HDMI 2.2: The New Standard for Video Transmission
Affordable 275Hz Gaming

Modern competitive gaming demands near-instantaneous response times, and the new Lecoo N2521SQ aims to meet this demand by offering specifications rarely seen in the budget segment. At its core is a 24.5-inch panel powered by Fast IPS technology. The choice of this specific matrix allows for the convergence of two critical factors: wide viewing angles and rapid pixel transition speeds, effectively eliminating motion blur during high-action sequences.
The centerpiece of the device's technical arsenal is its 275 Hz refresh rate. While 144 Hz or 165 Hz remains the industry benchmark for the mid-range segment, Lecoo is pushing into the realm of professional-grade hardware. Combined with a QHD resolution of 2560 × 1440 pixels, this results in a high pixel density, delivering a sharper and more detailed image than traditional 27-inch models with the same resolution.
The monitor's color reproduction also warrants attention. A claimed coverage of 99% DCI-P3 and 132% sRGB, paired with a Delta E < 2 accuracy rating, transforms this gaming tool into a viable solution for entry-level design and content creation. A typical brightness of 300 cd/m² is standard for this class, ensuring comfortable operation under typical office or home lighting conditions.
To enhance the gaming experience, the monitor features a "Game Plus" mode, which includes auxiliary aiming tools. Response times range from 3 ms in standard mode to 1 ms in "Speed Mode," minimizing input lag. However, such aggressive pricing necessitates certain compromises. The specifications make no mention of adaptive synchronization technologies like AMD FreeSync or Nvidia G-Sync, which may lead to screen tearing during unstable frame rates.
Connectivity is handled via a single DisplayPort 1.4—essential for achieving the maximum refresh rate—and two HDMI 2.0 ports. The stand's ergonomics are rudimentary, offering only tilt adjustment; this makes a VESA mount practically mandatory for users who require precise height calibration.
Lecoo's strategy is clear: deliver the maximum "raw" technical potential of the panel at the lowest possible price point. With a retail price of approximately $131 on the Chinese market, it stands as one of the most accessible QHD solutions with an extreme refresh rate available today.
