Samsung Display ATNA40YK04-0 Review

Samsung Display ATNA40YK04-0 14-inch 2880x1800 OLED laptop replacement screen, 40-pin eDP, 100% sRGB, non-touch, glossy.

A 14-inch 2.8K OLED panel used across several thin-and-light laptops that ship with a Samsung Display OLED option, prized for true blacks and wide color gamut over the standard IPS alternative.

Compatibility

Part of the ATNA40YK-series (04-0/07-0); confirm the exact suffix against your laptop's original panel label before ordering, since OLED panels from different suffixes can vary in brightness calibration.

Which laptops this fits

Confirmed factory fit across ASUS's 14-inch OLED Zenbook line, including the Zenbook 14 UM3402/UX3402 (2022) and the Zenbook 14X UX5401, plus other Zenbook 14 OLED generations sharing the same 2.8K panel size and connector.
