But what does G-Sync do anyway? Essentially G-Sync is Nvidia's frame synchronisation technology, which uses dedicated monitor processing to attune your monitor's refresh rate to your graphics card's output, for a smooth gaming experience. You'll need an Nvidia graphics card to make the most of this tech, though, and these cards are pretty elusive right now. 

You've probably seen gaming monitors proudly display they're G-Sync Ready or G-Sync Compatible. These kinds of monitors include no dedicated silicon, so they'll often be a cheaper option. For best results on an Nvidia-bound setup, find one that's been certified by Nvidia. The added benefit here is that they also offer support for AMD's competing FreeSync technology. 

But be aware, while G-Sync features work with 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.

This isn't just the best G-Sync gaming monitor, it's 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.

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 front too. 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.

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.

Acer Predator XB273KOne of the highest quality and best bang for buck G-Sync monitorsSpecificationsScreen size: 27-inchPanel type: IPSAspect ratio: 16:9Resolution: 3840 x 2160Response time: 4 msRefresh rate: 120 Hz (overclocked to 144 Hz)Connectivity: 5 x USB 3.0Weight: 15.9 lbsTODAY'S BEST DEALSPrime$629.99View at Amazon$699.99View at Walmart$849.99View at NeweggSee all prices (4 found)14 Amazon customer reviews☆☆☆☆☆Reasons to buy+Excellent picture quality+Great for gaming+Good menu optionsReasons to avoid-Minimum-spec HDR

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 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.

Acer Predator XB321HKBest G-Sync monitor for high-end graphics setupsSpecificationsScreen size: 32-inchPanel type: IPSAspect ratio: 16:9Resolution: 3840 x 2160Response time: 4 msRefresh rate: 60 HzWeight: 24.9 lbsTODAY'S BEST DEALSPrimeLow Stock$2,062.37View at Amazon440 Amazon customer reviews☆☆☆☆☆Reasons to buy+Great size for a 4K resolution+Brilliant colors and contrastsReasons to avoid-Low refresh rate

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.

AOC Agon AG352UCG6 Black EditionBest superwide curved G-Sync monitorSpecificationsScreen size: 35-inchPanel type: VAAspect ratio: 21:9Resolution: 3440 x 1440Response time: 4 msRefresh rate: 120 HzWeight: 26 lbsTODAY'S BEST DEALSCheck Amazon996 Amazon customer reviews☆☆☆☆☆Reasons to buy+Brilliant colours and contrasts+Competitively pricedReasons to avoid-Not the punchiest picture quality

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.

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.

BenQ EL2870UBest budget FreeSync 4K monitorSpecificationsScreen size: 28-inchPanel type: TNAspect ratio: 16:9Resolution: 3840 x 2160Response time: 1msRefresh rate: 60 HzWeight: 15.9 lbsTODAY'S BEST DEALSPrime$299.99View at Amazon$299.99View at Walmart$299.99View at NeweggSee all prices (8 found)Reasons to buy+Affordable 4K HDR+Built-in stereo speakers+Solid response timeReasons to avoid-Only 60Hz refresh

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.
