The Best G-SYNC Monitors (2021 Reviews)

Looking for the best G-SYNC monitors to pair with your powerful NVIDIA gaming graphics card? Look no further, our guide has everything you need.

Even though you can now use FreeSync with NVIDIA cards, there are still upsides to utilizing your GeForce graphics card with a gaming display that has a dedicated G-SYNC module.

In comparison to FreeSync or G-SYNC Compatible monitors, G-SYNC displays have a special chip installed, which in addition to providing a wider variable refresh rate range, offers lower input lag and variable overdrive.

However, sometimes a G-SYNC Compatible monitor will be just as good as its G-SYNC counterpart, but at a much lower price.

Therefore, we’ve put together this buyer’s guide consisting only of the G-SYNC gaming monitors that are actually worth considering.

About The Monitor

Want the best G-SYNC monitor for competitive gaming there is? The Dell Alienware AW2521H is for you!

Image Quality

Based on a 24.5″ 1080p IPS panel with an sRGB color gamut, a 400-nit peak brightness and a 1,000:1 contrast ratio, the Dell AW2521H offers the same viewing experience as the more affordable 144Hz and 240Hz models with these specifications.

So, you get accurate and consistent colors, wide viewing angles, a decent pixel density, and more than enough brightness even for well-lit rooms.

However, thanks to its rapid 360Hz refresh rate, it delivers the most responsive gaming experience possible, which is why competitive games will absolutely love it.

To a casual gamer though, the difference between 360Hz and 240Hz most likely won’t be worth $700, which is how much this display goes for.

One of the reasons for such a high price is the G-SYNC module, but it ensures buttery-smooth variable refresh rate and overdrive performance with no ghosting or overshoot across the entire refresh rate range. 


Moving on, the Dell AW2521H offers plenty of extra gaming features, such as on-screen timers, various pre-calibrated picture modes and Dark Stabilizer for better visibility in darker games.

It also supports the NVIDIA ULMB (Ultra Low Motion Blur) backlight strobing technology, which works at 144Hz and 240Hz.

This technology further reduces motion blur, but it sacrifices picture brightness in the process, and it cannot be active at the same time as G-SYNC.

Design & Connectivity

Dell Alienware AW2521H Monitor Design

The stand of the Dell AW2521H monitor offers full ergonomic support with up to 130mm height adjustment, +/- 20° swivel, -5°/21° tilt, 90° pivot and VESA mount compatibility.

Connectivity options include two HDMI 2.0 ports (limited to 240Hz), DisplayPort 1.4, a headphone jack, and a quad-USB 3.0 hub.


The Acer Nitro XV252QF is a 1080p 360Hz IPS gaming monitor with no dedicated G-SYNC module going for ~$500. It’s not certified as G-SYNC Compatible but offers stable VRR performance with both AMD and NVIDIA GPUs.

Moreover, its MBR implementation allows for backlight strobing all the way up to 360Hz – and even 390Hz when overclocked.

Since most competitive gamers don’t use variable refresh rate but rather play with uncapped FPS or with backlight strobing, we recommend checking out our Acer XV252QF review to find out which monitor is best for you.

The Pros:

  • 240Hz refresh rate
  • Quick response time, low input lag
  • Fully ergonomic stand and rich connectivity options
  • Wide Adobe RGB color gamut and viewing angles

The Cons:

  • No DSC and MBR technology

About The Monitor

If you want a larger screen with a higher resolution, check out the ASUS ROG Swift PG279QM.

Image Quality

Thanks to its QHD resolution of 2560×1440 pixels, you get the ideal pixel-per-inch ratio of 108 PPI on the 27″ viewable screen of the ASUS PG279QM.

As a result, you get plenty of screen real estate as well as crystal-clear details and text, without any scaling necessary.

Additionally, the monitor has a wide 99% Adobe RGB color gamut, which makes for vibrant and saturated colors (~150% sRGB).

There’s also an sRGB emulation mode that can restrict the monitor’s native gamut to ~100% sRGB for more accurate color output.

On top of that, the monitor’s peak brightness goes up to 550-nits for HDR content and there are 16 dimming zones that can dim parts of the image that need to be dark, without greatly affecting the bright areas.


Other noteworthy gaming features include various picture presets, AuraSync RGB lighting, Dark Boost, on-screen timers and a refresh rate tracker.

Design & Connectivity

ASUS PG279QM Monitor Back

The stand boasts premium build quality and versatile ergonomics with up to 100mm height adjustment, +/- 25° swivel, 90° pivot, -5°/20° tilt, and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.4, three HDMI 2.0 ports (limited to 144Hz), a headphone jack, two 2W built-in speakers and a dual-USB 3.0 hub.

Keep in mind that DisplayPort 1.4 is limited to 8-bit color at 240Hz. For 10-bit color, you’ll need to lower the refresh rate to 144Hz.

Luckily, the difference between 8-bit and 10-bit color is not really that noticeable in video games.

