Looking at one of the best G-Sync compatible FreeSync monitors can be an incredibly shrewd move. Taking this approach will throw you into a particular world of great monitors but also save you some money by avoiding the G-Sync 'proper' premium while still getting you, effectively, a G-Sync monitor. Smooth. And you don't have to rely just on us for the information that some FreeSync monitors work with G-Sync - Nvidia themselves tested loads of monitors in order to find out which models work best with its G-Sync adaptive sync technology.

But what's the actual deal with these, the best G-Sync compatible FreeSync monitors? Well, it means you can pick up one of the best graphics cards⁠ from either the Nvidia or AMD family and benefit from super smooth pictures, frame rates, and low input lag. Adding one of the best G-Sync compatible FreeSync monitors to your setup allows you to add in the benefits from enabling Nvidia's G-Sync tech too, which is an enormous bonus.

While most of the best gaming monitors are native G-Sync models - and the best 4K monitors for gaming are hard to get the fast refresh rates for - this development and sharing of tech means you don't always have to pay a premium to get the picture-smoothing tech. You can get a full list of G-Sync monitors here at Nvidia's website, but a great place to start your search is right here with our top picks for the best G-Sync compatible FreeSync monitors money can buy right now.

ASUS VG27AQ

The best G-Sync compatible FreeSync monitor

Screen size: 27-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 2560 x 1440 | Response time: 1ms | Refresh rate: 144Hz (Overclockable to 165Hz) | Weight: 15.9 pounds

Terrific quality to pictures
Great colours and vibrancy
Lovely and smooth
Good settings menu
Some in-game edges have a bit of a blur
Matte finish gives lighter pictures a sheen 

The VG27AQ is a really great monitor, that would be at home in other best lists, not just in this niche. It's a great IPS panel that has quality speeds and would be a fine choice for a PC player or console owners - or better, both. It was a joy to play both types of systems on that it'd really suit a multi-monitor and multi-device/system setup.

in my ASUS VG27AQ review I was impressed by basically all it offered; it is exceptionally versatile and turned its hand to anything. The slight downsides of a little haze and sheen here and there are just that - slight. The rest of what the VG27AQ offers easily makes this the best G-Sync compatible FreeSync monitor going right now.

ASUS XG27UQ monitor

The best bang-for-buck 4K G-Sync compatible FreeSync monitor

Size: 27-inch | Resolution: 4K (3840x2160) | Refresh Rate: 144Hz | Response Time: 1ms | Panel: IPS | Ports: 2x HDMI 2.0, 2x DisplayPort, 2x USB 3.0, earphone jack

Perfect specs of 4K, 144Hz, 1ms
It's far cheaper than any other monitor with similar specs
The best way to play the latest AAA games
Quite expensive
Need a 3080 or better to unlock its full potential

Until now, 4K60fps+ gaming has been a concept only attainable by the hardcore enthusiasts who dedicate everything they have to PC gaming. Not anymore. Thanks to the recent launch of the 30-series cards from Nvidia, and AMD's RX series equivalents, it's finally affordable for those who desire it. To reach that level, you need one of the best monitors on the market, but they're usually more expensive than the graphics cards themselves.

The ASUS XG27UQ changes that entirely, bringing almost the best possible specs on a 4K screen down to a reachable tier for general PC gamers. It's still not cheap, but for the first time ever a 4K monitor with 1ms response time and a 144Hz refresh rate is below the $1k mark. Quite considerably actually, coming in at around $800/£800. It's still a hefty price tag, don't get me wrong, but it's far cheaper than the other top tier offerings.

The ASUS XG27UQ is like a gaze into what PC gaming will be like for everyone 5 to 10 years down the line. With ray tracing on, Cyberpunk 2077 had my jaw on the floor, with stunning lighting effects and texture detail throughout Night City. As did Assassin's Creed Valhalla, with the sunrays splitting the treetops. if you have a rig capable of it – seriously, don't upgrade to 4K if your graphics card is a few years old – then you will not be disappointed with this monitor.

