The LG 34U640B-B pairs a 34-inch VA panel with a 3440 × 1440 resolution. Its Wide Quad HD image uses a 21:9 native aspect ratio, providing a broad workspace for side-by-side windows. A 144 Hz maximum refresh rate supports smooth motion in scrolling and compatible games. The rated response time is 5 ms. Typical brightness is 300 cd/m², while the 4000:1 typical contrast ratio maintains separation between dark and light content.
Colour reproduction covers 99% of sRGB, and the screen can display approximately 1.07 billion colours. Horizontal and vertical viewing angles are both rated at 178°, allowing some flexibility when viewing from off-centre positions. HDR support includes HDR10 and HDR Effect processing. The 1800R curved screen keeps its wide outer edges within a more consistent field of view. An anti-glare surface, flicker-free technology and a low-blue-light mode address reflections and extended viewing comfort.
Connectivity comprises two HDMI 2.0 inputs and one DisplayPort 1.4 input. The stand provides up to 100 mm of height adjustment plus a -5 to 20° tilt range. A 100 × 100 mm VESA interface supports an alternative monitor arm or wall mount. With the stand fitted, the monitor measures 810.26 mm wide and weighs 7711 g. It is rated energy class F for SDR and G for HDR, with respective consumption figures of 30 kWh and 39 kWh per 1,000 hours.
