The 3440 x 1440 resolution offers some attractive benefits for both work and play. Models like the LG 34GK950F combine this with a high resolution and variable refresh rate technology. The LG 34GN850 (34GN850-B owing to the black rear and stand neck) is the followup to this model. The monitor features a dual-stage bezel at the top and sides. There’s a reasonably slender panel border that’s flush with the rest of the screen, plus a hard plastic outer component. The bottom bezel is reasonably slim, with a hard matte black plastic bezel covering most of the panel border. The OSD (On Screen Display) is controlled by a joystick at the bottom of the monitor, beneath the central LG logo.

A subtle gaming aesthetic

A curved 34″ 3440 x 1440 (21:9 UltraWide) Nano IPS panel is adopted. This features a light matte anti-glare screen surface, 1000:1 static contrast ratio and 178° horizontal and vertical viewing angles. A 160Hz refresh rate is supported via a factory overclock, with the panel offering a native 144Hz refresh rate. Adaptive-Sync is supported, including AMD FreeSync Premium and Nvidia ‘G-SYNC Compatible Mode’. The monitor is certified as compatible with both technologies. A variable refresh rate range of 48 – 160Hz is offered, alongside LFC (Low Framerate Compensation). 10-bit colour is supported (8-bit + FRC most likely), although you’ll be restricted to using a reduced chroma (4:2:2) signal or 8-bits per channel at 160Hz. The flicker-free WLED backlight with enhanced phosphor ‘Nano’ coating is used, with a 98% DCI-P3 colour gamut and 400 cd/m² typical maximum luminance. The monitor is VESA DisplayHDR 400 certified, the lowest level of HDR specification that VESA certifies for. It allows the monitor to respond to HDR10 content, a 10-bit colour signal can be used and the generous colour gamut can be put to good use. The standard does not require effective local dimming and the maximum luminance is relatively restrictive for HDR.

Other noteworthy features include Low Blue Light (LBL) settings including ‘Reader Mode’, to enhance viewing comfort. ‘Dynamic Action Sync’ (DAS), designed to automatically reduce input lag (i.e. always enabled) and a 1ms grey to grey response time. You should certainly take that figure with a heavy dose of salt, however. A ‘Black Stabilizer’ feature is included to enhance visibility in dark areas alongside an on-screen crosshair function. The included stand attaches using a quick-release mechanism and includes tilt and height adjustment. It can be removed to reveal 100 x 100mm VESA holes for alternative mounting, if preferred. The ports face backwards and are located in a recessed area to the right of the stand attachment point. These include; DP 1.4, 2 HDMI 2.0 ports, 2 USB 3.0 ports (plus upstream), 3.5mm headphone jack and DC power input (external ‘power brick’).

Mainly black, with a hint of red

Further details can be found on certain regional manufacturer product pages. The monitor is available for ~£1000 ($1000 USD).
