The ViewSonic VP2780-4K is a 27” Professional Ultra HD LED monitor that delivers stunning definition for color-critical applications. With 3840×2160 resolution, and SuperClear® AH-IPS technology for wide-angle viewing, this 10-bit monitor can display up to 1.07 billion colors with pre-calibrated Delta E≤2. This provides superior color accuracy and performance for content creation, graphic design, print, and other professional applications. Equipped with an exclusive wide-range gamma setting and ViewMode technology, the VP2780-4K delivers optimized screen adjustments for different viewing scenarios. This is also one of the first Ultra HD monitors to feature future-proof HDMI 2.0 to support 4K content at 60hz, along with DisplayPort 1.2a, dual MHL connectivity, and 4-port USB 3.0 for versatile connectivity to computing and entertainment devices. ViewSonic’s MultiPicture functionality allows for efficient multitasking by providing simultaneous viewing of up to four split windows, while full ergonomic functionality delivers maximum comfort and enhanced productivity.

Unique Color Calibration Factory Report

In order to meet professional graphic designers, video editors, and image processors’ high standard of color, ViewSonic utilizes specific color (SRGB,EBU,6500k) calibration procedures into the flow of production. Before delivering, each VP2780-4K monitor is manually examined by a professional color expert in order to confirm that its color, brightness and color temperature match with the sRGB, Native, and EBU (European Broadcasting Union) color gamut standards. In this unique and detailed Color Calibration Factory Report, three sets of color information and manufacturing results are recorded. Delta E is examined and tested to adjust the color difference and to make sure it can achieve Delta E ≤2, one of the highest color accuracy standards. The gamma curve is examined to measure and compare the brightness performance based on light and dark scenarios by observing the changes of luminance. For each VP2780-4K, the 0-256 gray-scale is adjusted to coincide with the Gamma 2.2 curve. Gray-Scale Tracking is then used to trace the status of the color temperature based on different gauges of Gray-Scale, allowing the monitor to display precise color through stable color temperature. In addition, each VP2780 is equipped with its own individual Color Calibration Factory Report which includes the complete information of the monitor and ensures a high performance of precise color.


Stunning Ultra HD 4K Resolution

Displaying more than 8 million pixels with a high pixel density of 163 PPI, this Ultra HD 3840×2160 monitor delivers the ultimate in image detail and clarity for stunning, lifelike images. In addition, with 4x more pixels than Full HD resolution, this Ultra HD monitor maximizes productivity by displaying more content.

SuperClear® AH-IPS Panel Technology

Enjoy accurate and vivid colors with consistent levels of brightness no matter your vantage point! With SuperClear® AH-IPS panel technology, this monitor delivers the same image quality whether you are looking at the screen from above, below, the front, or the side. SuperClear® AH-IPS panel technology also delivers the best colour performance and extends display viewing angles to 178 degrees both horizontally and vertically.


Incredible 10-bit and Delta E≤2 Color Accuracy

With impressive 10-bit color processing, this monitor can display up to 1.07 billion colors for professional-grade color accuracy and stunning images ideal for any multimedia application. Featuring Delta E≤2 color accuracy, this monitor reproduces phenomenal colors nearly imperceptible from real life for consistent and brilliant colors, every time.

Reviving Color with 100% sRGB Color Coverage

Accurate and consistent color performance is essential for professionals in graphic design, video editing, and other professional environments. With 100% sRGB color coverage capability, the VP2780-4K reproduces 100% sRGB rich color performance and captures images in their original and true colors.


Uniformity Enhancement for Consistent and Balanced Image Performance

The VP2780-4K’s Uniformity Correction function compensates any luminance and color uniformity imbalance on the screen such as dark spots, uneven brightness, or illegible images on the screen. With the ViewSonic uniformity correction function, gray-scale levels are balanced, and delta E scores are improved to be ≦2. Color reproduction, accuracy, and delta E numbers will all be improved, increasing reliability and offering the highest quality viewing experience from every monitor.

Independent 6-axis Color Adjustment Function

To deliver precise and accurate color performance, the independent 6-axis color adjustment function (red, green, blue, cyan, magenta and yellow) allows users to customize hue and saturation for each color axis individually, without affecting the other color outputs. In addition, the gain and offset functions allow users to control white balance for the upmost control when manipulating contrast and dark scenes.

14-bit LUT and 3D LUT Reproduces 4.39 Trillion Accurate Colors

The VP2780-4K adopts a 14-bit LUT and 3D LUT to convert image color from input signal to panel. The 14-bit LUT provides up to 4.39 trillion
