A Review of the Eizo ColorEdge CG318-4K Monitor
The Eizo ColorEdge monitor is one powerhouse of a 4K monitor that delivers some very ideal combinations of specs for a range of different professional users. For the artistic digital editing crowd that wants to tweak with VFX and CGI, the ColorEdge delivers some of the best visual specs there are on the market right now and for the broadcast/video production user, this monitor offers excellent connectivity, a wonderfully large 31.1 inch screen and a true 4K resolution of 4096 x 2160 pixels, instead of the much more common 3840 x 2160 pixel 4K ultra HD we normally see in cheaper models.
Other technologies like a built-in color sensor, enhanced pixel density and self-adjusting display settings create a deeply advanced piece of professional editing and pro 4K workflow technology that would be a powerful addition to any studio setting or visual editing office.
The good features of the Eizo ColorEdge start right at its display resolution. The 4096 x 2160 pixels of the CG318-4K’s 31.1 inch screen create a very fleshed out pixel density and, more importantly, deliver a resolution that perfectly matches the one most often used for 4K film making. The value of this is obvious: this monitor is perfectly fitted for monitoring and editing the workflow associated with ultra HD movie and video production footage and offers a screen that lets you fit the entire content of a piece of newly shot content onto the display all at once. The ColorEdge is particularly useful as a reference display because of this tue 4K resolution alone.
On top of this, the CG318-4K also offers some of the best color accuracy of any 4K monitor on sale today. Truly, this machine delivers a color output and realism that is perfect for even the best types of professional visual editing work. Outputs on the sRGB spectrum in the ColorEdge easily run to 100% and even the broader, more difficult to match AdobeRGB spectrum gets fulfilled to an accuracy of 99%.
Eizo even claims that the CG318-4K can manage a remarkable 98% of the DCI-P3 color space, which is the latest of its kind and commonly used during digital cinema editing and post-production workflows.
Finally, the CG318-4K offers a self-adjusting color sensor that always ensures the monitor is delivering ideal settings for whatever work you’re doing. This involves adjusting various aspects of the display at select intervals.

The Eizo ColorEdge is no normal 4K monitor and its list of specs practically reads like a wish-list of ideal pro design and video monitor characteristics. That said though, nothing is perfect and there are two relatively modest deficiencies with this particular model.
First of all, the ColorEdge CG318-4K is bloody expensive. This is definitely not the kind of monitor a casual amateur is likely to grab. With a price tag that sits at just below $6,000, the CG318-4K costs more than many extremely high-end 4K TVs on the market. Thus, if you’re buying this particular screen, it’s because you’re very serious about having some of the best visual editing features available today for a professional context.
Second, and this truly is disappointing when you consider everything else at work in the CG318-4K, the ColorEdge doesn’t come with an HDMI 2.0 port. It certainly offers two DisplayPort 1.2 connections for data transfers between PC and screen at 60Hz, but HDMI 2.0 would offer the same 60Hz in a much more flexible way. Why Eizo couldn’t bother to include 2.0 when even $600 dollar 4K monitors from Acer or $900 monitors from Viewsonic now include it is a bit of a let-down.
Finally, the IPS screen might also cause minor problems for video editors who are working with high-speed action sequences or gaming related projects. IPS is known for its slow response time and the ColorEdge delivers particularly poorly in this regard with a grey-to-grey response time of 9 milliseconds.
The Eizo ColorEdge CG318-4K 4K monitor is just about the best kind of 4K visual editing and video broadcast workflow screen you can get your hands on. If you can stomach the high price tag this baby comes with, you’ll be getting your hands on a level of quality which simply will not disappoint in almost any professional setting.

