Gamers’ choice
XB1 series monitors are packed full of features to choose from. Create your own ultimate gaming experience with extreme resolutions, fast refresh rates, IPS[1] technology and more[2]. Standard features like GameView and NVIDIA® G-SYNC™ make every choice a good one.
Pixel power
Gaming monitors used to sacrifice colour for speed, but now there’s no need to compromise with a range of gorgeous and powerful displays. IPS[1] technology provides rich colour and you can even overclock to 165Hz[2] of gaming glory. Once you try it, you won’t go back.
NVIDIA® G-SYNC™
Get the smoothest gaming experience on the planet with NVIDIA® G-SYNC™. G-SYNC™ eliminates screen tearing and minimises stuttering by syncing the refresh rate of your monitor with the frames rendered by your GPU. This is legendary PC gaming.
Seize control
Take charge of any situation with Predator GameView. Adjust dark boost levels, make precise colour adjustments and set up aim points for hip-fire accuracy. Save custom settings in three profiles you can switch between at any time.
NVIDIA® ULMB
Tired of that ugly motion blur when you drift around corners? Get a superb racing experience with NVIDIA® ULMB[2] (Ultra Low Motion Blur) technology for crystal clear gameplay at high frame rates.
All the colours
Good colour brings game worlds to life and lets you pick out enemies with precision. We managed to get the XB1 series up to 100% sRGB[2]. Now that’s some accurate colour!
Get comfortable
Predator EyeProtect’s Flicker-less, Blue-light Filter, ComfyView and Low-dimming technologies minimise eye-strain from long gaming sessions.
ZeroFrame
One for fun, two for multi-tasking, three for an ultimate gaming experience. Enjoy immersive multiple-monitor setups with ZeroFrame[2] bezels that keep you in the game.
