Acer Predator XB321HK UHD 4K Monitor Design

The Acer's Predator line is famous for its daring designs and the Predator XB321HK is no exception, but it is hard to imagine this 4K monitor in an office setting since its design fits better in a more casual atmosphere.

 Acer Predator XB321HK UHD 4K Monitor Design

    1.       Design style

    With the XB321HK, Acer decided to stick with the recognizable look they used on the previous XB271HK Predator series model. The two monitors share the same red, silver and black color pattern, but the XB321HK has a larger display. The 32-inch IPS panel type can support image resolutions as high as 3840X2160 pixels, while it also offers a number of lower resolutions to users who don't need 4K image quality. With the size of 29.1 in x 12.2 in x 19 inches and the weight of 23.46lbs, with the stand, it is safe to say that the Acer's flagship monitor will take a lot of space on your desk.

    The 16:9 aspect ratio IPS panel enframed by remarkably thin bezels is supported by a futuristic looking stand that allows the bulky cabinet to be elevated as much as 5 inches. The V-shaped stand enables the Acer's 4K UHD 4K monitor to have a 30-degree tilt range. The Vesa mounting holes provide the possibility to disconnect the XB321K from the stand and mount it on a wall.

      2.       Ports and Connectivity

      Even though this Predator series model has all the ports it needs to provide a near perfect gaming experience, the connectivity is one area where the manufacturer could improve their flagship model. The XB31HK has only two video input ports, HDMI and DisplayPort, which can be a huge disadvantage for users that demand superb video playback features. In addition to two video input ports, this UHD 4K monitor has four USB 3.0 hubs and a 3.5mm headphone output.

      The Acer Predator XB321HK has overall great connectivity features, despite the fact that video input features are somewhat limited.

        3.       Display

        The IPS panel with a 16:9 aspect ratio and a native 4K resolution guarantee that the XB321HK can deliver high-end performances even while performing the most demanding tasks. The non-reflective anti-glare coating makes sure that the Acer's Predator series model is unfazed by the light conditions of the room. Furthermore, this 4K UHD monitor has a maximum brightness value of 350cd/m2 that gives the images displayed on this monitor incredible vibrancy that makes explosions or daylight scenes almost lifelike.

        The monitor's contrast value is at 100000000:1, which further expands its already impressive color management, although users might experience some light bleed issues, especially with dark scenes. The backlight uses a white LED constant current that reduces the flickering and lessens the amount of the backlight bleed. The widescreen 4K UHD monitor has a 178 degree horizontal and vertical viewing angles that guarantee the picture quality doesn't deteriorate when the images that are displayed on the monitor's screen are viewed at an angle. The XB321HK's 4K IPS panel is without question equipped with all the right tools to deliver the best viewing experience to its users, although the high-end professional users might find some of its features slightly underwhelming.

        Acer Predator XB321HK UHD 4K Monitor Color Performance

        The richness of colors on the XB321HK will impress even the biggest skeptics because this remarkable gaming 4k monitor has a native 10-bit color depth accompanied by a 100% sRGB color gamut. With a 1.07 billion screen color depth, the monitor's primary colors are adjusted to the Commission on Illuminations standard, which enables the XB321HK to display vivid and lifelike colors. Like the Acer's previous models in the Predator series, this monitor can display 100% of the sRGB color gamut. The Acer's 4K UHD monitor has an equally impressive RGB performance that places it among the best 4K monitors on the market today.

        Red, Green and Blue colors displayed on the XB321HK are nearly perfect and when combined with the UHD image quality the final result is the picture quality that depicts even the smallest details with stunning clarity in vivid colors.

        Acer Predator XB321HK UHD 4K Monitor OSD Settings and Calibrations

        The monitor's menu is easy to use and it enables you to calibrate the monitor manually. The XB321HK uses the traditional Acer's bezel-based keys that give you instant access to the menu. The eColor management feature allows you to choose preset values while changing any color value by yourself will enable you to switch to the User mode that allows you to calibrate the monitor manually.

        Perhaps one of the more useful features is the Blue Light setting that reduces the blue primary in order to make the white points warmer and in turn lessen the eye fatigue caused by the prolonged usage of this monitor. Furthermore, users can manually adjust Red, Green and Blue levels by choosing the 6-Axis color option, a feature that enables the users to calibrate the monitor so that it perfectly fits their demands. Picture settings such as Movie, Standard or Eco modes allow the user to easily choose the properties that best fit their current needs.

        Acer Predator XB321HK UHD 4K Monitor G-Sync Performance

        Nvidia's G-Sync technology reduces the screen tearing by forcing the video display to adapt to the video output device. The Acer's Predator XB321HK is equipped with G-Sync technology that enables it to have the refresh rate as low as 60 Hz and still keep screen tearing at an amazingly low level.

        This feature alone makes the XB321HK one of the kind gaming monitors that have absolutely no problem running 4K games at the same speed as the computer's graphic card allows. The gamers have no reason to worry about the stutters and since the G-Sync technology makes sure that the frame rates of the computer and the XB321HK monitor are exactly the same.

        Acer Predator XB321HK UHD 4K Monitor Gaming Performance

        The Acer's 32-inch 4K UHD monitor is designed to maximize the gameplay experience and display vivid and crystal clear images that captivate the attention. With a response time as short as 4 milliseconds, the XB321HK has almost no discrepancy between the time the user issued a command and the time when the command is displayed on the monitor. This is particularly important for gamers who like playing action or racing games that demand fast reactions from the players.

        In addition, the Acer's Predator series monitor provides a screen that is large enough to display true 4K images which further enhances the gaming experience since the gameplay of even the most graphically demanding games run smoothly on this 4K monitor. Despite its high price gamers who only want the best gaming experiences cannot go wrong by purchasing this 4K UHD monitor.

        Acer Predator XB321HK UHD 4K Monitor Audio Performance

        To make things even better the Taiwanese manufacturer has equipped their XB321HK model with a pair of 2-watt speakers that provide more than decent audio output. The sound produced by the monitor's speakers might have too much treble and like most built-in speakers it lacks bass, but users can utilize the Predator XB321HK's speaker without the aid of the external sound system and still get more than decent audio playback.

        The monitor also has a 3.5mm headphone output that enables you to use the monitor with gaming consoles that don't have their own sound system Be it as it may, most video games or any other 4K visual content is best consumed with a stereo sound system that enriches the gaming experience.


        At the market price of $1276, the Acer XB321HK may seem too expensive for a gaming 4K monitor. However, a wide color gamut, low latency, and UHD image quality all suggest otherwise. The Nvidia's G-Sync anti-tearing technology further raises the capacity of this 4K monitor and places it at the top of its class. A unique set of features accompanied by a 16:9 aspect ratio, widescreen IPS display add to the XB321HK's value and vouch that Acer's Predator series 4K monitor will deliver high standard performances even when pushed to its limits.

        The users who need a 4K monitor to meet their every gaming desire will certainly benefit from buying this monitor, while most other users, including the very demanding professional photographers and videographers, would most certainly be pleased with the capabilities of the Acer's unique 4K monitor.
