ASUS Zenbook 14 OLED UM3406KA
A 1.20 kg Copilot+ laptop built around a 14-inch 3K OLED panel that runs at 120Hz, with a 50 TOPS neural processor handling the AI work.
The Zenbook 14 OLED UM3406KA is ASUS's compact everyday machine, and it earns its place on a desk through restraint rather than bulk. At 1.20 kg and 14.9 mm thick, it suits students, commuters and anyone who works across two or three locations in a week. Windows 11 Home and a Ryzen AI 5 340 handle the day.
The display is the reason to choose it. A 3K 2880 x 1800 OLED running at 120Hz gives you 400 nits, full DCI-P3 coverage and a 0.2ms response, so text stays crisp at native resolution and photographs hold their colour. The 75Wh battery and 65W USB-C charger keep the package light to carry.
Ideal For
A 1.20 kg aluminium body and a 65W USB-C charger mean the whole kit fits a small bag, so carrying it between office, train and kitchen table stays painless.
The 2880 x 1800 OLED covers the full DCI-P3 gamut at 400 nits, giving you enough resolution and colour accuracy to grade images properly on a 14-inch screen.
Sixteen gigabytes of LPDDR5X and a 1TB NVMe drive cover a full course of notes, reading and recordings without constant file housekeeping or an external disk.
Key Features
The 14-inch panel runs 2880 x 1800 at 120Hz with a 0.2ms response, so scrolling and window dragging look fluid rather than smeared.
The Ryzen AI 5 340 carries an XDNA neural engine rated up to 50 TOPS, which is what qualifies this machine as a Copilot+ PC under Windows 11.
A single 1TB M.2 NVMe PCIe 4.0 drive gives you room for large project folders and fast enough throughput to open them without waiting.
The four-cell 75Wh pack charges over USB-C from a 65W adapter, so one small brick covers the laptop and travels easily in a side pocket.
A 40Gbps USB4 Type-C port sits alongside a second USB-C, a full-size USB-A and HDMI 2.1, so most desk setups connect without a dock.
At 14.9 mm thick and 1.20 kg, the aluminium shell stays genuinely portable while keeping a backlit keyboard with 1.4 mm of travel.
What the 3K panel actually gives you
Resolution on a 14-inch screen matters more than the number suggests. At 2880 x 1800 the pixels are small enough that text edges stop looking stepped, which makes long reading and code review easier on the eyes. Add 120Hz and the whole interface feels quicker, because cursor movement and scrolling are drawn twice as often. Colour is handled by the OLED panel's full DCI-P3 coverage, so photographs and video look the way they were graded rather than washed out.
Connectivity without carrying a dock
The port selection is unusually complete for a machine this size. USB4 Gen 3 Type-C runs at 40Gbps and carries both display output and power, the second USB-C does the same at 10Gbps, and there is still a full-size USB 3.2 Gen 1 Type-A for older peripherals. HDMI 2.1 drives an external monitor directly, and the 3.5mm combo jack takes wired headsets. For most people that removes the dongle entirely.
Portability, battery and the practical day
Weight is where compact laptops are won or lost. This one lands at 1.20 kg in a 14.9 mm aluminium chassis, light enough that you stop planning around it. The 75Wh battery is large for the class, and because charging runs over USB-C from a 65W adapter, the power brick is small too. A Full HD infrared camera with a physical privacy shutter handles Windows Hello sign-in and video calls, and the backlit keyboard's 1.4 mm travel keeps typing accurate on a train tray table.
How It Compares
| What You Need | Technology | Practical Benefit |
|---|---|---|
| Long document work | 3K OLED at 120Hz | Small, sharp text with smooth scrolling, so a full day of reading and editing is less tiring on the eyes. |
| Photo editing | 100% DCI-P3 coverage | Colours on screen match the wide gamut images were graded in, so edits hold up when you export them. |
| Working away from mains | 75Wh four-cell battery | A large pack for a 14-inch machine, charged from the same small 65W USB-C brick you already carry. |
| Desk docking | USB4 40Gbps and HDMI 2.1 | One cable to a monitor or a direct HDMI run, with power delivery over the same USB-C port. |
| On-device AI features | 50 TOPS XDNA neural engine | Copilot+ workloads run locally on the neural processor rather than leaning on the main CPU cores. |
| Carrying all day | 1.20 kg, 14.9 mm chassis | Light enough for a backpack you already use, with an aluminium shell that handles daily travel. |

The Verdict
Strengths
- 14-inch 3K OLED at 120Hz with 400 nits
- Full DCI-P3 colour coverage for photo work
- 1.20 kg aluminium chassis, 14.9 mm thick
- 1TB NVMe PCIe 4.0 SSD as standard
- USB4, second USB-C, USB-A and HDMI 2.1
- 75Wh battery charging over 65W USB-C
- Infrared camera with physical privacy shutter
Considerations
- The 16GB of LPDDR5X is soldered to the board, so memory cannot be increased later and should be sized correctly at purchase.
- This configuration has no touchscreen, which rules out pen input and direct screen interaction if that is part of your workflow.
- Graphics come from the integrated Radeon 840M only; there is no discrete GPU for heavy 3D rendering or sustained gaming.
What's in the Box