Dell S2721DGF review

Dell S2721DGF monitor

A high-performing gaming monitor that doesn't go overboard on RGB

Size: 27-inch | Resolution: 1440p | Refresh Rate: 165Hz | Response Time: 1ms | Panel: IPS | Ports: 2x HDMI, 1x DisplayPort, 5x USB 3.0, headphones, audio line-out

All the best specs; 1440p, 165Hz, 1ms
Wide viewing angles
Stunning, sleek design
Poor HDR performance and dark areas

Dell offers a lot of monitors, from basic 1080p run-of-the-mill office jobs to uber impressive 4K beauties. The S2721DGF slots firmly in the middle, offering gaming performance at 1440p, and while the specs are those you'd expect of a top-notch competitive esports ready screen, it certainly doesn't look like one on the outside.

When any PC gamer is looking for a monitor, two specs are vital; refresh rate and response time, and - often, G-Sync compatibility. The Dell S2721DGF is almost perfect in this regard, offering 165Hz and 1ms respectively, as well as that sweet Sync tech. Another attraction is the IPS panel, which is excellent and contributes to the bang-to-buck value that the monitor offers. The monitor is covered in a matte, all-black finish, with thin, flat bezels around the edge, making it a brilliant choice for anyone looking for a double or triple-monitor set-up.

The only place this monitor trips up is in HDR performance, especially dark areas. The contrast is low, which means it's often hard to differentiate between subtle blacks and greys, but if you're using this primarily for gaming and not movie-watching, it's not too big of a deal. This is one of the best 1440p G-sync compatible FreeSync monitors on the market.

Razer Raptor 27

A quality option from a quality peripheral maker

Screen size: 27-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 2560x1440 | Response time: 1ms | Refresh rate: 144Hz | Weight: 12.3 lbs

Superb image quality and crispness
Some of the best colors and contrasts
Excellent speeds to back up the G-Sync compatibility
Great Razer design
A bit pricey

Razer's first foray into gaming displays is a great success. The Raptor is a 27-inch panel that has quality specs under the hood. An IPS panel with a 1440p resolution, it has a 1ms response time and 144Hz refresh rate; and it offers that sweet G-Sync compatibility.

Elsewhere, there's also a slick black design that has RGB in the stand - because of course it does - and a mesh material all over the back, much like you'd find on speakers. The traditional Razer-green cables contrast nicely with the black stand and monitor and are tidily kept in check at the back with cable guides, too. The ports will have you covered practically speaking too: an HDMI, a DisplayPort, one USB-C, two USB 3s, and a headphone jack.

This is a terrific gaming monitor all in then, and one which has a quality of picture that alone makes it easy to recommend as one of the best G-Sync compatible FreeSync monitors. The screen's speed is fast and pacey for smooth pictures, the image quality is crisp and gorgeous, and the color range and contrasts are deep and immersive. It's a little pricey perhaps, but if you're looking for a great PC monitor that has compatibility with Nvidia's screen tech, this sure is a strong contender.

AOC Agon AG273QX

A speedy demon with image quality to boot

Screen size: 27-inch | Panel type: VA | Aspect ratio: 16:9 | Resolution: 2560 x 1440 | Response time: 1ms | Refresh rate: 165Hz | Weight: 17.2 pounds

Blistering screen speeds
Wonderfully bright and vivid pictures
Decent pre-sets
Good picture quality
Good value
Massive, intrusive stand
Contrasts are just OK in darker games

If speed is paramount for you in your G-Sync compatible FreeSync monitor, then this AOC model is very worthy of your consideration. We think that 1440p gaming is still the sweet spot for gaming setups right now so this 27-inch, QHD, FreeSync 2, VA panel with blistering speeds - 165Hz refresh; 1ms response - is right up there when it comes to speed-focused gaming at that perfect resolution. It doesn't compromise too much on image quality too and had real quality colour and HDR chops to make this monitor offer much more than just the speedy element. A decent all-rounder for those looking to have a speedy-focus to their monitor but one of the best ones going if you're just chasing those speeds.

