High-Refresh-Rate Monitors: Do 144Hz and 240Hz Actually Make a Difference?

Refresh rate is one of the most visible specifications in gaming monitor marketing. 144Hz, 240Hz, 360Hz—the numbers keep climbing, and the marketing claims become increasingly confident about the competitive edge each step provides. Whether those differences are perceptible, meaningful, or worth the price premium requires separating the perceptual science from the sales copy.

The short version: going from 60Hz to 144Hz makes a real, visible difference that most people notice. Going from 144Hz to 240Hz makes a real but smaller difference that competitive gamers benefit from. Going beyond 240Hz enters territory where diminishing returns become very pronounced for most use cases. The longer version requires understanding what refresh rate actually does to your perception of motion.

What Refresh Rate Actually Controls

A monitor’s refresh rate is the number of times per second it draws a new image from the GPU’s output. At 60Hz, the display updates 60 times per second; each frame occupies the screen for approximately 16.7 milliseconds before being replaced. At 144Hz, each frame occupies the screen for approximately 6.9 ms; at 240Hz, approximately 4.2 ms.

The perceptual consequence is twofold. First, higher refresh rates mean motion is represented by more samples per second, producing smoother apparent movement when the framerate matches or approaches the refresh rate. At 60fps, fast-moving objects jump between positions with visible discreteness at close inspection; at 144fps, the apparent motion is substantially smoother. Second, higher refresh rates reduce the time between when a frame is rendered and when it appears on screen—contributing to lower perceived input latency, which matters for the feel of mouse or controller input in real-time games.

Input lag is the chain of delays between a physical input and its visual representation: polling rate of the input device, GPU render time, and display refresh delay. A 60Hz display adds a worst-case frame delay of 16.7 ms; a 240Hz display adds a worst-case frame delay of 4.2 ms. For competitive first-person shooters where millisecond timing matters, this reduction in worst-case display latency is a genuine performance factor—not just a perceived one.

The 60Hz to 144Hz Jump: Visible and Genuine

The transition from 60Hz to 144Hz is one of the most consistently reported visible improvements in display technology. Unlike the 4K-to-8K resolution debate where perceptual benefit depends on viewing distance and content availability, the 60-to-144Hz difference is perceptible in everyday use—scrolling through a webpage, moving the mouse cursor, playing any game with fast on-screen motion. The improvement is not subtle and doesn’t require controlled comparison to notice.

The visual improvement comes from two sources: reduced sample-and-hold motion blur (the blur that occurs when a static image is held on screen while the eye tracks moving objects) and smoother apparent motion from the higher sample rate. On a 60Hz display, a moving cursor trails behind itself perceptually because the eye moves continuously while the display updates in discrete jumps. On a 144Hz display, the update frequency is high enough that this perceptual gap is substantially reduced.

For anyone still using a 60Hz monitor for gaming or general computer use, the upgrade to 144Hz is the single highest-impact display improvement available at reasonable cost. 144Hz IPS monitors are now available at prices that are entirely accessible—a significant decline from the premium pricing of earlier years.

144Hz to 240Hz: Real But Context-Dependent

The jump from 144Hz to 240Hz is a measurably smaller perceptual improvement than 60Hz to 144Hz, but it is still real under specific conditions. Studies on display refresh rate perception show that trained observers can distinguish 120Hz from 240Hz under controlled conditions, particularly for rapidly moving targets. For competitive gaming in fast-paced genres—counter-strike-style tactical shooters, battle royale games where tracking moving targets at close range matters—the additional smoothness and reduced worst-case input lag from 240Hz provides a measurable advantage over 144Hz.

Whether that advantage is meaningful in practice depends substantially on the player’s skill level and the specific game. At the level where professional esports players compete, where individual match outcomes can hinge on timing differences of less than 100 ms, display latency differences matter. For amateur and casual players, where shot accuracy is dominated by aim skill and game knowledge rather than hardware precision, the difference between 144Hz and 240Hz is unlikely to materially affect competitive outcomes.

