The Acer XB283K KV (XB283K KVbmiipruzx) of the Predator series offers this, with a ‘4K’ UHD resolution and 144Hz refresh rate supported. To allow games consoles to leverage this capability, HDMI 2.1 is offered for 120Hz ‘4K’ support on the Xbox Series X and PS5. The monitor has a coated metal stand base and uses matte plastics elsewhere – mainly black or dark grey with a touch of red where the stand base and neck connects. The bottom bezel houses the ‘VisionCare 3.0’ sensor suite, allowing the screen to adjust its brightness (‘LightSense’) and colour temperature (‘ColorSense’) according to ambient lighting. And allowing the screen to dim and ultimately turn off if nobody is using it (‘ProxiSense’). The OSD (On Screen Display) is controlled by buttons plus a joystick at the rear of the monitor. Running vertically down the right side, as viewed from in front.
A 28″ 3840 x 2160 (‘4K’ UHD) IPS-type panel is adopted, believed to be the Innolux M280DCA-E7B AAS (Azimuthal Anchoring Switch) panel. A 144Hz refresh rate is offered alongside Adaptive-Sync, including ‘G-SYNC Compatible Mode’ which this model is certified for with an assumed 48 – 144Hz VRR range plus LFC. HDMI 2.1 VRR is also supported. Other aspects of note include a light to very light matte anti-glare screen surface, 1000:1 static contrast and 178°/178° viewing angles. 10-bit colour support is also provided, via 8-bit + FRC dithering. A flicker-free WLED backlight delivers a 90% DCI-P3 colour gamut and 400 cd/m² peak luminance. An sRGB emulation setting with specified DeltaE <1 is also included. VESA DisplayHDR 400 support is included, a basic level which is quite limited in terms of luminance by HDR standards and doesn't require local dimming. Though the panel used does include 8 dimming zones for a slight situational edge in contrast. It also allows the monitor to put its 10-bit colour reproduction and reasonably generous colour gamut to good use.
The monitor is Eyesafe certified, meaning the backlight has a shifted (less energetic) blue peak for potentially enhanced viewing comfort. Traditional Low Blue Light (LBL) settings are included for relaxing evening viewing, too. A 1ms grey to grey response time (approach with caution) is specified. The included stand attaches using a quick release mechanism and can be replaced by an alternative 100 x 100mm VESA compatible solution if preferred. A flip-down headphone hook is included at the top of the stand neck and a cable-tidy loop further down. The stand is fully adjustable, including 115mm (4.53 inches) height adjustment and pivot into portrait. The ports mainly face downwards and include; DC power input (external ‘power brick’), DP 1.4 (with DSC), 2 HDMI 2.1 ports, USB-C (65W PD, DP Alt Mode, upstream data), 2 USB 3.0 ports and a 3.5mm audio output. 2 additional USB 3.0 ports are found at the left side of the screen, as viewed from the front. 2 x 2W speakers are also included, with the monitor also offering KVM functionality. This allows USB peripherals to be shared between multiple systems.
This model is the Predator-flavoured version of the Nitro XV282K KV we’ve reviewed. It appears to be very similar aside from going for ‘G-SYNC Compatible’ rather than FreeSync certification. This is just marketing and we’d expect actual VRR experience with either vendor to be unaffected by this – though FreeSync via HDMI support may be lacking on the Predator. HDMI 2.1 VRR is offered, however. The aesthetics are also different and we’re not sure if the Predator version offers KVM support. The monitor is listed for ~$630 USD.
