If you are trying to upgrade your gaming experience, the Acer predator XB321HK is the best gaming monitor to go with due to its fast performance and vivid display. The 32” inch monitor uses an IPS display to bring the most accurate colors to your screen. It has a quick response rate that gets rid of problems like ghosting, so you can enjoy gaming more. Speaking of enjoyment, the best computer monitors around can make your work and life a lot more pleasant.

Why We Like It – Acer Predator XB321HK

The Acer predator XB321HK is built to give you a better chance at winning games online. It uses Nvidia g sync to provide the smoothest graphics possible. It has two pre-installed speakers so you don’t have to worry about setting up a sound system if you don’t have space for it.

  • 144hz refresh rate will be good for FPS and other genres
  • IPS display shows the best viewing angles
  • Customers not impressed with the durability


Just like some of the leading 4K gaming monitors, the Acer monitor has a maximum resolution of 3840×2160, which is much higher than the average competition. While you embark on any competitive games, expect a smooth gaming performance since the response time on this monitor is at a solid 1ms so there is no ghosting happening during the game. It features Nvidia G Sync compatibility, so your monitor will link the refresh rate with the graphics card to provide a better experience. The end result is graphics with no motion blur, giving you a better experience that may grant you that competitive edge. If you would like g sync technology on your next monitor, another model to look at may be the Asus TUF VG27AQ. It includes two internal speakers that improve its portability when you don’t have enough space on your desk for a sound system.

Viewing angle

Since it uses an IPS panel type of screen, expect some of the best viewing angles available as well as bright colors to pair with it. It uses a widescreen display. There is also a feature known as Predator Gameview where you can choose different gaming profiles and change the setting to match the game you are playing. If you would like to find something smaller than the 32” inch display, you may want to take a look at the ViewSonic XG2402.


Customer reviews revealed that you may run into some issues with the monitor after a couple of years of use. While these issues may be rare or common, it is best to have some sort of insurance plan in the event of these problems. If you’ve been frightened away and would rather take a chance on another monitor, another possible suggestion is Alienware AW3418DW.

Equipped on this Acer monitor is a USB hub with 4 ports available for all your USB needs. This is a great addition because there are so many devices that can use this feature. It has a single HDMI port, so if you have extra consoles there may be a good chance that you’ll have to constantly change the cables to whichever console you are using. It also has a single DisplayPort.


For what it is worth, this monitor is what you want to buy once you have established yourself as a pro gamer and have the money to blow. In no way is this an option to go with if you are barely dipping your toe in the waters of e-sport competition since this monitor is about the price of a used car. Nevertheless, if you do have the funds feel free to splurge and indulge in the 4K greatness ingrained into this monitor.

Acer Predator XB321HK Wrap Up

The Acer predator XB321HK is an elite choice to go with if you are set on making a gaming setup that will last a very long time. While there are some reviews that make us question the durability, there are still plenty of customers that have enjoyed this monitor and used its abilities to become better gamers.
