Features for Working in 4K HDR

Enhanced Display Quality

The CG3100X offers exceptional visual performance with high brightness, high contrast, and HDR support. Featuring a brightness level of 500 cd/m² and a contrast ratio of 1800:1*, the monitor meets DCI standards to ensure content is displayed clearly with added depth and detail.

For HDR content, the monitor supports the gamma (EOTF) compatible hybrid log-gamma (HLG) transfer function for broadcasting and perceptual quantization (PQ) curve for production of films and streamed content. Additionally, users can set any camera log using colourNavigator 7 to view the camera log video on the monitor during filming.

*Typical value when DUE Priority is set to "Brightness".
EOTF stands for Electro-Optical Transfer Function.
HLG and PQ were standardized by the International Telecommunication Union (ITU) as ITU-R BT.2100. PQ was standardized by the Society of Motion Picture Television Engineers (SMPTE) as ST-2084.

DCI 4K Resolution Across a 30.5-inch Screen

The CG3100X displays at DCI 4K resolution (4096 x 2160) which is more than four times that of Full HD (1920 x 1080). This makes it an optimal solution for creating, editing, and referencing 2D and 3D CGI, VFX, compositing, and colour grading.

Colour Precision

Industry Standard colour Reproduction with Broadcast and Cinema Presets

The monitor's wide colour gamut covers 99% of the DCI-P3 standard used in digital cinema and supports the BT.2020 standard used in broadcasting for exceptionally faithful reproduction of colour. It also covers 97% of the Adobe RGB colour space so images and video shot in Adobe RGB will be displayed correctly. colour mode presets can easily be changed via the switches on the front of the monitor, enabling straightforward colour management for each project.

10-Bit Simultaneous Display

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

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

3D LUT for Accurate colour Display

The monitor is equipped with a 3D LUT (look-up table) which adjusts colours on an RGB cubic table. Using colourNavigator 7's film emulation function, users can emulate film colour properties using a 3D LUT file.

Built-In Sensor to Automate Your Workflow

The monitor's built-in sensor can be set to calibrate the monitor automatically at designated times. This eliminates the need for a third-party calibration device and ensures your screen stays colour-accurate. In addition, the sensor swings onto the screen, taking up minimal space and allowing you to continue working even during calibration.

ColourNavigator 7 colour Management Software

EIZO's proprietary free colourNavigator 7 software is the complete colour management solution for reliable calibration and quality control of colourEdge monitors. It offers multiple preset colour modes, simultaneous calibration of all modes, and automatic recalibration to ensure consistent colour accuracy. It also allows calibration targets to be set for brightness, white point, gamma (EOTF), and colour gamut for more fine-tuned control.

ColourNavigator Network Quality Control Software

EIZO's colourNavigator Network provides centralized quality control of colourEdge monitors for studios with multiple creators and editors working on shared projects. An administrator can set the colour modes, schedule automatic self-calibration for monitors with built-in sensors, register or adjust asset management settings, and more - all carried out remotely over the network. For large-scale projects, this ensures that the appropriate colour standards are used at every step and saves hundreds of hours spent on calibration and maintenance.

Comfortable Design, Advanced Connectivity

Sleek Design, Quiet Operation

The CG3100X features a sleek design with punched metal on the back, enhancing airflow for effective heat management. Its internal fan operates at just 20 dB, ensuring a quiet workstation environment.

DCI 4K/60p Support

The monitor's DisplayPort™ and HDMI inputs support up to DCI 4K at 60p 4:4:4 10-bit and 12-bit, respectively. This ensures smooth and fluid motion with precise colour representation for video editing and post production work.

FRL Support for High-Speed Transmission

The CG3100X supports Fixed Rate Link (FRL), the latest signal technology supported in the latest HDMI specification. FRL is required to receive 12-bit signals, handle higher uncompressed high-resolution data, such as 4K, and take advantage of high-speed bandwidths for compressed video transport over an HDMI connection. The monitor comes bundled with an Ultra High Speed HDMI Cable for reliable 4K performance.

Single Cable Connection with USB Type-C

The monitor is equipped with a USB Type-C port for streamlined connection with laptops or creative workstations. With a single cable, users can display video, access the monitor’s multi-port USB hub, and charge their device with up to 94W of power delivery. This helps maintain a tidier workspace and offers stable network access via the built-in LAN port.

Headphone Jack for Direct Audio Output

The CG3100X features a headphone jack for conveniently checking audio content.

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 is lightweight and easily attaches magnetically without needing separate parts.

Functions for Editing and Post Production

Pixel Inspection

Pixel Inspection, operated through the monitor's OSD, shows the colour information of a pixel from the source input data and the data as it is displayed on the monitor. System managers can use this to verify that creators’ technical settings match project parameters, reducing costly rework and ensuring consistency across remote teams.

Check PQ Contents at Any Brightness Level

The monitor offers an optional PQ gamma curve (EOTF) function that allows the input signal to be clipped or compressed to fit within the luminance value of the monitor. The Auto setting under PQ Option menu automatically adjusts the PQ curve according to the monitor's current brightness.

Sync Signal

The Sync Signal function automatically switches colour settings — brightness, gamma (EOTF), and colour gamut — according to the metadata of the input signal. This ensures accurate settings are always applied when switching between multiple projects.

Nearest Neighbors Interpolation

The CG3100X offers Nearest Neighbour interpolation for image scaling and resampling. When upscaling, Nearest NeighboUr copies and aligns pixels for precise colour fidelity, while the alternative interpolation mode blends pixels for smoother tones. Editors can select the desired method via the monitor's OSD.

Luminance Warning

The PQ Option function allows you to check PQ content at any brightness level and highlights clipped areas in yellow or magenta for easy identification.

4K Zoom

The 4K zoom function allows users to enlarge screen areas to check fine details and focus accuracy. It is quickly accessible via the monitor’s front switches.

BT.709 Out-of-Gamut Warning

The monitor includes a Gamut Warning mode that indicates areas of a BT.2020 image that cannot be reproduced in the BT.709 colour space by displaying them in shades of gray. The BT.709 Clipping mode simulates how the image appears in an HDTV environment.

Markers for Information Overlay

The CG3100X features marker functions to ensure that text or graphics are correctly positioned on the screen. The Safe Area Marker defines visible regions for captions or overlays, and marker size and position can be customized to project requirements.

Stable Image Display

Adjusted at the Factory for Smooth colour Gradations

Each colourEdge monitor is factory-calibrated by measuring R, G, and B gamma values from 0 – 1023, then using the 24-bit LUT to select the most appropriate tones. This ensures smooth, accurate colour gradations across all tones.

Uniformity Across the Screen

ColourEdge monitors feature EIZO’s patented digital uniformity equalizer (DUE) technology, correcting deviations in brightness and chromaticity across the screen for consistent and stable image display.

Stable Display Using Industry-First AI

Equipped with a temperature sensor, the monitor adjusts in real time to maintain accurate colour and brightness as ambient temperature changes. Its AI algorithm detects temperature patterns for even more precise correction. ・Japan patent no. 6723964
