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 and their price.

About The Monitor

Want the best 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.

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.


MSI, ASUS, Acer, and Dell-Alienware all offer 360Hz gaming monitors based on the same panel.

Depending on the region, availability, and your personal preference of design and features, you should check them out as well.

The Pros:

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

The Cons:

  • No sRGB mode

About The Monitor

If you want a larger screen with a higher resolution, check out the Dell Alienware AW2721D.

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 Dell AW2721D.

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 98% DCI-P3 color gamut, which makes for vibrant and saturated colors, especially reds and greens.

Sadly, there’s no sRGB emulation mode that could restrict the monitor’s native ~135% sRGB gamut to ~100% sRGB for a more accurate color output.

So, sRGB content will have over-saturated colors. Some users actually prefer this as it makes the image more lively.

HDR content, on the other hand, will have simply gorgeous colors, just the way the developers intended.

On top of that, the monitor’s peak brightness goes up to 600-nits for HDR content and there are 32 dimming zones that can dim parts of the image that need to be dark, without affecting the bright areas.


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

The stand boasts premium build quality and versatile ergonomics with up to 130mm height adjustment, +/- 20° swivel, 90° pivot, -5°/21° tilt, and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.4, two HDMI 2.0 ports (limited to 144Hz), a headphone jack, an audio line-out port, and a quad-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 and low input lag
  • Fully ergonomic stand and rich connectivity options
  • DisplayHDR 1000

The Cons:

  • Expensive

About The Monitor

In case you can afford something pricier, the ASUS ROG Swift PG27UQ offers an amazing HDR viewing experience as well as responsive gameplay.

Image Quality

The 4K resolution results in even sharper details on 27″ 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 384-zone full-array local dimming (FALD) solution.

Unlike the 32 edge-lit zones on the Dell AW2721D, the ASUS PG27UQ has 384 zones across the entire screen allowing for better dimming control.

On top of that, the monitor has a stellar 1000-nit peak brightness and covers 97% of DCI-P3 and 99% of Adobe RGB color spaces.

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

Now, as there are 384 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 only 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 Dell AW2721D, the ASUS PG27UQ 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 include pre-calibrated picture prests, on-screen timers and crosshair overlays, and RGB lighting adjustments.

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 120mm height adjustment, 90° pivot, -5°/20° tilt, +/- 35° swivel, and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.4, HDMI 2.0, a headphone jack, and a dual-USB 3.0 hub. Note that DP 1.4 is limited to 8-bit color at 120Hz, and 10-bit color at 98Hz.

For 144Hz, you’ll need to use chroma subsampling, which makes text appear smudgy on colored backgrounds. As there’s no big difference between 144Hz and 120Hz, nor between 10-bit and 8-bit color, we recommend just using the monitor at 4K 120Hz.


  • Acer Predator X27 – Acer’s version of this monitor based on the same panel. The image quality and performance is pretty much the same, so you can just pick according to the price/availability or your personal preference of the design and features.
  • ASUS PG27UQX – The upcoming updated version of this monitor with Mini LED backlight and 576-zone local dimming for better HDR image quality.

The Pros:

  • 200Hz refresh rate
  • Good response time and low input lag
  • Fully ergonomic stand and rich connectivity options
  • DisplayHDR 1000

The Cons:

  • Expensive
  • Minor ghosting in darker scenes

About The Monitor

Interested in an ultrawide display? Meet the Acer Predator X35 with a 200Hz refresh rate and a 512-zone FALD solution!

Image Quality

A 35″ 21:9 ultrawide gaming monitor is basically as tall as a 27″ display (slightly taller, by ~1.5cm or 0.6″), but ~33% wider.

You also get 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 provides you with a wider FOV (field of view) in compatible games, which provides a more immersive gaming and viewing experience.

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

Further, the Acer X35 has a high 1000-nit peak brightness, a wide 90% DCI-P3 color gamut, and a 2,500:1 static contrast ratio.

In comparison to the PG27UQ, you don’t get quite as vibrant or consistent colors, but its higher contrast ratio makes for deeper blacks and more vivid details in shadows.

Some minor ghosting in fast-paced games will be noticeable, mostly in dark scenes where dark pixels transition into brighter shades, but it’s tolerable.


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

The stand is quite sturdy as well as versatile. You can elevate the screen by up to 130mm, swivel by +/- 30°, tilt by -5°/25°, or VESA mount it via the 100x100mm pattern.

Connectivity options include DisplayPort 1.4, HDMI 2.0 (limited to 100Hz), four USB 3.0 ports (3 downstream and 1 upstream), a headphone jack, and dual 4W built-in speakers.

Keep in mind that DP 1.4 is limited to 8-bit color at 180Hz and 10-bit color at 144Hz. For 200Hz, you’ll need to use chroma subsampling, so we recommend going with 180Hz.


  • ASUS ROG Swift PG35VQ – ASUS’ monitor based on the same panel. It offers a similar image quality and performance, so you can just pick according to whichever is cheaper or your design/feature preference.
