KTC has unveiled the Master 27M1 Plus, a 27-inch gaming monitor that pushes refresh-rate boundaries with an overclockable 400Hz mode. Priced at $353 and landing December 11, 2025, this display targets competitive gamers who want top-tier speed without sacrificing color accuracy.
Speed, panel, and color — what you need to know
The Master 27M1 Plus uses a fast IPS panel at 2560×1440 (2K) with a native 360Hz refresh rate and an Overclock mode that bumps it to 400Hz. With a 1ms GtG response time when OverDrive is enabled and Adaptive Sync support, the monitor is built to reduce motion blur and eliminate tearing in fast-paced titles. Want buttery motion for esports? This one aims squarely at that audience.
But it’s not all about raw speed. KTC includes factory calibration with Delta E < 2, 99% sRGB and 96% DCI-P3 coverage, and HDR400 support with a 400-nit peak brightness. Blue-light reduction features are also on board to help limit eye fatigue during long sessions.
Practical controls include a five-level OverDrive system for fine-tuning motion clarity and presets tuned for console gaming, general play, and FPS shooters. A six-axis color calibration tool gives more granular control over red, green, blue, cyan, magenta, and yellow channels — useful for creators who also game on the same screen.
Physical ergonomics are thoughtful: a fully adjustable stand with height, tilt, swivel and pivot adjustments, a foldable headphone hook, a precise angle scale, and detachable side light-shields for reduced glare. The monitor weighs 5.7 kg and consumes under 90W in typical use.

Connectivity is competitive: two HDMI 2.1 ports and two DisplayPort 1.4 inputs — each capable of handling 1440p at 400Hz — plus a 3.5mm headphone jack, a USB 2.0 port and a Mini USB. At $353, KTC is positioning the Master 27M1 Plus as an attractive mid-priced option for players prioritizing ultra-high refresh rates and solid color performance.
Whether you’re chasing higher frame counts in FPS matches or want a fast, color-accurate screen for streaming and editing, the Master 27M1 Plus blends esports-grade motion with practical features. Will 400Hz become the new competitive standard? For gamers focused on the smallest edge, this monitor is worth watching.
