The EIZO CG3146 - HPA award-winning HDR video reference monitor for engineering excellence.
The PROMINENCE CG3146 is the first true HDR reference monitor in the world to incorporate a built-in calibration sensor, delivering the ultimate in colour-accurate HDR video monitoring.
With a 31 inch with native 4K DCI resolution, this reference monitor is ideal for 2D and 3D CGI, VFX, Compositing, and Colour Grading.
HDR (High Dynamic Range) is a range that approximates the human perception of colour and light as content is shown on a display device. A monitor that supports HDR is able to correctly show both very bright and very dark areas on the screen without sacrificing the integrity of either. With lower-range SDR (Standard Dynamic Range) monitors, brightness, contrast, and colour are lost when displaying HDR content.
At 1000 cd/m2, the ColorEdge PROMINENCE CG3146 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 colour – for a true HDR experience.

EIZO's ColorEdge PROMINENCE HDR reference monitors are the first to overcome the severe drawbacks of other HDR technologies available in the market, so they can be used reliably for post-production work.
Auto Brightness Limiter (ABL) equipped in other HDR OLED monitors limits the monitor's ability to display lighter scenes with tones over a specific range. This causes those light areas to appear dimmer and the colour duller as a result.
Local dimming uses an area control backlight system which adjusts the brightness in sections of the screen depending on the content displayed. However, when an object on the screen falls outside of the area of the backlight that is adjusted, a "halo" effect appears, making it impossible to achieve full colour accuracy in smaller details.
EIZO's ColorEdge PROMINENCE CG3146 achieves a true HDR visual experience without ABL or Local Dimming to ensure you always see accurate colours and brightness in every pixel.
ColorEdge PROMINENCE CG3146 supports two gamma curves used for HDR video – hybrid log-gamma (HLG) and perceptual quantization (PQ) curve. HLG is compatible with SDR displays and is suitable for live television broadcasting. PQ curve approximates the human visual system in terms of colour and light perception, making it ideal for films, streaming, and other video content. Both gamma curves were standardized by the International Telecommunication Union (ITU) as ITU-R BT.2100. In addition, the PQ curve was standardized by the Society of Motion Picture and Television Engineers (SMPTE) as ST-2084.
The ColorEdge PROMINENCE CG3146 is the first HDR reference monitor in the world to be equipped with a built-in sensor which calibrates the monitor to stay colour accurate. This eliminates the need for a third-party calibration device and streamlines colour management so you can stay more focused on the creative process. Calibration information is saved directly to the monitor, so you do not need to recalibrate if connecting to more than one PC.
ColorNavigator 7 is the latest calibration and quality control software for ColorEdge color management monitors. It combines all the features of EIZO's previous color management software, ColorNavigator 6 and ColorNavigator NX, to create a new and improved solution for creatives in a range of fields. The proprietary software makes calibration simple and produces predictable results for photography, design, print, and video creation.
ColorEdge PROMINENCE CG3146 achieves the 1000 cd/m2 high brightness level needed for HDR content display. It also offers a typical contrast ratio of 1,000,000:1 for displaying true blacks.
ColorEdge PROMINENCE CG3146 displays the DCI-4K standard (4096 x 2160) which is more than four times that of full HD (1920 x 1080). It is ideal for creating, editing, and referencing with 2D and 3D CGI, VFX, compositing, and colour grading.
The ColorEdge PROMINENCE CG3146 is equipped with a Single-Link 12G/6G/3G/HD-SDI and Dual- or Quad-Link 3G*/HD-SDI connections for seamless transmission of 4K video data. The SDI connections support 2SI (2 sample interleave) to ensure picture is always maintained during transmission. VPID (Video Payload ID) is also supported for SDI connections.
*2 sample interleave supported.
HDMI and DisplayPort Inputs
Furthermore, the monitor has an HDMI and DisplayPort input located conveniently on the side of the monitor for flexible connection to a range of other video devices. Four USB downstream ports and one upstream port are also equipped.
Video Compatibilities
The monitor's HDMI and DisplayPort inputs support DCI 4K at 60p. HDMI input supports 12-bit 4:2:2 at 50/60p and DisplayPort input supports up to 10-bit 4:4:4 at 50/60p.
The color and brightness of an LCD monitor can shift due to changes in ambient temperature and the temperature of the monitor itself. ColorEdge CG Series monitors are equipped with a temperature sensor for accurately measuring the temperature inside the monitor, as well as estimating the temperature of the surrounding environment. With this temperature sensing and estimation technology, the monitor adjusts in real-time so gradations, color, brightness, and other characteristics continue to be displayed accurately. Furthermore, EIZO uses AI (artificial intelligence)* in the estimation algorithm of the CG3146 so it can distinguish between various temperature changing patterns to calculate even more accurate correction.
*Patent pending.

A typical monitor takes 30 minutes or more for its brightness, chromaticity, and tone characteristics to stabilize. The ColorEdge PROMINENCE CG3146 takes a mere 3* minutes so you get a reliable color display soon after turning the monitor on.
LCD monitors commonly exhibit fluctuations in brightness and chromaticity across the screen, affecting color accuracy. To counter this, ColorEdge monitors are equipped with EIZO's patented digital uniformity equalizer (DUE) technology which corrects deviations in every tone across the screen to ensure stable display.
Added Functionality -
The ColorEdge PROMINENCE CG3146 provides quick access to several broadcast-standard preset color modes from the OSD menu. The available modes are BT.2020, BT.709, DCI-P3, PQ_BT.2100, PQ_DCI-P3, HLG_BT.2100, Calibration, and SYNC_SIGNAL.
To ensure color settings stay consistent throughout production, the ColorEdge PROMINENCE CG3146 includes a Sync Signal function which automatically adjusts the monitor's settings, such as input range and input color format, according to the video signal.
The ColorEdge PROMINENCE CG3146 includes a function that shows the areas of the image that cannot be displayed correctly at the current brightness settings. These areas are marked in yellow or magenta and can be viewed for brightnesses of 300, 500, 1000, and 4000 cd/m2.
The monitor includes a Gamut Warning preset that when selected, indicates areas of a BT.2020 image that cannot be reproduced using BT.709 by converting them to shades of gray. An additional mode called BT.709 Clipping allows the editor to view BT.2020 images within the BT.709 color space, simulating how it would look to their audience in an HDTV environment.
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.
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.
With 10-bit colour depth based on a 24-bit LUT, the ColorEdge PROMINENCE CG3145 delivers more than a billion colours simultaneously. The colour gradations are finer and the distances between adjacent colours (delta E) are lower.
The 3D LUT provides for the most precise tone value allocation possible and extremely exact colour 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 colour 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 colours and tone value curve in the factory. This results in a consistent colour temperature over the entire gray scale. The result: The colour reproduction is equal, precise, and reliable across each individual CG3146 monitor.
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.

Without DUE
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.
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.
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.
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.
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.
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 seen in all images, you can change the marker color.
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.
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.
