KTC 27 Inch 240Hz Curved Gaming Monitor, QHD 1440P 1000R Monitor, H27S25E

Bottom line: The KTC 27 Inch 240Hz Curved Gaming Monitor: 240Hz at native 2560x1440 on all four video inputs, not just DisplayPort; main trade-off: USB 2.0 port only, so no USB-C video input or fast hub duty.

Manufacturer description

The KTC H27S25E brings a 240Hz refresh rate to a 27-inch QHD panel, and the combination is what makes this curved gaming monitor punch above its class. You get 2560x1440 resolution across a 1000R curve, a tighter wrap than the more common 1500R that keeps the edges of the screen closer to your natural field of view and cuts the distortion you notice when you track targets across the panel. Adaptive-Sync support pairs the 240Hz ceiling with your GPU's frame output to eliminate tearing in fast shooters, and HDR support adds punch to highlights. Color work holds up too.

Frequently Asked Questions

Can this monitor really do 240Hz over HDMI?

Yes. KTC lists both HDMI 2.0 ports and both DisplayPort 1.4 ports as running 2560x1440 at 240Hz, so you get the full refresh rate on any of the four inputs.

Is a 1000R curve too aggressive for everyday desktop work?

1000R is tighter than the common 1500R, which KTC says more closely mimics the natural shape of your eyes and widens your field of view. It suits gaming and browsing; precision straight-line work like CAD is where a flat panel wins.

What GPU do I need to actually hit 240fps at 1440p?

That depends entirely on the game and settings. Competitive titles like CS2 or Valorant reach high frame rates on mid-range cards, while demanding AAA games at 1440p will not sustain 240fps without a high-end GPU.

Does it work with both NVIDIA and AMD graphics cards?

The monitor supports Adaptive-Sync to eliminate screen tearing, which is the open standard both AMD FreeSync and NVIDIA G-SYNC Compatible modes are built on. Check the product listing for any specific certification claims.

Is the color accurate enough for photo or design work?

KTC rates the panel at a 124% high color gamut with a 178-degree viewing angle and ships a pre-set sRGB mode with color calibration applied. That covers general design work, though the listing does not publish a Delta-E figure.
