ColorEdge PROMINENCE CG3145HDR logo
31.1" (79 cm) HDR Reference Monitor
This HDR reference monitor is the first to overcome the severe drawbacks of other HDR technologies that are available in the market today so it can be used reliably for professional post production work. It supports both HLG and PQ gamma curves in order to display content that approximates the human perception of color and light, making it ideal for color grading in the HDR video workflow.

High Dynamic Range

What is HDR?

HDRHDR (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  HDR reference monitor, ColorEdge PROMINENCE CG3145, is the first monitor to overcome the severe drawbacks of other HDR technologies that are available in the market today so it can be used reliably for post production work.

Auto Brightness Limiter (ABL) is equipped in other HDR OLED monitors and limits the monitor's ability to display lighter scenes with tones over a specific range in order to prolong the device's lifetime. This causes those light areas to appear dimmer and the color 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 color accuracy in smaller details.

ColorEdge PROMINENCE CG3145

EIZO's ColorEdge PROMINENCE CG3145 achieves a true HDR visual experience without ABL or the "halo" effect to ensure you always see accurate colors and brightness in every pixel.

Gamma Curves

CG3145 and HDR logoThere are 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 color 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. ColorEdge PROMINENCE CG3145 supports both HLG and PQ curves.

 

Features for Video Editing and Post Production

High Brightness and Contrast

ColorEdge PROMINENCE CG3145 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.

DCI 4K Resolution

ColorEdge PROMINENCE CG3145 displays the DCI-4K standard (4096 x 2160) which is more than four times that of full HD (1920 x 1080). It's ideal for creating, editing, and referencing with 2D and 3D CGI, VFX, compositing, and color grading.

Centralized Color Management

ColorEdge PROMINENCE CG3145 supports EIZO's unique ColorNavigator NX quality control software. It offers quality control and asset management of client ColorEdge monitors. To suit the needs of a specific project, you can change the brightness, gamma, and white point settings of the monitor's preset color modes and calibrate to the new values. The calibration information is saved directly to the monitor.

Video Compatibilities

The monitor supports various video formats including HDMI compatible with 10-bit 4:2:2 at 50/60p. DisplayPort supports up to 10-bit 4:4:4 at 50/60p.

Wide Color Gamut

cg3145-color-gamut.jpgThe wide gamut faithfully reproduces 99% of the DCI-P3 standard used in post production.

 

 

 

 

 

 

 

10-Bit Simultaneous Display

With 10-bit simultaneous display* from a 24-bit look-up-table (LUT), ColorEdge PROMINENCE CG3145 can show more than one billion colors simultaneously. This results in smooth color gradations and reduced Delta-E between two adjacent colors.

*A graphics board and software which support 10-bit output are also necessary for 10-bit display.

Uniformity from Corner to Corner

Fluctuations in brightness and chromaticity on different parts of the screen are a common trait of LCD monitors. To counteract this, the ColorEdge PROMINENCE CG3145 is equipped with EIZO's patented digital uniformity equalizer (DUE) technology to ensure stable image display and counterbalance the influences that a fluctuating temperature may have on color temperature and brightness for stable image display.

DUE

Multiple Preset Color Modes

Color ModesThe ColorEdge PROMINENCE CG3145 provides quick access to several broadcast-standard preset color modes via a button on the front of the monitor. The available modes are REC2020, REC709, DCI, PQ_REC2100, PQ_REC709, PQ_DCI, HLG_REC2100, and Calibration.

 

 

 

 

 

Luminance Warning

The ColorEdge PROMINENCE CG3145 includes a PQ Clipping function that shows the areas of an image which display at brightness levels higher than the current setting. The areas which cannot be displayed at the correct brightness with the current settings are shown in yellow or magenta. PQ Clipping can be viewed for brightnesses of 300, 500, 1000, and 4000 cd/m2.

Safe Area MarkerSafe Area Marker

A safe area mareker designates the area of the screen that will be shown on any display device. This allows you to confirm that subtitles and other text will be visible in various viewing environments.

 

 

 

 

Aspect Marker

An aspect marker designates the areas of the screen size that will be shown on a display device when you input DCI 4K (4096 x 2160) or DCI 2K (2048 x 1080). This allows you to confirm how the screen size and composition of the scene will appear in other viewing environments.

4K Zoom Function

Enlarge areas of the screen to confirm small details and check focus accuracy in images using the 4K zoom function. It is quickly and easily accessible using the monitor's front buttons.

Zoom Function

Rec. 709 Out of Gamut Warning

The monitor includes a Gamut Warning preset. When selected, the areas of a Rec. 2020 image that cannot be reproduced using Rec. 709 are clearing indicated by converting them to shades of gray. An additional mode called Rec. 709 Clipping allows the editor to view Rec. 2020 images within the Rec. 709 color space, simulating how it would look to their audience in an HDTV environment.

Features for Comfort and Ease-of-Use

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 CG3145 regulates brightness to make flicker unperceivable without any drawbacks like compromising color stability.

Multiple Inputs

With a single cable, the DCI-4K resolution at 60 Hz is supported by both DisplayPort and HDMI inputs.

Monitor hoodLight-Shielding Hood

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

 

 

Adjustable Stand

The monitor comes with a stand that offers heigh adjustment up to 116 cm as well as swivel. Adjustable stand

Built-In Carrying Handles

Two handles on the back allow for a firm grip when carrying the monitor.
