The ‘4K’ UHD resolution combined with a 27″ screen delivers an excellent pixel density. Providing strong detail and clarity to text, games and other suitably high resolution content. The LG 27GP950 (27GP950-B due to black rear) combines this with a 160Hz refresh rate and a range of attractive gaming-oriented features. This member of the UltraGear series includes slender bezels on all sides, with a dual-stage design that includes a slim panel border flush with the rest of the screen. And a slim hard plastic outer component. The Y-shaped stand base includes red elements to contrast with the matte black plastic used elsewhere. The OSD (On Screen Display) is controlled by a central down-facing joystick.

A sleek design

A 27″ 3840 x 2160 (‘4K’ UHD) LG Display Nano IPS panel is employed, with very light matte anti-glare screen surface and 10-bit (8-bit + FRC) colour support. A 160Hz refresh rate is supported by way of 144Hz with internal factory overclock. Adaptive-Sync is also supported, including AMD FreeSync Premium Pro and Nvidia’s ‘G-SYNC Compatible Mode’ which this model is officially certified for. A 48 – 160Hz VRR range is supported, alongside LFC. A 1000:1 static contrast ratio is specified alongside 178° horizontal and vertical viewing angles. Hardware calibration is supported using True Color Pro software and a compatible calibration device. A flicker-free WLED backlight delivers a 98% DCI-P3 colour gamut and 400 cd/m² typical maximum luminance. This can boost to 600 cd/m²+ for HDR10 content, with the monitor VESA DisplayHDR 600 certified. This allows it to make use of relatively high brightness, whilst putting the 10-bit colour support and fairly generous colour gamut to good use. 16-zone edge-lit local dimming is also provided for a situational edge in contrast. A 1ms grey to grey response time is specified, which as usual you shouldn’t put too much weight on. The monitor also includes an integrated low input lag feature; Dynamic Action Sync (DAS).

The rear is mainly matte black plastic, with some intertwining red elements. A ring of RGB LEDs surrounds the central region; ‘Sphere Lighting 2.0’. This can be controlled using a dedicated scroll wheel beside the OSD control joystick or using UltraGear Control Center software. The lighting is powerful enough to create an aura of light around the monitor, on the wall behind, so can be used as a bias light to enhance perceived contrast. It also includes a ‘Sound Sync’ setting allowing it to react to sound passed through the monitor. And ‘Video Sync’ which allows it to respond to on screen content. The included stand offers tilt, height and pivot adjustment and attaches using a quick-release mechanism. Removing it reveals 100 x 100mm VESA holes for alternative mounting. The ports face backwards to the right of the stand attachment point and include; 2 HDMI 2.1 ports, DP 1.4 (with DSC), 2 USB 3.0 ports (plus upstream), a 3.5mm headphone jack and DC power input (external ‘power brick’). DSC functionality supports the full feature set of the monitor simultaneously, including ‘4K’ UHD @160Hz VRR with 10-bit colour and HDR. The HDMI 2.1 port is a key addition to this model which was not found on its predecessor, the 27GN950. It allows the screen to run at ‘4K’ UHD @120Hz with VRR and HDR, making it attractive for modern games consoles such as the PS5 and Xbox Series X.

An RGB LED feature that's actually useful

Further information can be found on the manufacturer’s website. The monitor is listed for ~£750 with availability expected in various regions by June 2021.
