16,2 EMC 2833.

Replaces a damaged or faulty original eDP cable

The cable is only compatible with Late 2015 21.5-inch iMacs equipped with Retina 4K screens; non-Retina units use a 30-pin panel connector and will not accept this part. The upgrade is worth it when the display shows artefacts, flickering or no image due to a worn or severed factory cable. It does not fit earlier or later iMac generations or non-4K 21.5-inch models.

Straightforward internal replacement

Installation requires opening the iMac, disconnecting the display assembly and routing the new cable through the hinge area. The 60-pin and 40-pin connectors are keyed, but forcing them can bend pins or damage the panel socket. Common issues include seating the connectors incompletely, trapping the cable against the glass adhesive or failing to reseal the display correctly.

Questions about this item

Does the 40-pin logic-board connector and 60-pin panel connector match my iMac Retina 4K 21.5" Late 2015 A1418?

Yes — the cable carries a 40-pin plug for the logic board and a 60-pin plug for the LCD panel, which identifies it as the Retina 4K version for the 21.5-inch Late 2015 A1418 (EMC 2833) models.

Which step do installers most often miss when routing the eDP cable through the hinge area?

They forget to tuck the cable under the hinge bracket before seating the display, causing the 60-pin end to bind or the 40-pin end to sit proud on the logic-board socket.

When should I expect to replace this eDP cable again under normal use?

The cable has no defined service interval; it is replaced only if the display develops flicker, artefacts or no image after the hinge has been opened and closed repeatedly over years.
