    Our Verdict

    If you’re looking for a mid-range 240Hz gaming monitor, the Alienware AW2723DF is an exceptional choice, especially with its input lag of 8.6ms and a response time of 4.6ms. This translates to a smoother and more responsive gaming experience, where every millisecond can be the difference between victory and defeat. Coupled with a 240Hz refresh rate, this monitor is built for speed, ensuring that fast-paced games flow without a hitch.


    The Alienware AW2723DF is VRR compatible with NVIDIA G-SYNC and AMD FreeSync Premium Pro. This feature harmonizes the monitor’s refresh rate with your graphics card, effectively eliminating screen tearing and minimizing stutter. This is a critical advantage for gamers who demand seamless gameplay, particularly in graphically intensive scenarios. Furthermore, its impressive contrast ratio of 1015:1 is not far behind the Asus ROG PG27AQDM’s 1042:1, enhancing visual depth and detail and making dark scenes in games and movies more immersive.


    Additionally, with 99.60% coverage of the sRGB color gamut and a brightness of 402.8 nits, it can double as an excellent monitor for watching movies or engaging in productivity tasks that require precise color representation. However, its 7.6% reflections could be a downside in brightly lit environments, potentially affecting the viewing experience. Thus, it’s not just a gaming monitor but a comprehensive display solution that caters to various needs.


    The Alienware AW2723DF is an excellent choice for gamers who prioritize responsiveness and fluid motion in their gameplay. Its mid-range price point and impressive performance make it a compelling option for many users, from competitive gamers to multimedia enthusiasts.

Which Criteria Matters for Testing the Best 240Hz Gaming Monitors?

By focusing on these criteria (2 required, 1 nice to have), anyone can quickly and easily compare these computer monitors and how they’ll perform. This helps you make an informed decision and purchase the best gaming monitor!

Contrast Ratio>1000:1YesThe difference in brightness between the whites (lit sections) and blacks (dim or unlit sections) of a monitor panel.
Input Lag< 15 msYesThe time it takes for the monitor to register inputs from the user and process them as action.
Color Gamut (DCI P3 xy)> 85%No (Nice to have)How much of the DCI P3 xy color gamut is covered by the monitor, which helps indicate color accuracy for HDR content, which includes certain movies.

Our Trusted Data Sources

We looked at 110+ computer monitor reviewers and found that 33 are trustworthy (60%+ Trust Rating). The three we have listed below are our most trusted for computer monitors.

  1. Samuel Breton – Rtings, MuckRack
  2. Chris Eberle – Tom’s Hardware, LinkedIn
  3. Tony Hoffman – PC Mag, MuckRack

Interested in a comprehensive analysis of our data sources? We’ve got you covered. Below, you’ll find a detailed list of every computer monitor review website we’ve identified, organized by their respective Trust Ratings from highest to lowest. But we didn’t stop there. We’ve meticulously reviewed each publication and verified the data by checking whether the authors have bio links to MuckRack or LinkedIn. We’re committed to not only checking the facts but ensuring their veracity.

Computer Monitor Test Data & Results

1. Contrast Ratio (as ratio, x:1) Test Results

Contrast ratio is responsible for making images appear “dynamic” and “dramatic.” By having a good contrast ratio, a monitor is able to recreate dramatic differences between light and dark spots in scenes, images and games accurately.

At a minimum, we recommend a contrast ratio of 1000:1, as this will do a good enough job at allow for detail in dark scenes and images. If contrast ratio gets too low, the picture quality suffers, and the monitor performs worse across the board, no matter the lighting condition. By getting a monitor with a sufficiently high contrast ratio, you can ensure the picture quality doesn’t suffer, and dramatic scenes with stark shifts in lighting, whether they be in games or videos, are created as accurately as possible.

Contrast Ratio (higher is better)

2. Color Gamut/Accuracy % (DCI P3 xy) Test Results

Color gamut is responsible for making a monitor produce accurate colors when displaying a variety of content. The DCI P3 xy gamut is considered a “standard” gamut of sorts, and is used to help color grade films. Most HDR content will use this gamut at the very least (though other gamut exist) and it’s a commonly used gamut for films.

When it comes to a computer monitor, having a panel that covers at least 85% of the DCI P3 gamut means it’ll output accurate colors when watching HDR content and movies that use the gamut. If a monitor doesn’t cover enough of the gamut, it causes color inaccuracies and shifts the image quality. If you care about maintaining accuracy in the movies you watch so they look the way they were intended, this gamut needs to be properly covered.

Color Gamut P3 XY (in %; higher is better)

3. Input Lag (ms) Test Results

Input lag is more of a concern when it comes to gaming, but if you plan on using a monitor for a bit of gaming when you aren’t focused on productivity, editing or other tasks, lower values help improve responsiveness. High input lag means your actions take longer to register on the monitor, effectively introducing an artificial delay to your reactions.

It’s for this reason that we generally recommend an input lag under 15 ms. This ensures the delay that’s introduced has minimal impact on your reactions to what’s happening on screen. It’s important to note that a high input lag won’t have any real effect on anything that isn’t gaming, so it can be safely ignored if you don’t plan on gaming on your monitor.

Input Lag (in ms; lower is better)

Best 240Hz Gaming Monitors: Mistakes To Avoid

  1. Ignoring Panel Technology: Not all gaming monitors with a 240Hz refresh rate are created equal; some may use TN, IPS, or VA panels, each with its own advantages and disadvantages in terms of color accuracy, viewing angles, and response times. Be sure to choose a panel type that aligns with your gaming preferences and needs.

  2. Overlooking Adaptive Sync Compatibility: Many high-end gaming monitors offer Adaptive Sync technologies like NVIDIA G-SYNC or AMD FreeSync to reduce screen tearing and stuttering. Ensure that the monitor you choose is compatible with your graphics card to optimize your gaming experience. For compact and efficient displays, consider the best 24-inch monitors, which are often used by esports athletes. For a little more screen real estate, you might prefer the best 27-inch gaming monitors or the top 27-inch monitor for productivity. For those seeking an immersive experience, ultrawide gaming monitors offer a large screen that’s hard to beat.

  3. Underestimating Resolution: While a 240Hz refresh rate is excellent for smooth gameplay, consider whether the monitor’s resolution (such as 1080p gaming monitors, 1440p, or 4K) meets your visual preferences and gaming setup. Higher resolutions may impact performance, so strike a balance between resolution and refresh rate based on your gaming priorities. That said, if you want a higher resolution, you may want to also consider the top 144Hz monitors.

  4. Neglecting Input Lag and Response Time: Even with a high refresh rate, input lag and response time are crucial factors that affect the monitor’s responsiveness. Look for the top-rated monitors with low input lag and fast response times (typically measured in milliseconds) to minimize motion blur and ghosting during fast-paced gaming.
