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.

    Why exactly wouldn't this be able to refresh at 24Hz? Just because the spec sheet says "Refresh rate: 60Hz" doesn't mean it can't go lower than that - in fact, it would be very, very odd if it couldn't. Just because it doesn't have any kind of adaptive refresh rate (which isn't in use in any professional application AFAIK) doesn't mean it can only run at a single refresh rate ... Reply

    Well, it's particularly possible with Eizo involved that it WILL be able to reproduce film rates properly but if they are going to implement that and report 60Hz as a specification I would expect them to mention that capability as well. Usually 24Hz is problematic for LCDs and higher refresh rate multiples are more common which clearly is not an option with this monitor being that we already know it's capped at 60Hz. Although Eizo already has proper implementation of the lower rates in some of their other high-end CG models so there is still hope.

    If they do it then it will be very interesting to see if they enable it for 10+ bit output at the relevant rates seeing as how they are going to be covering a significant portion of Rec. 2020 and HDR.

    At this point they should ignore rec.2020 and compare it to rec.2100.

    I'm very impatient for these products to reach the wider market.

    Rec2100 is just rec2020 and SMPTE ST-2084 combined, which is what this monitor does. Reply

    Funny! I had come back to update my comment when i looked over rec.2100 again and saw that it can use 10 OR 12 bit quantization.
    Anyway, yeah, hdr10 is pretty similar to rec.2100 save the support for hlg oetf and 12 bit depth.
    Otoh, now we have hdr10+, which is pretty much identical to Dolby vision except for the lower bit depth (such may be less important given the per frame, metadata driven nature of hdr10+).

    I stopped giving a crap at 60Hz which means they are using DP 1.2. Wake me when the DP 1.4 monitors at 120/240Hz arrive with HDR and 10Bit DCI-P3 100%. Reply

    That's a joke, right? Reply

    Just buy two monitors then. One for your work/hobby and one for gaming. Reply

    I hope to one day have enough money to buy a monitor like this just for hell of it. Reply
