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.
High Dynamic Range
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
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.
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.
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.
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
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.
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
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
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.
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.
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
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.
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
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.
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.
User-friendliness and ergonomics
Our quality promise
All components of the monitor, including the LCD panel, are covered by a five-year manufacturer’s warranty* (repair work performed at the Service Centre). This is made possible by a highly developed manufacturing process, which derives its success from one straightforward principle: innovative and sophisticated monitor technology manufactured from high-quality materials and strict quality control in the EIZO factory.
* Maximum of 30 000 hours of monitor usage time (10 000 hours of monitor usage time for the LCD panel).
