The 5 Best G-SYNC Monitors - Summer 2021 Reviews

The best G-SYNC monitor that we've tested is the ViewSonic Elite XG270QG. This is an impressive gaming monitor, with outstanding response times, even at a lower refresh rate. This means that fast-moving objects in your favorite games are clear with no noticeable blur behind them. It also has amazing low input lag for a responsive gaming experience. There are also a few extra features to improve your gaming experience, including a Black Frame Insertion feature and an option to add virtual crosshairs to the screen.

It looks great in bright settings, with good peak brightness and great reflection handling. Like most IPS monitors, it's not as well-suited for a darker environment, as blacks look gray in a dark room. It's also a great monitor for co-op gaming or sharing your screen with someone else, as the image remains accurate at an angle, and the stand has a good range of ergonomic adjustments.

It doesn't support HDR, but that's not unusual, and HDR doesn't add much for most monitors anyway. The unit we tested has bad out-of-the-box accuracy, which might disappoint some people, but this can vary between units. Overall, though, it's an impressive gaming monitor that should please even the most demanding gamers.

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.

The best G-SYNC monitor with an ultrawide screen is the LG 38GL950G-B. It's a 38 inch, 21:9 monitor that provides more horizontal screen space to deliver greater immersion. It has a 3840x1600 resolution, which comes out to the same pixel density as a 27 inch 1440p monitor, resulting in sharp images and text. It has good viewing angles, high peak brightness, and impressive color accuracy out of the box. The stand only offers tilt and height adjustments, so it's best to VESA-mount it if you want more adjustability.

It has an exceptional response time to deliver clear images in fast-moving scenes. It has low input lag, and you can overclock its 144Hz refresh rate up to 175Hz for even more responsiveness. It supports G-SYNC natively to reduce screen tearing and is compatible with FreeSync as well. It gets decently bright in HDR, enough to bring out some highlights in games, but not for a true cinematic HDR experience. Unfortunately, it's not the best option for dark room gaming due to its low contrast ratio.

While gaming on an ultrawide monitor is incredibly immersive, not all games support this format, so you might see black bars at the sides, or the image might stretch to fill the screen. There's a Picture-in-Picture/Picture-by-Picture mode that lets you display two input signals simultaneously, which can be helpful for multitasking or streamers running on two computers. All in all, it's an impressive gaming monitor that should make most people happy.
