The Acer Predator XB283K V3 (XB283K V3bmiiprx) offers this, with HDMI 2.1 included to provide a ‘4K’ UHD @120Hz experience for compatible devices including the PS5 and Xbox Series X. The screen includes a crescent-shaped dark silver coated metal stand, with top and side bezels adopting the popular dual-stage design. This includes a slender panel border flush with the rest of the screen plus thin hard plastic outer part. The OSD (On Screen Display) is controlled by a joystick and buttons at the rear of the screen, running down vertically towards the right side as viewed from the front.
A 28″ 3840 x 2160 (‘4K’ UHD) IPS-type panel is used, more specifically an Innolux AAS panel. A matte anti-glare screen surface is adopted and 1000:1 static contrast ratio plus 178°/178° viewing angles specified. A 150Hz refresh rate is supported alongside Adaptive-Sync (and HDMI 2.1 VRR assumed), allowing VRR technologies including AMD FreeSync Premium and Nvidia ‘G-SYNC Compatible’ to be used. A 48 – 150Hz VRR range plus LFC is assumed. A flicker-free WLED backlight provides a 90% DCI-P3 colour gamut and 400 cd/m² typical maximum luminance. The monitor is ‘Eyesafe’ certified (2.0 standard) by TÜV Rheinland, with the blue peak shifted to less energetic wavelengths and the amplitude of the peak reduced to potentially improve viewing comfort.
The monitor responds to HDR10 content in a basic way, at the DisplayHDR 400 level. It can leverage 10-bit colour processing and put its gamut to potentially good use – but no local dimming is required at this tier (though simple edge-lit dimming may be included) and brightness plus colour gamut is relatively limited. A 1ms grey to grey response time is specified – caution advised as usual. The stand attaches centrally with a quick-release mechanism and can be replaced by an alternative 100 x 100mm VESA compatible solution if preferred. The stand is fully adjustable, including height adjustment (4.72 inches or 120mm) and pivot into portrait. The ports face downwards and include; DP 1.4 (with DSC), 2 HDMI 2.1 ports and a 3.5mm headphone jack. 2 x 2W speakers are also included for basic sound reproduction.
Further details can be found on the manufacturer’s website. The monitor is listed for ~$500 USD.
