The Good: The Acer Predator XB272 delivers a handy 240Hz maximum refresh rate in addition to G-Sync support and offers a decent selection of hardware controls. The Bad: Its resolution is pretty low for a 27-inch monitor, and its input connectors aren't up to the latest standards. The Bottom Line: If you just need it for high-frame-rate gaming, the Acer Predator XB272 is a great option. But otherwise it's a bit lackluster for the money as a general-purpose monitor. Acer raises the bar for high frame-rate gamers, extending its 25-inch Predator XB252 up to 27 inches and bringing with it a maximum refresh of 240Hz. At $680 (approximately \u00a3620, AU$1,050) It's not the cheapest G-Sync monitor around, but at the moment it's one of the few to refresh that fast. And for a TN panel, it's pretty good.(Don't confuse this with the as-yet-unavailable XB272-HDR, which has a completely different panel.) The trade-off, though, is resolution, which is also the same as the smaller panel. That means you can drive a truck between the pixels -- OK, not really, but it does mean that for doing things other than playing games it's not very sharp. For games, you can use G-Sync DSR to increase the perceived resolution. The XB272's layout is pretty typical, with onscreen display controls on the back right. The buttons are a little flat and hard to feel, but they're supplemented by a joystick that makes it much easier to navigate the menus than typical up- and down-arrow buttons. You can map two of the buttons directly to menu options, a nice perk. It has a reasonably broad set of options. Among the various presets there are three gaming-specific ones that change the brightness, refresh rate and white point settings. There's also a selection of three optional target overlays, adaptive contrast, and a decent set of display options for color and brightness.
