ASUS Zenbook 14 OLED UX3405 Review

ASUS Zenbook 14 OLED UX3405 with Core Ultra 7 155H, 32GB soldered RAM and a 2880x1800 120Hz OLED touch display at 1.2kg.

ASUS's flagship ultraportable pairs a bright 120Hz OLED panel with Meteor Lake and Thunderbolt 4, in one of the lightest 14-inch chassis on the market.

Overview

The Zenbook 14 OLED keeps ASUS's signature Lumina OLED panel and adds Thunderbolt 4, in a soldered-memory chassis under 1.2kg.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Expert rating8.8 / 10

The Zenbook 14 OLED weighs 1.2 kg and combines a Core Ultra 7 155H with 32GB of LPDDR5X and a 1TB drive. Its 14-inch 2880 x 1800 OLED runs at 120Hz, and the 75Wh battery is generous for a laptop this light. Thunderbolt 4 suits travelers and mobile professionals.

Graphics are integrated, so heavy gaming and GPU rendering are not a fit. The 32GB is soldered and the storage slot is full, so choose your configuration carefully.
