At 240Hz, fast-paced motion becomes significantly smoother as opposed to standard 60Hz-75Hz displays. Although the bump isn’t as noticeable as it’s when going from 60Hz to 144Hz, you can definitely see and feel the difference.

A higher refresh rate also ensures lower input lag! While these things won’t magically make you a better player, you do get a slight advantage over other gamers with regular screens.

Most importantly, a high refresh rate makes the gaming experience feel more responsive and enjoyable.

Now, to ensure you’re getting the optimal performance, there are additional things to consider, such as the screen size and panel type as well as VRR and MBR performance — all of which we’ll get into in the following monitor reviews.

If you want to view our changelogs for this particular buying guide, you can do so at the end of this article.

The Pros:

  • Quick response time, low input lag
  • Plenty of gaming features including FreeSync up to 240Hz
  • Fully ergonomic stand, USB hub
  • Vibrant colors and wide viewing angles

The Cons:

  • No MBR
  • IPS glow and mediocre contrast ratio (as expected from this panel technology)

About The Monitor

The Dell S2522HG is a 25″ 1080p 240Hz IPS gaming monitor that goes for $250 – $280. It’s one of the cheapest 240Hz displays yet it offers buttery-smooth performance and great image quality.

Image Quality

Thanks to its IPS panel, the Dell S2522HG has 178° wide viewing angles, meaning that the picture won’t shift in color, brightness, contrast or gamma when looked at skewed angles.

Further, the colors are accurate and consistent across the screen. The monitor covers the entire sRGB color space, so if you have a colorimeter, you can also use it for professional color-critical work involving the sRGB gamut.

Most importantly, the Dell S2522HG has a rapid 1ms GtG pixel response time speed, which ensures that there’s no visible ghosting behind fast-moving objects.

With a 400-nit peak luminance, the monitor can get more than bright enough even in particularly bright rooms, while the contrast ratio is standard for IPS technology at 1,000:1.


Moving on, the S2522HG supports AMD FreeSync with a 48-240Hz VRR (variable refresh rate) range for tear-free gameplay.

This technology synchronizes the monitor’s refresh rate with GPU’s frame rate. So, when you’re getting around 144FPS, for instance, the display will dynamically change its refresh rate to 144Hz – thus preventing tearing and stuttering at no perceptible input lag penalty.

Sadly, the S2522HG doesn’t support optional Motion Blur Reduction (MBR), which reduces perceived motion blur at a cost of picture brightness by backlight strobing.

MBR also introduces screen flickering. It’s invisible to the human eye, but those sensitive to flicker can still experience headaches or eye strain after prolonged use.

If you want a 240Hz gaming monitor with MBR, we recommend the ASUS VG259QM.

Other features include Dark Stabilizer (improves visibility in darker games) and various pre-calibrated picture presets.

Design & Connectivity

Dell S2522HG Monitor Design

The Dell S2522HG has a height-adjustable stand by up to 130mm, and you can tilt the screen by -5°/21°, pivot by 90° and swivel it by +/- 45°. Alternatively, you can mount the screen using the 100x100mm VESA pattern.

Connectivity options include two HDMI 2.0 ports, DisplayPort 1.2, a headphone jack and a quad-USB 3.0 hub.


  • ASUS VG259QM – A more expensive 25″ 1080p 240Hz 1ms IPS gaming monitor with backlight strobing (ELMB-Sync), 280Hz overclockable refresh rate and some other gaming features (such as crosshair overlays). For most people, the Dell S2522HG will do just fine because the difference between 240Hz and 280Hz is not noticeable and most users prefer not to use backlight strobing as it reduces brightness and introduces screen flickering.

The Pros:

  • Quick response time, low input lag
  • AMD FreeSync and MBR up to 240Hz
  • Impeccable MBR implementation
  • Additional gaming features including S. Switch and the shading hood
  • Fully ergonomic stand, USB hub

The Cons:

  • Inferior image quality to IPS/VA panels
  • Narrow viewing angles
  • Expensive

About The Monitor

BenQ’s Zowie gaming monitors are often the choice of professional players and various eSports tournaments; there are good reasons for that, too!


The BenQ XL2546K is based on a TN panel with inferior image quality and narrower viewing angles in comparison to IPS panels.

So, why is the XL2546K almost double the price of the Dell S2522HG?

Well, it’s mainly due to its exclusive gaming features, most importantly, the DyAc+ (Dynamic Accuracy Plus) backlight strobing technology.

This Motion Blur Reduction implementation is much better than that of most monitors. First of all, it has a minimal picture brightness toll allowing you to enjoy a bright picture quality.

Secondly, there’s minimal strobe crosstalk up to ~180Hz strobed, so there won’t be any prominent double images or other distractions.

Indeed, the XL2546K resembles CRT displays when it comes to motion clarity due to the absence of motion blur, trailing and overshoot paired with low input lag.

