The 5 Best G-SYNC Monitors - Winter 2021 Reviews

The best G-SYNC monitor we've tested is the ViewSonic Elite XG270QG. This is a well-built model with a style that fits into any office or gaming setup. The stand offers good ergonomics, and you shouldn't have any issues placing it in an optimal viewing position.

It offers excellent gaming performance. Its native 144Hz refresh rate can easily be overclocked to 165Hz, and the G-SYNC support allows it to drop to 20Hz, and like most monitors, it only supports VRR over a DisplayPort connection. It has an outstanding response time at its max refresh rate that stays really quick even at 60Hz. It has a Black Frame Insertion feature to help clear up motion blur, but it can't be used with G-SYNC enabled. Input lag is incredibly low, and even though it increases at 60Hz, it shouldn't be noticeable to most people. The 1440p resolution delivers clear and crisp images, and the IPS panel has wide viewing angles, making it an ideal choice for co-op gaming.

Unfortunately, it doesn't support HDR, and our unit has bad out-of-the-box color accuracy, but this may vary between units. It also has a low contrast ratio, which is expected from an IPS panel. It has great extra features like a USB hub, built-in speakers, and RGB lighting on the back to set the mood in your gaming setup. There isn't much to complain about, making it the best G-SYNC monitor we've tested.

The best G-SYNC monitor with a 360Hz refresh rate that we've tested is the Dell Alienware AW2521H. Although it has a smaller 25 inch screen and a 1080p resolution, it delivers an incredibly responsive gaming experience, enough to satisfy serious esports players. It has an excellent build quality, great ergonomics, and a sleek design that fits easily into most settings. It has an IPS panel with wide viewing angles, so images remain accurate when viewed from the side, great for sharing content or playing co-op games.

Its motion handling is superb. It has an exceptionally fast response time with virtually no overshoot that can cause motion artifacts, and it has a whopping 360Hz refresh rate. It has a Black Frame Insertion feature that can further reduce motion blur; however, it can't be used simultaneously with VRR, and it only works within a narrow frequency range. It supports HDR, but like most monitors, it doesn't get bright enough for HDR content and can't display a wide color gamut.

While its IPS panel's wide viewing angles are great, it does come at the cost of a lower contrast ratio, which means that it isn't well-suited for dark rooms. On the flip side, it fights glare easily and provides great visibility in bright rooms. You can add a virtual crosshair or a frame rate counter on the screen, and there are four USB ports for charging. So, if you want the fastest monitor for the most responsive gaming experience, and you don't mind a smaller screen or a 1080p resolution, this one is worth checking out.

The best G-SYNC monitor with an ultrawide screen is the Dell Alienware AW3420DW. This is a well-built model, and despite its large size, it has a decent stand that allows for a wide swivel and tilt range. It can't rotate to portrait mode, although that's somewhat expected due to its ultrawide format and curved screen.

It has a native 120Hz refresh rate, and it supports Adaptive Sync, allowing you to use Free Sync when connected to a compatible source over a DisplayPort connection. The response time at its max refresh rate is excellent, resulting in minimal motion blur, and it's also great at 60Hz. Sadly, it doesn't have a Black Frame Insertion feature to clear up motion blur. Its input lag is also really low, and it stays low with VRR enabled, which is great. It has an IPS panel that provides wide viewing angles, and if you also want to use it for photo editing, it has an outstanding color gamut with excellent coverage of the Adobe RGB color space.

Unfortunately, it has a low contrast ratio, so blacks appear gray when viewed in the dark. It also doesn't support HDR, and if you want to use it in really bright rooms, it doesn't get bright enough to combat glare, thanks to its mediocre reflection handling. Regardless, it has some nice extra features like RGB lighting and a USB hub. All in all, this is the best G-SYNC monitor in the ultrawide category that we've tested.
