The best G-Sync monitors for 2021

The best G-Sync monitor will ensure you get the smoothest gaming performance out of your Nvidia graphics card. As a technology, the dedicated Nvidia G-Sync hardware was introduced into monitors way back in 2013 and is still the best silicon for synchronising the performance of your panel with your Nvidia GPU. And, if you can find something like an Nvidia RTX 3080 or RTX 3090, then you'll be smashing out super smooth high frame rates in your favrourite games at their top settings.

But what does G-Sync mean, anyway? You've probably seen gaming monitors proudly display that they're G-Sync ready or G-Sync Compatible. G-Sync is Nvidia's frame synchronisation technology, which drops dedicated silicon into a monitor to reduce screen tearing and display stutter. Your monitor's refresh rate will synchronize with your graphics card's output to produce a much smoother gameplay experience. Of course, to take advantage of the best G-Sync monitors, you'll need an Nvidia graphics card though these are pretty elusive right now. 

If these displays seem too pricey, you could always opt for a FreeSync monitor that is G-Sync Compatible. Though even if it's not listed, a host of FreeSync monitors still place nice with Nvidia GPUs these days. FreeSync monitors tend to have lower price points as there's no dedicated silicon needed, but they can still be certified by Nvidia to work perfectly with G-Sync (that's the G-Sync Compatible check box)—and you'll get the added support for AMD's competing FreeSync technology too. The downside is that you won't get the absolute smoothest experience unless  you choose a native G-Sync display with the embedded hardware.

Something else to be aware of is that while G-Sync will work on some FreeSync monitors, the reverse isn't true—AMD's adaptive sync technology won't work on a G-Sync monitor. So if you have an AMD graphics card or are planning on getting one, then you're better off choosing from one of the best G-Sync compatible FreeSync monitors instead.

1. Asus ROG Swift PG279Q

Best G-Sync monitor for gaming at 1440p.

Screen size: 27-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 2560 x 1440 | Response time: 4ms | Refresh rate: 144 Hz (overclocks to 165 Hz) | Weight: 15.4 lbs

1440p with 144Hz refresh rate, overclockable to 165Hz
Extremely fast refresh, low input lag for an IPS screen

This isn't just the best G-Sync gaming monitor you can get your hands on, but the best gaming monitor, period. This 27-inch monitor has a 2560x1440 resolution, which is a sweet spot for high-end gaming right now: offering much more than a standard HD display, but not being as potentially draining or demanding as a 4K screen. The results are super sharp looking games that don't require a ridiculous GPU setup. Plus, you can still get the 'usual' refresh rates as standard that we're all used to, which is always a bit lacking in 4K screens (unless you have a seriously healthy budget to burn). 

As for its more practical qualities, it supports DisplayPort 1.2a as well as HDMI 1.4 (one of each). If you want the best performing screen at the highest resolution, but without the staggering price tag (see: Acer Predator X27—though that is an excellent screen too), then this is the monitor for you. It'll last you ages and get you a fast, responsive display, with a high resolution, all with that great G-Sync tech thrown in, too.

2. Alienware AW3420DW

Best curved G-Sync monitor.

Screen size: 34-inch | Panel type: IPS | Aspect ratio: 21:9 | Resolution: 3440 x 1440 | Response time: 4ms | Refresh rate: 120 Hz | Weight: 16 lbs

Brilliantly fast for a superwide monitor
Sleek design for a large monitor

A tremendous curved option, the Alienware AW3420DW, is on the more compact end of the spectrum. It is, of course, G-Sync enabled, has a 100Hz refresh rate (that can be overclocked to 120Hz), and offers up a gorgeous 34-inch diagonal with a native resolution of 3440x1440. Combined this has a tendency to give your games an epic feel, particularly third-person titles. 

Away from the cold hard specs, this is one of the monitors that wins on the design. It's sleek and impressive in its design aesthetic, with ultra-thin bezels and a stand that doesn't impose on your desk in finish or size. If you're after a super smooth and sleek G-sync monitor from a recognized manufacturer with high standards, then Alienware's screen is undoubtedly worth your consideration.

3. Asus ROG Swift PG27UQ

Best G-Sync monitor for 4K HDR gaming.

Screen size: 27-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 4ms | Refresh rate: 144 Hz | Weight: 28 pounds

Chic design
Truly excellent image quality

This is an excellent G-Sync display, packed with features and plenty of goodness, but one that does demand a high price of admission. Even so, it remains a monitor we can get behind and recommend as one of the best G-Sync monitors going. 

It is an incredibly high-specced 27-inch display that boasts a 4K resolution and support for HDR, providing some of the crispest images you’ll see on any monitor, and the inclusion of G-Sync means it’ll be as smooth as anything too—even at 144Hz. This makes this a truly beautiful screen that, providing you have the machine to make the most of it, will give you probably the best images you can get on a gaming monitor. 

