Gaming monitors have evolved over recent years. The advent of variable refresh rate technologies has drastically improved the gaming experience. There are two competing VRR technologies: AMD's FreeSync and NVIDIA's G-SYNC technology. Although this is becoming less important as technology improves, your monitor should match the capabilities of your graphics card for the best VRR experience. Even though NVIDIA now supports Adaptive Sync with FreeSync monitors, they don't perform as well as native G-SYNC monitors. Learn more about NVIDIA's new G-SYNC compatible monitors here.

We've tested over 210 monitors, and below are our recommendations for the best G-SYNC monitors to buy. Check out our recommendations for the best monitors, the best gaming monitors, and the best curved gaming monitors.


  1. Best G-SYNC Monitor: ViewSonic Elite XG270QG

    8.5
    Gaming
    Size 27"
    Resolution 2560x1440
    Max Refresh Rate

    Variable Refresh Rate
    G-SYNC

    The best G-SYNC monitor that we've tested is the ViewSonic Elite XG270QG. It has a 27 inch screen with a 1440p resolution, which means you get plenty of screen real estate and a sharp image for an immersive gaming experience. It has great reflection handling and gets pretty bright, and it even includes anti-glare panels in the box if you need better shielding from bright lights. The stand allows for all manner of adjustments so that you can get a comfortable viewing position or share the screen with someone else.

    It has a native 144Hz refresh rate you can overclock up to 165Hz and an exceptional response time, which results in a very clear image with only a short blur trail behind fast-moving objects. In addition to its native G-SYNC support, it's also compatible with FreeSync, so you don't have to worry about being limited to NVIDIA GPUs when it comes time to upgrade. It has a black frame insertion feature to improve motion clarity, but it isn't usable while VRR is active.

    Unfortunately, there's no HDR support, which might disappoint some gamers. Also, it has a sub-par contrast ratio that makes blacks look grayish in the dark, which is expected for most IPS panels. You'll likely need to calibrate it if you plan on using it for content creation because color accuracy is quite bad out of the box. Overall, it's a great gaming monitor, as long as you don't care about HDR.

  2. HDR Alternative: Dell Alienware AW2721D

    Size 27"
    Resolution 2560x1440
    Max Refresh Rate
    240 Hz
    Pixel Type
    IPS
    Variable Refresh Rate
    G-SYNC

    If you want a monitor that supports HDR, then check out the Dell Alienware AW2721D. Like the ViewSonic Elite XG270QG, it's also a 27 inch IPS monitor with a 1440p resolution. However, it has HDR and wide gamut support, and it can get pretty bright to make highlights pop. That said, it also has a low contrast ratio that makes blacks appear gray in the dark, and its edge-lit local dimming performs terribly. It has a higher refresh rate, but the difference between 165Hz and 240Hz might not be noticeable to most casual gamers, and it requires high-end hardware to reach frame rates that high.

    Overall, go with the ViewSonic if you don't care about HDR. However, if you want HDR support and don't mind paying more, go with the Dell.

  3. Best 360Hz G-SYNC Monitor: Dell Alienware AW2521H

    8.6
    Gaming
    Size 25"
    Resolution 1920x1080
    Max Refresh Rate
    360 Hz
    Pixel Type
    IPS
    Variable Refresh Rate
    G-SYNC

    The Dell Alienware AW2521H is the best G-SYNC monitor with a 360Hz refresh rate we've tested. This compact 25 inch monitor is amazingly well-built and comes with a stand that offers plenty of ergonomic adjustments. It has wide viewing angles, making it great for playing co-op games, and it gets very bright, enough to provide good visibility in well-lit settings. Its contrast ratio is better than most IPS panels, but blacks still look grayish in the dark.

    Its highlight feature is its incredible responsiveness. It has exceptionally low input lag and a 360Hz refresh rate, making every action feel nearly instantaneous. It has a superb response time to deliver clear motion, and of course, G-SYNC support to reduce screen tearing. It has a black frame insertion feature to improve motion clarity; however, it isn't usable while VRR is enabled and only works within a narrow refresh rate range.

    There's HDR support, but the overall experience is only okay because it lacks a wide color gamut, and its HDR brightness is only decent. Also, it has a mediocre contrast ratio that causes blacks to appear gray when viewed in the dark and lacks a local dimming feature. It has a unique feature called NVIDIA 'Reflex', which measures input lag and provides ways to improve it. All in all, it's a fantastic gaming monitor that should please even the most serious esports gamers.

  4. Best Ultrawide G-SYNC Monitor: LG 34GP950G-B

    8.4
    Gaming
    Size 34"
    Resolution 3440x1440
    Max Refresh Rate
    180 Hz
    Pixel Type
    IPS
    Variable Refresh Rate
    G-SYNC

    The best G-SYNC monitor we've tested with an ultrawide screen is the LG 34GP950G-B. It has a 34 inch screen with a 21:9 aspect ratio, which gives you more horizontal space than a standard 16:9 display. This wider field of view is great for game immersion, and you also get plenty of screen real estate for multitasking. It has decent viewing angles, and it gets bright enough to overcome glare. The stand only allows height and tilt adjustments, but you can VESA mount it if you need greater adjustability.

    The response time is exceptional, whether you play at its maximum refresh rate of 180Hz or 60Hz, so fast motion looks incredibly smooth and clear. Although it's a native G-SYNC monitor, it still supports FreeSync, which is great as you can continue using it should you decide to upgrade to an AMD graphics card in the future. It has outstanding DCI P3 coverage and good peak brightness for HDR, but its contrast ratio is sub-par, and its edge-lit local dimming performs terribly.

    Feature-wise, you get a USB hub with two USB 3.0 ports so that you can plug your peripherals, or wireless dongles, directly into the monitor. You can add a virtual crosshair or frame rate indicator on the screen, and there's also a black stabilizer feature that makes objects easier to see in dark scenes. Overall, this is an impressive gaming monitor that should make most people happy.

  5. Cheaper Alternative: Dell AW3420DW

    Size 34"
    Resolution 3440x1440
    Max Refresh Rate
    120 Hz
    Pixel Type
    IPS
    Variable Refresh Rate
    G-SYNC

    If you find the LG 34GP950G-B too expensive, consider the Dell Alienware AW3421DW. It's also a 34 inch model with a 3440 x 1440 resolution and 21:9 aspect ratio. However, it has a lower refresh rate of 120Hz, and it doesn't support HDR. Its response time is slower but still excellent, so fast motion still looks clear with almost no blur trail behind moving objects. Unfortunately, it doesn't get very bright, so it's best suited for a moderately lit room as glare might be an issue. On the upside, it has better ergonomics because it allows for swivel adjustment, and it has two more USB ports.

    Overall, the LG is a better choice because it has a higher refresh rate, faster response time, and supports HDR. However, the Dell is a good alternative if you're on a tighter budget, as long as you don't mind a few compromises.
