The XB271HU by Acer Predator is again available on a lower deal from Amazon, as you can get an 1440p, 165Hz OC refresh rate, and 144Hz native refresh rate with G-Sync technology support for only $524. This deal should last for the coming weeks, and if you're in need of a new gaming monitor then this Predator XB271 is worth a look.
Acer Predator XB271HU offers the following specs: 27-inch IPS monitor, 2560 x 1440 screen resolution, 144hz refresh rate, NVIDIA G-Sync technology, 4ms GtG response time, 350nits brightness, two 2W audio speakers, DisplayPort, HDMI, USB 3.0 upstream and four USB 3.0 downstream inputs. The 165Hz refresh rate is only available via DisplayPort input. Also, note that the NVIDIA G-Sync technology is available with a GPU that supports such technology and with the latest NVIDIA GeForce drivers installed.
If you need to buy a new 27-inch monitor and you wish to game at 1440p with high refresh rates, then the Acer Predator XB272HU provides excellent gaming performance with low input lag and more than decent color quality. Currently, the pricing of this monitor is set at $524, which is a fair price considering all the features and the fast IPS panel that is offered by it.
