You’ve probably seen a monitor listed as 144Hz or 240Hz and wondered what that number actually buys you. Refresh rate is one of those specs that sounds technical but boils down to something simple: how many times per second your screen redraws the image. A higher number means smoother motion, and once you’ve seen it, going back feels rough.
This guide breaks it down in plain English. No jargon dumps, no marketing fluff. Just what refresh rate is, why it matters for gaming and everyday scrolling, and how to tell when a bigger number is worth paying more. If you’re shopping for a display and staring at a wall of Hz ratings, you’re in the right place.

The short answer
Refresh rate is measured in hertz (Hz), and it tells you how many times per second a monitor updates what it shows. A 60Hz screen refreshes 60 times a second. A 144Hz screen does it 144 times. More refreshes mean each frame stays on screen for less time, so fast motion looks cleaner and your cursor feels snappier.
That’s the whole idea. Everything else is detail. A budget 165Hz panel like the Acer Nitro KG241Y at $109.99 already runs circles around a standard office display, and it’s rated 4.5 stars across more than 4,000 reviews. For most people jumping up from 60Hz, the difference is obvious within seconds. You notice it the moment you drag a window across the desktop.
Pros
- 165Hz listed over DisplayPort for full refresh from compatible cards.
- Included HDMI cable reduces need for extra purchases at setup.
- NTSC 72 percent color coverage provides adequate saturation for general use.
- Low tilt range still permits basic angle tweaks for viewing comfort.
Cons
- Tilt only stand offers fewer adjustments than height or swivel models.
- VA panel can show dark scene smearing common in this price segment.
- No USB hub or speakers limits peripheral connectivity.
This is a budget tier 23.8 inch 1080p VA gaming monitor aimed at entry level gamers and general desktop users who want higher than 60Hz refresh in a small footprint.
The standout feature is the 165Hz refresh paired with AMD FreeSync Premium, which aligns frame delivery to cut tearing while keeping input lag low in variable rate scenarios typical of 1080p gaming.
Build uses a thin ZeroFrame bezel and basic tilt stand, with a matte panel that reduces reflections in typical room lighting.
Trade offs include limited ergonomic range and the motion characteristics of VA technology that can blur dark elements during rapid movement.
Buy this if you need an affordable high refresh 1080p display for everyday gaming and work. Skip this if you require height adjustment or faster pixel transitions in dark scenes.

The longer explanation
Your monitor doesn’t show continuous motion. It shows a rapid sequence of still images, and your brain fills in the gaps. Refresh rate sets how fast that sequence plays. At 60Hz, a new image appears roughly every 16.7 milliseconds. At 144Hz, it drops to about 6.9ms. At 240Hz, you’re down near 4.2ms. Shorter gaps mean less blur and less visible stutter when things move fast.
Refresh rate works alongside your frame rate, which is what your GPU produces. They’re related but not the same. Your graphics card renders frames per second (fps), and the monitor displays them at its refresh rate. If your GPU pumps out 200fps but your screen only refreshes at 60Hz, you’re leaving most of those frames on the floor. Match them up, and motion gets smooth. That’s why a fast panel and a capable GPU go together, not one or the other.
One more piece worth knowing. Refresh rate is a ceiling, not a promise. A 144Hz monitor can display up to 144 frames a second, but it won’t invent frames your GPU never made. Feed it 90fps and it shows 90. The panel’s job is to keep pace with your hardware, and the smoothness you feel comes from both parts working in sync.
It helps to picture it as a flipbook. Each page is a frame, and refresh rate is how fast you flip. Flip slowly and the motion stutters. Flip fast and it blends into smooth movement. A 60Hz screen flips 60 pages a second, a 165Hz screen flips 165. Your eyes prefer the faster flip because there’s less time between pages for motion to jump. That’s the whole trick, dressed up in a spec sheet.
History and how we got here
Old CRT monitors ran at 60Hz or 75Hz, tied to power grid frequencies and phosphor limits. When flat LCD panels took over in the 2000s, 60Hz stayed the default for over a decade. It was fine for desktop work and movies, so nobody pushed harder. Gamers noticed the ceiling first, and they pushed for more.
