HP DreamColor Displays Offer Unmatched Color Accuracy
HP announced two new HP DreamColor Displays, once again disrupting the color-critical display market by achieving new levels of affordability and color accuracy. The HP Z27x and Z24x displays for PCs and Macs feature HP's second-generation DreamColor Engine and provide up to 1.07 billion on-screen colors, achieving color error so small that it is not discernable to the human eye. Compared to the previous-generation product, the new displays include up to 60 percent more pixels, contain up to a 4,000 percent increase in the internal color palette and are up to 57 percent thinner.
The HP Z24x DreamColor Display delivers the color accuracy and consistency that has become synonymous with the HP DreamColor brand, at less than 25 percent of the price of the original HP DreamColor display. The HP Z27x DreamColor Display breaks new technology barriers by providing:
- Three times the color accuracy over the previous generation
- The first color-critical display featuring HP's hostless integrated calibration engine with built-in support for third-party professional color measurement instruments
- Ethernet-based remote management with an integrated web server that provides unprecedented control of the display
- A published software development kit (SDK) that allows customers to fully integrate the HP Z27x into their color workflows
- The most affordable color-critical display capable of 4K support
"The HP DreamColor Engine and our line of DreamColor products have become the gold standards for professionals who demand color accuracy," said Jun Kim, vice president and general manager, PC displays and accessories, HP. "This next generation of HP DreamColor Displays will once again disrupt color technology, providing customers with richer and more accurate colors than ever before."
The HP Z27x and HP Z24x DreamColor Displays are designed for professionals for whom accurate color management is essential, and consumers who seek to use only the best in technology innovations. Key features of the new displays include:
- Consistent 10-bit color accuracy from design to production with push-button color space selection and easy color calibration
- One-button access to presets including sRGB D65, sRGB D50, Adobe RGB, BT.709, BT.2020 and DCI-P3
- Ability to easily create a custom color space with full control over primaries, white point and tone response
- Easy connection to existing workflows through support by Windows, Mac or Linux operating systems
The HP Z27x DreamColor Display also offers:
- An ultrawide Digital Cinema color gamut with 100 percent of sRGB, 100 percent of AdobeRGB and 99 percent of DCI-P3
- The HP Night Vision interface with auto-fade button backlights and selectable red button backlight color for better low-light viewing in darkened working conditions
The result of an unprecedented technology collaboration with DreamWorks Animation SKG Inc. and other leading studios, the first HP DreamColor Display, the HP LP2480zx, addressed an increasingly critical need for affordable and consistent color accuracy in the animation, photography, film/video post, broadcast, product design and graphic arts categories.
"HP technology has enabled our studio to deliver amazing visual effects to our audiences," says Kate Swanborg, Head of Technology Communications and Strategic Alliance, DreamWorks Animation. "The new Z27x raises the bar in accuracy and ease of use for ensuring perfect color consistency from scene to scene and empowering further creativity in our artists."
With the new DreamColor Displays, HP has once again pushed the limits of innovation to bring users unrivaled accurate and consistent color from displays, to the big screen to print. Each new feature is a result of direct feedback from key advisory council members and customers looking for new ways to transform the way they work.
"The new DreamColor Z Displays are amazing and will be a game changer for many photographers," said Chris McLennan, an international, award-winning adventure and travel photographer and Nikon Ambassador. "The price point will mean that everyone who is into photography -- whether a full time pro or a keen enthusiast -- should be looking into this product."
Pricing and availability
The HP DreamColor Z27x and Z24x are available today for $1,499 and $599, respectively.

I have never heard of, or used, 6-bit + FRC IPS monitors. I can tell dithering is used with relative ease. It's not used on any IPS monitor I have seen.
Sure.

It's more common than you think. In the recent past anything called an 8 bit IPS that didn't cost a fortune was actually a 6 bit + FRC e-IPS. My last monitor was a U2312 and that was also a 6 bit + FRC e-IPS. The dithering is not so easy to detect as you may think. Despite the hyper-grain coating which drove me insane, it was clearly better quality than any TN or VA panel.
From what I read a lot of TN panels were 4 bit + FRC + whatever other tricks they could come up with to mask their poor colour reproduction.
Speaking of poor quality panels, I'm using my laptop at a coffee shop right now and the screen drives me nuts. I can't get a clear view from any angle, this is a $1000 Toshiba with discrete graphics, you'd think they would use something better than a $20 TN for a screen, jeeze. (No I did not choose the laptop, it was a gift.)

Mmm yeah true forgot about e-IPS. I took a look at a couple of e-IPS screens and yes, while I didn't really look for dithering I didn't notice it on my own either. However, for S-IPS, AH-IPS, PLS, etc... they're all 8-bit. I think the "e" stands for economy, so it's understandable. NEC started this with their EA231WMi back then a few years ago.
That's why I picked the Lenovo Ideapad Yoga 2 Pro. It has a 3200x1800 Samsung RG-BG PPS display. Beautiful color reproduction, although it comes with a green error out of the box (corrected with colorimeter). It's glossy (reflective) therefore it's very clear and crisp, but its contrast ratio turned out somewhat low at 400:1.

Well if any of you are artists looking for colour accurate panels stay away from the Dell 2713H series. Sure it costs less, $1000 in the US, but it's not worth the problems.
They're 10 bit but it seems the yellow phosphor used on it along with GB-LED backlighting (to achieve that more "neutral white" and what I assume to be their trick behind making it "10 bit") causes major problems. The colours are completely inconsistent and even if you get a consistent one this monitor can actually get permanent burn in.
I actually have one sitting here in the box to exchange. They develop problems over time, such as the colours becoming less uniform over time.
Thanks for the warning. Actually I own and use 2713H and it works great for me. However I only use 8-bit color. I hope it won't get corrupted anytime soon, but I'm aware that me hoping it won't make it work great in a long run if I'm unlucky. My other computer has HP LP2475W, and while it was good in general, it had noticeable lag, and over time, the panel light distribution got distorted. Perhaps if I find someone to fix my good old EIZO T965, I might use it for gaming again.
If I was going to do something more serious, I'd rather go for these HP's, or if I had greater budget, I might buy some premium brand.