Other gaming features include the S. Switch device which allows you to remotely make some quick adjustments to monitor settings, Black eQualizer (improves visibility in darker scenes), FreeSync up to 240Hz and Color Vibrance (color saturation presets).

There’s also the ‘XL Setting to Share’ feature which allows for easy import/export of the monitor’s settings among users.

Design & Connectivity

The monitor is designed with professional gameplay in mind.

You get a sturdy and fully ergonomic stand (155mm height adjustment, -5°/23° tilt, +/- 45° swivel, 90° pivot and 100x100mm VESA), which takes very little desk space.

Connectivity options include three HDMI 2.0 ports, DisplayPort 1.2 and a headphone jack.


The older version of this monitor, the BenQ XL2546S, offers the same performance and features, but with a different design.

The Pros:

  • Quick response time, low input lag
  • AMD FreeSync and MBR up to 240Hz
  • Impeccable MBR implementation
  • Additional gaming features
  • Fully ergonomic stand
  • Vibrant colors and wide viewing angles

The Cons:

  • IPS glow and mediocre contrast ratio (as expected from this panel technology)

About The Monitor

The ViewSonic XG2431 was the first gaming monitor to receive the Blur Busters Approved 2.0 certification for its PureXP backlight strobing technology which implies superior performance, firmware updates and more.

Image Quality

Panel-related specifications include a 400-nit peak brightness, a static contrast ratio of 1,000:1, 8-bit color depth support, 1ms GtG response time speed and the standard sRGB color gamut.

So, you’re getting the same viewing experience as with the other ~24″ 1080p 240Hz IPS gaming monitors. It’s when we get to its impeccable MBR performance that things start to get interesting.


The ViewSonic XG2431 supports AMD FreeSync with a 48-240Hz VRR range and offers stable VRR performance with NVIDIA cards.

Other gaming features are pretty standard and include pre-calibrated picture presets and Black Stabilization (for better visibility in darker games).

Its main feature, of course, is the PureXP backlight strobing technology approved and pre-tuned by Blur Busters, who popularized and helped develop Motion Blur Reduction in gaming monitors.

Backlight strobing on 240Hz monitors is most efficient when the display is set between 100Hz and 144Hz as there’s less strobe crosstalk (double images) than at 240Hz.

Note that a 240Hz monitor will have better MBR performance at 144Hz than a 144Hz display strobing at 144Hz, so the monitor’s high refresh rate isn’t going to waste here.

Now, when you set the ViewSonic XG2431 to 120Hz, enable PureXP, and ensure you’re getting ~120FPS (either by using VSYNC or capped frame rates), you’ll get an incredible CRT-like motion clarity with no blur behind fast-moving objects.

It also supports strobing from 60Hz up to 240Hz and offers plenty of customization, allowing you to tune it just right for your preference.

What’s more, thanks to the monitor’s high peak brightness and vibrant colors, the image quality will also be excellent!

Design & Connectivity

ViewSonic XG2431 Monitor Design

The ViewSonic XG2431 has a fully ergonomic stand with up to 120mm height adjustment, -5°/15° tilt, +/- 90° swivel, 90° pivot and 100x100mm VESA mount compatibility.

Connectivity options include two HDMI 2.0 ports, DisplayPort 1.4, a headphone jack, two 3W integrated speakers and a dual-USB 3.0 hub.

The Pros:

  • High contrast ratio and strong peak brightness
  • Wide color gamut
  • Plenty of features including FreeSync and MBR up to 240Hz
  • Fully ergonomic stand and rich connectivity options

The Cons:

  • 1000R curvature too steep for some users
  • VRR Control option might cause micro-stuttering on some units

About The Monitor

The Samsung Odyssey G7 is a 1440p 240Hz display based on a curved VA panel with a high contrast ratio, wide viewing angles and vibrant colors.

It’s available as a 27″ model (Samsung C27G75T) and as a 32″ version (Samsung C32G75T).

Image Quality

On 27-inch monitors, the 1440p resolution provides a high 108 PPI pixel density, resulting in crisp details and text, plenty of screen space and no necessary scaling.

If you’re more interested in the 32-inch model, keep in mind that 1440p on 32″ monitors have the same pixel density as 24″ 1080p displays, so you’ll get the same amount of screen space and details – but because the screen is bigger, the image quality will be more immersive.

Moving on, the Samsung G7 has a high static contrast ratio of 2,500:1, which results in significantly deeper blacks in comparison to IPS and TN monitors.

Best of all, in addition to its wide 95% DCI-P3 color gamut and wide 178° viewing angles, you also get a high peak brightness of 600-nits, so the image quality is a lot more immersive.

It’s also one of the rare VA panel monitors with a rapid 1ms GtG pixel response time speed. So, you won’t get any ghosting or smearing usually associated with VA displays.


