The best G-Sync monitor will deliver the most buttery-smooth gaming experience your Nvidia graphics card can provide. Ever since Nvidia G-Sync tech started becoming a household monitor feature in 2013, it's still is the best option to prevent screen tearing and display stuttering when gaming. 

So, what is G-Sync, and what does it do? G-Sync is Nvidia's frame synchronization 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 need an Nvidia GPU to make this happen, and those are pretty hard to find 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. 

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, we picked out some of our favorite FreeSync monitors at the bottom of the page.

1. Asus ROG Swift PG279Q

Best G-Sync monitor for gaming at 1440p

Specifications
Screen size: 27-inch
Panel type: IPS
Aspect ratio: 16:9
Resolution: 2560 x 1440
Response time: 4 ms
Refresh rate: 144 Hz (overclocks to 165 Hz)
Weight: 15.4 lbs
Reasons to buy
+1440p with 144Hz refresh rate, overclockable to 165Hz+Extremely fast refresh, low input lag for an IPS screen
Reasons to avoid
-Requires calibration for best picture.

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 and 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

Specifications
Screen size: 34-inch
Panel type: IPS
Aspect ratio: 21:9
Resolution: 3440 x 1440
Response time: 4 ms
Refresh rate: 120 Hz
Weight: 16 lbs
Reasons to buy
+Brilliantly fast for a superwide monitor+Sleek design for a large monitor
Reasons to avoid
-No HDR-Contrast ratio & black uniformity aren't the best

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 tends to give your games an epic feel, particularly third-person titles. 

Away from the cold hard specs, this is one of the monitors that also wins on the design front. 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. Acer Predator XB273K

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

Specifications
Screen size: 27-inch
Panel type: IPS
Aspect ratio: 16:9
Resolution: 3840 x 2160
Response time: 4 ms
Refresh rate: 120 Hz (overclocked to 144 Hz)
Connectivity: 5 x USB 3.0
Weight: 15.9 lbs
Reasons to buy
+Excellent picture quality+Great for gaming+Good menu options
Reasons to avoid
-Minimum-spec HDR

Never mind 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 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.

4. Acer Predator XB321HK

Best G-Sync monitor for high-end graphics setups

Specifications
Screen size: 32-inch
Panel type: IPS
Aspect ratio: 16:9
Resolution: 3840 x 2160
Response time: 4 ms
Refresh rate: 60 Hz
Weight: 24.9 lbs
Reasons to buy
+Great size for a 4K resolution+Brilliant colors and contrasts
Reasons 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.

1. Alienware AW2521HF

Best 240Hz Freesync gaming monitor

Specifications
Screen size: 25-inch
Panel type: IPS
Aspect ratio: 16:9
Resolution: 1920 x 1080
Response time: 1 ms
Refresh rate: 240 Hz
Weight: 20 lbs
Reasons to buy
+Great Contrast+Fast 240Hz panel+Both G-Sync & FreeSync compatible 
Reasons to avoid
-NO HDR

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

Specifications
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
Reasons to buy
+Affordable 4K HDR+Built-in stereo speakers+Solid response time
Reasons 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.
