OLED technology is something we’ve been writing about for several years, but adoption of this for monitors has been painfully slow. The LG 32EP950 (32EP950-B owing to black rear) of the UltraFine OLED Pro series is a colour-focused OLED offering. The styling is simple and modern, with fairly slender bezels – matte dark grey plastic covering the panel border. So a single-stage rather than dual-stage design. The screen is relatively slender owing to the fact a backlight is not required. The stand base is crescent-shaped with a brushed powder-coated metal finish, with a thick tubular neck. The OSD (On Screen Display) is controlled by a joystick which faces downwards beneath the central LG logo.
A 31.5″ OLED panel from JOLED is used with 3840 x 2160 (‘4K’ UHD) resolution and 60Hz refresh rate. A very light matte (‘semi glossy’) screen surface is used, whilst a 1M:1 static contrast ratio – dwarfing the contrast ratio of LCD offerings. 178°/178° viewing angles are specified, whilst true 10-bit colour is supported. The monitor is factory calibrated, with hardware calibration supported using a compatible calibration device and LG Calibration Studio (True Color Pro) software. The monitor covers 99% DCI-P3 and 99% Adobe RGB and has a brightness of 250 cd/m² ‘minimum’ specified. Due to potential burn-in issues, it’s usual for such models to have luminance that’s more limited than their LCD counterparts and may limit this with a lot of bright content displayed. The monitor responds to HDR10 content by way of VESA DisplayHDR 400 True Black – focusing more on putting the generous colour gamut and 10-bit support to good use than sustained high brightness. A peak luminance of 400 cd/m² can be achieved, with per-pixel illumination for exceptional contrast. A 1ms grey to grey response time is specified, which is realistically achievable without the sort of aggressive pixel overdrive required for LCDs. Dynamic Action Sync (DAS) is also integrated into the monitor to minimise input lag. The included stand attaches centrally using a quick-release mechanism and can be removed to reveal 100 x 100mm VESA holes for alternative mounting. The included stand affords tilt, height and pivot adjustment. The ports are located to the right of this, facing backwards, and include; USB-C (90W PD, DP Alt Mode and upstream data), 2 DP 1.4 ports, HDMI 2.0, 3 USB 3.0 ports (plus upstream), a 3.5mm headphone jack and DC power input (external ‘power brick’).
Further details can be found on the manufacturer’s website. The monitor is listed for ~$4000 USD.
