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).

Video-editing and 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 colour 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.

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.

Image and colour accuracy

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 colour management workflow 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 colour reproduction using 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 of industry-leading AI

The ColorEdge PROMINENCE CG3146 is equipped with a temperature sensor to make sure that gradations, colours, brightness and other characteristics are always displayed with total accuracy, even if the ambient temperature changes. It precisely measures the monitor’s internal temperature while an AI algorithm* differentiates between different temperature change patters and calculates a precise adjustment in real time.

* Patent pending

Stable colour 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 PROMINENCE 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.

* Based on internal testing at EIZO.

Homogeneity across the entire screen

LCD monitors often have inhomogeneous brightness and colour representation on the screen surface – which impairs colour accuracy. To counteract this, EIZO has equipped the ColorEdge PROMINENCE CG3146 with its patented DUE (Digital Uniformity Equalizer) technology. It corrects for these variations in every hue, anywhere on the screen, ensuring stable viewing.

Additional features and functionalities

Default colour modes

The OSD menu of the ColorEdge PROMINENCE CG3146 offers quick access to the reference modes, which correspond to different playback standards. The available modes are BT.2020, BT.709, DCI P3, PQ_BT.2100, PQ_DCI P3, HLG_BT.2100, Calibration and Sync Signal.

Automatic colour settings

The ColorEdge PROMINENCE CG3146 offers Sync Signal functionality, which adjusts monitor settings such as signal range and colour format to the video signal, offering consistent colour settings during the entire production process.

PQ and HLG brightness warning

The ColorEdge PROMINENCE CG3146 features a brightness warning in case image areas cannot be properly displayed with the current brightness settings. These areas are highlighted in the user’s choice of yellow or magenta and can be displayed for typical HDR brightness levels of 300, 500, 1000 or 4000 cd/m².

BT.709 gamut warning

When enabled, a BT.709 gamut warning ensures that areas of a BT.2020 image that cannot be reproduced in the BT.709 gamut are displayed in greyscale. A BT.709 clipping mode also allows BT.2020 images to be displayed within the BT.709 gamut, thus simulating how they would look on HDTV devices.

4K zoom

4K zoom functionality enables you to zoom in on specific areas of the monitor in order to conveniently check image detail and focus accuracy. The functionality can be quickly and easily accessed using the buttons on the monitor’s bezel in the front.

Aspect Marker

The CG3146 displays up to three types of markers at the same time. The position and size of each marker can be defined by aspect ratio, pixel (centre) and pixel (free). Width, height, priority and colour of each marker can be freely selected.

Blue-only functionality

The CG3146 offers a blue-only functionality that can be used to check noise in the signal. A monochrome image that uses only the blue components of the input signal will be displayed.

D065 (CRT) support

The CG3146 is capable of using an offset value for white balance/colour temperature that corresponds to the display on a CRT monitor.

User-friendliness and ergonomics

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.

Flicker-free viewing

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.

Monitor hood

A monitor hood is included in the delivery. It prevents ambient light from producing reflections on the monitor. The monitor hood is magnetic and can be attached/detached quickly and conveniently.

Built-in handles

You can conveniently carry or move the monitor thanks to two handles on the back of the device.
