The ~32″ screen size is something of a sweet spot for the ‘4K’ UHD resolution. The Acer XB323QK NV (XB323QK NVbmiiphuzx), of the Predator series, offers this combination and tacks on that all-important high refresh rate as well. The monitor is instantly recognisable as a member of the series, with sharp lines and a powder-coated metal tripod-style stand. The top and side bezels are ‘dual-stage’, with a slim panel border that blends in seamlessly with the rest of the monitor when it’s switched off. And a slender hard plastic outer component. The bottom bezel includes a sensor unit towards the right 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 (‘ColourSense’) 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.

The usual sharp design

The monitor uses a 31.5″ IPS-type (In-Plane Switching or similar) panel with 3840 x 2160 ‘4K’ UHD resolution and 144Hz refresh rate. Most likely the Innolux M315DCA-K7B AAS (Azimuthal Anchoring Switch) IPS-type panel. This has a 1000:1 static contrast ratio specified, 178° horizontal and vertical viewing angles and 10-bit colour support (8-bit + FRC dithering). Adaptive-Sync is supported, including ‘G-SYNC Compatible Mode’, with an assumed 48 – 144Hz (plus LFC) variable refresh rate range. A matte anti-glare screen surface is employed, likely with a light finish, for good glare-handling without heavy diffusion of the image. A flicker-free WLED backlight is employed with 400 cd/m² typical maximum luminance and 90% DCI-P3 colour space coverage. As a model certified as ‘Eyesafe’ by TÜV Rheinland, it also has its blue light peak shifted to less energetic wavelengths for enhanced viewing comfort. The monitor will respond to HDR10 content via VESA DisplayHDR 400 support. This is the lowest level of HDR support they certify for and doesn’t necessitate local dimming or a particularly high luminance, but it will still allow 10-bit colour processing and the 90% DCI-P3 colour gamut to be used appropriately. A 1ms grey to grey response time is specified, but you shouldn’t pay too much attention to such figures anyway. The included stand offers full ergonomic flexibility, 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 include; DP 1.4, 2 HDMI 2.1 ports, USB-C (65W PD + DP Alt Mode), 4 USB 3.0 ports and a 3.5mm audio output.
