HP ZR2740w - High Resolution IPS that Doesn't Break the Bank
by Chris Heinonen on March 16, 2012 1:15 AM ESTColor Uniformity and Color Gamut
The calibrated results on the ZR2740w were pretty good, but with such a large panel was the uniformity going to suffer because of it? 23” 1080p displays have a hard time with uniformity and are easier to fix, but perhaps since the HP is a higher end display more work has been put into keeping the screen uniform all around. Measuring nine points around the screen at the 200 nits calibrated setting, you can see what we found.
Only one of the nine locations had an average dE above 3, and the median value there was still below 2.75. What concerned me the most is that the uniformity on the grayscale was so bad, so when you have a solid white background, which is likely on a monitor like this with spreadsheets and other applications, you will be able to clearly see a shift in the white point as you look at it. Colors were far more consistent than white was across the display, so it seems to be a shift when the panel is fully driven, probably due to unevenness in the lighting I would assume.
While it has an 8-bit panel and can do 10-bit colors with A-FRC, the backlight system of the HP means that you aren’t going to get the full AdobeRGB colorspace on it. The HP comes out of Gamutvision with 76.82% of the AdobeRGB space, pretty much dead on to the 77.2% in the specs.

I agree bro,$300 was alot for me when I was 12 too.

I am 25, employed in IT and $300 is still a lot of money. Don't be a snob. $700 is hard to justify for a monitor if you're not in a profession that demands color accuracy.Snowshredder102 - Friday, March 16, 2012 - link
The prices are certainly steep; however, my mindset on this is if I'm going to stare at the damn thing for 8+ hours a day it better look nice.cheinonen - Friday, March 16, 2012 - link
It also depends on what you are working on. If I'm dealing with massive Excel spreadsheets all day, for example, being able to see everything on screen at once, at a reasonable size, might mean that I cut out 10-15 minutes a day of scrolling back and forth to see my data. Add that up over a year or two, and it can be quite easy to justify the price of a high resolution monitor over even a pair of lower resolution ones.I don't own a 27" monitor at this time, I usually use a 20" in portrait mode and a 24" CRT that sit on my desk, but I have to say that after having a 27" monitor around for a while, it did help with productivity and I would love to keep one around. Figuring out if its worth the cost is up to you, though I wouldn't say its limited to color accuracy at all. People that needs lots of space - working with Excel, programming, anything really could benefit.

There is a lot more to these kind of monitors than color accuracy. My big problem with non-IPS panels are the limited viewing angles. Unless I hold my head in just the right spot, readability goes out the window. It's possible to make TN monitors with wide viewing angles, but hardly anyone does it.You can find some 24" IPS monitors for #300-400 these days, and they're well worth it to me. I have the HP zr24W at home (the 24" version of this monitor's previous generation). It's one of the best computer equipment purchases I've ever made. One of the things you use 100% of the time on your computer is your screen. Don't skimp on this! You may not need a 27" monitor, but the 24" version of this is much more affordable, and still worth it.

I stare at a computer screen all day every day for work. For my job as a programmer there is simply no way I could justify the 2-3x purchase price of IPS panel displays over TN. I fail to see how viewing angles matters at all since I am sitting directly in front of my screens, not more than 60 degrees off center.I hate having a crappy TN panel on my laptop, but for my desktop, two Asus's like these get the job just fine for under $170 each: http://www.newegg.com/Product/Product.aspx?Item=N8... .

It's your choice: drive a car that costs $400 less and get a quality monitor, or drive that +$400 premium car. The monitor might last you 10,000hr, which is a 4 cent/hr premium. That's easily worth it to me.whitehat2k9 - Friday, March 16, 2012 - link
I guess you and I have different definitions of "breaking the bank."colonelclaw - Friday, March 16, 2012 - link
I don't know anything about this HP, but with regards to your suggestion about using 2 Dell U2412Ms I can definitely give that idea the thumbs up. Having read your recent review of the Dell I bought 4 for my office. Now that they have been all calibrated I can say that they are spectacular, and for what I do (3D artist) working on 2 monitors is preferable to one single large one.Adul - Friday, March 16, 2012 - link
I have 2 of the ZR24w monitors on my desk now and my GF had to out do me and got two of these HP Z2740w on her desk. I love both monitors and both look great. I am going to have to borrow hers for some gaming this weekend :)
