144Hz vs 240Hz: which refresh rate do you need?

A higher refresh rate is the single upgrade that makes a gaming monitor feel faster. But the numbers keep climbing — 144Hz, 165Hz, 180Hz, 240Hz, 360Hz, even 500Hz — and each step costs more. Here's what refresh rate actually changes, how big the difference between 144Hz and 240Hz really is, and how to match the monitor to your PC and the games you play.

What refresh rate means

The refresh rate, measured in hertz (Hz), is how many times per second a monitor draws a new image. A 60Hz screen refreshes 60 times a second; a 240Hz screen, 240 times. It's a different thing from frame rate (fps), which is how many frames your graphics card produces. You see the benefit of a fast monitor only when the two are close: a 240Hz monitor fed 70 fps still shows only 70 different images a second.

The easiest way to compare refresh rates is the time between two refreshes:

Notice the pattern: going from 60Hz to 144Hz cuts almost 10 ms off every frame, while 144Hz to 240Hz saves under 3 ms, and 240Hz to 360Hz about 1.4 ms. Every step up is real, but each one is smaller than the last.

What you actually notice

A higher refresh rate improves three things:

• Smoother motion. Camera pans, scrolling and moving targets show more in-between positions, so motion looks fluid rather than steppy.
• Clearer moving objects. On typical LCD and OLED screens, each frame is held until the next one arrives, which makes fast motion look blurred to your eyes. Shorter frames mean less of this blur, so you can track a target or read text while it moves.
• Lower latency. New information reaches the screen sooner. Combined with a high frame rate, the game feels more responsive to your mouse.

60Hz to 144Hz is the difference almost everyone sees within seconds, even on the Windows desktop. 144Hz to 240Hz is noticeable side by side and in fast games, especially for experienced players, but it's far less dramatic. Many people simply wouldn't notice it in slower single-player games.

Your PC has to keep up

This is where most buyers go wrong. To benefit from 240Hz you need a frame rate somewhere near 200–240 fps in the games you play. That's realistic in lighter competitive titles such as Counter-Strike 2, Valorant, Overwatch 2 or Rocket League on a decent mid-range PC, especially at 1080p or 1440p. In demanding single-player games, even high-end graphics cards often run well below 144 fps at 1440p or 4K with high settings.

At very high frame rates, the CPU often becomes the limit rather than the graphics card. Our explainer on CPU and GPU bottlenecks shows how to tell which one is holding you back. Upscalers and frame generation can raise frame rates in supported games; our DLSS vs FSR vs XeSS guide explains the trade-offs, including the extra latency that generated frames can add.

Variable refresh rate fills the gaps

Your frame rate is never perfectly steady. Variable refresh rate (VRR) — FreeSync or G-Sync — lets the monitor follow the graphics card, so a game running at 130 fps on a 240Hz screen is shown at 130Hz without tearing or V-Sync stutter. That makes a high-refresh monitor a safe buy even if you can't always hit its maximum. Our FreeSync vs G-Sync explainer covers which badge works with your GPU and why the VRR range matters.

Panel type matters as much as the number

The refresh rate is only part of the story. The pixels must also change colour fast enough to keep up:

• OLED panels switch almost instantly, so a 240Hz OLED looks very clean in motion. They're the most common choice at 240Hz and above at 1440p and 4K, but cost more and can be prone to burn-in with static content.
• Fast IPS panels are the mainstream choice at 144–180Hz and are widely available at 240Hz and above, with good colours and no burn-in risk.
• VA panels offer deep contrast but can smear dark transitions, which undermines a high refresh rate.
• TN panels are now mostly limited to cheap or ultra-high-refresh esports models.

Resolution and the cable

High refresh at high resolution needs a lot of bandwidth. For PCs, DisplayPort 1.4 (usually with Display Stream Compression) or DisplayPort 2.1 handles 1440p and 4K at 240Hz; check which version the monitor and your graphics card support and use the cable that came in the box. See our HDMI vs DisplayPort guide for details. Also, after plugging in a new monitor, set the refresh rate manually: in Windows 11 go to Settings → System → Display → Advanced display and choose the highest rate. Many people run a 144Hz monitor at 60Hz for months without noticing.

A common pairing in 2026: 1080p for 360–500Hz esports monitors, 1440p at 180–240Hz as the all-round sweet spot, and 4K at 144–240Hz for players with top-tier graphics cards. Screen size plays into this too; see our guide to the best monitor size for gaming.

What about consoles?

PS5 and Xbox Series X|S output up to 120Hz, and only in games that support it. A 240Hz monitor works with them, but at 120Hz at most, so for a console a 120–144Hz screen with HDMI 2.1 and VRR gives you everything the console can use. Nintendo Switch 2 is also limited to 120Hz, and only in games that support it.

So which should you buy?

• Mostly single-player, story or strategy games: 144–180Hz. Spend extra on resolution, contrast or HDR instead.
• A mix of everything on a mid-range PC: 1440p at 165–180Hz, or 240Hz if the price gap is small.
• Competitive shooters with 200+ fps: 240Hz, ideally OLED or a fast IPS.
• Serious esports players: 360Hz or more at 1080p or 1440p, with a strong CPU.
• Console only: 120–144Hz with HDMI 2.1.
