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! Although 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.

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.

Acer XF250Q - Cheapest 240Hz Monitor

acer xf250q monitor

About the Monitor

The Acer XF250Q is the most affordable 240Hz gaming monitor yet it offers everything you need for a buttery-smooth competitive fast-paced gaming experience.

Image Quality

Just like most 240Hz monitors, the Acer XF250Q is based on a TN (Twisted Nematic) panel, which offers a very fast 1ms GtG pixel response time speed for minimal motion blur and visible trailing behind fast-moving objects.

However, TN panels also have inferior image quality and viewing angles in comparison to IPS and VA panels.

VA panel monitors have the slowest response time speed, which causes visible smearing in fast-paced games, so we don’t recommend them for competitive first-person shooters (excluding some of the newer high-end models).

Some IPS monitors are just as fast as TNs – plus, they have excellent colors and wide viewing angles – but they are more expensive. So, if you’re looking for something under $300, the Acer XF250Q is your best bet for FPS games.

It has a peak brightness of 400-nits, which will ensure a bright picture even in well-lit rooms. Other specs include a 1,000:1 contrast ratio, dithered 8-bit color depth, and 1080p resolution – all of which is standard at this price range.

On the 24.5″ viewable screen of the Acer XF250Q, 1080p resolution results in a decent pixel density of 90 PPI (pixels per inch), which translates to a respectable amount of screen space and detail clarity.

In contrast, on 27″ monitors, 1080p resolution has a pixel density of ~81 PPI, which results in a more pixelated image quality. That’s why most gamers prefer 24″-25″ sized monitors for 1920×1080.

Furthermore, 1080p is not as demanding as 1440p or 4K, which will allow you to reach 240FPS more easily to take full advantage of the monitor’s maximum refresh rate.

Besides inferior picture quality, TN panels have another big disadvantage – viewing angles.

The viewing angles are 160° vertically and 170° horizontally, meaning that the picture will change in colors, contrast, and brightness when you look at the screen off-axis. As long as you’re in front of the screen, this won’t be an issue.


freesync and gsync

Even though it’s a budget monitor, the Acer XF250Q is actually certified by NVIDIA as ‘G-SYNC Compatible,’ which ensures flawless VRR (variable refresh rate) performance with compatible NVIDIA GPUs as well as AMD’s.

The Acer XF250Q VRR/FreeSync range amounts to 48-240Hz. As long as your FPS (Frames Per Second) rate is within this range, there will be no screen tearing or stuttering whatsoever with minimal (~1ms) input lag penalty.

In order to minimize the input lag introduced by VRR, cap the in-game FPS rate by -3FPS (237 FPS). This will prevent VSync induced input lag, which would take over G-SYNC at 240FPS+.

Alternatively, you may want to disable FreeSync and play with uncapped frame rates. This way, you get slightly lower input lag, but you will get screen tearing, which is hardly visible at high FPS/Hz anyway.

There’s no obviously better option here. It depends on user preference, video game, and the FPS rate you can maintain.

Other gaming features of the Acer XF250Q include Black Boost (improves visibility of objects in shadows) and customizable crosshair overlays.

Design & Connectivity

The build quality of the monitor isn’t very good which is expected given the price, but it will get the job done and you even get a good range of ergonomics including up to 150mm height adjustment, VESA, tilt, 90° pivot, and +/- 60° swivel.

Connectivity options include HDMI 1.4, HDMI 2.0, DisplayPort 1.2, dual 2W built-in speakers, and a headphones jack.


In case the Acer XF250Q is not available, check out the Acer KG251Q which is another budget-friendly 240Hz model.

Keep in mind that there are different variants of the KG251Q, so make sure you get the 240Hz model – the Acer KG251Q Dbmiipx.

