Review Asus ExpertBook PM3406
Asus ExpertBook PM3406
AMD Ryzen AI 7 350 · AMD Radeon 860M · 16GB DDR5-5600 (Single‑Channel) · 512GB SSD · 14.0″ 1200p IPS 60Hz · 1.443 kg
Affordable 14‑inch office laptop with aluminium chassis, good CPU performance, excellent battery life (~14 hours), and great speakers. Features Wi‑Fi 7, 2× SO‑DIMM slots, 2× M.2 SSD slots, and a 3‑year warranty. However, the IPS display has poor colour gamut (58% sRGB), single‑channel RAM cripples GPU performance, no USB4/Thunderbolt, and webcam is weak. Priced around €979 (~$1,050) – solid value with long warranty.
Display Panel – 60Hz IPS, Poor Colour Gamut (No PWM)
Panel model: MNE007QS3-6 – 14.0″ 1920×1200 60 Hz IPS (matte).
| Specification | Value |
|---|---|
| Brightness | ~310 cd/m² (avg), peak 320 cd/m² – decent |
| Contrast | 1,231:1 – solid |
| Colour Coverage | 58.1% sRGB, 39.3% DCI‑P3 – very poor |
| Accuracy (uncalibrated) | ΔE 5.1 avg, ΔE max 18.1 – poor |
| Accuracy (calibrated) | ΔE 4.9 – still poor |
| Response Time (B‑W) | 17 ms – slow |
| Response Time (GtG) | 27.6 ms – slow |
| PWM | None detected – flicker‑free |
| Refresh Rate | 60 Hz – basic |
| Finish | Matte – anti‑glare |
- No PWM – eye‑friendly
- Decent brightness – usable indoors
- Poor colour gamut – only 58% sRGB – unfit for creative work
- Slow response times
- 2.5K 144Hz IPS option available – recommended
The display has poor colour gamut (58% sRGB) – fine for office work, but the 2.5K 144Hz option is a worthwhile upgrade.
Keyboard & Touchpad – Comfortable Typing
- Keyboard: Generous travel, precise stroke – comfortable
- White backlight (standard)
- Fingerprint sensor in power button
- Keystrokes could be quieter
- Touchpad: 13 × 8.5 cm – good gliding, precise
- Mechanical clicks are not too loud
The keyboard offers comfortable typing with generous travel. The touchpad is precise and smooth.
Ports & Connectivity – Good Selection (No USB4/Thunderbolt)
- Left: USB‑C 3.2 Gen 2 (10 Gbps, DP, PD), HDMI 2.1, USB‑A 3.2 Gen 1 (powered), USB‑C 3.2 Gen 2 (10 Gbps, DP, PD), 3.5mm audio
- Right: USB‑A 3.2 Gen 1, Gigabit Ethernet, Kensington lock
- 2× USB‑C (10 Gbps) – decent
- Gigabit Ethernet – good for office use
- No USB4/Thunderbolt 4 – limited to 10 Gbps
- Wi‑Fi 7 (Mediatek MT7925) – ~1,842 Mbit/s transmit
- Weak 1080p webcam – poor image quality
- IR sensor and privacy shutter
Connectivity is decent with Gigabit Ethernet and Wi‑Fi 7, but no USB4/Thunderbolt 4 is a miss.
Serviceability & Upgradeability – Excellent
Bottom cover: Standard screws – easy to remove. 2× SO‑DIMM slots and 2× M.2 SSD slots.
| Component | Replaceable? | Difficulty | Notes |
|---|---|---|---|
| SSD #1 (2280) | ✅ Yes | Low | M.2 2280 PCIe4 – occupied, replaceable |
