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 cd/m² 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.