The Pros:

  • Quick response time and low input lag
  • AMD FreeSync up to 240Hz
  • Additional gaming features
  • Fully ergonomic stand

The Cons:

  • Inferior image quality to IPS
  • Narrow viewing angles

Acer XF252Q - Best Value 240Hz Monitor

acer xf252q monitor

About the Monitor

Next up, we have the Acer XF252Q which offers a bit better performance with a faster response time speed.

Image Quality

The XF252Q monitor is based on a newer 24.5″ TN panel, which has a quoted pixel response time speed 0.5ms, which Acer claims is even capable of reaching 0.3ms!

These specified response time measures don’t mean much as they indicate the fastest pixel transition the monitor can achieve under specific testing conditions; its not the average measure.

In any case, the XF252Q is actually faster than the XF250Q, but the difference isn’t all that big. If you already have a 240Hz 1ms monitor, it’s not worth upgrading just for the response time bump alone.

If you’re buying your first 240Hz display, you might as well go with the faster one.

As far as image quality goes, there are no big changes here. You get the same 400-nit peak brightness, 1,000:1 contrast ratio, and 8-bit color depth.

The XF252Q also supports HDR (High Dynamic Range), but it can only accept and display the HDR10 signal, it doesn’t have the required display capabilities to really enhance the HDR picture quality.

This is the case with all 240Hz monitors currently available. So, you can just ignore their ‘HDR support’ as it doesn’t really improve the viewing experience nor does it increase the monitor’s price.


visual response boost monitor feature

Now, the Acer XF252Q doesn’t carry NVIDIA’s ‘G-SYNC Compatible’ badge, but FreeSync will work with compatible NVIDIA graphics cards without any issues. The only difference is that you’ll have to enable it manually in the drivers.

First, enable FreeSync in your monitor’s OSD (On-Screen Display) menu, then go to NVIDIA Control Panel ->
‘Set up G-SYNC’ -> ‘Enable G-SYNC’ and you’re good to go.

Unlike the Acer XF250Q, the XF252Q supports backlight strobing via its Visual Response Boost (VRB) technology.

Backlight strobing further reduces the perceived trailing and motion blur, thus providing even smoother motion clarity, but it decreases the monitor’s maximum brightness in the process.

Luckily, the Acer XF252Q is more than bright enough when VRB is enabled, and you can adjust the strobing intensity with two different modes: Normal and Extreme.

Using the Normal mode, the picture will be brighter, but the motion won’t be as smooth as with the Extreme mode, which has a heftier toll on the brightness.

The monitor can only strobe at 120Hz, 144Hz, and 240Hz fixed refresh rate meaning that you can’t use it at the same time as VRR, which is the case for most gaming monitors that offer both VRR and MBR.

Design & Connectivity

The stand of the Acer XF252Q 240Hz gaming monitor offers full ergonomic support with up to 120mm height adjustment, 360° swivel, 90° pivot, -5°/20° tilt, and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.2, two HDMI 2.0 ports, a quad-USB 3.0 hub (2 downstream ports at the side, and 2 extra downstream + 1 upstream at the back, a headphones jack, and two 2W integrated speakers. 


All in all, if you don’t care for the downsides of the TN technology regarding viewing angles and image quality, the Acer XF252Q is the fastest gaming monitor you can get right now.

There’s also the BenQ ZOWIE XL2546S based on the same panel, but without FreeSync support. It boasts the DyAc+ (Dynamic Accuracy Plus) backlight strobing technology with impeccable performance.

This is a $500+ gaming monitor, and considering it’s a 1080p TN display, it’s only intended for professional gamers.

So, if you have ambitious goals and don’t mind paying premium for performance at the cost of picture quality, then, and only then, it’s worth considering.

The Pros:

  • Quick response time and low input lag
  • AMD FreeSync and MBR up to 240Hz
  • Additional gaming features
  • Fully ergonomic stand

The Cons:

  • Inferior image quality to IPS
  • Narrow viewing angles

ASUS VG259QM - Affordable 240Hz IPS Monitor

asus vg259qm

About the Monitor

The ASUS VG259QM allows you to enjoy the responsiveness of 240Hz as well as vibrant colors and wide viewing angles! It’s also overclockable to 280Hz for a slight boost in motion clarity!

