Best G-SYNC Gaming Monitor: ViewSonic Elite XG270QG
The best gaming monitor with native G-SYNC support that we've tested is the ViewSonic Elite XG270QG. It's an excellent gaming monitor with a 27 inch screen and a 1440p resolution. Input lag is exceptionally low, and enabling VRR doesn't increase it all that much. The response time at max refresh rate is fantastic, and it remains excellent even when gaming at 60Hz. It has a backlight strobing feature to improve motion clarity, but you can't use it with VRR enabled, and the flickering might be bothersome to some people.
It's a fairly versatile monitor with good performance overall. It's well-built, and it has good ergonomics so that you can place the screen in an ideal viewing position. It has wide viewing angles, making it great for co-op gaming, and it provides good visibility in well-lit rooms thanks to its great reflection handling and high peak brightness. It has a few extra features, like built-in speakers, RGB bias-lighting, and a USB hub so that you can charge your devices while gaming.
Sadly, our unit has terrible out-of-the-box color accuracy, so you may need to get it calibrated to enjoy it to the fullest. That said, this can also vary between units. It also can't display very deep blacks, and our unit has poor black uniformity, so it's not the best choice for a dark room. Overall, if having native G-SYNC support is important to you, this is one of the best PC gaming monitors we've tested.
