The 27UL550-W 27' 16:9 4K HDR FreeSync IPS Gaming Monitor from LG is built with an IPS (In-Plane Switching) panel, which provides you with wide viewing angles and vivid colors. Furthermore, it comes color-calibrated from the factory to ensure colors are accurate. Specs-wise, it has a 3840 x 2160 4K UHD resolution, a 1000:1 static contrast ratio, a 300 nits brightness rating, and support for up to 1.07 billion colors. Thanks to AMD Radeon FreeSync technology, which helps to reduce screen tearing, stuttering, and ghosting, you'll be able to enjoy a fluid gaming experience. Connect it to your system via HDMI or DisplayPort and adjust its versatile stand to best suit your viewing preference. You can also install an optional VESA-compatible mount, stand, or arm if needed.
