The 3 Best G-SYNC Monitors - Fall 2024

The Dell Alienware AW3423DW is the best G-SYNC monitor that we've tested. It's an ultrawide display with a 34-inch screen and 3440x1440 resolution. This is ideal if you like playing FPS or atmospheric games with more horizontal screen space than a traditional 16:9 monitor. It offers fantastic gaming performance with a near-instantaneous response time that results in incredibly sharp motion at any refresh rate. It also has a max refresh rate of 175Hz, which you can achieve with a DisplayPort connection.

On top of its remarkable gaming performance, it delivers exceptional picture quality, thanks to its QD-OLED panel with near-infinite contrast and no blooming. It also displays a wide range of colors and gets bright enough for highlights to pop in HDR. However, it doesn't get bright enough to fight a lot of glare in a well-lit room, so if that's important for you, consider the LG 34GP950G-B. It gets brighter than the Dell, but also has worse picture quality as it doesn't display the same deep blacks, and motion isn't as sharp either.

If you don't like the ultrawide format of the Dell Alienware AW3423DW and you prefer a smaller 27-inch model, there are some options you can get in this size range. One is the ASUS ROG Swift PG279QM, which doesn't deliver the same outstanding picture quality as the Dell because it doesn't have a QD-OLED panel, so blacks look gray in the dark. On the other hand, one advantage is its higher 240Hz refresh rate, which is great for competitive gaming, and its 1440p resolution delivers enough details in games. However, if you want an even higher 360Hz refresh rate, consider the ASUS ROG Swift 360Hz PG27AQN, but it costs more.

The PG279QM is a good gaming monitor with a fast response time that remains consistently fast, no matter the refresh rate you're gaming at. Unlike the Dell model, it supports NVIDIA Reflex Latency Analyzer, which helps identify which sources cause the most delay in your gaming setup. However, you need a compatible mouse for it to work.

If you don't care about having a large screen, there are smaller G-SYNC monitors with refresh rates higher than the 240Hz on the ASUS ROG Swift PG279QM. If that's what you're interested in, the ASUS ROG Swift Pro PG248QP is a good choice for competitive esports gaming with an incredibly fast 540Hz refresh rate and 24-inch screen. It has a lower 1080p resolution than the PG279QM, so images aren't as detailed, but that means it's easier for your graphics card to maintain high frame rates.

One of the main advantages of using this monitor for gaming is that it has an incredibly fast response time, better than most other LED-backlit monitors, especially at high refresh rates. This means that motion looks incredibly sharp without much blur, but there's more blur as the refresh rate drops. It also uses NVIDIA's ULMB 2 backlight strobing feature to reduce persistence blur, but it only works between 360Hz and 540Hz.
