At a Glance
- 240 Hz refresh rate for silky-smooth gaming.
- 16-inch IPS panel with 100 % sRGB / 100 % P3 color coverage.
- Runs on a single USB-C cable, but weak speakers and power quirks may require an extra adapter.
- Why it matters: Portable gamers get high-end performance, yet need to plan for power and audio limitations.
The InnoView PM408 delivers a 240 Hz refresh rate and a 16-inch IPS panel that covers the full sRGB and DCI-P3 gamuts, making it a strong choice for on-the-go gaming and media. However, the monitor’s built-in speakers are underwhelming, and using only one USB-C connection can trigger power cycling, so an auxiliary power source is often needed.

Performance & Display
The screen peaks at about 275 nits of brightness and offers a contrast ratio just over 1,000:1. Its 2,560 × 1,600 pixel resolution gives a sharp image, and the panel’s FreeSync support keeps motion smooth. During a test session of the action game Sifu, the PM408 showed only brief ghosting that didn’t affect gameplay.
- Sharp, high-contrast image with good color accuracy.
- Fast 240 Hz refresh rate and FreeSync for fluid motion.
- Wide color gamut covering 100 % of both sRGB and DCI-P3.
- Single-cable USB-C connectivity with an extra HDMI port.
- Lightweight and a sturdy metal frame for portability.
Power & Audio
The monitor’s built-in speakers are noticeably weak, and running them at full volume while pushing the display to maximum settings on a single USB-C cable caused the PM408 to power cycle. Lowering the volume or connecting an additional USB-C adapter stabilizes the unit. The metal stand is solid, but the controls on the back edge are hard to reach, and no protective sleeve is included.
- Weak speakers that require low volume for stability.
- Power cycling when using only one USB-C cable at max settings.
- No protective sleeve for travel.
- Controls positioned awkwardly around the back edge.
