The 3 Best G-SYNC Monitors - Winter 2025

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, resulting 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 want the ultrawide format of the Dell Alienware AW3423DW, there are a few more options you can get with a smaller screen, like the 24-inch ASUS ROG Swift Pro PG248QP. While it doesn't have the premium picture quality of the Dell, as its TN panel has a low contrast ratio, it has a few other advantages, particularly if you're an esports gamer. It has a much higher 540Hz refresh rate, which is ideal for competitive gamers, and its 1080p resolution makes it easier for your graphics card to maintain high frame rates.

Another advantage 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 it still isn't as sharp as the Dell, and there's more blur at low refresh rates. Luckily, it uses NVIDIA's ULMB 2 backlight strobing feature to reduce persistence blur, but it only works between 360Hz and 540Hz.

If you feel the 24-inch screen of the ASUS ROG Swift Pro PG248QP is too small for your needs, consider a 27-inch option, like the ASUS ROG Swift PG279QM. While it doesn't have the same high 540Hz refresh rate as the PG248QP and has worse motion handling, it offers more of a balanced gaming experience in terms of pure performance and picture quality. Its 1440p resolution delivers more detailed images than on the PG248QP, and it also has better picture quality with more accurate colors and wider viewing angles.

Besides that, its response time remains consistently fast across its refresh rate range, and there's minimal blur with fast-moving objects. It also 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.
