27-Inch Dual-Mode Gaming Monitor

The KTC H27S5 is a 27-inch curved gaming monitor built for players who want both high resolution and extreme refresh rates in one panel. It targets competitive gamers and enthusiasts who switch between detail-rich RPGs and fast-paced shooters. The 1500R curvature wraps the field of view for deeper immersion during long sessions. It is not for buyers who need a flat panel for colour-critical professional work.

WQHD 200Hz and HD 400Hz Switchable Modes

The monitor runs at 1440p resolution with a 200Hz refresh rate for sharp, responsive gameplay. A dual-mode option drops resolution to 1080p while pushing the refresh rate to 400Hz for maximum motion clarity in esports titles. The 5000:1 contrast ratio and 127% sRGB coverage deliver deep blacks and vibrant colours with HDR10 support. It cannot sustain 400Hz at 1440p, so users must choose the mode that fits the game.

HDMI 2.0 and DisplayPort 1.4 Connectivity

Two HDMI 2.0 ports handle 1440p at 144Hz and 1080p at 400Hz, while a single DisplayPort 1.4 connection unlocks the full 1440p 200Hz and 1080p 400Hz capabilities. Adaptive-Sync works across both interfaces to eliminate tearing with compatible graphics cards. The 100×100mm VESA mount and -5° to 20° tilt adjustment offer flexible mounting, but the stand provides no height or swivel movement.

Questions about this item

Will my older graphics card with HDMI 2.0 and DisplayPort 1.4 run this 27" monitor at 1440p 200Hz?

Yes, the DisplayPort 1.4 input supports 1440p at 200Hz, while the two HDMI 2.0 ports support 1440p up to 144Hz.

How can I verify the dual-mode switching between 1440p 200Hz and 1080p 400Hz is active?

Use the on-screen display to select the desired mode, then confirm the current resolution and refresh rate in your operating system's display settings or GPU control panel.

Does the box include both an HDMI and a DisplayPort cable for the 200Hz and 400Hz modes?
