LG Electronics Japan has introduced the UltraFine Display 40U990A-W, a 39.7-inch ultra-wide curved monitor equipped with a 5K2K resolution and Thunderbolt 5 support. This 21:9 aspect ratio display offers 33% more screen space than standard 4K monitors, making it ideal for content creators, multitaskers, and gamers.
The monitor delivers a resolution of 5120 x 2160 on a 2500R curved Nano IPS Black panel. It boasts a 2000:1 contrast ratio and covers 99% of the DCI-P3 color gamut. Certified with VESA DisplayHDR 600, it ensures vivid visuals and deeper blacks. LG’s Live Color Low Blue Light technology reduces eye strain while maintaining color accuracy.
The 40U990A-W is the first PC monitor to support Thunderbolt 5. This allows for 120 Gbps bi-directional data transfer, 96W power delivery, and daisy chaining of two monitors at a combined resolution of 10240 x 2160 at 120Hz. In terms of connectivity, it includes four USB-C ports (10Gbps), two USB-A ports, and a LAN (RJ45) port for stable networking.
For multitasking and efficiency, it includes a KVM switch, allowing two PCs to share one keyboard, mouse, and set of USB peripherals. It also supports Picture-by-Picture (PBP) and Picture-in-Picture (PIP) display modes. Gamers will benefit from features like Variable Refresh Rate (VRR), AMD FreeSync Premium, Dynamic Action Sync, and Black Stabilizer.
The monitor is equipped with 10W + 10W Rich Bass built-in speakers and an ergonomic stand offering 130mm height adjustment, tilt from -5° to 20°, and 20° swivel.