Read more in our full AOC Agon AG273QX review here. And please note that this model is unfortunately not available in the US yet. It might well come to that side of the pond, but for the moment this is an EU-only model. In the US, your closest available AOC match would probably be the AOC C27G2

AOC G2590FX

A tremendous budget G-Sync compatible FreeSync option

Screen size: 24.5-inch | Panel type: TN | Aspect ratio: 16:9 | Resolution: 1920 x 1080 | Response time: 1ms | Refresh rate: 144Hz | Weight: 9.26 lbs

Excellent color range
Super slim bezel
Sub-par viewing angles

Despite being 'just' a TN panel the AOC G2590FX is a super affordable entry point into high frame rate gaming on an almost bezel-less screen.  The loss of viewing angle and really rich colors that a TN panel can give you is compensated by a lightning refresh rate of 144Hz and a zippy 1ms response time. This 25-inch monitor can show off frames fast as your GPU can squeeze them out, no jaggies or input lag permitted, especially as it's got that sweet G-Sync compatibility.

Alienware AW2720HF

A premium option from a premium manufacturer

Screen size: 27-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 1920 x 1080 | Response time: 1ms | Refresh rate: 240Hz | Weight: 28.24 lbs

Great design
Very fast refresh rateGreat all-round specs
'Only' 1080p

This is a great monitor if your budget is in the $400 / £400 range. Alienware's 27-inch model is a thing of beauty on the outside, with a stylish design that we've come to know from Dell's gaming wing, and a gaming beast on the inside. A 1080p IPS panel that offers a lightning-quick 1ms response time and an astonishing 240Hz refresh rate all combine to make a great gaming monitor that would be a great fit for any player. I suppose if we're being picky, it would be even better to have all those specs at a 1440p resolution but that would certainly bump the cost up by a fair chunk. A fine monitor from a good manufacturer that oozes quality and style.

Samsung C27RG5

Best curved G-Sync compatible monitor

Screen size: 27-inch | Panel type: VA | Aspect ratio: 16:9 | Resolution: 1920 x 1080 (at 1500R) | Response time: 4ms | Refresh rate: 240Hz | Weight: 10.14 lbs

Glorious curved panel
Quality gaming speeds
Only a VA panel

This is probably the best curved specimen you can get in the G-Sync compatible FreeSync monitor niche. It's a great looking thing, and if you're in the market for any form of quality curved screen (or two!) then this is a fine contender from a trusted screen maker. Where speeds can sometimes be affected by a curved panel, the C27RG5 offer a blistering 240Hz refresh rate along with a 4ms response time. Apply those to a 27-inch, 1080p 1500R monitor and you'll have some of the fastest and smoothest images available on a gaming monitor, and some of the crispest, utilising Samsung's excellent in displays. 

Extending their expertise in TVs to gaming monitors, Samsung have created a glorious gaming monitor that will enhance your immersion in games very nicely indeed. Curved monitors seem to draw you in very pleasingly, just by their design and the C27RG5 is no different.

Acer Nitro XV273K

The best 4K pick

Screen size: 27-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 1ms | Refresh rate: 144Hz | Weight: 14.5 lbs

4K resolution!
Premium compilation of specs
A bit pricey

As you can imagine a lovely 4K resolution on a monitor oozing quality gaming specs does bump up the price a bit. However, the Acer Nitro XV273K and its specs do go a long way to justify the price tag, and it's a worthwhile investment if you want the biggest resolution in this niche of gaming monitor. Its a tremendous 4K HDR IPS-panel monitor that's G-Sync compatible - an excellent start. This is then reinforced by the particulars of the aforementioned gaming specs in the form of a a 144Hz refresh rate and a 1ms response time. Neither of which are easy on a 4K panel. All that, and it is from a reputable maker of quality gaming monitors, a great option.