Around 2012, 120Hz and 144Hz panels hit the enthusiast market, and competitive players jumped on them. Then 165Hz became the new value zone for budget builds. Now 240Hz and even 360Hz displays are common, and prices keep sliding. A 240Hz panel like the AOC 25G51Z sells for $119.99 today, a number that would’ve been unthinkable a few years back. What was once a premium luxury is now entry-level territory.
Why it works this way
The reason higher Hz looks better comes down to persistence and sample timing. When an object moves across a 60Hz screen, your eyes track it smoothly, but the image only updates in chunks. That mismatch creates motion blur and a slight smearing effect. Faster refresh cuts the gap between updates, so the moving object lands closer to where your eyes expect it. The result reads as sharper motion.
There’s also input feel. A higher refresh rate reduces the delay between your action and what shows on screen. Flick your mouse on a 240Hz display and the cursor tracks tighter than on 60Hz. It’s subtle for browsing, but in fast shooters it’s the difference between reacting on time and a half-beat late. That responsiveness is a big part of why competitive players swear by high-Hz panels.
When you’d want a high refresh rate
Competitive gaming is the clearest case. Shooters, racing games, and fighting games all reward fast reactions, and a 165Hz or 240Hz panel gives you smoother tracking and lower latency. If you play Valorant, CS2, or anything where milliseconds matter, the upgrade pays for itself in feel. A 200Hz IPS option like the Acer Nitro KG251Q at $99.99 covers that need without draining your wallet, and its sub-1ms pixel spec keeps ghosting low.
But it’s not just for gamers. Scrolling web pages, dragging windows, and moving your mouse all look cleaner at high Hz. Once you’ve used a 144Hz desktop, a 60Hz one feels sluggish. For a big curved display that doubles for work and play, the SANSUI 32-inch 240Hz at $179.98 delivers both smooth motion and screen space, and it’s earned 4.5 stars from over 6,000 buyers. If you care how frame pacing holds up when fps dips, that’s where a feature like variable refresh rate earns its keep.
Pros
- 240Hz at FHD is achievable on modest GPUs like an RTX 3060 or RX 6600
- 1500R curve and 32 inch size deliver strong immersion for single-player andim racing
- 3500:1 contrast (typical VA territory) produces deeper blacks than IPS at this priceier
- VESA 100x100 support and metal stand allow flexible mounting without third-party adapters
Cons
- Limited owner feedback at time of writing makes long-term panel quality hard to verify
- 1080p stretched across 32 inches yields low pixel density around 69 PPI, visibly soft up close
- 300 nits and unspecified HDR tier suggest HDR is a marketing label, not a real HDR experience
The SANSUI 32 Inch Curved 240Hz is a budget high-refresh gaming monitor built around a 1500R curved FHD panel with FreeSync support and DP 1.4. Panel type is not specified, but the 3500:1 contrast strongly suggests VA. Target buyer is the esports player who wants 240Hz on a tight budget and can live with 1080p.
The defining feature is 240Hz refresh over both HDMI and DP 1.4, which is uncommon at this size and price. In competitive titles at FHD, a midrange GPU like an RTX 4060 or RX 7600 can sustain triple-digit frame rates to actually fed the panel. The 1500R curve ads immersion that flat 27 inch alternatives cannot match.
Trade-offs are real. FHD on a 32 inch panel produces roughly 69 PPI, so text and UI look softer than a 27 inch 1440p option. Brightness sits at 300 nits with unspecified HDR certification, meaning HDR is nominal, not VESA DisplayHDR rated. The 1ms figure is MPRT, not GtG, so expect some smearing typical of budget VA at this tier.
Buy this if you want a large curved 240Hz surface for esports and casual gaming and refuse to spend more. Skip this if you sit within a meter of the screen, need color-accurate work, or expect meaningful HDR performance from a sub-flagship VA panel.
Panel and resolution: 32 inch curved display at 1920x1080 with a 1500R curvature radius. Panel technology is not specified, though the 3500:1 contrast and 178degree viewing angle are consistent with VA. Pixel density lands near 69 PPI, notably lower than a 27 inch 1440p monitor for desktop clarity.
