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.

EIZO plans to demonstrate the ColorEdge Prominence CG3145 monitor at the NAB Show later this month. Actual sales of the product are going to start sometimes in late 2017 after the manufacturer finalizes all the details and specifications. 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.

If you need a reference monitor, why bother with an LCD?Just buy a 2017 LG OLED and be done with it. Those things can be calibrated to almost delta 0.
There is a reason Technicolor is ditching the 30,000 dollar Sony OLED reference monitors in favor of these new LG sets.

Not everyone wants a 55" monitor, nor the issues with OLED and image retention. The Eizo also gets 1000 nits of brightness where even the highest end 2017 LG OLED only managed 700 nits in testing (advertised as 1000nits).http://www.hdtvtest.co.uk/news/w7-e7-201703114438....

300 nits of extra brightness are a very poor trade off to the much higher dynamic range OLED brings to the table.700-800 nits is still 7 to 8 times brighter than what SDR content is graded to. And with proper tone mapping, the OLED will look better every time, even if the source is graded to 1000 nits.
Aside from the size argument (which to be honest shouldn't be a problem if you are grading video in HDR, it's actually a huge plus) I don't see why anyone would prefer an LCD for serious grading work.
Image retention is temporary, burn in is even more rare than in plasmas on OLED and really, those limitations pale in comparison to the problems LCD has:
-Terrible contrast (even VA panels can only muster 5000:1 CR)
-Turtle like response time (anywhere from 1ms on TN panels to 4-15 MS on other tech, compared to .01ms on OLED)
Basically, the choice is to pick a technology that was never a good enough technology in the first place (LCD) to something that can do reference picture quality.
Sadly, LCD will be with us for a very long time still, and while it has come a very long way since it's early days. It's still fundamentally flawed.

The panel listed in the article is 1,000,000:1 static contrast ratio. Everything else you said is wrong either ways dumb dumb.Kamus - Monday, April 24, 2017 - link
If you think everything I said is wrong. You're dumb.Gothmoth - Saturday, April 22, 2017 - link
you only read some PR but did not use your own brain before posting.. right?hahmed330 - Saturday, April 22, 2017 - link
Contrast: '1,000,000:1'Is it static contrast???
mobutu - Saturday, April 22, 2017 - link
Yes, it's static/typical and NOT dynamic:http://www.tftcentral.co.uk/news_archive/37.htm#ei...

Why link the panasonic tech?There is no indication than these monitors are using it. Which make EIZO's claims very dubious.
It's funny, because people keep bringing up this Panasonic tech (not you, but I've seen many others) whenever you mention how OLED is superior to LCD, as if the Panasonic tech was available everywhere at typical LCD prices.
But let's say it was available, sure. it would be better than what we have on current LCDs. But it doesn't do anything to improve response time, which is still well below OLED, and in the end affects things like input lag and motion smoothness.
WOLED sadly isn't coming to PC monitors at affordable prices any time soon since the TV market is nowhere near saturated from LG panels, but who knows. Maybe we'll see 40" OLEDs in the next two years.

"Why link the panasonic tech?"Well, it's very simple logic. If there is single supplier who has the technology ready, than it's most likely their's...
"But it doesn't do anything to improve response time"
Actually it can. Or at least the tech is able to significantly help with response time. Response time is measured from start of change to time when color reaches (and stays) within 5% of final value (or whatever margin you like). Now let's imagine the simplest case. You have white and you want to show black. Let's say, that normal LCD after 10ms reaches 10% brightness (from 100%). By that time 2-layer LCD is already on 1% of brightness (0.1*0.1*100). The other way around is even more counter-intuitive and it can increase response time. But you can drive much harder overdrive without overshooting much if you de-sync panels just right.
