Built for the Modern Desktop

Beyond the impressive panel, AOC has packed the monitor with features for the modern professional gamer. The inclusion of DisplayPort 2.1 UHBR20 ensures enough bandwidth to handle the high resolution and frame rate requirements of the display. Additionally, the monitor includes built-in KVM functionality, picture-in-picture (PiP) and picture-by-picture (PbP) modes, and a retractable headphone hook. For aesthetic customization, it features integrated 'Light FX' music-synced ambient lighting.
