Confused about HiDPI and Retina display? ― Understanding pixel density, an essential element in choosing displays in the age of 4K


Quadruple the Resolution of Full HD. And Then Some.

DCI 4KThe ColorEdge CG318-4K 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.


Large 31.1" Screen

Whether you are creating, editing, or checking your work, this screen offers ample space to focus on 4K content. At a dense 149 ppi, it’s suited for not only video but also photo retouching and printing.

CG318-4K gamutReproduces 98% of DCI-P3

This wide-gamut monitor faithfully reproduces almost the entire DCI-P3 standard used in digital cinema. It also covers 100% of the Rec. 709, EBU, and SMPTE-C standards and 99% of Adobe RGB. What's more, it reproduces the sky blues and lush greens that standard sRGB monitors cannot.




built-in sensorSelfCalibration Sensor for Hassle-Free Maintenance

Automate your calibration with the SelfCalibration sensor that is housed within the monitor's top bezel and swings down onto the screen only when calibrating. This sensor eliminates the need for a third-party calibration device and works with EIZO’s ColorNavigator 6 and ColorNavigator NX software.

True Blacks with 1500:1 Contrast Ratio

In compliance with the DCI standard, the contrast ratio is a high 1500:1. This produces true blacks that are otherwise difficult to display on a typical LCD monitor. Even when viewing the screen from an angle in a dimly-lit studio the dark tones retain their depth. Also, you can prioritize a high brightness and contrast ratio over the screen brightness uniformity by pressing a button on the front of the monitor.

Multiple Inputs

With a single cable, the DCI 4K resolution at 60 Hz is supported by both DisplayPort 1.2 inputs and at 30 Hz by both HDMI inputs.


IPS panelConsistent Color Display with IPS Panel

A large screen monitor often exhibits color shift when viewed from an angle. With an IPS panel, more than one person can view the screen at once with little change in color or contrast.


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, EIZO's patented digital uniformity equalizer (DUE) technology ensures a Delta-E difference of 3 or less across the screen when the monitor leaves the factory. DUE also counterbalances the influences that a fluctuating ambient temperature may have on color temperature and brightness to ensure stable image display.

10-Bit Simultaneous Display

With 10-bit simultaneous color display* from a 16-bit look-up table, the CG318-4K can show more than one billion colors simultaneously. This is 64 times as many colors as you get with 8-bit display which results in even smoother 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. Equipment that supports Deep Color is necessary with the HDMI inputs.


3d-lut.jpg3D LUT for Accurate Color Display

A 3D LUT is included which adjusts colors individually on an RGB cubic table. With the emulation function of ColorNavigator 6 and ColorNavigator NX, the 3D LUT applies a film look to the image so creators can check how it will be seen by their audience.



Stable Color in Just Three Minutes

A typical monitor takes 30 minutes or more for its brightness, chromaticity, and tone characteristics to stabilize. EIZO has shortened the warm-up time to a mere three minutes. Whether you are working in a studio or taking the monitor with you on location, you get reliable color display soon after turning the monitor on.

Individually Adjusted at the Factory

EIZO adjusts the RGB color characteristics of each monitor at its factory to eliminate variation and ensure smooth tonal display.

Save Thousands of Hours in Annual Maintenance

With ColorNavigator Network software, an administrator can centralize management of all CG318-4K and other ColorEdge monitors on a network. For example the administrator can self-calibrate, set color modes, register or edit asset management settings and other tasks whether the monitors are local or remote. This ensures that monitors always have the proper settings and saves hundreds or even thousands of hours in annual maintenance time.

color modesBroadcast and Cinema Presets

Preset modes for EBU, Rec. 709, SMPTE-C, and DCI ensure you can work in the appropriate color spaces and gamma values. To switch between the presets just push a button on the front of the monitor. With the built-in calibration sensor, you can adjust or maintain the brightness setting for each preset.






safe area makerSafe Area Marker

A safe area marker designates the area of the screen that will be displayed on any display device. This allows you to confirm that subtitles and other text will be visible.
Available with HDMI inputs only.

Flicker-Free for Reduced Eye Fatigue

The ColorEdge CG318-4K offers flicker-free viewing at all brightness levels. Now you can work without worrying about eye fatigue caused by viewing a flickering screen for long periods of time.

CG318-4K_l_hood.jpgShading Hood Included

To prevent ambient light from reflecting off the screen, a shading hood that surrounds the top and left and right sides is bundled with the monitor.
