10 bit color rendering

In connection with a frame rate control (FRC) of the LCD modules, CG monitors allow for 10 bit color resolution, depending on the module. Screens can therefore display even the finest tone value gradations using a billion colors. This requires corresponding 10 bit support by the application software and graphics card.

16 bit look-up table

When it comes to color accuracy when working, how well a monitor can differentiate between color tones is of fundamental importance. To achieve the maximum color depth and prevent the formation of stripes, banding, and washing, EIZO relies on the ultimate perfection: a 16 bit look-up table (LUT) ensures precise color resolution, meaning that even the finest structures in darker areas of the image are reproduced so that they are absolutely accurate in every detail.

3D-LUT

Typical 1D look-up tables (LUTs) have separate tables for red, green and blue. Depending on the model, EIZO links the color allocation to a single, three-dimensional look-up table (3D LUT) to ensure particularly accurate color control and in doing so, allows for the exact addition of primary colors to any chosen color tone – vital technology for the ideal gray scale and ultra-precise color reproduction.

Resolution

The LCD display is comprised of a fixed number of image elements (pixels), which light up to display the contents of the screen. The image is comprised of horizontal and vertical pixels. LCDs achieve the best image quality if all pixels can be allocated data, i.e. if the resolution configured on the computer corresponds to that of the LCD display.

Auto EcoView

Thanks to the automatic brightness adjustment, an EIZO monitor with Auto EcoView saves up to 50% energy in comparison to inactive brightness adjustment. The EcoView sensor identifies changes to the ambient light, whereupon the image brightness of the monitor is calibrated and adjusted to the new light conditions. In the case of strong lighting, the image brightness is increased, while it is reduced in the case of weak lighting. The continuous adjustment of the light conditions results in a constant contrast, which ensures maximum ergonomics at the workplace.

Viewing angle

The viewing angle relates to the angle, beneath which the contrast is better than 10:1. These are normally values of 160° to 178°. These values do not provide any information about what enormous differences in contrast may result within the viewing angle. The contrasts should not change significantly for users with a vertical view and a slightly side-on view. It must not make a difference whether the viewer is looking at the middle of the image or the edge of the image. How much the contrast stability varies with different LCD technologies is best checked using a measurement diagram or by a direct visual comparison. The more stable the contrast in the user's viewing frustum, the better the image rendering.

Colorimeter

A device to measure light colors. Colorimeters are mainly used for calibrating and profiling monitors. In any case, body colors (reflected light) can be measured to a limited extent.

ColorNavigator

Calibration software included with EIZO ColorEdge LCD monitors It ensures interactive control of the look-up tables in the screen and creates a corresponding monitor color profile.

CUD

Color Universal Design mode simulates the way color blind people view things – for example when designing websites or orientation systems.

Digital Uniformity Equalizer (DUE)

Homogeneous luminance distribution and good color purity are key to achieving very accurate image rendering. The Digital Uniformity Equalizer (DUE) circuit takes care of this. It automatically corrects non-uniformities in terms of luminance and chrominance for all tone values across the entire image area – pixel by pixel.
