Struggling with blurry frames and lag during intense matches? You need a monitor that can keep up with every split-second decision. The Acer Predator XB323QKV4 delivers crystal-clear visuals and ultra-fast response so you never miss a beat.
Acer Predator XB323QKV4 31.5" 4K 3840x2160 320Hz 0.5ms Gaming Monitor
This 31.5-inch IPS panel brings 4K Ultra HD resolution to your desk, offering four times the detail of a standard Full HD screen. HDR10 adds deeper blacks and brighter highlights, creating a lifelike gaming world. A blistering 320 Hz refresh rate combined with a 0.5 ms gray-to-gray response time eliminates motion blur, while AMD FreeSync Premium synchronises the monitor’s refresh with your graphics card for tear-free gameplay. The ergonomic stand lets you tilt, swivel, pivot, and raise the screen up to 15 cm, so you can find the perfect viewing angle for marathon sessions.
Beyond raw speed, the monitor covers 95 % of the DCI-P3 colour gamut, delivering vivid and accurate colours that make every environment pop. The 178° viewing angles ensure consistent image quality from any side of the desk. With a peak brightness of 250 cd/m² and a dynamic contrast ratio of 100 000 000 :1, dark scenes reveal hidden details while bright areas stay punchy. Built-in speakers provide basic audio, and the dual HDMI 2.1 and DisplayPort 1.4 ports give you flexible connectivity for the latest consoles and graphics cards.
Energy efficiency is also considered - the monitor draws only 33 W typical power and includes flicker-free and low-blue-light technologies to reduce eye strain during long play sessions. A Kensington lock slot and VESA-compatible mounting options let you secure the display in competitive environments or mount it on a wall for a clean setup. With a two-year warranty, Acer backs the durability of this high-performance gaming tool.
