This is the monitor you get when you want your games to feel buttery smooth without spending a fortune. It refreshes 240 times per second, which is fast enough for competitive shooters where split-second reaction times matter. Pixels change color instantly, so you won't see ghosting trails behind moving objects.
The trade-off is resolution. At 27 inches, 1080p means the picture isn't as sharp as a phone screen — text has visible jaggedness and details in games look softer than they would on a 1440p monitor. It's fine if you sit arm's length away and care more about frame rates than crisp edges, but side-by-side with a sharper screen the difference is obvious.
BenQ calls it HDRi but that's a custom brightness mode, not real HDR. The colors look decent for an IPS panel and there's enough brightness for a lit room.
