The 34-inch UltraWide screen 34WR55QC, unveiled last year and available since 2024, is now getting a successor. The new LG 34WR55QK UltraWide monitor with USB-C retains the exact specifications.

LG QHD monitor with HDR support features a 34-inch VA panel with UWQHD resolution (3440 x 1440 pixels, 21:9 aspect ratio), a 100 Hz refresh rate, a 3000:1 contrast ratio, 99 percent sRGB color coverage, 8-bit color depth, a 5 ms gray-to-gray response time, and a typical brightness of 300 cd/m².
The main improvement is the enhanced energy efficiency. According to the EU energy label, the new 1800R curved USB Type-C work monitor consumes 28 watts instead of 31 watts (SDR) and 45 watts instead of 48 watts (HDR).
The 34WR55QK still includes features like an auto input switch, HDR10 support, picture-by-picture mode, and a black stabilizer. However, the information provided does not mention whether the 34WR55QK supports FreeSync functionality for preventing screen tearing, which is available in the 34WR55QC.
When it comes to interfaces, the monitor once again offers two HDMI inputs, a DisplayPort, a USB 3.0 hub, a headphone output, and USB-C with DisplayPort alternate mode and 65-watt PD. Moreover, its ergonomic features include tilt and height adjustment, VESA mount compatibility (100 x 100 mm), blue light filtering, flicker-reduced backlighting, and a specialized mode for individuals with color vision deficiency.
