Finding the best 1440p 240Hz monitor can be a quite tricky prospect if you aren’t fully up to speed with the latest gaming monitor tech and news. Today’s market is flooded with a sea of high-performance 1440p panels that span the entirety of the pricing spectrum. It doesn’t matter whether you’re looking for a esports gaming monitor or a display more tailored towards everyday usage, there is a 1440p 240hz monitor that suits your exact needs.

  • Excellent colors right out of the box
  • Native FreeSync support & G-Sync compatibility
  • No native G-Sync support like the previous model

One of the best 1440p 240Hz monitors in recent times has to be he hugely impressive Alienware AW2721D – a monitor we reviewed back in May 2021 that really delivered on all fronts. However, that model is harder to find readily available these days, so we’re instead going to suggest its successor the AW2723DF.

The AW2723DF showcases all the qualities you could want from a high-end gaming monitor. Crisp visuals pair nicely with superb colors right out of the box to deliver a stunning visual experience. The Nano IPS technology at the heart of this 240Hz monitor allows for richer, more immersive color reproduction. It features a 95% DCI-P3 color gamut and a 600 nit peak brightness – allowing it to deliver pretty good HDR performance too.

As far as gaming is concerned, the 1ms ‘true’ response time that Alienware boast isn’t far from the truth. You won’t be experiencing any smearing or ghosting issues, with overshoot limited when using the monitor’s built-in overdrive settings. Aesthetically, Alienware has smashed it out of the park with this particular brand of panels. With subtle RGB on the rear contrasting nicely with a snow-grey color scheme, it’s hard to find any negatives with this particular panel, especially with a kinder price tag than its predecessor.

The Corsair Xeneon Flex is easily one of the best options if you’re looking for a 240Hz 1440p HDMI 2.1 display. However, its high price tag prevents it from being the overall best 1440p 240Hz monitor available. It comes to shelves for an eye-watering $2,000, but for that, you do get premium features and a bendable OLED panel that is unmatched in today’s market.

Bendable OLED display aside, what sets the Flex apart from other monitors is that it not only offers 240Hz HDMI 2.1 capability, but it also features an abundance of extras that make it a real joy to use, which we found out during our hands-on first impressions look at it. The monitor features a fully comprehensive internal dashboard that gives users the ability to customize their viewing experience. It also features VRR technology, ensuring a tear-free gaming experience when playing your favourite AAA titles.

Despite its impressive features, the Xeneon Flex’s price tag still makes it a tough purchase to make. However, for those who can afford it, the Flex provides an exceptional gaming experience.

  • G-Sync support ranging from 1Hz – 240Hz
  • Very low input lag
  • Excellent picture clarity thanks to a high pixel density
  • Complete ergonomics
  • Quite expensive
  • Lacks some game-tailored OSD features

Another top selection is the ASUS ROG SWIFT PG279QM – another stunning 1440p 240Hz gaming monitor. In many ways, the ROG SWIFT is very similar to our top pick – however, due to its poor HDR performance, lack of local dimming, and low peak brightness, it falls just short of the mark.

As you’d expect, the ROG SWIFT is aesthetically flawless. ASUS always provides stunning monitors and the PG279QM is absolutely no different. The rear features the hallmark ASUS RGB branding that sets the scene for this panel nicely.

Looking at performance, the PG279QM doesn’t really put a foot wrong. It features a 1ms GTG response time, 1440p resolution, 240Hz refresh rate, and a wide Adobe RGB color gamut. Despite this being the case, it doesn’t offer a ‘true’ HDR experience due to lack of peak brightness and FALD. That said, when gaming this thing really does perform to a high level. We noticed little to no ghosting/smearing due to the panel’s excellent fast IPS panel. The monitor’s built-in G-Sync module helps to eliminate annoying screen tear entirely, with NVIDIA’s Reflex Latency Analyzer allowing gamers to record input lag between mouse and display.

  • Esports level refresh rate
  • Immersive 1000R Curvature
  • Extremely accurate colors and stunning picture clarity
  • Excellent VA panel contrast ratio
  • Build quality could be better

The Samsung Odyssey G7 is easily one of the market’s best VA monitors, delivering some of the best gaming performance the market has to offer. We reviewed the Samsung Odyssey G7 last summer and, once again, it did not disappoint.

Aesthetically speaking, the Odyssey G7 looks fantastic. It features a wide 1000R curved panel that, according to the Samsung marketing division, matches the curvature of your own eyeball to create better immersion and focus. Additionally, RGB can be found on the front and rear of this panel, with the rear featuring the brand’s famous vortex styling.

