ASUS Zenbook 14 OLED UX3405 Review: 3K OLED Screen + 15+ Hours of Battery Life!

ASUS Zenbook 14 OLED UX3405 Review

Hello friends!
Imagine this—a laptop that captures your heart at first glance. A screen so stunning that colors appear lifelike, and blacks are so deep they seem to add a sense of depth to the display itself. A body so light and slim that you’ll slip it into your bag and completely forget it’s there. This isn’t a dream—it’s the ASUS Zenbook 14 OLED (UX3405)!
This laptop was launched in 2024 (featuring the Intel Core Ultra series), and even today—in January 2026—it remains incredibly popular because it strikes a perfect balance between performance, battery life, and design. It delivers a “MacBook-like” feel, but with Windows. Let’s dive in!

First up: that magical OLED screen.

ASUS Zenbook 14 OLED is the very soul of this laptop—a 14-inch 3K OLED touchscreen display (2880 x 1800 resolution) featuring a 16:10 aspect ratio, a 120Hz refresh rate, a 0.2ms response time, and a peak brightness of up to 1000 nits (in HDR)! It boasts a 100% DCI-P3 color gamut, is VESA DisplayHDR True Black 1000 certified, and is TÜV Rheinland-certified (meaning it’s safe for your eyes). The screen-to-body ratio stands at 87%—thanks to incredibly thin bezels.
What does this actually mean?

Colors are incredibly bright, realistic, and vivid.
Blacks are truly black—with absolutely no light bleed.
Details in HDR content are simply stunning.
Scrolling is super smooth, making gaming and movie-watching twice as enjoyable.

For instance—watch any HDR movie on Netflix, such as Stranger Things or Dune, and the dark scenes take on a whole new dimension. For photo editing (in Photoshop) or video editing, the color accuracy is absolutely professional-grade. It also features stylus support—making it excellent for drawing or taking notes.

Design and Build—Premium, Lightweight, and Robust

It weighs in at just 1.28 kg (ranging from 1.2 to 1.3 kg depending on the specific configuration)! Its thickness is a mere 14.9 mm (0.59 inches). All-Aluminum Body – Robust, resistant to fingerprints, and looks incredibly stylish in Ponder Blue or other color options.
Stylish ASUS Logo on the Lid – Delivers a premium feel. Perfect for travelers – compact and lightweight, yet features a large screen.

Check out the Slim Side Profile – See just how thin it is:

Performance – Daily tasks run super-fast thanks to the Intel Core Ultra series.
Internals: Intel Core Ultra 7 155H or Ultra 9 185H (Meteor Lake) processors – featuring 16 Cores (6P + 8E + 2LP), 22 Threads, Intel Arc Graphics, and an NPU (for AI tasks). RAM options include 16GB or 32GB LPDDR5x, with a 512GB/1TB SSD (PCIe 4.0).
This is a Copilot+ PC – Equipped with AI features such as automatic background blur, noise cancellation, and smart search capabilities.

Example: A morning Zoom meeting + 20 Chrome tabs + Excel + Photoshop + light video editing – everything runs simultaneously without any lag or freezing. It achieves strong scores in benchmarks like Cinebench; however, due to its thin profile, there is some thermal throttling under heavy loads. For daily tasks, web browsing, office work, and coding – everything runs smoothly. Light gaming (such as Valorant or League of Legends) performs well on medium settings.

Keyboard, Trackpad, and Features – Designed for Typing Comfort

The keyboard is exceptionally comfortable – offering excellent key travel, backlighting, and an ergonomic design. The trackpad is large and smooth, featuring a special “NumberPad” function – simply touch the trackpad to activate a numeric keypad! This is incredibly useful for accountants or anyone who works extensively with numbers.
