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, as they usually lack some advanced features, including variable overdrive. For this article, we're only looking at monitors that natively support G-SYNC. Learn more about NVIDIA's new G-SYNC compatible monitors here.
We've tested over 220 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.
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's an amazing gaming monitor with a fast native refresh rate, an excellent response time, and incredibly low input lag. Of course, it natively supports NVIDIA G-SYNC technology, ensuring a visually consistent gaming experience at any refresh rate. However, it also works with FreeSync sources like an Xbox or AMD graphics card.
The IPS panel delivers wide viewing angles, so it's great for co-op gaming, and visibility isn't an issue thanks to its great reflection handling and very good peak brightness, so glare isn't an issue. It also has an optional backlight strobing feature, commonly called black frame insertion (BFI), which can improve the appearance of motion, but like most monitors, you can't use it simultaneously with the variable refresh rate feature.
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. Overall, it's a great gaming monitor, as long as you don't care about HDR.
If you want a monitor that supports HDR, 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.
The Dell Alienware AW2521H is the best G-SYNC monitor with a 360Hz refresh rate we've tested. It's an excellent gaming monitor with an incredible response time, resulting in extremely clear motion, with almost no noticeable blur behind fast-moving objects and no overshoot in our recommended overdrive mode. It also has exceptionally low input lag, meaning you can respond quickly to the action on-screen.
The relatively low resolution isn't great for multitasking or office use, but it's ideal for fast-paced competitive gaming, as it's less demanding on your computer hardware. Of course, it also supports G-SYNC variable refresh rate technology (VRR) natively, but unlike most monitors, it's not compatible with FreeSync sources at all, so it's not a good choice for gamers with AMD graphics cards. It also has an optional backlight strobing feature, commonly known as black frame insertion (BFI), but it can't be used with VRR enabled.
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 we've tested with an ultrawide screen is the LG 34GP950G-B. Part of LG's UltraGear lineup of gaming monitors, it delivers an impressive gaming experience, with an extremely fast response time at any refresh rate, outstanding low input lag, and, of course, G-SYNC support. It's also compatible with FreeSync sources, including computers with AMD graphics cards, but it's not ideal for console gamers, as the ultrawide aspect ratio isn't supported on those devices.
The ultrawide 21:9 aspect ratio delivers a more immersive gaming experience, assuming your favorite games support it. It provides a wider field of view, so you can see more of what's going on around you. Sadly, it doesn't have a backlight strobing feature, commonly known as black frame insertion (BFI), but since it already has incredibly clear motion, it's not that disappointing.
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.
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.
