Overview

The LG 34WR55QK-B is a 34-inch curved ultrawide monitor built for professionals and multitaskers who want to consolidate their workspace onto a single screen. Its 3440 x 1440 WQHD resolution across the 21:9 aspect ratio delivers roughly 33% more horizontal pixels than a standard QHD display, making it well suited for working with large spreadsheets, editing timelines, coding with multiple panes, or simply keeping reference material open alongside your primary application. The 1800R curvature wraps the expanded field of view gently around your peripheral vision, reducing the need to turn your head at the screen's edges.

Beyond the panel itself, the monitor is thoughtfully equipped for modern workflows. The USB Type-C input supports up to 65W power delivery, so a single cable can drive the display and charge a compatible laptop simultaneously. LG's OnScreen Control software adds practical workspace management tools, including the ability to split the screen into preset zones or run Picture-by-Picture mode with two independent sources. The 100Hz refresh rate and HDR10 support add smoothness and vibrancy that benefit everyday use, while the height- and tilt-adjustable ergonomic stand and three-sided borderless design keep the setup looking clean and feeling comfortable over long sessions.

👎 Cons

Curved VA-type panel may exhibit slight color shift at extreme viewing angles compared to flat IPS alternatives
100Hz refresh rate is adequate for productivity but falls short for competitive gaming compared to higher-refresh monitors
At 34 inches, the ultrawide form factor requires a deep desk to maintain a comfortable viewing distance
65W USB-C power delivery may not be enough to charge larger or more power-hungry workstation laptops at full speed