Image Quality

On paper, the ASUS VG259QM may seem very similar to the Acer XF250Q/XF252Q; it has the same peak brightness of 400-nits, a contrast ratio of 1,000:1, and 1080p resolution.

However, thanks to its IPS panel, the colors are more accurate, consistent, and vivid! Plus, with the wide 178° viewing angles, the image will stay perfect at basically any angle.

Technically, the ASUS VG259QM is not as fast as the Acer XF252Q as there are some minor ghosting and overshoot visible in certain scenarios. Still, for most gamers, this will be completely negligible.

Of course, if you prefer performance over image quality, the Acer XF252Q is the better option for you whereas the ASUS VG259QM is more suited for those who enjoy competitive gaming as well as more graphically-oriented games.

When properly calibrated, you can even use the ASUS VG259QM for entry-level color-critical work.


Moving on, the monitor supports AMD FreeSync with a 48-280Hz VRR range, and NVIDIA certifies it as G-SYNC compatible. It also has a backlight strobing technology called ELMB-Sync, which can operate at up to 280Hz.

ASUS’ exclusive ELMB-Sync technology can also work at the same time as FreeSync/G-SYNC Compatible. However, it’s not very effective as the monitor’s overdrive setting is locked and too aggressive for the optimal performance. 

Other features include Shadow Boost (improves visibility in darker games), pre-calibrated picture presets, and custom crosshairs. For more information, visit our ASUS VG259QM review.

Design & Connectivity

The ASUS VG259QM has a height-adjustable stand by up to 130mm, and you can tilt the screen by -5°/20° or pivot/swivel it by +/- 90°. Alternatively, you can mount the screen using the 100x100mm VESA pattern.

Connectivity options include two HDMI 2.0 ports, DisplayPort 1.2, a headphones jack, and two 2W speakers.


Alternatively, you may be interested in the Dell AW2521HF, a more affordable 240Hz IPS model without overclocking and Motion Blur Reduction.

The Pros:

  • Quick response time and low input lag
  • AMD FreeSync and MBR up to 280Hz
  • Additional gaming features
  • Fully ergonomic stand
  • Vibrant colors and wide viewing angles

The Cons:

  • Disappointing ELMB-Sync performance

ViewSonic XG270 - Best Motion Clarity

Viewsonic Elite Xg270

About the Monitor

The ViewSonic XG270 is the first (and the only at the moment) gaming monitor to receive the Blur Busters Approved certification for its PureXP backlight strobing technology which implies superior performance, firmware updates, and more.

Image Quality

Now, this 27″ sized monitor has a screen resolution of 1920×1080, which, as we already mentioned, results in a low pixel density that will make the picture quality appear a bit pixelated. Sadly, the XG270 is not available as a ~24″ variant.

To reduce the pixelated appearance, you can simply sit a bit further from the screen to make individual pixels less distinguishable, or you can apply some anti-aliasing in video games.

Some users even prefer such low pixel density as bigger pixels help them with precision in FPS games.

Overall, 27″ 1080p monitors are okay for gaming, watching videos, and similar use, but if you want to use the monitor for office-related and similar tasks as well, you may find yourself lacking screen real estate and details clarity.

Other than that, panel-related specifications are the same as with the other monitors in this guide and include a 400-nit peak brightness and a static contrast ratio of 1,000:1.


The ViewSonic XG270 supports AMD FreeSync with a 48-240Hz VRR range and certified G-SYNC compatibility.

Other gaming features are pretty standard and include customizable crosshairs, pre-calibrated picture presets, Black Stabilization (for better visibility in darker games), and advanced picture adjustment tools such as six gamma presets.

