The visually impressive U2879VF combines an expansive 28” screen size with 4K Ultra HD resolution for super-sharp, highly detailed images. The 10-bit Deep Color panel can display over a billion hues simultaneously, for superb realism and natural shading. A blisteringly fast screen response time of just 1ms shows fast-moving action without blurring, while AMD FreeSync™ Technology matches the graphics signal to the screen timing to eliminate stuttering and tearing.

Ultra high definition 3840 x 2160 resolution (4K UHD) yields a superior pixel density of 157 PPI (pixels per inch) on the large 28-inch screen, for outstandingly detailed images.

The 10-bit Deep Color RGB display panel ensures substantially more natural transitions between hues for exceptional realism.

AMD FreeSync technology synchronizes the GPU and the monitor so frames are displayed when ready: no tearing or stuttering.

  • High performance solution with all the benefits of variable refresh rate technology.
  • Based on industry standards, not expensive proprietary solutions.
  • Cheaper and easier to implement: no additional monitor hardware, no license fees.
  • Cheaper for consumers.
  • Support multiple use cases: Gaming, Video, Power Saving.

Fast 1ms (GTG) screen response displays moving images without blurring.

With AOC Shadow Control gamers can dial-in shadow levels in the OSD Menu to increase contrast for better dark areas on the screen definition without affecting the rest of the screen.

With multiple inputs like DisplayPort, HDMI and Dual-Link DVI, this monitor enables you to multiply your viewing with Picture-in-Picture and Picture-by-Picture capabilities, e.g. watch a video from a media device with HDMI connection on one part of the screen, while browsing the Internet from a computer with DisplayPort connection on the rest of the screen.

HDMI (High-Definition Multimedia Interface) is the digital video and sound standard for connecting the latest consumer electronics like Blu-ray players and game consoles. DisplayPort is designed to be the future digital video and sound connection standard, capable of higher performance and convenience than older formats.

To save power, a timer can be set to automatically turn off the monitor after a user-defined interval.

Software enables the user to set a low power configuration of the monitor when the PC is in screen saving, PC off, and user absence. User can choose the time to turn the monitor off, to save power consumption.

The bundled Screen+ software splits the PC workspace into four self-contained panes to group application windows for easier viewing. Screen+ also supports multiple monitors.

Included PC software allows the user to change the OSD settings using their mouse.
