Further information on supporting our work.The ‘4K’ UHD resolution provides a good amount of desktop real-estate and detail to suitably high resolution content. The LG 27UP850 (27UP850-W owing to white rear) offers this experience, with some additional attractive features such as strong ergonomic flexibility and USB-C connectivity. The monitor has a homely design with brushed dark matte plastic bottom bezel and brushed silver-coloured stand. The top and side bezels are dual-stage, with slim panel border flush with the rest of the screen and a slender hard plastic outer part. The OSD (On Screen Display) is controlled by a joystick which faces down beneath the central LG logo.
A 27″ IPS-type panel is employed with 3840 x 2160 (‘4K’ UHD) resolution and 60Hz refresh rate. Adaptive-Sync is supported, including AMD FreeSync with a 40 – 60Hz VRR range. A matte anti-glare screen surface is included, with a 1200:1 static contrast ratio and 178°/178° viewing angles specified. 10-bit colour is supported (8-bit + FRC assumed), whilst hardware calibration is supported with a compatible calibrator and LG Calibration Studio (True Color Pro) software. A flicker-free (‘Flicker Safe’) WLED backlight is used, offering a typical maximum luminance of 400 cd/m² and 95% DCI-P3 colour gamut. This is a notable change from the predecessors to this model which offered ~sRGB gamut coverage. A ‘Reader Mode’ Low Blue Light (LBL) setting is included to aid relaxing viewing. The monitor supports VESA DisplayHDR 400, allowing it to put its 10-bit colour processing and colour gamut to good use. But this does not necessitate a particularly high luminance level or local dimming. A 5ms grey to grey response time is specified, which as usual should be taken with a pinch of salt. DAS (Dynamic Action Sync) is included to automatically minimise input lag. The rear is white plastic, with the included stand attaching centrally via a quick-release mechanism. It offers tilt, height and pivot adjustment. 100 x 100mm VESA holes are included for alternative mounting. The ports face backwards in a recessed area to the right of the stand attachment point and include; USC-C (96W PD, DP Alt Mode, upstream data), DP 1.4, 2 HDMI 2.0 ports, 2 USB 3.0 ports, a 3.5mm headphone jack and DC power input (external ‘power brick’). 2 x 5W Maxx Audio speakers are also included for potentially quite rich sound output.
Further information can be found on the manufacturer’s website. The monitor is listed with an RRP of ~$550. As usual there are some cut-down variants such as the 27UP650 (27UP650-W) which lacks USB connectivity or integrated speakers and the 27UP600 (27UP600-W) with a tilt-only stand, no USB connectivity or integrated speakers.