The Pros:

  • 144Hz refresh rate
  • Good response time, low input lag
  • Fully ergonomic stand and rich connectivity options
  • DisplayHDR 1400

The Cons:

  • Expensive
  • Noticeable blooming in some scenes
  • Not as fast as some IPS panels

About The Monitor

In case you can afford something pricier, the ASUS ROG Swift PG32UQX offers an amazing HDR viewing experience as well as responsive gameplay.

Image Quality

The 4K resolution results in even sharper details on 32″ sized screens, but you will have to use scaling in order to make small items such as text readable.

What makes this gaming monitor so special though, is the 1152-zone mini LED full-array local dimming (FALD) solution.

Unlike the 16 edge-lit zones on the ASUS PG279QM, the ASUS PG32UQX has 1152 zones across the entire screen allowing for better dimming control.

On top of that, the monitor has a stellar 1600-nit peak brightness and covers 99% of Adobe RGB color space.

These things combined provide you with the true ‘HDR’ viewing experience with deep blacks, bright highlights, and vibrant colors.

Now, as there are 1152 dimming zones and over 8 million pixels, in certain scenes, some light may bleed into the surrounding zones creating a halo/bloom effect.

It’s usually not visible in games or movies, and it’s mostly negligible when it is.

It can mainly be annoying in regular desktop use (for instance, when moving a white cursor across a dark background), but you can simply disable local dimming when not playing games or watching videos.

Besides the lower refresh rate than that of the ASUS PG279QM, the ASUS PG32UQX also doesn’t have quite as fast pixel response time speed, so some minor ghosting might be detectable in some scenes, but it’s tolerable.


In the OSD (On-Screen Display) menu of the monitor, you’ll find plenty of useful features, including pre-calibrated picture prests, on-screen timers and crosshair overlays, and RGB lighting adjustments.

Visit our ASUS PG32UQX review for more information.

Design & Connectivity

ASUS ROG Swift PG32UQX Monitor Design

Due to the full-array local dimming solution, the bezels are a bit chunky, but the stand is well-built and fairly ergonomic with up to 70mm height adjustment, -5°/20° tilt, +/- 20° swivel and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.4 with DSC, three HDMI 2.0 ports, a headphone jack and a dual-USB 3.0 hub. There’s an extra USB 2.0 port at the top of the screen as well as a mounting socket for a webcam.

The HDMI 2.0 port on this monitor also supports 4K 120Hz with 4:2:0 color format for the Xbox Series X.


  • ASUS PG27UQX – The upcoming 27″ sized version of this monitor with a mini LED backlight and 576-zone local dimming.

The Pros:

  • 144Hz refresh rate
  • Good response time, low input lag
  • Fully ergonomic stand and rich connectivity options
  • DisplayHDR 600

The Cons:

  • No sRGB mode

About The Monitor

Interested in an ultrawide display? Meet the Dell Alienware AW3821DW with a 144Hz refresh rate and a 38″ 3840×1600 IPS screen!

Image Quality

A 38″ 3840×1600 ultrawide gaming monitor provides you with a high pixel density of 110 PPI, which results in sharp details and plenty of screen space without the need to use scaling.

The ultrawide aspect ratio also offers a wider FOV (field of view) in compatible games, which results in a more immersive gaming and viewing experience.

The extra horizontal screen space is also great for productivity work and audio/video editing.

Further, the Dell AW3821DW has a high 600-nit peak brightness, a wide 95% DCI-P3 color gamut, 32 dimming zones and a 1,000:1 static contrast ratio.

Sadly, it doesn’t have an sRGB emulation mode. So, if you need accurate sRGB color output, you’ll need a colorimeter.


Gaming features include Dark Stabilizer (for better visibility in darker games) and various pre-calibrated picture presets.

Design & Connectivity

Dell Alienware AW3821DW Monitor Design

The stand is quite sturdy as well as versatile. You can elevate the screen by up to 130mm, swivel by +/- 20°, tilt by -5°/21°, or VESA mount it via the 100x100mm pattern.

Connectivity options include DisplayPort 1.4, two HDMI 2.0 ports (limited to 85Hz), a quad-USB 3.0 hub and a headphone jack.


  • Acer Predator X35 – A 35″ 3440×1440 200Hz G-SYNC ultrawide monitor that offers a better HDR image quality due to its 512-zone local dimming solution. However, it uses an old VA panel with a slower response time speed. It goes for ~$2000, so if you want a true HDR ultrawide monitor, we recommend waiting for a mini LED version or alternatively, an OLED display.
  • Samsung Odyssey Neo G9 – A 49″ 5120×1440 240Hz 32:9 super-ultrawide gaming monitor based on a fast VA panel with a 2048-zone mini LED backlight. However, it doesn’t have a dedicated G-SYNC module and it’s currently suffering from some driver/firmware issues.


That’s it! Did you find the best G-SYNC monitor for you? If not, leave us a question below!

Overall, you can’t go wrong with the Dell Alienware AW3821DW or the ASUS PG32UQX, that is, if you can afford one of them!

For competitive gamers out there, the Dell AW2521H (or the Acer XV252QF with FreeSync) is the obvious choice, while those who want a good balance between image quality and performance, should get the ASUS PG279QM.
