The tight pixel density offered by 27-28″ ‘4K’ UHD models brings a lot to the table for both work and play. With the latter in mind, having a high refresh rate to go with it can also be very attractive. The AOC U28G2X (U28G2XU European designation) of the G2 Series offers this attractive combination. The screen has a broad-legged stand base, with a matte black finish for the ‘XU’ and satin silver for the ‘X’. The bottom bezel is matte black plastic, whilst the top and side bezels offer a dual-stage design. With slender panel border flush with the rest of the screen, plus a slim hard plastic outer component. The OSD (On Screen Display) is controlled by buttons facing downwards on the bottom bezel, towards the right side as viewed from the front.

The front view

A 28″ 3840 x 2160 (‘4K’ UHD) IPS-type panel is adopted, believed to be from the Innolux M280DCA AAS (Azimuthal Anchoring Switch) family. A 144Hz refresh rate is supported alongside Adaptive-Sync, including a AMD FreeSync Premium Pro with a 48 – 144Hz VRR range (plus LFC). Other aspects of note include a light to very light matte screen surface, 1000:1 static contrast ratio and 178°/178° viewing angles. True 8-bit colour is supported, whilst a flicker-free WLED backlight offers a 370 cd/m² typical maximum luminance and 95% DCI-P3 colour gamut (98.8% DCI-P3 coverage according to some press material). VESA DisplayHDR 400 is supported, with the backlight pulsing up to a specified 460 cd/m² peak luminance for this. The generous colour gamut can also be put to work here, whilst a 10-bit signal is enabled with the help of GPU dithering. This is a low level of HDR10 support, though, and it doesn’t require a particularly high peak luminance by HDR standards or local dimming capability. Low Blue Light (LBL) settings are included to help create a more relaxing viewing experience.

A 1ms MPRT response time is specified using the MBR (Motion Blur Reduction) strobe backlight setting. The stand attaches using a quick-release mechanism and can detached to reveal 100 x 100mm VESA holes. It offers full adjustability, including 130mm (5.12 inches) height adjustment and pivot into portrait. The ports face downwards and include; 2 HDMI 2.0 ports, DP 1.4 (with DSC), a 3.5mm headphone jack and AC power input (internal power converter). The ‘XU’ variant includes 4 USB 3.2 Gen1 ports (plus upstream) and 2 x 3W speakers. Unlike competing models this one’s focused primarily on PC gaming rather than console gaming as it lacks HDMI 2.1 support. Although the monitor can run 2560 x 1440 @120Hz for the Xbox Series X/S.
