The 124.5 cm ultra-wide screen with DQHD resolution and 1800R curvature provides a broad field of view and enhanced depth for both work and entertainment. The monitor uses a VA panel with a wide color gamut (99% sRGB, 85% NTSC) and average color accuracy of ΔE < 2. It includes built-in speakers, VESA mounting, an ergonomic adjustable stand, and multiple connectivity options such as USB-C with up to 65 W power delivery and an RJ-45 port.

Advantages

The LM49-EW410CA displays detailed visuals across a very wide workspace, making it easy to view large spreadsheets, multiple application windows, or expansive game maps simultaneously. Its 1800R curved screen and VA panel offer consistent contrast (typ. 3000:1) and accurate color reproduction for clearer images. USB-C simplifies connections to laptops, smartphones and tablets while supporting screen sharing and device charging. Additional features such as Picture-by-Picture (PBP), flicker-free technology, blue light reduction mode and built-in speakers increase usability for mixed office and multimedia use.

How to use

Place the monitor on a stable surface or mount it using the VESA interface. Connect your source devices using USB-C to enable screen sharing and up to 65 W charging, or use available video inputs and the RJ-45 port for network access if needed. Use the on-screen display to enable Picture-by-Picture (PBP) when working with two input sources simultaneously, adjust brightness and activate blue light mode to reduce eye strain, and set the ergonomic stand position for comfortable viewing.

Recommendations

For best results position the curved monitor centrally at eye level and maintain a viewing distance that matches the 1800R curvature. When using laptops without Ethernet ports, connect via the RJ-45 port to ensure a stable wired network. Enable blue light mode and flicker-free settings during extended use to reduce visual fatigue.
