For many, the combination of 2560 x 1440 resolution, 144Hz+ refresh rate and IPS-type panel is extremely desirable. The Acer XB273U GS (XB273UGS or XB273UGSbmiiprzx), of the Predator series, offers this attractive combination. It has the usual ‘sharp-lined’ style that the series is known for, along with a solid powder-coated metal ‘footing’ to the stand. The bottom bezel attracts a little more visual interest than usual, with two long RGB LED lighting strips and a matte silver plastic material surrounding them. These can be customised in the OSD to show a static or breathing red, green or blue. Or a rainbow effect if you’re feeling adventurous. Alternatively they can be set to react to sound being fed to the monitor (‘LightSense’) or disabled so they just blend in nicely. The top and side bezels are ‘dual stage’ or ‘ZeroFrame’ as Acer refers to them. Including a slim panel border that’s flush with the rest of the screen and a slender hard plastic out component. The OSD (On Screen Display) is controlled by pressable buttons and a joystick at the rear of the monitor, running down the right side as viewed from the front.

Illumination for the bottom bezel

A 27″ IPS-type (In-Plane Switching technology) panel is used, most likely an AUO AHVA (Advanced Hyper-Viewing Angle) part. This includes a 2560 x 1440 (WQHD) resolution, light matte anti-glare screen surface, 178° horizontal and vertical viewing angles. A 1000:1 static contrast is specified, with true 8-bit colour supported. A refresh rate of 165Hz is supported alongside Adaptive-Sync, including support for AMD FreeSync and Nvidia’s ‘G-SYNC Compatible Mode’. A 48 – 165Hz variable refresh rate range with LFC (Low Framerate Compensation) is assumed. A flicker-free WLED backlight is employed offering a 400 cd/m² typical maximum luminance and 95% DCI-P3 colour space coverage. The monitor is VESA DisplayHDR 400 certified, giving basic HDR support. A 10-bit colour signal can be used with the help of GPU dithering and the colour gamut put to good use for HDR10 content, but this is only a basic HDR experience and doesn’t require local dimming or a particularly high luminance by HDR standards. A 1ms grey to grey response time is specified, but as usual don’t put too much weight on that. The included stand attaches using a quick-release mechanism and includes tilt and height (11.50cm or 4.53″) adjustment. It can be removed to make way for an alternative 100 x 100mm VESA compatible solution. The ports mainly face downwards and include; DP 1.4, 2 HDMI 2.0 ports, a 3.5mm headphone jack and AC power input (internal power converter). 2 USB 3.0 ports are located at the left side of the monitor, with the upstream port included with the downwards-facing rear ports. 2 x 2W speakers are included for basic sound output.
