High Dynamic Range

HDR reference technology

The ColorEdge PROMINENCE CG3146 reference monitor means professionals in the television and film industry can rest assured that the image they see is 100% accurate. All monitors are calibrated at EIZO’s own factory in Japan, which means that each and every monitor provides an accurate display of images and is ideally suited for post-production work. This factory calibration includes the commonly used SDR and HDR standards. BT.2020, BT.709, DCI P3, PQ_BT.2100, PQ_DCI P3 and HLG_BT.2100 are among the available reference modes for calibration. The ColorEdge PROMINENCE CG3146 from EIZO displays true HDR in reference quality without automatic brightness limitation or local dimming. This guarantees that each pixel has the correct colour and brightness.


Gamma curves

The ColorEdge PROMINENCE CG3146 supports both of the gamma curves for HDR video: the HLG curve (Hybrid Log Gamma) and the PQ curve (Perceptual Quantization). Both are precisely calibrated to reference class 1 level. The HLG curve is compatible with SRD displays, making it suitable for live TV broadcasts, for example. The PQ curve is closer to the colour and brightness perception of the human eye and is often used for films, streaming and other video content. Both gamma curves were defined as standards by the International Telecommunication Union (ITU) published as the ITU-R Recommendation BT.2100. The PQ curve is also known as the ST-2084 standard for the Society of Motion Picture and Television Engineers (SMPTE).


and video-mastering

High brightness and impressive contrast

At 1000 cd/m2, the ColorEdge PROMINENCE CG3146 achieves the high brightness necessary to display HDR content. It displays deep black tones with a typical contrast ratio of 1000000:1. All code values of HDR-HLG or HDR-PQ brightness levels are reliably reproduced on the monitor at reference class 1 level.


DCI 4K resolution

The ColorEdge PROMINENCE CG3146 supports DCI 4K resolution (4096 × 2160), making it ideal for creating, editing and referencing with 2D and 3D CGI, VFX projects, compositing and color grading.

Video compatibility

The monitor supports different video formats, such as HDMI signals with 10-bit 4:2:2 at 50/60 p. It supports DisplayPort signals with up to 10-bit 4:4:4 at 50/60 p. Overview of compatible resolutions.

SDI ports

The ColorEdge PROMINENCE CG3146 is equipped with a single-link 12G/6G/3G/HD SD and dual- or quad-link 3G/HD SDI ports that enable you to use 4K video signals. The SDI ports support the 2SI process (2 Sample Interleave), which ensures that the image consistently remains stable during transmission. VPID data (Video Payload ID) for SDI ports are also supported.

Flexible connection options

The CG3146 offers flexibility in connection options for a wide variety of other video equipment and computers thanks to an HDMI and a DisplayPort input, which are easily accessible on the side of the monitor. There are also four downstream USB ports and one upstream USB port.

Precision and color accuracy

High-contrast, bright and crisp screen

Integrated measurement sensor for automated workflows

A reference monitor always needs to be precisely configured in terms of white balance, colour and EOTF. The ColorEdge PROMINENCE CG3146 is the world’s first HDR reference monitor that is equipped with a built-in measurement sensor that automatically recalibrates the monitor to the reference class level.

Each individual built-in sensor is correlated at the factory with a precision lab measurement sensor and calibrated to ‘its’ monitor in order to provide the exact measurement result. In addition, the sensor can be correlated to other measurement sensors that are used in existing user workflows. Thanks to the built-in measurement sensor, there is no longer a need for third-party calibration equipment. This simplifies quality control and the user can concentrate on the creative process. The calibration settings are saved directly in the monitor so that it does not have to be recalibrated when it is connected to another computer.

Effortless quality control

The built-in measurement sensor can be configured to automatically recalibrate the monitor at predefined times. For example, you can choose a time at night or the weekend to prevent interruptions while users are at work. This ensures consistently accurate colour representation on the monitor. The monitor warms up automatically, the measurement sensor is folded out and the recalibration is performed, even if the computer or other source is switched off.