Design aside, it’s the performance that made this monitor so desirable. At the center of this monitor lies an incredibly capable VA panel that seems to have solved some of the smearing issues that are so frequent with VA technology. It delivers excellent gaming performance overall thanks to a quick 1ms response time and excellent color right out of the box. With HDR600 certification, the Odyssey G7 provides an OK HDR experience. However, with only edge-lit dimming, it is by no means the best HDR monitor we’ve tested.

That said, take nothing away from this panel, it offers all the features and specifications you could want for a truly immersive gaming experience.

  • Full G-Sync support

  • Fast 1ms response time (GTG)
  • NVIDIA Reflex analyzer
  • Build quality could be better
  • Ergonomics are lacking

ViewSonic probably aren’t the first brand you’ll think of when it comes to high-end gaming monitors, but maybe they should be. The XG271QG is a fine example of the high-end performance that the brand’s displays can offer.

Aesthetically, the ViewSonic isn’t the best monitor we’ve ever seen. It offers a fairly basic stand and limited design features throughout. However, that isn’t necessarily a bad thing – with many preferring a subtle design over something more elaborate.

Design aside, performance is where this monitor really stands up. The XG271QG is part of the brand’s ELITE series – meaning it features only the best performance they offer. At the heart of this monitor lies a very cable ‘SuperClear’ IPS panel that is certified for up to 99% Adobe RGB coverage. While this is great for editing purposes, a lack of FALD and adequate peak brightness mean the HDR performance is less than desirable.

On the plus side, a 1ms response time can be expected with limited smearing and ghosting when playing either fast-paced shooters or less competitive alternatives. G-Sync and NVIDIA’s Reflex Latency are supported by this panel, allowing gamers to eliminate screen tear and record the input lag they receive. Finally, the ELITE XG271QG features input-rich connectivity options for most people’s needs.

Samsung’s Odyssey Neo G9 is our final selection in this 1440p 240Hz guide, featuring a unique set of pros that no other panel in this guide can match. You’ll first notice it super ultrawide 32:9 aspect ratio.

If you’re only just hearing about the Samsung Odyssey Neo G9, where have you been for the last 12 months – it’s arguably one of the most desirable ultrawide monitors, well, ever. The huge 49-inch display features a stunning 1000R curvature that, like the Odyssey G7, has been designed to match the curvature of your eye for a more immersive visual experience. A white color scheme has been deployed with this particular model, making it looks even more futuristic and loud. Samsung’s Vortex can be found at the rear of the panel, finishing off what is a very impressive-looking gaming monitor.

Unlike the other options in this guide, Samsung’s Odyssey Neo G9 is the only panel that features mini LED backlight technology. This new panel technology gives the monitor true FALD (full-array local dimming) – which helps deliver stunning HDR performance. With immersive colors right out of the box and a wide color gamut, the HDR performance this monitor provides really is some of the best we’ve tested.

Colors aside, the motion handling of this monitor is also very strong. We ran several BlurBuster pursuit camera tests through this monitor and smearing/ghosting/blur was much lower than you might expect. A 1ms response time and built-in overdrive settings also allow you to tweak the performance of this panel to the exact needs.

Overall, it’s hard to knock this panel at all. If it wasn’t for the huge price tag, it’d be well up there for the best 1440p 240hz monitor in 2023.

Hardware expectations for 1440p 240Hz monitor gaming

To achieve 1440p 240Hz gaming, you will need a powerful combination of GPU and CPU. That said, your GPU is arguably the most important hardware consideration as it drives the frame rate.

So, with that in mind, you will need a high-end graphics card that can handle the demands of 1440p gaming at 240Hz. NVIDIA’s GeForce RTX 3080 or AMD’s Radeon RX 6800 XT are both excellent choices that can deliver the performance you need. As new GPUs have come along though, we’d recommend looking towards flagships such as the RTX 4090 and RX 7900 XTX for unrivalled performance.

As for the CPU, you will want a powerful processor that can keep up with your GPU – as we don’t want to experience bottlenecking. Intel’s Core i9-11900K or AMD’s Ryzen 9 5900X are both great options that can handle the demands of high-refresh-rate gaming.

It’s worth noting that, 1440p 240Hz gaming will also depend on other factors such as the game you are playing, the amount of RAM you have, and the resolution/graphical settings you plan on playing with. However, a combination of the GPU and CPU mentioned above should provide a strong foundation for achieving the high frame rates you desire in most games.

Things to consider when buying a 240Hz 1440p monitor

Like we’ve previously stated, if you aren’t up-to-speed with the latest monitor news and tech, choosing your next gaming monitor can be a little tricky. Fortunately, we’ve got a tonne of experience when it comes to display technology, meaning we have all the tools to efficiently select the market’s leading options. 

To aid in your decision-making process, we like to run over some of the more fundamental factors that must be considered when buying a 1440p 240hz monitor:

Refresh rate

Refresh rate is arguably one of the most important display specifications you can consider when buying a new panel. Refresh rate refers to how often your display refreshes the image on a screen, with higher refresh rates having a direct impact on the smoothness of your visual experience. 

