The Best 120hz Gaming Monitor for PC available in 2021


It might be hard to select the proper game monitor. Although many accessories such as a mouse, gamepads, and keyboards are mostly personal preferences, certain Gaming Monitors provide greater resolutions, quicker refresh rates, or precise colors. Monitors may last a long time too – frequently five or more years – and every day you will most likely utilize them, whether you’re playing games or attempting to do some work.

Gaming has changed over the last several years, offering new 4k screens a more vivid experience in gaming. Both consoles and PC gamers have adopted this new format with mid-cycle updated consoles to use these new displays’ higher levels of detail. However, this is not without compromises, as most 4k panels have a sluggish rate of refresh and, by implication, longer reaction times than their counterparts with a lesser resolution.

Are you doubtful why the greatest 120Hz monitor is required? See this way. See it. Do you believe you’ll get the finest experience if the monitor delivers blurring pictures if you’re an ardent player and rapid action games are your type of thing? You’re also a fan of the Xbox One X game consoles?

So, you’re looking for the best 120Hz monitor, right? As the monitors are not the cheapest, we have a list of gaming monitors that you won’t regret buying in 2021. Also, you can see the best gaming to buy in 2021 – Get the most out of your gaming

What Is a 120Hz Monitor?

A 120Hz monitor has a 120Hz refreshing rate, which allows smooth visual results to be obtained. This would offer a wonderful effect if anything was displayed on such a monitor. Also, you can see that – Why Did The PlayStation 5 Fail To WOW Gamers?

So what is the meaning of the word ‘cooling rate?’ Well! In other words, it’s the period for a display to update in a second. The only purpose for a refresh rate is the production of a new frame every second, which at the end of the day offers outstanding image quality.

One of the main reasons to buy the cheapest 120 Hz displays is that the display is quick and delivers superb results every second. Every picture or visually shown on the monitor is updated 120 times every second. When you do math, it implies that the visual will be refreshed around 7200 times in one minute. So you can picture the strength of the visual?

Now that you know what the real goals of the 120Hz monitors are, let’s proceed towards 120Hz, the best monitors of 2021, with amazing quality as well.

Alienware AW2521HF:

Except for its modern Nano IPS panel, which combines the traditional IPS strengths – broad viewing angles and good color accuracy – with high rates of refreshment, quick pixel reaction times, and low input lag you would usually associate with TN Panel Monitors, the Alienware AW2521HF is by and large the highest 240Hz monitor we have tested. Also, you can see a true Gamer’s Take on the Sony PlayStation 5: Exclusive Review

The AW2521HF is therefore ideal for competitive matches at rapid rates like CSGO, Valiant, and Call of Duty Warzone while being a fantastic option to slow down and watch films. VRR is also supported for AMD and Xbox users with FreeSync, and Nvidia cards G-Sync compatible users. You will feel the increased response when you move to a 240Hz model like this one if you are currently using a 60Hz, 120Hz, or 144Hz monitor.

Its brightness and contrast, which may turn black tone grey, and its absence of HDR compatibility, is the only significant drawback to this monitor. But neither of these are important concerns for competitive gaming, which is what this display wants, and owing to the color precision, grey homogeneity, and broad viewing angles of this panel, SDR material appears excellent.

Key Features:

Screen Size34.1 inches
Screen Resolution3440 x 1440 pixels
Refresh Rate120 Hz
Weight37.4 lbs (16.96 kg)
Dimensions (L x W x H)20.71 x 21.9 x 9.92 inches


  • Extremely fast reaction time
  • The construction quality is excellent
  • Viewing angles are broad


  • Black homogeneity isn’t up to standard
  • There is no support for HDR

LG 27GP950:

For consoles and pcs alike, the LG 27GP950 is the best 4K 144Hz monitor. It supports both the 4K 120Hz gameplayer support HDMI 2.1 for Xbox X and PS5 series, and a 1.4 DSC DisplayPort connection to achieve the 4K 160 Hz on a single cable on your PC. The quick Nano IPS display is perfect for high-faith and productive games, helped by a huge variety of colors and outstanding color precision, while the high refresh rate and rapid pixel reaction times guarantee that fast-moving games seem fluid, with little input delay. Also, you can see the best gaming monitors to buy in 2021

The 27GP950 outperforms other 4K 144Hz monitors at its price point with Display HDR 600 support, which means the screen can exceed 600 nits of brightness for HDR highlights. This standard is where HDR starts to feel more worthwhile, so it’s great to see it here. The display is also FreeSync/G-Sync Compatible, so you’ll have variable refresh rates between 48 and 160 Hz to smooth out uneven frame rates and eliminate tearing/judder.

Key Features:

Screen Size34.1 inches
Screen Resolution3840 x 2160 pixels
Refresh Rate120 Hz
WeightWall Mount
Dimensions (L x W x H)20.71 x 21.9 x 9.92 inches


  • Input latency is quite minimal
  • Support for FreeSync as well as G-SYNC compatibility
  • Exceptional response time


  • The contrast ratio is low

Asus XG438Q:

It is a reveal of the Asus XG438Q. This 43″ display supports 4K at 120Hz with Display HDR 600 via DisplayPort 1.4, making it ideal both for slow-run and fast-runner games with a lot of candy. There is an appropriate monitor and not a TV, which makes the entry lag incredibly low and allows you to see opponents in corners by using all the normal genre-specificities and game-oriented features.

The Asus monitor is 43 inches highly appropriate for tiny living rooms, and may also be used on a workstation if you can sit down a bit. The enormous screen size implies 100 or 125% scales in Windows may be avoided, as compared with the smaller 4K screens that need 150% or greater scaling, so that the huge amount of screen-based property 4K gives can truly be used.

The XG438Q utilizes a VA panel with known strengths and limitations. Contrast is outstanding, at 4000:1, and the maximum brightness is high by six hundred nits so that both the dark and the brilliant highlights are effectively represented in HDR material. With 90% of the DCI P3 gamut covered, color precision also constitutes a strength. For color-sensitive activities such as video editing, this monitor makes it a sensible choice with only the most current IPS or OLED panels giving a superior experience. The only significant inconvenience is the intermediate motion resolution – the claimed GtG pixel reaction time of 4ms may occasionally make the action quicker – and the view angle is poor. There is no HDMI 2.1 here too, which prevents next-gen consoles from benefiting from the greater refresh rate on this panel. Although this restriction is taken into account, the Asus ROG Strix XG438 remains an excellent choice – particularly because fewer displays, such as the Predator X27P, frequently cost much more!

The difference between 60hz and 120hz is pretty considerable. It is particularly useful for FPS games. The difference is instantly obvious when the two screens are positioned in front of you. Furthermore, it will not be possible to ghost 120hz, but remember that it should have an input latency of 3-5ms and a 1ms reaction time.
It's quite incredible. You will not have any trouble pulling up high frame rates to make the GTX 770 genuinely smooth. Maybe you want to investigate IPS panels if you decide against 120hz. Moreover, "our eyes can't tell between 60hz and 120hz." It is not accurate.
  1. Alienware AW2521HF
  2. Asus XG438Q
  3. LG 24ML600M-B
On a 144 Hz monitor, a new picture appears every 7 milliseconds; on a 120 Hz monitor, it appears every 8 milliseconds; and on a 60 Hz monitor, it appears every 16 milliseconds. As a result, while the 144hz refresh rate is greater than 120hz, upgrading from a 120 to a 144 screen may not be beneficial. However, I would argue that there is no reason not to update if you are still utilizing a 60hz display.