Coming with the ports that you need—an HDMI 2.0 input, DisplayPort 1.4, 3.5mm audio, and two USB 3.0 ports—its only real flaw is that criminally high list price. This might cause others to look elsewhere, but if you dive into this and commit, you’ll be set for years and delighted with your purchase.

4. Acer Predator XB273K

One of the highest quality and best bang for buck G-Sync monitors.

Screen size: 27-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 4ms | Refresh rate: 120 Hz (overclocked to 144 Hz) | Connectivity: 5 x USB 3.0 | Weight: 15.9 pounds

Excellent picture quality
Great for gaming
Good menu options

Nevermind G-Sync monitors, this is one of the best monitors you can buy. Period. Housing Nvidia’s tech alongside a 4K resolution and HDR tech means that this is an absolute beast of a monitor that will give you the best of, well, everything. And by everything, we mean everything. Its 144Hz (overclocked) IPS panel is made better by Acer’s integrated VisionCare technology that will aim to protect your retinas—plus, it looks damn good. 

The Predator XB273K is one for those who want everything now and also want to future proof themselves in the years ahead. It might not have the same HDR heights that its predecessor, the X27, had, but it offers everything else for a much-reduced price tag. Therefore, the value it provides is incredible, even if it is still a rather sizeable investment.

5. Acer Predator XB321HK

Best G-Sync monitor for high-end graphics setups.

Screen size: 32-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 4ms | Refresh rate: 60 Hz | Weight: 24.9 lbs

Great size for a 4K resolution
Brilliant colors and contrasts

A common obstacle when searching for a new display—especially in the 4K panel realm—is the trade-off of a high refresh rate for a greater pixel count. Such is the case with the Acer Predator XB321HK with its relatively low refresh rate of 60Hz, the same as most 4K TVs.

The 32-inch, IPS panel, is laudably bright and clear, giving you vivid images and a large enough screen to make the most of the 3840x2160 resolution. It doesn’t have HDR, however. And while you’d probably expect that on a 4K TV, its non-appearance here is not really a problem, and only serves to keep the cost down. 

With the Predator XB321HK, Acer is offering a sublime value for a 4K G-Sync monitor. If you’re not put off by the compromise in refresh rate, this is still a great gaming G-Sync monitor that’ll be a worthy upgrade option.

6. AOC Agon AG352UCG6 Black Edition

Best superwide curved G-Sync monitor.

Screen size: 35-inch | Panel type: VA | Aspect ratio: 21:9 | Resolution: 3440 x 1440 | Response time: 4ms | Refresh rate: 120 Hz | Weight: 26 lbs

Brilliant colours and contrasts
Competitively priced

It's not unreasonable to say that for many, the sweet spot for gaming is still 1440p. Whether it's the usual 16:9 ratio or at super-wide 3440x1440, the crispness provided by that mid-ground between 1080p and 4K is ideal, providing the best way to enjoy the latest big-name games.

Mixing that super-wide resolution with some of the latest technologies, this is a quality screen worthy of consideration. It has a distinguished VA panel, a decent 4ms response time, G-Sync, and has bumped its refresh rate to 120Hz, enabling frame rates to be of an impressively high level. On top of that, it has a flicker reduction setting and a blue light mode, reducing the strain of those long, nighttime gaming sessions. 

The AOC Agon AG352UCG6 Black Edition produces excellent colors on a widescreen setup. It's also simple in its design: a two-part aluminum base supports its lovely curved screen. There are certainly better-looking monitors out there if that's a point of contention for you.

1. Alienware AW2521HF

Best 240Hz Freesync gaming monitor

Screen size: 25-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 1920 x 1080 | Response time: 1ms | Refresh rate: 240 Hz | Weight: 20 lbs

Great Contrast
Fast 240Hz panel
Both G-Sync & FreeSync compatible 
Expensive

There are fast gaming monitors and then there are fast gaming monitors. This Alienware 25 gaming monitor falls under the latter. The AW2521HF is one of the better FreeSync monitors you can buy right now if your life is all about competitive shooters. 

This 1080p display is geared toward esports with a 240Hz refresh rate and a 1ms response time. Another thing we like about Alienware's offering is that it uses an IPS panel over TN which means you'll get viewing angles and, more importantly, great color.

2. BenQ EL2870U

Best budget FreeSync 4K monitor

Screen size: 28-inch | Panel type: TN | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 1ms | Refresh rate: 60 Hz | Weight: 15.9 lbs

Affordable 4K HDR
Built-in stereo speakers
Solid response time
Compromised viewing angles
Low refresh rate

The BenQ EL2870U is a killer budget 4K monitor. It's a high quality, robust model for starters, but it also boasts 4K and HDR support. Plus, it's very affordable. 

It is only a TN panel, which means you're dealing with limited viewing angles, but it makes up for this in other areas. Its response time competes with the best of them, at 1ms. The HDR can be toggled on/off with a touch of a button too.

Since it regularly goes on sale for less than its already-reasonable list price. If your search is limited to FreeSync monitors, then this would be our top 4K pick, and a challenge for our top overall pick.
