Manufacturer description

The KTC H27T27S puts QHD gaming on a budget desk without the usual compromises. Its 27-inch HVA panel runs 2560x1440 at 144Hz, so fast-paced shooters and racers resolve cleanly instead of smearing, and both G-SYNC and FreeSync adaptive sync are supported to cut screen tearing when your frame rate swings.

Frequently Asked Questions

Does the KTC H27T27S really hit 144Hz at 1440p?

Yes. The panel is native QHD 2560x1440 at 144Hz. Use the DisplayPort input and enable the 144Hz mode in Windows display settings, since many monitors default to 60Hz on first connection.

Will this monitor work with an NVIDIA card?

It is listed as compatible with both G-SYNC and FreeSync, so adaptive sync works on NVIDIA and AMD GPUs. Turn G-SYNC on in the NVIDIA Control Panel after connecting over DisplayPort.

Is 300 nits bright enough for my room?

300 nits handles a normally lit office or a room with indirect daylight. If your desk faces a bright window or sits under strong overhead light, you will want a brighter panel.

Can I mount it on a monitor arm?

Yes, it has VESA mount support, so it fits standard arms and wall brackets. The included stand only adjusts tilt, from -5 to 15 degrees, so an arm is the practical route to height and swivel.

Can I connect a PS5 or Xbox to it?

Yes. It has HDMI and DisplayPort inputs, so a console and a PC can both stay connected, and a headphone output jack handles audio. Console refresh support depends on the system's own output settings.
