The ‘4K’ UHD resolution can be attractive for productivity tasks, video watching and gaming on both a PC and console. The Gigabyte M27U is built with this in mind, including HDMI 2.1 to offer a ‘4K’ UHD @120Hz experience for compatible devices including the PS5 and Xbox Series X. The monitor has the usual styling associated with the series, with a basic matte black plastic chassis. The top and side bezels are dual-stage with slim panel border flush with the rest of the screen plus thin hard plastic outer part. The OSD (On Screen Display) is controlled by a joystick at the rear of the screen, towards the right side as viewed from the front. A dedicated KVM button is found above this, allowing quick input switching and USB reassignment between 2 systems.

Plenty of matte black plastic

A 27″ 3840 x 2160 (‘4K’ UHD) IPS-type panel is used with matte anti-glare screen surface. A 1000:1 static contrast ratio, 178°/178° viewing angles and 10-bit colour is supported. A 160Hz refresh rate is offered alongside Adaptive-Sync (and HDMI 2.1 VRR assumed), allowing VRR technologies including AMD FreeSync Premium Pro and ‘G-SYNC Compatible’ to be used. The VRR range is specified as 48 – 160Hz (48 – 150Hz for HDMI). A flicker-free WLED backlight provides a 95% DCI-P3 colour gamut and 400 cd/m² typical maximum luminance. Low Blue Light (LBL) settings are included to provide a potentially more relaxing viewing experience. The monitor responds to HDR10 content at the VESA DisplayHDR 600 level, allowing it to put the fairly generous DCI-P3 coverage to good use alongside 10-bit colour processing. As well as some brightness bursts of 600 cd/m²+, with basic edge-lit local dimming providing a situational edge in contrast.

A 1ms MPRT response time is specified using ‘Aim Stabilizer Sync’, a strobe backlight setting which can be used in a VRR environment. The stand attaches centrally with a quick-release mechanism and can be replaced by an alternative 100 x 100mm VESA compatible solution if preferred. The stand offers tilt and height (130mm or 5.12 inches) adjustment. The ports face downwards and include; AC power input (internal power converter), 2 HDMI 2.1 ports, DP 1.4 (with DSC and HBR3), USB-C (18W PD, DP Alt Mode, upstream data), 3 USB 3.2 Gen 1 ports (plus Type-B upstream) and a 3.5mm headphone jack. 2 x 3W speakers are included and PbP/PiP support is included.

VESA mounting supported
