The ‘4K’ UHD resolution brings several benefits. Combining this with a decent HDR experience and high refresh rate can really hit the sweet spot for some users. That’s exactly what the Acer XB273K GS achieves for both PC and modern games console users. With HDMI 2.1 allowing it to run ‘4K’ UHD @120Hz on compatible games consoles such as the PS5 and Xbox Series X. It shares the styling elements of some others in the Predator series, including a wide-footed coated metal stand base and a red stripe where the base and stand neck joins. The bottom bezel is moderately thick, with a dark grey matte plastic finish. The top and side bezels are dual-stage, with a slender panel border flush with the rest of the screen. And a slim hard plastic outer part. The OSD (On Screen Display) is controlled by a joystick and buttons running down the rear of the monitor, towards the right side as viewed from in front.
A 27″ 3840 x 2160 (‘4K’ UHD) IPS-type panel is used, more specifically an AU Optronics AHVA (Advanced Hyper-Viewing Angle) panel. This supports a 160Hz refresh rate, alongside Adaptive-Sync – including Nvidia’s ‘G-SYNC Compatible’ VRR technology, with a 48 – 160Hz VRR range plus LFC assumed. Other aspects to note include a 1200:1 static contrast, 10-bit colour support (8-bit + FRC likely), 178°/178° viewing angles and an expected light to very light matte anti-glare screen surface. The monitor includes a factory calibrated sRGB emulation setting with a specified DeltaE <1. The flicker-free Quantum Dot LED backlight solution provides a 450 cd/m² typical maximum luminance (650 cd/m² HDR peak) and 99% Adobe RGB colour space coverage. VESA DisplayHDR 600 support is included, with a degree of local dimming allowing a situational boost to contrast. And allowing the reasonably high luminance levels, 10-bit colour processing and generous colour gamut to do their thing for HDR10 content.
Low Blue Light (LBL) settings are included to promote a more relaxing viewing experience. As usual you shouldn’t pay too much attention to specified response times, but in this case a 1ms or ‘up to 0.5ms’ grey to grey response time is specified. The manufacturer includes their fully adjustable ‘ErgoStand’, which includes the usual tilt alongside swivel, height adjustment and pivot into portrait. The ports mainly face downwards and include; AC power (internal power converter), 2 HDMI 2.1 ports, 2 DP 1.4 (with DSC), USB-C (65W PD, DP Alt Mode, upstream data), a 3.5mm audio output and 2 USB 3.0 ports. 2 additional USB 3.0 ports are located at the left side of the monitor, as viewed from the front. 2 x 4W speakers are also included for basic audio output.
