Acer's latest monitor might be perfect for the gamers out there rocking one of Nvidia's latest high-end GPUs. The XB280HK is a 28-inch TN display sporting a resolution of 3,840 x 2,160 (4K Ultra HD), and is fully compatible with Nvidia's G-Sync adaptive refresh rate technology.

Thanks to DisplayPort 1.2 this panel is capable of displaying 4K at 60 Hz, and with G-Sync it will be able to alter its refresh rate on the fly to reduce stuttering and tearing in games. This is especially important when gaming at 4K, because most GPUs struggle to render the latest games at 60 frames per second.

The stand Acer is using supports adjustable height, tilt and swivel, allowing you to use the monitor in portrait if you like. There's also a typical contrast ratio of 1000:1, 300 cd/m2 brightness, and a 1ms gray-to-gray response time. Like many DisplayPort monitors, the XB280HK has a USB 3.0 hub on board.

With the price of Ultra HD monitors having come down significantly over the past year, it's not surprising to find that Acer's offering will retail in the US for just $800, with pre-orders starting today. Competing 4K monitors of the same size currently cost around $600, so you're paying a $200 or so premium for G-Sync support.

Announced alongside the 28-inch 4K monitor was a 27-inch 1080p 144 Hz model also boasting G-Sync. Specifications for this monitor are pretty similar to the Ultra HD model, and has already hit retail shelves with a $600 price tag.
