Stunning 4K Ultra HD Resolution on the Desktop

This 4K2K Ultra HD display provides the highest resolution available in a desktop monitor. Featuring a 3840 x 2160 pixel screen that contains more than 8 million pixels, this ViewSonic display has four times more pixels than Full HD resolution displays. In addition, the large 28 display can simultaneously display two inputs on the screen, maximizing productivity while delivering the ultimate in image detail and clarity.

10-bit colour processing for an amazing 1.07 billion colours

With innovative 10-bit colour processing, this display can generate up to 1.07 billion colours for smooth colour-to-colour transitions, as well as enhanced grayscale performance. By displaying up to 1.07 billion colours, the VX2880ml delivers professional-grade colour accuracy and stunning images ideal for any multimedia application.

High-Definition Daisy Chain Capability

Equipped with 2 DisplayPort inputs and 1 DisplayPort output, the VX2880ml supports daisy-chaining of multiple displays for multi-screen setup and easy cable management. Even with multiple displays daisy-chained to the VX2880ml, high-definition content and colour remains consistent across screens. Quad HD is supported on two daisy-chained displays (two screens total), while Full HD is supported on four daisy-chained displays (four screens total).

MHL functionality for easy connection to mobile devices

Integrated with Mobile High-Definition Link (MHL), the VX2880ml enables users to connect compatible mobile devices, such as smartphones and tablets, directly to the VX2880ml. This allows digital content from mobile devices to be viewed in stunning Full HD resolution on the larger screen of the VX2880ml, while also simultaneously charging the batteries of the mobile device.

Planet-Friendly Mercury-Free LED Backlighting

LED backlighting enhances display performance, delivers an outstanding colour range, and adjusts contrast ratios for remarkably detailed images. ViewSonic's eco-friendly, mercury-free LED backlighting further conserves up to 25%* more energy when compared to conventional displays. In addition, LED backlighting provides for a slim, lightweight profile that saves desktop space.

Eco-mode Conserves More Energy

ViewSonics proprietary Eco-mode feature is built into all LED displays, offering options to select ʺOptimize(75%)ʺ or ʺConserve (50%)ʺ settings that save up to 25% power. Especially in low ambient light, Eco-mode adjusts brightness and improves visibility, while reducing eye fatigue and prolonging the display's lamp life. With Eco-mode, both lamp replacement and energy expenditures are reduced.

Dual Integrated Stereo Speakers

The ViewSonic VX2880ml has two integrated 2W stereo speakers for enhanced multimedia performance with crystal-clear stereo sound.

ViewSonic Flicker-Free viewing for improved eye comfort

ViewSonic flicker-free displays deliver on the promise of more comfortable viewing. Instead of using Pulse Width Modulation that continuously turns the LED backlight on and off, ViewSonic flicker-free displays use DC modulation backlights that maintain a steady stream of direct current powernearly eliminating screen flickering at all brightness levels by providing a constant LED light source. This lets you work at your computer, play games, or watch movies longer without eye fatigue.

Blue light filter for more comfortable viewing

Prolonged exposure to certain levels of blue light can cause eye discomfort. ViewSonic displays feature a Blue Light Filter setting that allows users to adjust the amount of blue light emitted from the screen, enabling longer viewing times and increased eye comfort for work and multimedia applications.

VESA-Mountable

The ViewSonic VX2880ml features a 100 x 100mm VESA-mountable design that allows the display to mount on a monitor stand on a wall, depending on specific needs.