The major highlights of the Eizo ColorEdge CG318-4K are its sheer visual accuracy delivery, its self-adjusting color calibration and its very robust package of connectivity features.
As we had said, this monitor delivers some of the most full bodied and realistic color gamut range available today in any 4K UHD display of any type. In the ColorEdge, this means perfect sRGB spectrum delivery, 99% AdobeRGB delivery and even 98% DPI-P3 digital cinema color delivery. This last spec is very rare in a 4K monitor and most models on sale today don’t even list it as something they can deliver on at all, let alone to such a high percentage.
Furthermore, the ColorEdge gives you an excellent, rich contrast ratio of 1500:1. Most 4K monitors, even some fairly expensive professional models don’t manage to do even half of this or barely touch upon 1000:1 contrast levels. The ColorEdge sails past all of that to maximize both brightness and dark tones for exquisite dynamic range in a 4K PC display.
In addition to all of their built-in specs, Eizo’s CG318-4K monitors also come with some fairly robust software. This includes the manufacturers ColorNavigator Network software for centralized administration of ColorEge monitors tied to a single network within an enterprise infrastructure. Furthermore, the matching ColorNavigator color management software that comes with this monitor makes accessing and activating or deactivating specific color features or turning on and off the built-in calibration modes into a very simple task.
What’s also interesting is that Eizo has finally started coming around to touch-sensitive virtual button instead of their physical counterparts. This has previously been something the company studiously avoided in its monitors, but in the ColorEdge, features such as backlighting and various menu options are activated via touch controls.
Finally, there is the interesting simplicity of preset Broadcast and Cinema settings. Basically, preset modes exist for EBU, Rec. 709, SMPTE-C and DCI, making working in any of these color spaces and gamma values as simple as touching a button on the screen. Furthermore, the built-in calibration sensor we mentioned above lets you adjust brightness for each of these presets.
The CG318-4K’s True 4K screen resolution of 4096 x 2160 pixels is a definite primary benefit of this particular 4K screen. While some users might not at all care about the difference of a few hundred thousand extra pixels between 4096 x 2160 4K and 3840 X 2160 pixel 4K ultra HD, the usefulness of those extra pixels is doubtless when it comes to using Photoshop, Illustrator, InDesign or DaVinci Resolve. The larger 4K grade simply offers more working room and a much more complete picture when working with pro studio 4K video footage in particular, since it’s usually shot in the same true 4K resolution. The very large 31.1 inch screen is still another bonus in this work-space regard.
As for the visual specs surrounding color accuracy, and contrast, they are exquisite, as we’d already described. Seriously, the color specs of the ColorEdge CG318-4K simply leave almost any other 4K monitor in the dust when it comes to actually working with that you get here.
In terms of both sheer color range and accuracy of color reproduction, the CG318-4K performs at within a hair’s breadth of being perfect. Testing has shown that 100% of the sRGB spectrum gets reproduced, while 99% of the Adobe RGB gamut range also appears. This latter spectrum is much harder to match and most monitors don’t reach even 90% of it. Then there is the even more advanced DCI-P3 spectrum, and even with this digital cinema color gamut, the ColorEdge manages 98%, at least according to Eizo. That’s great news for video editors and those working with cartoon or PC game design.
Furthermore, reproducing so many colors isn’t the only thing in which the ColorEdge excels. It also reproduces those colors with excellent accuracy. This level of accuracy is measured by what is called Delta E, with a larger number signifying greater inaccuracy of color reproduction. In the case of the CG318-4K, overall average Delta E sits at a miniscule 0.60 to 1 range. This is pretty much as good as it gets for realistic color reproduction in a 4K display.
The built-in calibration tool that emerges from the side of the monitor body for manual or automatic self-calibration of the screen is not just a very neat looking gimmick, it also does a superb job of accurately and usefully modifying the screen’s outputs so that they perfectly match what’s coming out of your PC graphics card.
The Eizo ColorEdge CG318-4K offers the standard package of essential connectivity ports with just a single moderate deficiency which is all the more surprising given this PC display’s overall quality.
Thus, what you get with the CG318-4K is two DisplayPort 1.2 ports for showing 4K resolution at a full 60Hz of smoothness, straight from your PC’s GPU. Since most graphics cards on sale today come with DisplayPort 1.2, getting the PC to mesh with this monitor at 60Hz shouldn’t be a problem.
Then there is a single USB port on the monitor itself and an additional small hub of three other USB 3.0 ports included with the ColorEdge.
Finally, the CG318-4K also comes with two HDMI 1.4 ports. While these are great for certain third party media device connectivity uses, they’re also slightly disappointing since they aren’t the newer, 60Hz capable HDMI 2.0 ports that are now appearing even in some far cheaper 4K monitor models.
The Eizo ColorEdge CG318-4K is definitely not a low priced 4K monitor. This machine is built for professional users in mind and its price reflects this level of quality. It’s currently retailing for $5,979 on U.S websites and for 4,034.03 GBP (British Pounds) on Amazon.co.uk, where it is mainly available in stock.

To summarize very briefly, the ColorEdge CG318-4K is a superb monitor with virtually no defects and some of the best color reproduction in existence today in a 4K monitor. However, the ips panel display technology results in a very slow grey-to-grey response time of just 9 milliseconds and the lack of HDMI 2.0 ports is a bit of a disappointment for such an advanced piece ot display technology.
