EIZO CG3145 Overview

True HDR

At 1000 cd/m2, the ColorEdge PROMINENCE CG3145 achieves the brightness necessary to display HDR content. With a contrast ratio of over 1,000,000:1, darker hues are reproduced with impressive depth in true black. The monitor supports the Hybrid Log Gamma and PQ Gamma HDR tone curves without an automatic brightness limiter (ABL). This allows images to be displayed with the correct brightness and color – for a true HDR experience. 

DCI 4K Resolution

The ColorEdge PROMINENCE CG3145 features DCI 4K resolution (4096 x 2160), which corresponds to a much higher pixel density than Full HD (1920 x 1080). This makes the HDR reference monitor the ideal tool for post-production.

Wide Gamut

Wide Gamut ensures that the two most common gamuts in post-production are covered: 99% of the DCI-P3 gamut and 80% of Rec.2020. In this way, colors are reliably displayed in accordance with industry requirements.

10-bit Color Depth

With 10-bit color depth based on a 24-bit LUT, the ColorEdge PROMINENCE CG3145 delivers more than a billion colors simultaneously. The color gradations are finer and the distances between adjacent colors (delta E) are lower.

Precise color rendering thanks to high-resolution 3D look-up table

The 3D LUT provides for the most precise tone value allocation possible and extremely exact color tone rendering, which is shown amongst other things in the gray scale. Brightness levels in relation to the image signal vary from module to module in LCDs and the color mixture (addition) of red, green, and blue also varies. This can be exactly determined and controlled only with the aid of specific measuring devices. EIZO therefore configures all of its monitors in the CG series and its colors and tone value curve in the factory. This results in a consistent color temperature over the entire gray scale. The result: The color reproduction is equal, precise, and reliable across each individual CG318-4K monitor.

The 3D look-up table also has the following benefits when working with films: Thanks to the ColorNavigation software included, you can emulate the colors of film material. This means you can see how the image will look when it is played. The 3D LUT also improves the additive mixture of color in the monitor (mixture of red, green, and blue). This is a key factor for displaying neutral gray tones correctly.

Color Management

"The ColorEdge PROMINENCE CG3145 supports the ColorNavigator NX quality control software from EIZO. ColorNavigator NX offers functionalities for client-side quality control and asset management of ColorEdge monitors. You can use this software to assign individual values – for brightness, white balance, or gamma settings, for instance – to specific projects, even if the values differ from the preset color mode. This calibration information is stored directly in the monitor.

ColorNavigator NX offers functionalities for quality control and asset management of ColorEdge monitors.


Constant tone value over the entire screen

Digital Uniformity Equalizer (DUE) controls all tone values over the entire monitor, pixel by pixel. The effect: color tones appear identical at each point on the screen, without the brightness fluctuations you experience in conventional LCDs. The DUE function also balances out the effects of fluctuations in ambient temperature on the color temperature and brightness. You will enjoy consistently even luminance distribution and perfect color purity. A real plus when touching-up images.

Stable brightness, no color deviation

The alpha and omega for exact image editing: constant brightness and color temperature. Patented electronics balance out brightness fluctuations that may arise due to extended periods of use and increased environmental and operating temperature. Thanks to a built-in thermometer, color deviations caused by fluctuations in room temperature are eliminated and automatically reduced. The color rendering remains absolutely constant over a long period of use, right from the start: because the warm-up time until brightness, color, and tone values have completely stabilized is just seven minutes. That is a quarter of the time normally required.

Port and Video Compatibility

Thanks to the HLG and PQ gamma curves, the ColorEdge PROMINENCE CG3145 meets the relevant standards for professional HDR post-production. It is also able to work with a wide range of formats, including 10-bit 4:2:2 at 50/60p via HDMI and 10-bit 4:4:4 at 50/60p via DisplayPort. 

For film production: 3D LUT profiles

Film emulation with 3D LUT ColorNavigator and ColorNavigator NX can use 3D LUT files from the color grading of films to generate data for emulation on the monitor. This film emulation is available for up to five color modes of the monitor and is suited to simulating the coloring of films.

Quick operation – even in dark rooms

Operation is easy and clear. The Button Guide, an overview function on the monitor, will show you the respective function keys above the control panel. The backlight keys mean that the monitor can even be used in dark environments. This is particularly helpful in dark post-production studios.

Exact color reproduction ex works

Brightness levels in relation to the image signal vary from module to module in LCDs and therefore the color mixture of red, green, and blue also varies. This can be exactly determined and controlled only with the aid of specific measuring devices. Therefore, EIZO configures the CG318-4K and its colors and tone curves with a widespread network of grid points and in each primary color. This results in a consistent color temperature over the entire gray scale.

Gamut Presets

Presets for the standard gamuts Rec. 2020, Rec. 709, DCI, PQ-Rec. 2100, PQ-Rec. 709, PQ-DCI, and HLG-Rec. 2100 are preinstalled. Users can directly, quickly switch between them at the touch of a button on the monitor.

Safely in sight thanks to the safe area marker

Ideal for captions and critical images: Thanks to the safe area marker, you will know which area of the screen is displayed on another output device. You will therefore see immediately whether subtitles, text, or other important image elements are in the visible area. So that the marker can be clearly.

Aspect Marker

The Aspect Marker enables the display of DCI 4k image areas (4096 x 2160 pixels) or 2K video material (2048 x 1080 pixels) that are displayed in varying ways when reproduced on different devices with differing aspect ratios.

4K Zoom

Users can quickly and easily make selections directly in the monitor menu to zoom in on various areas of the monitor image so as to assess details and sharpness. 

Luminance Warning

The Luminance Warning allows areas that exceed a certain brightness (300, 500, 1000, or 4000 cd/m2) when PQ mode is used to be highlighted. These areas can be highlighted in the user’s choice of yellow or magenta.

Gamut Warning

The Gamut Warning operates in two modes: Rec. 2020 image content that can’t be displayed in the Rec. 709 gamut is displayed in grayscale. Alternatively, clipping mode is simulated in Rec. 709 to show how Rec. 2020 material would look on HDTV devices.

Flicker-free working

The monitor is flicker-free at every brightness setting. This is implemented using the hybrid technology developed by EIZO to control the backlight. This combines the benefits of the otherwise standard PWM (pulse width modulation) and DC (direct current) control. The benefit: Your eyes do not get tired as quickly. You can work on the screen for an extended period.

Protection against glare thanks to the monitor hood

The monitor hood reduces reflection and brightness on the screen and helps protect your eyes. It is easy to attach and reduces the amount of light that hits the screen from above and from the sides.