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 to 100Hz – 144Hz as there’s less strobe crosstalk (double images) than at 240Hz.

Note that a 240Hz monitor will have better MBR performance at 120Hz than a 144Hz or 120Hz display that’s also strobing at 120Hz, so the monitor’s high refresh rate isn’t going to waste here.

When you set the ViewSonic XG270 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.

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

Viewsonic Xg270 Back

The ViewSonic XG270 has a fully ergonomic stand with up to 120mm height adjustment, -5°/20° tilt, +/- 90° swivel, 90° pivot, and 100x100mm VESA mount compatibility. It also has a headphones hook, a mouse bungee, and sight shields.

Connectivity options include two HDMI 2.0 ports, DisplayPort 1.2, a headphones jack, and 4 USB 3.0 ports (1 upstream + 3 downstream). There’s also customizable RGB lighting at the back of the monitor.

The Pros:

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

The Cons:

  • Low pixel density

HP Omen X 27 - 1440p & 240Hz!

hp omen x 27

About the Monitor

The HP Omen X 27 provides a 240Hz refresh rate at 1440p for a much crispier picture quality and more screen real estate, but it’s quite expensive and requires a lot of GPU and CPU power.

Image Quality

Based on a 27″ TN panel with a 2560×1440 screen resolution, the HP Omen X 27 hits the pixel density sweet spot of ~ 109 PPI meaning that you get vivid details and plenty of screen space without any scaling necessary!

Now, hitting 240FPS at 1440p will require a high-end PC system, and you will only be able to maintain such a high frame rate in competitive titles such as Overwatch, Rocket League, etc.

In the more demanding AAA titles, you will more likely sit around 100FPS – 144FPS.

An upside to this is that due to the high resolution, you won’t need to use anti-aliasing, which will save you on some GPU power.

Moving on, the HP Omen X 27 has a wide 90% DCI-P3 color gamut, and the colors are actually quite good and accurate, considering it’s a TN panel display. However, you still get the narrow 160°/170° viewing angles.

It also supports HDR, which boosts its typical 300-nit peak brightness up to 400-nits, and there are even 16 dimming zones for increased contrast ratio.

While this does offer a slightly better HDR image quality in comparison to SDR, blacks will still be grayish due to the generally low contrast ratio of the monitor, which ranges from 800:1 to 1000:1.

The monitor’s rapid pixel response time of 1ms GtG effectively eliminates motion blur and ghosting without adding any overshoot (i.e., inverse ghosting).

Overall, if you have the required PC specs to run your favorite games at ~240FPS, and you’ve outgrown the 1080p resolution, this is the monitor for you.

However, consider waiting for the 27″ 1440p 240Hz IPS models, which will have even better colors and contrast as well as wider viewing angles while their pixel response time speed should be just as fast.


The HP Omen X 27 supports AMD FreeSync 2 (FreeSync Premium Pro) with a 48-240Hz dynamic range, and it provides stable G-SYNC performance even though it’s not certified by NVIDIA.

Other features include custom crosshairs, pre-calibrated picture presets, and customizable RGB LED lighting.

Note that the monitor uses PWM (Pulse-Width Modulation) to regulate brightness at lower backlight levels which introduces screen flicker.

Although the flicker is invisible to the human eye, those extremely sensitive to it may experience headaches after prolonged use.

Design & Connectivity

Hp Omen X27 back

The stand of the monitor offers height adjustment up to 130mm, tilt by -3°/23°, and 100x100mm VESA mount compatibility using the provided adapter. You cannot swivel the screen left/right or rotate it into the portrait position.

Connectivity options include one HDMI 2.0 (max 1440p 144Hz or 1080p 240Hz), DisplayPort 1.4 (for 1440p 240Hz), a dual-USB 3.0 hub, and a headphones jack.

