The combination of ~32″ screen and ‘4K’ UHD resolution provides an immersive and pixel-dense experience. The Acer XB323QK LV (XB323QK LVbmiiphuzx) of the Predator series provides this, coupled with a high refresh rate as a nod towards a fluid gaming experience. The monitor has the familiar sharp-lined ‘aggressive’ look often associated with the series, including a coated metal stand and dark matte plastic bottom bezel. The top and side bezels are dual-stage, with slim panel border flush with the rest of the screen and thin hard plastic outer part. The bottom bezel includes a sensor unit towards the left side, used for some of Acer’s ‘VisionCare 4.0’ functionality. This allows the screen to react to ambient lighting and adjust its brightness (‘LightSense’) and colour temperature (‘ColorSense’) based on this. A ‘ProxiSense’ proximity sensor also features, allowing the screen to dim or turn off if nobody is using it. The OSD (On Screen Display) is controlled by pressable buttons on the underside of the bottom bezel, towards the right side.

Aggressive styling

A 31.5″ IPS-type panel is used, with 3840 x 2160 (‘4K’ UHD) resolution and 144Hz refresh rate. Adaptive-Sync is supported, including AMD FreeSync Premium with 48 – 144Hz VRR range plus LFC. HDMI 2.1 support is included, providing a ‘4K’ UHD signal for systems including the PS5 and Xbox Series X alongside integrated VRR. Other aspects of note include a 1000:1 static contrast ratio, 178°/178° viewing angles and 10-bit colour support (8-bit + FRC dithering). A matte anti-glare screen surface is included, whilst a flicker-free WLED backlight provides a 90% DCI-P3 colour gamut and 400 cd/m² HDR peak luminance. The monitor is ‘Eyesafe’ certified by TÜV Rheinland, with its blue light peak shifted to less energetic wavelengths to potentially improve viewing comfort. The monitor includes a factory calibrated sRGB setting with DeltaE <1 specified. The screen responds to HDR10 content in a basic way, at the VESA DisplayHDR 400 level. This allows 10-bit colour processing to be used and the gamut to be put to good use, but is quite restricted in terms of brightness and colour gamut for HDR and doesn't require local dimming to enhance contrast.

A grey to grey response time of ‘up to 0.5ms’ is specified – pay little attention to this figure, as usual. The stand is fully adjustable, attaches with a quick-release mechanism and can be replaced by an alternative 100 x 100mm VESA compatible solution if preferred. A ring of ‘AdaptiveLight’ RGB LEDs are found at the rear, which can be set to various different colours or set to respond to audio or content on the screen. The ports mainly face downwards and include; DP 1.4 (with DSC), 2 HDMI 2.1 ports, USB-C (65W PD, DP Alt Mode, upstream data), 2 USB 3.0 ports plus Type-B upstream and a 3.5mm audio output. 2 further USB 3.0 ports are located at the left side of the screen. The monitor offers KVM functionality, allowing easy USB peripheral sharing and display input switching between 2 systems. 2 x 4W speakers are also included, facilitating basic sound output.
