EIZO Announces ColorEdge Prominence CG3145: 4096x2160, 98% P3 and HDR10

EIZO this week announced its new ColorEdge Prominence CG3145 reference monitor with a DCI-4K resolution and a display covering 98% of the DCI-P3 color space. The monitor is claimed to be designed for professionals working with HDR post-production, particularly for TV and home video industries. The display offers a very high brightness level and contrast ratio, but the key feature of the screen that EIZO mentions is the ability of its IPS panel to display both deep blacks and very bright colors at the same time without artefacts caused by the peculiarities of competing displays.
The EIZO ColorEdge Prominence CG3145 monitor is based on a 10-bit IPS panel that can reproduce 1.07 billion colors and features a 4096×2160 resolution at 60 Hz. The manufacturer says that the display has a 1000 nits typical brightness (as well as a 1,000,000 static contrast ratio). The ColorEdge Prominence CG3145 covers 98% of the DCI-P3, 99% of the Adobe RGB, as well as 80% of the Rec. 2020 color spaces (but these numbers may change as the product is being tuned up now). This comes with a 24-bit 3D LUT (look-up table) for HDR color gradations. As for connectivity, the display will have one DisplayPort capable of DCI-4K with 4:4:4 chroma subsampling at 50/60 Hz, as well as two HDMI 2.0 inputs capable of DCI-4K with 4:2:2 at 50/60 Hz. Since the monitor is aimed primarily at post production video professionals, EIZO has not currently disclosed support of sRGB and also does not disclose specs like response time or power consumption.
The key feature of the ColorEdge Prominence CG3145 display is its ability to properly reproduce both very bright and very dark areas on the scene without artefacts caused by local dimming (used on many IPS-based televisions and on some monitors) or an auto brightness limiter. EIZO does not reveal many details about the IPS panel it uses for the CG3145, but it claims that it has control of backlight intensity in every pixel. The latter means that the company either uses Panasonic’s IPS panels with a special layer of light-modulating cells that enable pixel-by-pixel control of backlight intensity, or a similar technology it has developed in-house.
In both cases, the pixel-by-pixel control of the backlight sets the ColorEdge Prominence CG3145 display apart from the rivals which use IPS panels with local dimming. Another feature that the monitor has is its 24-bit 3D LUT, which has a potential to produce more accurate colors than the 14-bit 3D LUTs supported by other HDR monitors. Speaking of HDR, it is noteworthy that the CG3145 supports both HLG (hybrid log-gamma) and PQ (perceptual quantization) gamma curves. The HLG is suitable for live TV broadcasting as it has a peak luminance of 1000 nits, whereas the PQ supports considerably higher luminance (up to 10,000 nits) and is suitable for recorded content. The combination of these features means that EIZO has positioned the ColorEdge Prominence CG3145 as a reference monitor for HDR content.

Given that the display is not going to show up for another six months, EIZO does not talk about its price. EIZO positions the CG3145 as a reference monitor, which are typically priced above professional-grade models.

What? Doesn't have G-Sync?Bah. *awaits abuse*

You had to wait too long. Why are you complaining about a feature for gamers being unavailable on a monitor for professional graphics work?Alexvrb - Saturday, April 22, 2017 - link
lmcd, your joke detector has a pending fault code. You might want to get that looked at.Azethoth - Saturday, April 22, 2017 - link
No the joke is on you. OP clearly asked for abuse and then got it.Anyway. As a prosumer I too am dismayed at the lack of combined G-Sync, Free Sync and OpenSync? or whatever the upcoming standard or alternatives are. Also, why no HDMI 2.1?

Points of interest to me here are that it may be using Panasonic's new LCD technology and that it doesn't have the capability to properly reproduce film and other movie refresh rates. Panasonic's new tech should bring LCDs much closer to OLEDs without the OLED deficiencies. But it's odd to me that it doesn't support more of the DCI-P3 and Rec. 2020 standards. You'd think that and the ability display 24Hz film would be more important for post production.Hopefully this is isn't going to turn out to be TOO expensive. I could see myself shelling out $5,600 for a CG318-4K but if this is going to run up to $10,000+ it's definitely a no-go.

For Colour grading, grading at 60hz is not a big deal because 98% of the time the monitor is displaying a still image. But that being said, don't quote me, but there's a good chance that it will support 48Hz. FSI is using the same panel for their HDR grading monitor to come out at the end of the year.Magichands8 - Sunday, April 23, 2017 - link
Interesting tidbit about Flanders using the same panel. I'll have to check it out. Thanks.Frenetic Pony - Friday, April 21, 2017 - link
Just look down the page to see a very similar spec Dell monitor for $2k, yes also calibrated and etc.I know Ezio has got the reputation for high quality panels, but with other similar spec monitors announced recently and more to (probably) come soon I don't see a HUGE range in price cropping up.

Reference monitors, especially cutting edge ones, easily go for $10,000+ unfortunately.Magichands8 - Sunday, April 23, 2017 - link
Yes, that's what I am afraid of, that it will be up in that range. I know Eizo for a long time has had at least one professional broadcast production model up in that range.
