240Hz-400Hz Monitors

Diminishing Returns and Where They Start

The jump from 60Hz to 120Hz is the one nobody misses, as it changes how the whole desktop feels, not just games. From 144Hz to 240Hz the difference remains clear in fast camera movement. Past 240Hz it narrows into something most players feel as responsiveness rather than see as smoothness, which is why this band is a competitive play purchase rather than a general upgrade. Our high refresh rate gaming guide puts the whole ladder in context so you can place this range against your hardware.

Two practical checks should come before buying. First, confirm your cable and port can carry the mode, since high refresh at higher resolutions has real bandwidth limits. Second, verify the panel is running at its rated rate once connected, because displays frequently default to a lower setting. Both steps prevent a silent cap on performance that has nothing to do with the panel itself.

Find Your High Refresh Monitor

Choose the rate your system can actually sustain, then match size and resolution to your desk. The models below group by the trade they make between raw speed and image sharpness. Consider viewing distance and whether you need a tight curve for immersion.

• 400Hz class: The 25M1 runs 1080p at 400Hz with 0.5ms response and a shielding hood, while the 25M2 Pro reaches 360Hz with 400Hz overclock in the same hooded 24.5 inch format, both built for stages where glare control matters.
• 240Hz larger and sharper: The H32S25E brings 2K at 240Hz to a 32 inch 1000R curve, and the H24S17P puts 240Hz on a 24 inch 1500R curved panel, giving you size without giving up speed, each shown among our 2K monitors.
• Fastest pixel response: The G27P6 is a 27 inch 2K OLED at 240Hz with 0.03ms, roughly two orders of magnitude quicker than typical LCD transitions, which keeps dark trails from forming.
• Fast IPS balance: The H25T7 3 pairs 240Hz with a Fast IPS panel and the H27E22P runs FHD at 280Hz on 27 inches, options that sit comfortably in the 24 to 25 inch range favored for esports.

Push Your Frame Rate Further with KTC

Explore KTC 240Hz to 400Hz monitors to match refresh, size and panel to the games you actually play. With choices from hooded 25 inch speedsters to large 32 inch curved 2K panels and OLED with instant response, you can cut frame waiting time without losing image stability. Start from your sustained frame rate, confirm the cable can carry the mode, and let the higher ceiling do the rest.

Frequently Asked Questions about 240Hz to 400Hz Monitors

Can you actually see the difference above 240Hz?

Most players notice the step from 60Hz to 144Hz immediately and from 144Hz to 240Hz clearly. Beyond 240Hz the visual difference narrows, but the reduction in frame latency is measurable and competitive players consistently prefer it.

What GPU do I need for 400Hz?

Enough to push 300 to 400 frames per second in the specific game you play, which in practice means older or well optimized competitive titles at 1080p. Modern single player games will not reach those rates on any current card.

Does refresh rate or response time matter more?

They solve different problems. Refresh rate controls how often a new frame appears, while response time controls how quickly each pixel finishes changing color. A high refresh panel with slow pixels still smears, which is why the fastest models are called out separately.

Will a high refresh panel fix screen tearing?

It reduces how visible tearing is but does not remove the cause, which is frame rate and refresh falling out of sync. Adaptive sync is the actual fix, and our screen tearing guide covers G Sync, FreeSync and frame rate capping options.