For this article, all monitors offer a 240Hz refresh rate. This is one of the highest refresh rates you can get, providing an incredibly fluid experience when you’re gaming. 


The 1440p screen resolution is considered the perfect middle ground between image clarity and gaming performance. The QHD resolution measures in at 2560 x 1440 (pixels) and provides 27-inch monitors (and above) a good pixel density ratio for excellent picture clarity. 

One thing to remember when choosing a new monitor is how resolution affects gaming performance. Resolution is arguably one of the most demanding graphical options you can change, with huge dips in performance when comparing 1440p to 1080p. The same can be said when going from 1440p to 4K

Fortunately, 1440p isn’t the most demanding resolution out there and modern GPUs can run AAA games at well over 100 frames per second in this particular resolution. 

General color accuracy & color gamut (WCG)

While not hugely important, many of the monitors in this guide feature excellent color accuracy. While this isn’t a defining feature in a gaming monitor, it certainly adds value to an individual wanting a monitor for all-round usage. Color accuracy can be broken up into the following sections:

If you’re looking for a monitor that can produce good HDR quality and is accurate enough for editing purposes, you must always consider both color accuracy and gamut coverage.

Below is a test result we measured when testing the Samsung Odyssey Neo G9. As you can see, the color gamut is much wider (WCG) than the sRGB space. This is great for most users as the panel can deliver richer more realistic colors.

Of course, color accuracy often comes down to some form of factory calibration. This is at the discretion of the monitor manufacturer, with well-calibrated monitors featuring a average deltaE of <2. 

Viewing angles

The next thing we want to talk about is the viewing angle of your monitor. A wider viewing angle is preferred, as it gives you a better view of what’s on screen regardless of how you or the monitor is positioned. Great for multiple users at once for example. Additionally, this is important if you’re going to be using an ultrawide or multi-monitor setup where a screen may not be centered in front of you. IPS monitors tend to have the best viewing angles, with OLED displays joining and even overtaking them.

A wide viewing angle compliments ergonomic attributes such as height adjustment, tilt, and swivel on your monitor.

AMD FreeSync and Nvidia G-Sync

Pretty much every modern monitor for gaming will feature either AMD FreeSync or Nvidia G-Sync support. AMD FreeSync Premium Pro is a popular choice among manufacturers, while many FreeSync monitors are officially G-Sync compatible as certified by Nvidia. It no longer matters which GPU you have in your system either, so compatibility is widespread.

Both of these are Variable Refresh Rate (VRR) technologies, designed to sync your refresh rate to your GPU’s output. In other words, your in-game frames per second will sync to your monitor refresh rate. This is great for high refresh rate monitors which may otherwise suffer from screen tearing effects, compromising your gaming performance and general video quality.

Are 1440p 240Hz monitors cheap?

As monitor technology continues to evolve, we’re starting to see more 1440p 240Hz monitors hit shelves. Better yet, with the technology slowing moving towards the “aging” bracket, we’re naturally seeing prices drop on these great esports displays.

Better yet, with 1440p monitors now featuring 300Hz refresh rates, 240Hz no longer offers the pinnacle of gaming perfect to this resolution. There are also a slew of 360Hz and 500Hz monitors in the works, meaning 240Hz monitors could fall even further in price this year.

Are 1440p 240Hz monitors worth it?

With monitor technology advancing at an exponential rate, we often get asked whether or not the 1440p 240Hz monitor is still worth it.

In short, 1440p 240Hz monitors are arguably the sweet spot for both gaming and productivity-type work – offering excellent fluidity and screen real estate. Better yet, with 1440p monitors now offering up to 300Hz refresh rates – and 8K monitors on the horizon – we’re seeing a drop in price for these middle-of-the-road options, making them well worth your money.

Is a 1440p 240Hz monitor a good choice for Xbox Series X & PS5?

Both the PS5 and Xbox Series X are great consoles and ones that features the ability to push high refresh rates alongside high resolutions. With that being said, you wouldn’t want to handicap your viewing experience by choosing a 1440p 240Hz monitor when using the Xbox Series X or PS5. Instead, we’d recommend choosing one of the best 4K gaming monitors or one of the market’s best HDMI 2.1 monitors – both of which will offer you a more enjoyable viewing experience.

Is 240Hz good for competitive gaming?

While not the fastest monitors on the market, 240Hz gaming monitors are some of the quickest available today. So yes, they are ideal for competitive gaming – no doubt.

Better yet, your PC should have the ability to comfortably hold 240 frames per second when playing lesser-intensive titles – meaning you won’t run the risk of annoying lag artifacts.
