What We Like About the LG 34U640B

3440×1440 at 21:9: roughly 1.3× the horizontal working width of a standard 2560×1440 16:9 panel, so two full documents or app windows sit side by side without overlap
144Hz refresh rate: more than double the 60Hz a typical office monitor runs at, with AMD FreeSync Premium and VRR for variable-rate output
USB-C with 65W Power Delivery: carries display, data and laptop charging over one cable, so a notebook docks with a single connection
Dual Controller KVM: switches one keyboard and mouse between two connected PCs and supports drag-and-drop file transfer between them
