Quick Answer: Refresh rate measures how many times per second a monitor redraws its image, in Hertz (Hz) — 60Hz redraws 60 times a second, 144Hz redraws 144 times. The single upgrade that matters most is 60Hz to 144Hz: DisplayNinja’s testing found 95% of users rate that jump as dramatic. Going further, from 144Hz to 240Hz, is real but smaller — roughly 75-80% can perceive it — and gains keep shrinking above that, so 144Hz-165Hz is still the practical sweet spot for most buyers, with 240Hz+ reserved for competitive gaming and 500Hz for dedicated esports.
Every monitor spec sheet leads with a Hz number now, and it’s easy to assume bigger is automatically better. It isn’t — past a certain point you’re paying for a number your eyes, your GPU, or the games you actually play can’t take advantage of. Here’s what refresh rate actually measures, which tier is worth paying for, and where the return on a higher number genuinely stops.
What refresh rate actually measures
Refresh rate is how many times per second a display redraws the entire image, expressed in Hertz (Hz). It’s a fixed property of the panel and its electronics — a 144Hz monitor can redraw up to 144 times every second, full stop, regardless of what’s being shown. A higher refresh rate means less time between each redraw, which makes moving objects look smoother and reduces the perceived blur that comes from a screen displaying the same frame for longer.
This is different from frame rate (fps), which is how many frames per second your GPU is actually rendering — a number that constantly moves based on the game, the settings, and the scene. A 144Hz monitor can only ever display up to 144 frames per second even if the GPU renders more; if frame rate and refresh rate fall out of sync, you get visible tearing, which is what adaptive sync technologies exist to fix.
The refresh rate tiers, and who each one is for
| Tier | Best for | Full guide |
|---|---|---|
| 60-75Hz | Office work, media, browsing — no gaming benefit | — |
| 144Hz | The sweet spot: dramatic smoothness jump, easy to drive | Best 144Hz monitor |
| 165Hz | What most "144Hz" panels actually ship at today | Best 165Hz monitor |
| 240Hz | Serious competitive players, noticeable but smaller gain | Best 240Hz gaming monitor |
| 360Hz | High-level esports, diminishing returns set in | Best 360Hz monitor |
| 500Hz | Dedicated esports players chasing every millisecond | Best 500Hz monitor |
A practical detail worth knowing: nearly every quality panel marketed as “144Hz” now actually ships at 165Hz or 180Hz, so buyers in that tier typically get extra headroom for free. Above 240Hz, panels are built for specific competitive titles — CS2, Valorant, Overwatch 2 — run at low settings specifically because those games are light enough to hit 300+ fps on mainstream hardware; a graphically heavy AAA game won’t get anywhere near 500 fps on most GPUs, refresh rate or not.
How much refresh rate actually matters
The 60Hz-to-144Hz jump is the one nearly every buyer notices instantly. According to DisplayNinja’s testing, 95% of users rate that difference as dramatic — it’s the single biggest perceptible smoothness upgrade available on a monitor. The next step up is real but smaller: roughly 75-80% of users can tell 144Hz from 240Hz apart, and the gap keeps narrowing at each tier after that. That’s why 144Hz-165Hz remains the tier we recommend to most buyers, and why 360Hz-500Hz panels are a purpose-built tool for competitive players rather than a general-purpose upgrade.
GPU headroom matters just as much as the panel. A mid-range card like an RTX 4060 comfortably drives 144Hz at 1080p; 1440p at 144Hz wants an RTX 4070-class card or better to stay near the panel’s ceiling most of the time. Buying a higher Hz tier than your GPU (or your game) can actually push wastes money on a number you’ll rarely see.
LG UltraGear 27GP850-B — The Sweet-Spot Pick
- Runs a genuine 165Hz out of the box — already past the "144Hz" most buyers are shopping for — with a 180Hz overclock available.
- 1ms GtG response with both G-Sync Compatible and FreeSync Premium keeps motion clean and tear-free across NVIDIA and AMD GPUs.
- The tier where the 95%-noticeable jump lives, without paying esports-panel pricing for Hz you won't use in most games.

Refresh rate vs. response time
A high Hz number alone doesn’t guarantee clean-looking motion. Response time (GtG) is how fast an individual pixel physically changes color, and it has to keep pace with the refresh rate for the extra Hz to actually show up as sharper motion. A 240Hz panel with a sluggish response time can look worse in fast motion than a 144Hz panel with a genuinely fast pixel response, because the pixels can’t finish changing color between redraws. Our monitor response time guide covers what that spec actually measures and why the advertised number is rarely the real average, and our monitor input lag guide covers how response time and input lag factor into the buying decision alongside refresh rate.
Adaptive sync: keeping refresh rate and frame rate in step
Because frame rate constantly changes and refresh rate is fixed, the two fall out of sync unless something manages it — that’s what adaptive sync does. NVIDIA G-Sync and AMD FreeSync both dynamically match the monitor’s refresh rate to the GPU’s output frame rate in real time, eliminating screen tearing without the input-lag cost of traditional V-Sync. See our best G-Sync monitor and best FreeSync monitor guides for current picks in each ecosystem — most modern gaming monitors, including budget ones, support at least one of the two.

Refresh rate on consoles
Console gaming has its own ceiling that has nothing to do with the monitor. The PS5 and Xbox Series X output up to 120Hz over HDMI 2.1 in supported games, not 144Hz or higher — so pairing either console with a 144Hz+ monitor still runs it at that 120Hz ceiling, a major upgrade over 60Hz but capped by the console rather than the display. Hitting 144Hz or above in practice requires a PC with a GPU capable of actually rendering frame rates that high.
Refresh rate by the numbers
- 95%. The share of users who rate the 60Hz-to-144Hz jump as a dramatic difference, per DisplayNinja’s testing — the single biggest perceptible refresh-rate upgrade available.
- 75-80%. The share who can perceive the smaller step from 144Hz to 240Hz — real, but a meaningfully smaller gain than the first jump.
- 120Hz. The refresh-rate ceiling for the PS5 and Xbox Series X over HDMI 2.1, regardless of the monitor’s own maximum Hz.
- 0.5ms. The gray-to-gray response time on a dedicated 500Hz esports panel like the Alienware AW2524HF — fast enough that the pixels can actually keep up with the refresh rate.
Which tier should you actually buy?
If you’re upgrading from a 60Hz office monitor, 144Hz-165Hz delivers the upgrade that will feel obvious the moment you use it — that’s the jump 95% of people notice, and it’s easy to drive with a mid-range GPU. Move up to 240Hz only if you already play competitively and want the smaller, real gain the next tier offers. Reserve 360Hz-500Hz for dedicated esports players running lightweight, high-fps titles at low settings — in a demanding AAA game, that extra headroom mostly goes unused. Whichever tier you land on, make sure the response time and adaptive sync support match it; a fast refresh rate on a slow panel doesn’t deliver the upgrade the Hz number promises.