Alienware AW2521HF

A G-Sync compatible monitor fit for those competing at the very top

Screen size: 24.5" | Aspect ratio: 16:9 | Resolution: 1920 x 1080 @ 240Hz | Response time: 1ms | Brightness: 400 cd/m2 | Contrast ratio: 1,000:1 | Viewing angle: 178° H&V | Features: IPS panel, Nvidia G-Sync & AMD FreeSync support, LED backlight & edgelight, USB 3.0 hub, preset game modes including built-in FPS counter

Rapid response time and high refresh rate
Sleek, matte black design
Four USB 3.0 ports with simple cable management
Uneven blacks and unimpressive picture quality
Suited only for competitive gaming

The Alienware AW2521HF is one of the most affordable 1080p 240Hz G-Sync compatible FreeSync monitors with a 1ms response time out there, making it an ideal choice for gamers who want to compete at the highest level in games like Valorant, Counter-Strike: Global Offensive, League of Legends, or anything else with an elite esports scene. On that front, it excels, with buttery smooth motions and its G-Sync compatibility is key in that regard.

Unfortunately though, if you're a fan of playing non-competitive or single-player games and appreciate the ever-improving graphics in the latest games, you may prefer to opt for a 1440p or 4k monitor with a 144Hz refresh rate so your games look even better. If those are out of your price range, even a 144Hz 1080p monitor may be the preferred choice because this display has a problem with uneven blacks, making dark scenes look slightly dodgy. This is also the case if you're watching movies or TV shows on it. A brilliant monitor with a very specific audience.

ASUS MG278Q

An excellent 1440p option

Screen size: 27-inch | Panel type: TN | Aspect ratio: 16:9 | Resolution: 2560 x 1440 | Response time: 1ms | Refresh rate: 144Hz | Weight: 16.87 lbs

Sweet spot of 1440p resolution
Very fast speeds

If you are enjoying the 1440p realm then you can't go wrong with the ASUS MG278Q as your go-to G-Sync compatible FreeSync monitor. From an extremely trusted and proven manufacturer, this panel has a pacey response rate and refresh rate, and won't totally break the bank. It's certainly one of a bunch of other monitors in that it['s not got a headline spec or attraction, in a way, but it's still a superb 1440p G-Sync compatible monitor.

AOC C27G2U

An aggressively priced monitor - but not without its flaws

Screen size: 27-inch; 1500R curve | Panel type: VA | Aspect ratio: 16:9 | Resolution: 1920 x 1080 | Response time: 1ms | Refresh rate: 165Hz | Weight: 16.87 lbs

Speedy refresh rate
Quality design and build
Great price point
Disappointing levels of brightness
Poor pixel response

Want high refresh? It’s going to cost you. But not quite as much as before. AOC’s new 27-inch monitor packs a curved VA panel, 1ms response, and 165Hz, all for around £240 / $260. You also get both G-Sync and FreeSync adaptive refresh support, plus a four-port USB 3.0 hub, HDMI and DisplayPort connectivity for both PC and console compatibility, and a good looking, multi-adjustable chassis and stand. That’s quite an overall package for the price.

What you don’t get, sadly, is terribly punchy performance. Rated at just 250 nits, this is not a terribly vibrant monitor, even if black levels from the VA panel are excellent. Arguably even more of an issue is the mediocre pixel response, which does entirely square with the 1ms rating.

By other metrics this is a nice screen and a great G-Sync compatible FreeSync monitor. The 165Hz refresh translates into a really fluid framerate and minimal input lag, while the relatively 1080p native resolution means you don’t need a thousand-dollar graphics card to achieve those high frame rates. It’s just a pity the AOC C27G2U stumbles so obviously at its core competence as a gaming panel. It really should be both brighter and faster. As it is, it’s aggressively priced enough to still merit consideration, just be aware that it comes with some fairly obvious limitations.
