best 120hz gaming monitors guide that shows the top best gaming monitor model

A whopping 75% of electronic and appliance reviews are untrustworthy. That’s why every reviewer gets a Trust Rating so our True Score System filters out the fake reviews. See how we do it.

When you’re looking for the best 120Hz gaming monitors, it’s crucial to focus on image quality, response time, and input lag. These monitors should deliver excellent brightness, accurate color gamut, and a contrast ratio over 1000:1. A low response time reduces motion blur, enhancing gameplay, while low input lag ensures your actions translate immediately on screen.

In our analysis, four gaming monitors excelled. We examined 196 models, certified them as tested, and reviewed 320,848 customer reviews. Unfortunately, 71% of expert reviews weren’t trustworthy. Using True Score and Trust Score, we filtered out the fake and low quality reviews to spotlight the top performers. These monitors offer smooth, responsive gameplay, making them the best choices for gamers.

For even faster refresh rates, the best 240Hz gaming monitors deliver unmatched responsiveness for competitive gamers, while 144Hz gaming monitors offer a sweet spot between smoothness and cost-effectiveness. Additionally, these great monitors balance performance and features to cater to different needs and preferences.

Which Criteria Matters for Testing 120Hz 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!

CRITERIARANGEREQUIREDDEFINITION
Contrast Ratio>1300:1YesThe 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 1300:1, 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. When choosing a top-rated gaming monitor, consider a high contrast ratio to ensure dynamic visuals and immersive gameplay.

Contrast Ratio (higher is better)

2. 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, such as using the monitor vertically for coding, so it can be safely ignored if you don’t plan on gaming on your monitor.

Input Lag (in ms; lower is better)

3. 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 90% 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. The best HDR monitors typically cover a significant portion of the DCI P3 gamut, ensuring vivid and accurate colors for an optimal viewing experience.

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

Best 120Hz Gaming Monitors: Mistakes To Avoid

  1. Assuming Higher Refresh Rate Means Better: While a higher refresh rate can improve gaming smoothness, it’s not the only factor to consider. Other aspects, such as response time, panel type, and resolution, also play significant roles in overall performance. For example, when comparing 144Hz vs 75Hz gaming monitors, it’s important to understand that the higher refresh rate provides smoother visuals. Still, the overall gaming experience depends on how well other features, such as response time and resolution, meet your specific needs.

  2. Ignoring Panel Type and Response Time: Just like with 144Hz monitors, the panel type (TN, IPS, VA) and response time are crucial factors. TN panels typically offer the fastest response times but may sacrifice color accuracy and viewing angles compared to IPS or VA panels. Understanding refresh rate vs response time is important for gaming.

  3. Not Considering Resolution: While 120Hz monitors are often available in various resolutions, such as 1080p (Full HD), 1440p (QHD), and even 4K, choose a resolution that matches your graphics card’s capabilities and gaming preferences. The best 1080p gaming monitor offers a smooth gaming experience with higher refresh rates, ideal for competitive gaming on budget systems. For a more detailed and immersive experience, the top 4K gaming monitor delivers ultra-high resolution, which is perfect for gamers who prioritize visual fidelity and have powerful graphics cards.

  4. Overlooking Adaptive Sync Technology: Adaptive Sync technologies like AMD FreeSync and NVIDIA G-Sync can prevent screen tearing and stuttering, providing a smoother gaming experience. Ensure your monitor supports the adaptive sync technology compatible with your GPU. This can also help reduce issues such as a flickering monitor while gaming, which can occur due to synchronization problems between the monitor and the GPU.
