There is an ever-growing range of models combining the IPS panel type with high refresh rates. There’s also a drive towards an increase in resolution above Full HD. The Acer XB273U GX combines a relatively high resolution, high refresh rate and IPS panel type. As a member of the Predator series, it offers the distinctive and familiar sharp-lined styling of the series. The stand base is powder-boated metal with a tripod design. The top and side bezels are dual-stage. Including a slender panel border that blends into the rest of the screen plus a slender hard plastic outer component. The product page and press images show customisable RGB LED lighting strips either side of the central Predator logo. According to feedback from those who own the monitor, this feature was not actually included. The OSD (On Screen Display) is controlled by pressable buttons and a joystick at the rear of the monitor, towards the bottom right as viewed from in front.

Predator styling

The monitor features a 27″ 2560 x 1440 (WQHD) IPS-type panel; the AU Optronics M270DAN08.0 AHVA (Advanced Hyper-Viewing Angle) panel more specifically. This has a matte anti-glare screen surface, 1000:1 static contrast and 178° horizontal and vertical viewing angles. A 270Hz refresh rate is supported alongside Adaptive-Sync. This includes Nvidia’s ‘G-SYNC Compatible Mode’ and AMD FreeSync, with a 48 – 270Hz variable refresh rate range (plus LFC) assumed. 10-bit colour (8-bit + FRC) is supported and the monitor is factory calibrated with an average DeltaE <2 promised. A flicker-free Quantum Dot LED (Quantum Dots + blue LED) backlight is used, with generous ~99% Adobe RGB coverage for strong vibrancy and saturation potential plus a 400 cd/m² typical maximum luminance. Acer 'Bluelight Shield' Low Blue Light (LBL) settings are included for more relaxing viewing. The monitor supports VESA DisplayHDR 400, the lowest level that VESA certifies for. This allows the monitor to respond to HDR10 content, putting its colour gamut to good use and allowing the use of a 10-bit colour signal (with the help of GPU dithering). It does not necessitate a very high brightness levels or local dimming, so is far from a 'full fat' HDR experience. Although this model does include 16 dimming zones according to user reports, providing a situational boost to contrast.

The monitor has a specified 1ms or ‘up to 0.5ms’ grey to grey response time, which as usual you shouldn’t put too much weight on. The VRB (Visual Response Boost) strobe backlight setting is included as an alternative to Adaptive-Sync. The included stand offers tilt, height (100mm or 3.94 inches) and pivot adjustment (90° rotation into portrait). The screen can be quickly detached from the stand with a quick-release mechanism, revealing 100 x 100mm VESA holes. Most of the ports face downwards and include; AC power input (internal power converter), DP 1.4, HDMI 2.0, USB-C (DP Alt Mode plus 65W PD), 2 USB 3.0 ports and a 3.5mm headphone jack. 2 additional USB 3.0 ports are located on the left side of the monitor. 2 x 2W speakers are also included, for basic sound output.