The Pros:

  • Quick response time and low input lag
  • AMD FreeSync up to 240Hz
  • Additional gaming features
  • Height-adjustable stand
  • Good colors for a TN panel

The Cons:

  • Expensive
  • Narrow viewing angles
  • Design lacks swivel/pivot options
  • Not a flicker-free backlight

Samsung G7 - 1440p 240Hz & High Contrast Ratio!

samsung odyssey g7 monitor

About the Monitor

The Samsung Odyssey G7 is another 1440p 240Hz display, but it’s based on a curved VA panel with a much higher contrast ratio, wider viewing angles, and better colors.

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

Image Quality

The Samsung G7 has a high static contrast ratio of 2,500:1, which results in significantly deeper blacks in comparison to the HP Omen X 27 monitor.

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

Now, although the Samsung G7 has a 1ms GtG response time speed specified just as the Omen X 27, its pixel transition speed is technically not quite as fast.

Some transitions from dark pixels into brighter shades will not be made in time with the 240Hz refresh rate, but this isn’t really noticeable in video games unless you’re really looking for it.

In fact, the G7 is on par with the fastest 144Hz IPS models available such as the LG 27GL850, so unless you’re a professional gamer where every millisecond counts, the Samsung G7 will do just fine.


MBR is supported, but just like with all monitors mentioned in this guide (except for the ViewSonic XG270 and the BenQ XL2546S), 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, but some units have noticeable brightness flickering when VRR is enabled, which is common for VA panel monitors.

This issue doesn’t affect all units of the monitor, and it’s not necessarily visible in all games. It mostly occurs when your FPS rate fluctuates a lot or reaches the LFC threshold (80FPS) of the 80-240Hz VRR range.

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

For more information, check out our Samsung Odyssey G7 review.

Design & Connectivity

samsung c32g75t monitor

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 headphones jack, and a dual-USB 3.0 hub.


Considering that the 27″ Odyssey G7 is only $50 more expensive than the HP Omen X 27, it definitely offers better value for the money as you get a much better image quality while the performance is very similar.

Of course, if you want the fastest pixel transition you can get as well as better FreeSync/G-SYNC performance, and you don’t want a curved screen, the HP Omen X 27 is the best option for you until the IPS models are released.

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:

  • Some units are affected with VRR brightness flickering with FPS fluctuations and/or at LFC threshold

Samsung G9 - 49" 5120x1440 240Hz Gaming Monitor

samsung c49g95t monitor

About the Monitor

In case you want the most immersive gaming experience possible while at the same time keeping the fluidity of 240Hz, there’s the Samsung Odyssey C49G95T.

Image Quality

This behemoth of a monitor has a 49″ sized screen with a 5120×1440 Dual Quad HD resolution. That’s equivalent to two 27″ 1440p monitors side by side, but without the gap in-between them!

Just like the G7 series, the Samsung G9 is based on a VA panel with a steep 1000R curvature, 2,500:1 contrast ratio, wide 95% DCI-P3 color gamut, and rapid 1ms GtG pixel response time.

Additionally, it has a higher peak brightness of 1000-nits for even punchier highlights in HDR content.


AMD FreeSync Premium Pro is supported as well as NVIDIA’s G-SYNC Compatible mode with a 60-240Hz VRR range.

Sadly, some units are affected by the brightness flickering issue here as well. What’s more, using HDR and FreeSync/G-SYNC at the same time causes noticeable flickering on the screen.

As the official NVIDIA driver is still not available for the G9, we hope that this will be addressed shortly.

Gaming features such as custom crosshair overlays, Black Equalizer, and various picture preset are available as well.

For more information, visit our detailed Samsung Odyssey G9 review.

Design & Connectivity

You will need a GPU that supports DP 1.4 DSC to take full advantage (240Hz at 5120×1440) of the monitor. With older cards, you’ll be limited to 120Hz at 5120×1440.

The Pros:

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

The Cons:

  • Visible flickering when FreeSync/G-SYNC and HDR are enabled simultaneously
