The catch

The headline 400Hz refresh rate is only possible at a non-native 1080p resolution, which makes the image noticeably softer than on a true 1080p display.

Spec, translated

The 'Dual Mode' allows switching between a sharp 1440p/200Hz for detailed games and a softer 1080p/400Hz for competitive shooters, forcing a choice between image clarity and maximum frame rate.

Lab notes

The observations that actually change the buying decision.

The 5000:1 static contrast ratio confirms a VA panel, which provides deep blacks but risks slower pixel response times ('smearing') compared to IPS, a trade-off at high refresh rates.

The 400Hz 'Dual Mode' requires running at 1080p. On a native 1440p panel, this non-integer scaling will produce a visibly softer image than a native 1080p display.

HDR10 support is listed, but the absence of a peak brightness specification (e.g., DisplayHDR 400) means it can process an HDR signal but likely lacks the luminosity for a true HDR experience.

The stand is tilt-only. The lack of height, swivel, or pivot adjustment makes a VESA monitor arm a practical necessity for proper ergonomics.

Why you should buy

This monitor is for a budget-focused gamer who wants a fast 1440p experience with the deep blacks of a VA panel. The 400Hz mode is a usable, if compromised, bonus for those who dabble in competitive titles and prioritize frame rate over sharpness.

Why you should skip

Esports purists should get a native 1080p screen for maximum clarity at high refresh rates. Anyone needing accurate color for creative work should be wary of a wide-gamut panel without a specified sRGB mode. Users without a VESA arm will find the included stand limiting.
