Acer's Blisteringly Fast 4K, 144Hz HDR Gaming Monitors Cost Far Less Than Rival Displays

The Acer Predator XB273K supports G-Sync, while the Acer Nitro XV273K supports FreeSync.

Consider the 60Hz barrier for ultra–high-definition screens officially broken. Acer announced not one, but two new 4K, 144Hz gaming monitors at IFA in Berlin, for folks who like their frame rates high and temperatures low. One, the $1,299 Predator XB273K, supports Nvidia’s gameplay-smoothing G-Sync technology. The other, the $899 Nitro XV273K, plays nice with AMD’s rival FreeSync tech.

On paper, the Predator XB273K matches many of the key specifications of Acer’s Predator X27, a $2,000 display that we dubbed the Holy Grail of gaming monitors (see page 29) in our review. It’s got 4K resolution, a blazing-fast 144Hz maximum refresh rate (though that’s probably when overclocked), G-Sync, and even Display HDR 400 certification.
