A 240Hz monitor is worth it if you play fast shooters at frame rates that actually approach 240 per second and you want the sharpest motion your budget can buy. It is not worth chasing if your graphics card averages 90 to 140 frames per second in the games you play, because a 144Hz panel will show you nearly everything a 240Hz panel can in that situation. This guide explains the frame-time math, the cable and port traps that quietly cap refresh rate, and how to decide with your own numbers, then lists four 1440p monitors that go past 240Hz.

Quick Verdict
| Your situation | Our verdict |
|---|---|
| Competitive shooter player, GPU holds 200+ fps in your main game | Yes. 240Hz or higher is the first upgrade where the extra refresh is actually being fed. |
| Mostly single-player or open-world games at 60 to 100 fps | No. Buy 144Hz to 165Hz and spend the difference on the GPU or on image quality. |
| Mid-range GPU, 1440p, mixed library | Probably not. 144Hz to 170Hz with adaptive sync is the sweet spot until your frame rate climbs. |
| Already own a 144Hz monitor and hit 200+ fps | Worth considering, but expect a smaller jump than the one from 60Hz to 144Hz. |
| Want one monitor for work, movies and gaming | Pick resolution, panel quality and ports first. Refresh rate above 144Hz is a bonus, not a requirement. |
| Shopping the budget end of the 240Hz tier | Fine for 1440p IPS, but check which port delivers the full refresh rate and what the stand allows. |
The Key Differences
The frame-time math: why each jump feels smaller
Frame time is simply 1,000 divided by the refresh rate in hertz. At 60Hz a new image arrives every 16.67 ms. At 144Hz it is 6.94 ms, and at 240Hz it is 4.17 ms. Moving from 60Hz to 144Hz therefore removes about 9.7 ms between images, while moving from 144Hz to 240Hz removes only about 2.8 ms. The next step, 240Hz to 360Hz, would remove just 1.4 ms more. Every jump costs more money and delivers a smaller absolute change.
That does not make the change invisible. Blur Busters, which has published the most widely cited work on display motion, describes a rule of thumb: on a sample-and-hold display, 1 ms of persistence equals about 1 pixel of motion blur for every 1,000 pixels per second of on-screen movement. By that rule, a fast pan at 1,000 px/s leaves roughly 6.9 pixels of trailing blur at 144 fps and roughly 4.2 pixels at 240 fps, assuming the pixels respond instantly. It is a real improvement, but it is the size of a subtle sharpening, not the shock of going from 60Hz to a high-refresh display for the first time.
The refresh rate only helps if your frame rate keeps up
A 240Hz monitor showing a game at 90 fps is not displaying 240 distinct images each second. With adaptive sync it simply refreshes at 90Hz, and its motion clarity is that of a 90Hz display. Blur Busters forum discussions make the same point: persistence benefits come from matching frame rate to refresh rate, while a mismatch only helps a little with scanout latency. So the practical question is not “can the monitor do 240Hz” but “does my PC render close to 240 frames per second in the games I care about, with 1 percent lows that do not collapse”. The CPU matters as much as the GPU here, because at esports settings the processor is often the limiter.
Pixel response can matter more than the headline refresh number
If the panel cannot finish a color transition within one refresh interval, a 240Hz label buys you ghosting rather than clarity. At 240Hz each frame lasts 4.17 ms, so a panel with slow transitions in dark colors will smear regardless. Manufacturers advertise figures such as 0.3 ms or 1 ms, but those are usually best-case gray-to-gray or MPRT numbers at the strongest overdrive setting, which can introduce overshoot (inverse ghosting). Treat the figure as marketing until an independent measurement of your exact model shows otherwise. Several listings below quote 0.3 ms to 1 ms; confirm against measured reviews if motion quality is your main reason to buy.
Ports and cables: the cap nobody mentions
Refresh rate is limited by the weakest link between your GPU and the screen. DisplayPort 1.4 carries about 25.92 Gbps of usable video bandwidth. A 2560×1440 signal at 240Hz in 8-bit color needs roughly 21 Gbps of active pixel data, so it fits with efficient timings. The same resolution at 10-bit color, around 26.5 Gbps before blanking, exceeds that limit and requires Display Stream Compression (DSC) supported by both the GPU and the monitor, or a lower refresh rate. HDMI 2.0 is a much tighter limit; several 1440p monitors cap their HDMI 2.0 inputs at 144Hz even when the DisplayPort input reaches 240Hz or more. The practical rule: use DisplayPort for the full refresh rate unless the spec sheet says its HDMI port is 2.1.