240Hz monitors do require significantly more GPU performance to provide matching framerates. A GPU capable of rendering 240+ frames per second in demanding games is a high-end, expensive GPU. Running a 240Hz monitor at 144 fps provides limited benefit over a 144Hz monitor—the additional headroom is wasted. Buyers considering 240Hz monitors should ensure their GPU can actually deliver the framerate to use it.

Beyond 240Hz: Diminishing Returns

360Hz monitors exist and are marketed primarily to professional esports players. The difference between 240Hz and 360Hz is increasingly difficult to demonstrate perceptually under real-world conditions—most people cannot distinguish the two in double-blind testing. At these frequencies, other factors (input device polling rate, operating system input processing overhead, game engine frame scheduling) become larger contributors to input latency than the monitor refresh rate itself.

500Hz and 600Hz monitors were demonstrated at CES 2024 and are beginning to appear in the high-end market. These serve the narrow elite competitive use case—professional esports players for whom any measurable latency advantage is worth pursuing—and are essentially irrelevant for mainstream gaming use.

Panel Technology Matters As Much As Refresh Rate

Refresh rate marketing sometimes obscures panel technology trade-offs that affect everyday visual quality more significantly than the difference between 144Hz and 240Hz.

TN (Twisted Nematic) panels were the dominant technology for high refresh rate gaming monitors for years because they could achieve fast pixel response times (1 ms GTG or less) at a lower cost than alternatives. Their weakness is poor colour accuracy and narrow viewing angles. IPS (In-Plane Switching) panels produce substantially better colour, wider viewing angles, and are preferred for mixed gaming and productivity use; they have improved in response time to where ghosting is minimal at 144Hz+ on quality panels. VA (Vertical Alignment) panels offer the best contrast ratios of the three (deep blacks are genuine, not the “near-black” of IPS and TN), at the cost of slower pixel response that can produce visible ghosting at high refresh rates on some content.

OLED gaming monitors—available at premium prices and growing in panel availability—combine pixel-level contrast (true black), excellent colour reproduction, and extremely fast response times (sub-0.1 ms) that make ghosting essentially non-existent even at high refresh rates. For buyers with sufficient budget, OLED gaming monitors represent the current performance ceiling.

Variable Refresh Rate: The Specification That Matters More

For most gaming use cases, adaptive sync technology—AMD FreeSync (and its variants) and NVIDIA G-Sync (and G-Sync Compatible)—matters more than the peak refresh rate number. Adaptive sync allows the monitor’s refresh rate to dynamically match the GPU’s instantaneous framerate, eliminating screen tearing without the input latency cost of V-Sync. A game running at 80–100 fps on a 144Hz FreeSync monitor tears no frames and feels smoother than the same game on a 144Hz non-adaptive monitor with V-Sync enabled.

The practical implication: a 144Hz IPS monitor with wide FreeSync range will produce a better everyday gaming experience than a 240Hz TN monitor without adaptive sync for a player whose GPU produces 100–160 fps in typical games. The adaptive sync range—how wide a framerate range the sync operates over—matters more than the peak refresh rate in many real-world use patterns.

The Buying Decision

For a player upgrading from 60Hz who games across a variety of genres: 144Hz IPS with adaptive sync is the right choice. The improvement from 60Hz is dramatic; the panel quality of IPS serves both gaming and non-gaming use; and the cost is accessible.

For a dedicated competitive FPS or battle royale player with a capable GPU: 240Hz makes sense. The additional smoothness and latency reduction is genuinely beneficial in those specific genres, and the price premium for 240Hz has dropped significantly.

For casual or console gamers: most consoles cap at 60fps or 120fps for the majority of titles. A 120Hz display—increasingly available as a feature in high-quality TVs—is the practical ceiling for console gaming, and 240Hz+ monitors provide no benefit in that use case.

The specifications that matter more than peak refresh rate: adaptive sync support and range, panel technology for colour and contrast quality, and whether the GPU connected to the monitor can actually deliver framerates that utilise the monitor’s top spec. Buying a 240Hz monitor to run at 80fps without adaptive sync is a poor use of money. Buying a 144Hz IPS with FreeSync for a system that runs most games at 90–120fps is a very good use of money.
