Looking at the best G-Sync monitors can be an excellent method to help narrow down your options when researching your monitor options. By incorporating a monitor's G-Sync capability you can really quickly and effectively mark your best choices as the marrying of internal components and your external peripherals that they offer is an excellent combination to achiever. This decision then gets the most out of your Nvidia card - and what better time to do so with the brand new 30-series adorning best graphics card lists across the internet this autumn. 

And even though AMD's graphics cards are enjoying great success as alternatives to the traditional go-to's that are Nvidia's GPUs, it is the latter that a lot of PC gamers will still lean toward, with one reason being the benefits of G-Sync. But what is G-Sync? Well, G-Sync is a monitor or screen tech that synchronizes the pictures refresh rates to the frames your rig is pumping games out at. This means a reduction in screen tearing and stuttering of pictures which can be frustrating to the point of making games unplayable (in its worst state). An Nvidia graphics card and one of the best G-Sync monitors working together basically smooths this out completely making all your games - even the fast ones - buttery and silky smooth. Simply put, G-Sync takes great monitors and turns them into some of the best gaming monitors going.

Teaming your graphics card specifically with one of the best G-Sync monitors may at first feel like a bit of an unwanted demand that one of your components is making, but it is literally the best way to team your most important peripheral for taking you into games, and probably your most important component - and it will bag you that unique-to-Nvidia-GPU feature.

The thing is, the best monitors with G-Sync will demand a slightly higher price tag than their FreeSync counterparts. This is just par for the course for getting a more premium screen tech in your monitor - it adds a bit to the cost, so you'll need to be patient, save, and ready to pounce on discounts as they come up too. But to help you find the right model and the right deal for you, we've rounded up our picks for the best G-Sync monitor you can currently get, casting a wide net for a lot of players' needs, featuring some of the best 4K monitors for gaming, down to cheerful, excellent 1080p options.

ASUS ROG Swift PG279Q

The best G-Sync monitor

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

G-Sync married with great speeds
1440p with 144Hz refresh rate
Extremely fast for an IPS panel
'Only' a 4ms response time

This is the premier G-Sync monitor. It doesn't turn everything up to 11 in terms of being ridiculously bombastic, but what it does do is offer serious excellence in all that it offers with awesome gaming specs and a decent price tag to boot. A key to it being so good is its resolution as a starting point: a 1440p screen offers much more than 1080p does yet doesn't go all out ridiculous and demanding as a 4K resolution would.

It's one of the best G-Sync monitors that really hits the sweet spot for gaming: 1440p resolution and quick as hell refresh and response times on an IPS panel at the perfect size of 27-inches. Basically the perfect mix. Away from purely G-Sync monitors, this is actually one of the best anybody can buy for any kind of setup such is its quality. That's why the above 'negative' point is being really picky. Elsewhere, it's got a cool design we've come to know and love from ASUS and plenty of ports to keep you satisfied - though you'll have to use the DisplayPort to maximize and get that overclocked refresh rate.

Acer Predator XB241H

Best budget G-Sync monitor

Screen size: 24-inch | Panel type: TN | Aspect ratio: 16:9 | Resolution: 1920 x 1080 | Response time: 1ms | Refresh rate: 144Hz | Weight: 13.9 lbs

Excellent price point
Cool, Acer design
Great performance for a 1080p monitor
Limited ports

This is a great G-Sync monitor, and one that doesn't add quite as much of a premium to its price for the luxury of offering the tech. The Acer XB241H tones everything down ever so slightly in terms of resolution, screen size and panel type but the subsequent changes are combined to make one of the best G-sync monitors that won't destroy your bank balance.

The XB241H is a 24-inch monitor that has a 1080p resolution on a TN panel. It offers the oft-seen 144Hz refresh rate as standard but, as it's a TN panel, can offer much faster response times - it comes in at just 1ms. Lightning. Its port setup could be seen to be a bit stingy though: it only has one HDMI and one DisplayPort. However, the price point of the monitor combined with the G-Sync, as well as all the above genuinely good gaming specs and pedigree that Acer offers means you will not be disappointed by this wonderful, smaller monitor. If you had to get two 24-inchers for a multi-monitor setup then I couldn't think of any better model to go for.

Acer Predator XB273K

Best 4K HDR G-Sync monitor

Screen size: 27-inch | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 4ms | Refresh rate: 144Hz | Weight: 15.9 pounds

Great value for a highly-specced monitor
Brilliantly detailed pictures
Offers really fast speeds for a 4K IPS
Not the highest quality version of HDR

This is a beastly monitor in almost every respect. This is the most expensive and chock-full of quality specs model on this list and offers pretty much the best G-Sync monitor going right now if you have a big budget (but not crazy big) - thus there is still some value to this monitor's price tag and what it gets you.