Specs at a glance
| Refresh rate | Frame time | Change from previous tier | Who it suits |
|---|---|---|---|
| 60Hz | 16.67 ms | Baseline | Office work, slow games |
| 144Hz | 6.94 ms | About 9.7 ms shorter | Most PC gamers |
| 240Hz | 4.17 ms | About 2.8 ms shorter | Competitive players with high fps |
| 360Hz | 2.78 ms | About 1.4 ms shorter | Esports specialists, mostly 1080p |
The frame times are arithmetic and exact. How large the benefit feels depends on your eyes, your game and your frame rate, so treat the right-hand column as guidance rather than measurement.
How to Decide
Run through this checklist with your own numbers before buying.
- Measure your frame rate. Open the in-game benchmark or an overlay and note the average and the 1 percent low in your two most-played games at your preferred settings. As a rule of thumb, a 240Hz purchase makes sense when your average is at least 180 to 200 fps. If you average 110 fps, a 144Hz to 165Hz monitor captures most of the value.
- Check the CPU. If your frame rate does not change when you lower graphics settings, the processor is the bottleneck, and a faster monitor will not help.
- Confirm your outputs. Find out whether your GPU has DisplayPort 1.4 or newer. A monitor that reaches 240Hz only on DisplayPort is useless on a GPU you plan to connect over HDMI 2.0.
- Pick resolution first. A 27-inch 1440p panel is a better all-round choice than a 1080p 240Hz panel for most people, but 1440p at 240 fps asks far more of the GPU.
- Compare marginal value. Ask what else the same money could buy: a faster graphics card, more storage or a better chair. If the answer is a card that lifts you from 100 to 160 fps, that usually beats a monitor that can show frames you do not render.
Worked example: you play a shooter at 1440p and average 165 fps with 1 percent lows near 110 fps. A 240Hz monitor will display 165 distinct images per second at best, so you gain mostly from lower persistence and lower scanout delay. A 165Hz monitor would present the same frames with almost no wasted headroom. If you later upgrade the GPU and reach 230 fps, the 240Hz panel starts paying for itself.
Products That Fit
All four monitors below are 27-inch 1440p panels that advertise refresh rates at or above 240Hz. Specifications come from the retailer listing fields and manufacturer descriptions; anything not stated there is marked “confirm on listing”.
AOC Q27G41ZE – 1440p IPS for players who want 240Hz without a premium badge
As an Amazon Associate we earn from qualifying purchases at no extra cost to you.
This model suits the “I am upgrading from 144Hz and my GPU can feed it” situation. The listing quotes 240Hz over DisplayPort, with the title also mentioning an overclocked 260Hz mode, so confirm which figure you get on the exact unit. It uses an IPS panel with Adaptive-Sync that works with both AMD and NVIDIA cards, which matters for smooth motion when your frame rate wobbles below the maximum.
- 27-inch QHD (2560×1440) IPS display
- 240Hz via DisplayPort, 0.3 ms MPRT quoted
- Adaptive-Sync, Shadow Control and Game Mode presets
- Tilt adjustment from -3 to +21 degrees (no height adjustment listed)
Caveat: the stand is tilt-only according to the listing, and the 0.3 ms figure is an MPRT claim, not a gray-to-gray measurement, so do not read it as proof of ghost-free dark transitions.
ASUS TUF Gaming VG27AQM5A – 300Hz headroom for high-frame-rate shooters
If you already hold well over 240 fps and want margin above the 240Hz tier, this 300Hz panel fits the “competitive player” row of the verdict table. The extra refresh rate is only valuable if your system supplies the frames, and the frame-time gain over 240Hz is under 1 ms, so this is for people who have exhausted cheaper upgrades. ELMB Sync, ASUS’s motion-blur reduction, is listed as working alongside variable refresh rate.
