Based on a 24-inch TN-panel with 2560x1440 resolution, the Acer Predator XB241YU has 144Hz standard refresh rate, "overclockable to 165Hz", 1ms response time and 350 nit of maximum brightness. It also uses a new ZeroFrame design, which makes the bezels as thin as possible, making it suitable for multi-monitor setups.
As noted, the Acer Predator XB241YU features support for Nvidia G-Sync and includes a four port USB 3.0 hub, 2W stereo speakers as well as comes with a stand that allows height, tilt and swivel adjustments. It features HDMI and DisplayPort 1.2 inputs, which is needed for Nvidia G-Sync technology.
According to Acer, the Predator XB241YU monitor should be already available with a price set US $499.99, which is a rather neat price for a G-Sync enabled monitor.