The headline spec for the Acer XB273K is that it is a 4K gaming monitor - a whopping resolution of 3840 x 2160. The second headliner is that it's a 4K monitor that also offers HDR. High dynamic range really takes colors and contrasts to another level, and until relatively recently was limited to our TVs only. Now it's a welcome addition to gaming monitors. On top of that, the XB273K offers that sweet G-Sync and applies it to an IPS panels capable of 144Hz refresh and 4ms response. For a 4K monitor, this is exquisite. You'll need a beastly PC to really push the monitor to use all its bells and whistles to its maximum but anything remotely close will be a true treat too.

If we're really strict, the HDR is fine, but not mind-blowing. However, if you really wanted to chase the HDR dream, you'd be looking at adding hundreds more to the price so that's why this is your best bet to get a 4K HDR G-Sync monitor in terms of value and what you get for your money.

(Small note: this monitor has two different variants which are very similarly named so note which one it is you're interrogating through the links below. One is G-Sync 'proper' and one is G-Sync compatible - they are both very good!)

AOC AGON AG352UCG6

Best curved G-Sync monitor

Screen size: 35-inch | Panel type: VA | Aspect ratio: 21:9 | Resolution: 3440 x 1440 | Response time: 4ms | Refresh rate: 120Hz | Weight: 26.01 lbs

Good price pointpriced
Great colours and contrasts
Lovely, immersion-increasing panel
Hogs desk space

If you prefer your gaming monitors curved and immersion-increasing then this beauty of an AOC model - or its Black Edition sibling - is for you. Banging the drum of the 1440p sweet spot once more, here we have a monitor that stretches it out ever so slightly to that super-wide, 21:9 ratio, 3440x1440 resolution. And boy does it do it well; the AOC Agon AG352UCG6 really enjoys the elegance and picture quality of the middle ground between HD and 4K.

If you're looking to get a single monitor that can offer a great viewing, playing, watching, and user-experience in one package then this 35-inch monitor could be ideal. That 35-inches is stretched across a sweet VA panel that offers a decent 120Hz refresh rate - good for a curved screen - and a good 4ms response time to ensure smoothness of your inputs and the pictures on screen. Mix G-Sync into the mix here too and the specs really start to sell the monitor.

However, the design is also super; it has three legs elegantly stretching out to support the large body of the monitor with an aesthetic of black, silver, and red livening up your setup. Curved monitors always seem to pull you in a bit more and the effect is no better than with the AG352UCG6 as a pick for the best G-Sync monitor with that extra layer of immersion.

Alienware AW3418DW

A great 21:9 flat G-Sync monitor

Screen size: 34-inch | Panel type: IPS | Aspect ratio: 21:9 | Resolution: 3440 x 1440 | Response time: 4ms | Refresh rate: 120Hz | Weight: 16.02 lbs

Brilliantly fast for a superwide monitor
Sleek design for a big screen
Comes with an Alienware premium

The second of the curved options on the list, this Alienware monitor is an equally great 21:9 option as the AOC above. It feels slightly more compact tho with its 34-inch monitor and its sleek design - the aesthetic is true to Alienware's heritage and reputation of awesome-looking gaming hardware and is a great looking thing in and of itself, let alone when displaying in-game pictures beautifully.

The G-Sync on this great monitor combines wonderfully with the 120Hz refresh rate and 4ms response time to offer some solid gaming speed specs that you can have confidence in. The ports are pretty standard - one HDMI and one DisplayPort - but the 1900R curve is really a thing of beauty and allows for great viewing angles.

The user-experience, cold, hard specs, and design that this monitor offers, as well as its slick design may win over some who want to splash out a bit on a curved, G-Sync monitor. If you are OK with stomaching the slight Alienware premium that the monitor demands, too. If you're a fan of keeping your equipment on brand, then this would be one of the best G-sync monitors to pair up with an Alienware PC or laptop.

ASUS ROG Swift PG27UQ

When money's no option, the top G-Sync monitor

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

Quality speeds for a 4K monitor
Cool design
Great image quality
G-Sync technology
You need to take out a second mortgage to afford it
Needs a monstrous PC to get the most out of it

The price tag of this monitor will raise eyebrows quickly but when you cram so much quality tech into one monitor, the price is expected to be lofty. But that's also because its a premium worth paying for and will likely last many, many years to come.  It's a quality monitor in its own right before you get to the fact that its G-Sync and 4K. And you can boost the refresh rate to 144Hz and above, plus it's a great desk-size of 27-inches, has HDR and is well suited to a multi-device setup. It really is the whole package and, as a result, one of the best G-Sync monitors going if you have a large budget to play with.

However, along with the price tag which will be too high for most, the other downside is more 'invisible' at first: you'll need a beast of a machine to enjoy PC gaming beyond 60Hz at the 4K resolution. That's why this is a great multi-device G-Sync monitor, though consoles won't make use of the G-Sync good-ness. Nonetheless, if you're after the most premium G-Sync monitor then this is it, and if you have a machine to make use of everything it can offer, then kudos to you.