MBR is supported, but just like with all monitors mentioned in this guide (except for the ViewSonic XG2431 and the BenQ XL2546K), the strobing is not well optimized as the overdrive is locked to ‘Fastest’ which is the most aggressive mode.

So, unless you can maintain consistent 240FPS, you’ll get double images with fast-moving content.

Regardless, its GtG performance is very good, so you don’t have to rely on MBR for smooth gameplay.

The Samsung G7 has AMD’s FreeSync Premium Pro as well as NVIDIA’s G-SYNC Compatible certifications.

Other features include the standard gaming utilities such as custom crosshairs, pre-calibrated picture presets and Black Equalizer for better visibility in darker games.

The design of the monitor includes a very aggressive 1000R screen curvature for added immersion while the stand is sturdy and offers a good range of ergonomics including up to 120mm height adjustment, +/- 15° swivel, -9°/13° tilt, 90° pivot and 100x100mm VESA mount compatibility.

In order to reach 240Hz at 2560×1440 with 10-bit color, you will need a graphics card that supports DisplayPort 1.4 with DSC (Display Stream Compression) such as AMD’s RX 5xxx or NVIDIA’s GTX 16xx and RTX 20xx series or newer.

If you have an older graphics card, you’ll still be able to reach 240Hz at 1440p, but only with 8-bit color depth. You can also drop the refresh rate to 144Hz for 10-bit color.

Connectivity options include two DisplayPort 1.4 ports, an HDMI 2.0 port (max 144Hz), a headphone jack and a dual-USB 3.0 hub.

The Pros:

  • Quick response time, low input lag
  • Plenty of features, including FreeSync and ELMB-Sync up to 270Hz
  • Fully ergonomic stand and rich connectivity options
  • Adobe RGB gamut, high pixel density

The Cons:

  • IPS glow and inferior contrast ratio to that of VA panels

About The Monitor

If you’d rather have a flat-screen 1440p 240Hz gaming monitor, check out the ASUS ROG Strix XG27AQM!

Image Quality

The XG27AQM uses a quantum-dot enhanced IPS panel by AUO with a wide 99% Adobe RGB gamut (~150% sRGB) for lifelike colors. There’s also a ~100% sRGB clamp, should you wish to view SDR content with accurate colors.

While the ASUS model offers punchier colors than the Samsung G7, it has a notably lower 1,000:1 contrast ratio, so blacks won’t be as deep.

Further, it has a lower 400-nit peak brightness, which is more than enough for SDR content, but the HDR viewing experience is not as immersive. The XG27AQM has VESA’s entry-level DisplayHDR 400 certification.


The 1ms pixel response time speed efficiently eliminates all trailing behind fast-moving objects.

You can even overclock the monitor up to 270Hz, and use FreeSync/G-SYNC Compatible for tear-free gameplay up to 270FPS.

There’s also a backlight strobing technology called ELMB-Sync available that allows you to use VRR and MBR at the same time.

Other features include various picture presets, Shadow Boost, a refresh rate tracker, RGB lighting and on-screen crosshairs.

So, which one should you choose between the ASUS XG27AQM and the Samsung C27G75T? The most obvious difference is flat vs curved screen, which comes down to personal preference.

The XG27AQM has more vibrant and consistent colors, wider viewing angles and smooth VRR performance with a well-implemented optional backlight strobing technology.

The Odyssey G7 has a higher contrast ratio for deeper blacks and no IPS glow, but due to the narrower viewing angles, some gamma/saturation shifts can be detected when watching the screen at certain angles. Further, variable refresh rate can introduce some micro-stuttering, depending on the game and frame rate.

Design & Connectivity

  • Fully ergonomic stand and rich connectivity options
  • Adobe RGB gamut

The Cons:

  • IPS glow and inferior contrast ratio to that of VA panels

About The Monitor

Want a 1440p 240Hz gaming monitor with a 32″ flat-screen panel? The Acer Predator XB323UGX is for you!

Image Quality

The XB323UGX is more or less a 32″ variant of the previously mentioned XG27AQM with a few important differences.

To start with, the 1440p resolution results in a lower pixel density on 32″ sized screens, so the image won’t be as sharp on the XB323UGX, but the bigger screen can offer a more immersive gaming experience.

Next, the XB323UGX has VESA’s DisplayHDR 600 certification, so the HDR image quality is a bit better as you get a higher 600-nit peak brightness and 16 dimming zones.


Variable refresh rate is supported with both AMD’s FreeSync Premium and NVIDIA’s G-SYNC Compatible certification within the 48-240Hz dynamic range. You can overclock the monitor up to 270Hz, but in that case, you cannot use VRR.

Unlike the XG27AQM, the XB323UGX does not support Motion Blur Reduction. It has other common gaming features, such as Black Boost and crosshair overlays.