If desired, the monitor’s own calibration sensor can be calibrated using an external measurement sensor. The following devices are supported:

Colorimetry Research: CR-100, CR-250, CR300
Klein: K-10/K-10A
Konica Minolta: CS-1000, CS-1000A, CA-210, CA-310, CA410, CS-2000, CS-2000A, CS-200
Photo Research: PR-655, PR-680
JETI: Specbos 1211, Spectraval 1501

ColorNavigator color management software

EIZO ColorNavigator is the calibration and quality control software for colour management workflow monitors in the ColorEdge series. The proprietary software simplifies the recalibration process and produces reliable results for colour-accurate display.


Wide gamut

The wide gamut reproduces 99% of the DCI P3 standard that is typically used in post-production, which displays colours true to the original source data.

10-bit display

The ColorEdge PROMINENCE CG3146 offers 10-bit display* based on a 24-bit look-up-table (LUT), which can display more than one billion colours. This results in finer gradations and a lower colour distance (delta E) between adjacent hues.

* This requires a graphics board and software that support 10-bit display.

Precise color reproduction thanks to high-resolution 3D LUT

Hues are precisely addressed in a cubic RGB table thanks to the built-in 3D LUT. The 3D LUT also improves the monitor’s additive colour mixing (mixing of RGB) – a key factor for ensuring correct display of neutral grey tones.

Stable display thanks to industry-leading AI

To ensure gradations, colour, brightness and other characteristics are always accurately displayed even when the ambient temperature changes, the ColorEdge CG3146 is equipped with a temperature sensor. It accurately measures the monitor’s internal temperature, while an AI (artificial intelligence)-assisted correction algorithm* distinguishes between different temperature change patterns and calculates a precise adjustment in real time.

* Patent pending

Stable color reproduction in just three minutes

It takes a traditional monitor a minimum of 30 minutes for the brightness, chromaticity and tone values to stabilise, whereas the ColorEdge CG3146 only needs three minutes. It means that users know they can reliably trust the colours of the monitor within a short time after switching in on.

Typical monitor

Perfect rendering across the entire screen

Digital Uniformity Equalizer

Each individual monitor panel is precisely measured over the entire surface at the EIZO factory. Any inhomogeneities in brightness and unnecessary colour are detected and removed. This process (Digital Uniformity Equalizer) guarantees that identical colours always look the same over the entire service life of the monitor, no matter where they are displayed. Only in this way is precise image processing and retouching possible.

Easy to use

Features for greater comfort

Adjustable front dial

The CG3146 has a dial on its front bezel that can be used to customise the monitor settings to your needs, such as by assigning it to the brightness settings, making navigation quick and easy.

For the sake of the eyes

Flicker free

The ColorEdge PROMINENCE CG3146 regulates the brightness for flicker-free viewing to retain colour stability, for example, despite LED backlighting. This is beneficial as it alleviates strain on the user’s eyes. You can work at your screen for longer periods.

Protection against reflections and glare

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.

EIZO monitors generally have two or more signal inputs. You can easily switch between two or more computers by pressing a button on the front of the monitor. For devices with KVM switch functionality, the USB hub also switches to the respective computer at the same time.

This may be a problem with the graphics card driver. Please install the latest driver for your graphics card and restart the PC with the monitor.
Older graphics cards may not be able to display this resolution. In this case, you will require a new graphics card with the matching output.

Firstly, please check the resolution of the LCD screen. Check the recommended resolution stated for the respective LCD screen. If you have set a lower resolution than recommended, this may result in blurring.

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.

The color temperature is a benchmark for measuring the white tone and is stated in Kelvin. At high temperatures, the white tone appears slightly blue, while it has a more red tone at low temperatures.
5000 K: Often used in the printing industry.
6500 K: Suitable for displaying photos and video images.

The color tone rendering is relative to the change of the input signal level. This relationship is generally known as the gamma characteristic. In image reproduction, low gamma values result in white images and high gamma values result in high-contrast images.

International standard for an RGB color space. A color space has been defined, which most devices can comply with, to enable color matching between various applications and devices, such as monitors, scanners, and digital cameras. sRGB images, which are detected or issued on "sRBG devices" are limited to the full sRBG color range and no colors outside the sRBG color space. Color allocation, white point, and gamma are permanently defined.

In connection with a USB-compatible computer, the monitor acts as a hub, to which other USB-compatible peripherals can be connected.

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 perpendicular 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.
