27-inch 240 Hz curved gaming monitor

The KTC H27S25E is a 27-inch curved gaming monitor built around a 1000R HVA panel. It targets competitive players who want high refresh rates and immersive geometry in a single display. The 1 ms response time and Adaptive Sync support aim to keep motion sharp during fast-paced titles.

2K QHD resolution with 240 Hz headroom

A 2560 x 1440 resolution at 240 Hz gives detailed images while leaving headroom for high frame rates in modern shooters. The 2500:1 contrast ratio and 300 cd/m² brightness handle dark scenes and bright highlights adequately. HDR10 support adds a wider luminance range, though peak brightness limits its impact in very bright rooms.

Tilt stand and VESA mounting flexibility

The stand provides tilt adjustment for quick ergonomic tuning. VESA compatibility allows the monitor to be mounted on arms or walls, freeing desk space for multi-monitor arrays. Connectivity includes two HDMI 2.0 ports, two DP 1.4 ports and a USB 2.0 port, covering PCs and consoles without adapters.

Questions about this item

Will my older graphics card that only has HDMI 2.0 run this monitor at 240Hz and 2560x1440?

HDMI 2.0 on this monitor supports the full 2560x1440 resolution at 240Hz, so an older card with HDMI 2.0 can drive the panel at its maximum refresh rate without needing DisplayPort.

How can I verify the 1 ms response time and 240Hz refresh rate are actually active after I connect the monitor?

Open the on-screen display and confirm the refresh rate reads 240Hz, then set the overdrive option to its fastest setting; the panel will then operate at the specified 1 ms response time.

Does the box include both an HDMI 2.0 cable and a DisplayPort 1.4 cable, or do I need to buy one separately?

The package contains the monitor, stand, power cable, and one DisplayPort 1.4 cable; an HDMI 2.0 cable is not included and must be purchased separately if required.