- 27-inch QHD (2560×1440) Fast IPS, 300Hz
- 0.3 ms GTG listed as the minimum (best-case) response
- ELMB Sync with variable refresh rate, G-SYNC listed
- Weight 10.1 pounds with stand; height and swivel options: confirm on listing
Caveat: 300Hz at 1440p increases the bandwidth you need, so confirm you are using the right DisplayPort input and cable, and remember the best-case response number applies to the strongest overdrive mode.
SANSUI 27-inch 1440p 260Hz/240Hz – budget Fast IPS with a port catch
This is the “shopping the budget end” pick. The listing describes a 27-inch Fast IPS panel that runs at 240Hz out of the box and up to 260Hz as an overclock, with FreeSync Premium, HDR10 and 98 percent DCI-P3 claimed. It is a useful illustration of the port rule: the listing states that the two DisplayPort 1.4 inputs reach the full refresh rate while the two HDMI 2.0 inputs top out at 144Hz.
- 27-inch 2560×1440 Fast IPS, 240Hz with 260Hz overclock mode
- 2x DisplayPort 1.4 (full refresh) and 2x HDMI 2.0 (144Hz maximum)
- FreeSync Premium, HDR10, 98 percent DCI-P3 quoted
- Tilt-only stand with a 100×100 mm VESA mount per listing
Caveat: overclocked refresh rates are not guaranteed, an HDR10 label on a monitor at this level mainly means it accepts the signal (the listing quotes 320 nits of brightness), and the tilt-only stand may push you toward a monitor arm.
Hikers 27-inch curved 280Hz – curved VA for dark scenes, with a trade-off
This model is a different kind of panel and suits the player who values contrast over IPS color uniformity. The listing describes a 1500R curved fast VA display with a 5000:1 contrast claim, 280Hz, two HDMI 2.1 ports and one DisplayPort 1.4, so it avoids the HDMI 2.0 trap described above. The curve and higher contrast help dark scenes, while VA panels generally have slower dark-color transitions than IPS, which is relevant at these frame times.
- 27-inch 2560×1440 curved fast VA, 280Hz/240Hz
- 1 ms MPRT and FreeSync listed; G-Sync compatible over HDMI 2.1 with NVIDIA cards per listing
- 2x HDMI 2.1 and 1x DisplayPort 1.4
- Tilt -5 to 15 degrees, 100×100 mm VESA, no built-in speakers
Caveat: confirm independent response-time measurements before assuming VA can keep up at 240Hz and above, and note that a curved screen may feel odd for non-gaming work such as photo editing.
Common Mistakes
- Buying 240Hz for a PC that averages 80 to 100 fps and expecting the full benefit.
- Plugging into an HDMI 2.0 port and leaving Windows at 144Hz without noticing.
- Forgetting to select the higher refresh rate in Windows display settings after connecting a new monitor.
- Trusting a 0.3 ms or 1 ms response claim instead of looking for independent motion measurements.
- Choosing 1080p 240Hz over 1440p without considering that a sharper picture helps in every game, not just fast ones.
- Ignoring the stand: a tilt-only base can force awkward eye-height compromises on a desk.
Questions
Can you really see the difference between 144Hz and 240Hz?
Many players can, especially in fast camera pans and tracking tasks, but the difference is smaller than the jump from 60Hz to 144Hz. The frame-time gap is about 2.8 ms, and it only appears when the game runs near 240 fps.
Do I need a special cable for 240Hz at 1440p?
Use a DisplayPort cable certified for at least DisplayPort 1.4, or the one supplied with the monitor. At 1440p and 240Hz in 8-bit color a clean DisplayPort 1.4 link is generally enough, while 10-bit color at that rate may need DSC support in both the GPU and the monitor.
Is 240Hz worth it for 4K?
Only if you have a very powerful GPU and play lighter or older games at high frame rates. At 4K the processing load rises sharply, so most players reach 240 fps only in esports titles with reduced settings.
Will a 240Hz monitor reduce input lag?
It can reduce display scanout delay slightly, and higher frame rates reduce render latency, but the total depends on your mouse, game engine, GPU queue and the monitor’s own processing. The monitor is one part of the chain, not the whole of it.
Is 240Hz overkill for non-competitive games?
For story-driven or graphically heavy games that run at 60 to 100 fps, yes in practice. A good 144Hz to 170Hz panel with adaptive sync delivers a smooth experience at a lower cost and lower GPU demand.