Motion and sync: 240Hz refresh over HDMI and DP 1.4, paired with 1ms MPRT (not GtG) and FreeSync. FreeSync compatibility with NVIDIA G-SYNC Compatible mode is not specified by the source. MPRT ratings typically involve backlight strobing and can reduce brightness, so real-world GtG smearing may be higher than the 1ms figure implies.
Color and HDR: 125% sRGB gamut, 16.7 million colors (8-bit territory), 300 nits brightness, and unspecified HDR tier. Without a DisplayHDR certification level, HDR here is a signal aceptance feature rather than a genuine HDR experience.300 nits is standard for budget monitors and limits highlight impact in bright rooms.
Connectivity and mounting: HDMI and DP 1.4 both cary 240Hz at FHD, plus a 3.5mm earphone jack. No built-in speakers. VESA 100x100 support and metal stand with tilt -5to 15 degrees. Height and swivel adjustment are not specified, so anftermarket arm may be worth budgeting for.
What to look for in a refresh rate
Don’t chase the biggest number blindly. First, check your GPU can actually feed the panel. A 240Hz monitor paired with a card that manages 90fps in your games wastes most of that headroom. Match the display to what your hardware produces. For most 1080p builds, the jump from 120Hz to 144Hz hits a smart balance of price and performance, and 165Hz costs barely more.
Also weigh panel type and adaptive sync. An IPS panel gives better color than older VA or TN, and features like FreeSync or G-Sync smooth out frame pacing when your fps dips below the refresh rate. There’s a separate spec worth reading too. A fast Hz number with sluggish pixels still smears, so it helps to understand how response time affects clarity before you commit. A budget 100Hz FreeSync panel like the Sceptre 27-inch at $97.97 shows how much value the low end packs now, with 100% sRGB coverage and 2,700-plus reviews behind it.
Common misconceptions
The biggest myth is that a high refresh rate alone makes games faster. It doesn’t boost fps. Your GPU sets frame rate. The monitor just displays what it’s given, so a 240Hz screen won’t help if your card can’t push past 60fps. They work as a pair, not a shortcut. Buy the panel to match your graphics horsepower, not the other way around.
Another mix-up: people confuse refresh rate with response time. Refresh rate is how often the screen updates. Response time is how fast each pixel changes color. Both affect motion clarity, but they’re different specs. A panel can carry a high Hz rating and still show ghosting if its pixels are slow. Check the full sheet, not just one line, and you’ll dodge the marketing traps.
A third myth trips up new buyers all the time. They assume the refresh rate on the box is what they’ll always get. It isn’t. Many high-Hz panels ship set to 60Hz out of the gate, and you have to switch them over in Windows display settings. Plenty of people run a 165Hz monitor at 60Hz for months without knowing. Cables matter too. An older HDMI cable can cap your refresh rate below the panel’s rating, so use the DisplayPort connection the spec sheet calls for.
Frequently asked
Is 60Hz enough for gaming?
It’s playable, but you’ll feel the ceiling in fast games. Casual and story-driven titles run fine at 60Hz. For anything competitive, 144Hz or higher makes a real difference in smoothness and reaction time.
Can I see the difference between 144Hz and 240Hz?
Most people notice the jump from 60Hz to 144Hz instantly. The step from 144Hz to 240Hz is subtler, and it’s mainly competitive players who benefit. If you’re on a budget, 144Hz to 165Hz is the safer value pick.
Does a high refresh rate need a strong GPU?
Yes. Your graphics card has to produce frames fast enough to fill the refresh rate. A 240Hz panel does little good if your GPU tops out at 100fps in your games. Balance the two before you buy.
Do refresh rate and response time mean the same thing?
No. Refresh rate is how often the whole screen redraws, in Hz. Response time is how fast one pixel shifts color, in milliseconds. Both shape motion clarity, so it’s worth checking each when you shop.
What refresh rate should I buy in 2026?
For most builds, 144Hz to 165Hz is the value pick and it’s cheap now. Competitive players who chase every edge should look at 240Hz. Anything above that is a niche upgrade unless you’ve got the GPU to match.
