High Dynamic Range

What is HDR?

HDR (High Dynamic Range) is a range that approximates the human perception of color and light as content is shown on a display device. A monitor which 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 color are lost when displaying HDR content.


EIZO HDR Technology

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 color duller as a result.
EIZO HDR Technology

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 color accuracy in smaller details.
HDR Monitor with Local Dimming

EIZO's ColorEdge PROMINENCE CG3146 achieves a true HDR visual experience without ABL or Local Dimming to ensure you always see accurate colors and brightness in every pixel.

HLG and PQ Curve

ColorEdge PROMINENCE CG3146 supports hybrid log-gamma (HLG) and the perceptual quantization (PQ) curve for HDR video. HLG is compatible with SDR displays and is suitable for live television broadcasting. The PQ curve approximates the human visual system in terms of color and light perception, making it ideal for films, streaming, and other video content. Both functions (EOTF) 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.

Simple and Precise Color Management

Built-In Sensor to Automate Your Workflow

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 color accurate. This eliminates the need for a third-party calibration device and streamlines color 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.

Built-In Sensor to Automate Your Workflow

Stable and Accurate Display

Wide Color Gamut

The wide gamut faithfully reproduces 99% of the DCI-P3 standard used in post production for faithful reproduction of color.

Wide Color Gamut

10-Bit Simultaneous Display

The ColorEdge CG3146 offers 10-bit simultaneous display* from a 24-bit look-up-table (LUT) which means it can show more than one billion colors simultaneously. This is 64 times more colors than you get with 8-bit display, resulting in smooth color gradations and reduced Delta-E between two adjacent colors.

10-Bit Simultaneous Display

*A graphics board and software which support 10-bit output are also necessary for 10-bit display. Equipment that supports DeepColor is required for 10-bit display when connected via HDMI.

3D LUT for Accurate Color Display

A 3D LUT is included which adjusts colors individually on an RGB cubic table. The 3D LUT also improves the monitor's additive color mixture (combination of RGB), which is a key factor in its ability to display neutral gray tones.

 3D LUT for Accurate Color Display

Stable Display Using Industry-First AI

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.

Stable Display Using Industry-First AI


Stable Color in Just 3 Minutes

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 reliable color display soon after turning the monitor on.
*Based on EIZO's internal testing.

Stable Color in Just 3 Minutes


Uniformity Across the Screen

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.

Uniformity Across the Screen

BT.709 Out of Gamut Warning

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.
 BT.709 Out of Gamut Warning


Pixel Inspection

Working within the wrong parameters affects the creator’s editing decisions, potentially requiring significant rework of the project and causing costly delays in production schedules. Pixel Inspection, operated through the monitor's OSD, shows the color information of a pixel from the source input data and the data as it is displayed on the monitor.                   


System managers can use this information to verify that the creator's technical settings match the current project's predefined color parameters. This is especially helpful when creators are working remotely and system managers cannot verify settings directly. By ensuring that creators are working under the appropriate technical conditions, studios can reduce the likelihood of project rework due to mismatched technical settings.


Pixel Inspection requires the latest firmware. Download it here.

Comfort and Ease-of-Use

Adjustable Front Dial

The monitor's front bezel includes a dial for quickly and easily navigating the OSD menu or adjusting monitor settings, such as brightness.

Flicker-Free Viewing

Due to the way brightness is controlled on LED backlights, a small number of people perceive flicker on their screen which causes eye fatigue. The ColorEdge PROMINENCE CG3146 regulates brightness to make flicker unperceivable without any drawbacks, such as compromising color stability.


Light-Shielding Hood

The monitor comes bundled with a light-shielding hood that effectively prevents glare on the screen caused by ambient lighting. The hood attaches magnetically for quick and easy setup.
