Frequently Asked Questions

What resolution and refresh rate does the KTC H27S5C run?

It is a 2560x1440 QHD panel at 144Hz, driven over DisplayPort 1.4 or either of the two HDMI 2.0 inputs.

Does this monitor work with AMD FreeSync or NVIDIA G-SYNC?

KTC lists Adaptive-Sync compatibility, which reduces screen tearing in fast-paced games. Check the product listing for specific FreeSync or G-SYNC certification.

Is the 1500R curve too aggressive for a 27-inch screen?

1500R is a deeper curve than 1800R and is intended for single-monitor use at desk distance. KTC states it reduces visual distortion and eases extended viewing.

Can I wall-mount or arm-mount this monitor?

Yes, the H27S5C supports VESA wall mounting. The included stand offers -5 to 20 degrees of tilt adjustment only.
