Ultrawide Display
The WQHD (3440×1440) display gives you room to work across multiple apps at once, reducing window switching and improving focus. The subtle 1800R curve follows your natural line of sight to keep long sessions comfortable, while the narrow-bezel design keeps the screen presentation clean and immersive.
Versatile Connectivity
Along with one DisplayPort and two HDMI inputs, the UltraWide features a USB-C port that is DP Alt Mode- and Power Delivery-capable. With just one USB-C cable, this allows you to display content, transmit data, and charge up to 65W.
Dual Device Ready
With the integrated KVM switch, you can control two PCs with a single monitor, keyboard, and mouse. Easily switch between devices and move files between systems with a simple drag-and-drop to streamline your setup and reduce desk clutter without extra hardware.
FreeSync Premium Technology
Powered by a FreeSync Premium certification, this monitor delivers tear-free, ultra-smooth visuals with low latency. As such, fast motion stays controlled, responsive, and visually precise during gameplay.
Reader Mode
Reader Mode reduces blue light, displaying warmer hues and tones ideal for reading documents or browsing for extended periods.
LG Switch App
The Switch app transforms your screen into a multitasking hub for work, gaming, and streaming. Effortlessly split the screen into up to six sections, customize display layouts, or launch video calls with a single hotkey.
