Introduction

Almost 15 years ago I set up my first multiple monitor system, using a 17” and a 15” CRT. At that time it was a very uncommon setup, but now it seems that many people use multiple displays to manage their workspace. No matter how many displays you hook up, there are always some things that benefit from having a single, large, high resolution desktop, such as the spreadsheets that I use for doing display reviews.

27” and 30” displays with 2560 horizontal pixels have been available for a few years now, though the pricing on them has been very high that whole time. Sometimes you can find a display on sale and pick it up for a reasonable price, but typically the cost of entry seems to be right around $1,000 and up. Because of this people are still likely to buy two, or even three, 1920x1200 displays for the same price and run a multi-monitor desktop.

We finally have our first real affordable 27”, high resolution display on the market now, and it comes courtesy of HP. The HP ZR2740w is a 27” IPS panel with 2560x1440 resolution (16:9 aspect ratio) and an LED backlighting system. With a street price that comes in at $700 or below, what has HP done to be able to bring a high resolution display to the masses at a price well below other vendors? Thankfully, they provided me with a unit so I could evaluate it and see.

Design, OSD, and Viewing Angles

Since my usual desktop monitor is a lowly 20” Dell widescreen, unpacking and throwing the HP on my desk in its place was quite a difference. I was pleasantly surprised to see that the HP still has a stand with tilt, swivel, pivot, and height adjustments. When 24” monitors that are value priced, or even $300, are leaving these out it is quite nice to see on a value priced 27” display. The front of the display has four buttons: Power, Brightness +/-, and Source.

Once you look for the inputs to hook the display up you get your first clue as to how HP shaved the price on this display. The only inputs available are a Dual-Link DVI and a DisplayPort. For people that want to use their monitor for gaming or watching movies, there is no HDMI port available. With no HDMI port, there are also no speakers in the HP either. I was a little bit surprised that they still have the standard USB 2.0 hub with four ports available, as that seems like another item that could be cut to save a bit on costs, but I was happy to have it available.

Once you go to adjust the brightness, you’ll notice something about the OSD on the HP in that there isn’t one. There is no menu system either. The only adjustment available to the end user is a single brightness control that has no on screen setting. There is also no LUT inside of the monitor to help for correcting the color, but that wasn’t much of a surprise either. With no OSD, there are no color presets, no dynamic contrast or enhanced response modes, nothing beyond what you have as a standard. There is also no way to control the aspect ratio so if you feed the HP with a signal other than 2560x1440 you will have it scaled automatically and there is no way to adjust that. Because of this lack of an OSD, having the necessary hardware and software to perform your own calibration might be a little more important with the HP. In a sense, it's a bit of a throwback to the early 30" LCDs, except now there's a DisplayPort connection in addition to the DL-DVI.

Despite the loss of all these features, the HP does have the specs that many of us are looking for: 2560x1440 resolution and an IPS panel that is listed at supporting 10-bits per pixel with A-FRC (8-bit native), and has a native gamma of 2.2. It only has a standard gamut LED lighting system, so it is listed as being able to do 99.9% for the sRGB color gamut but only 77.2% of the Adobe RGB gamut. For many users, that's actually not a problem and could even be seen as a plus. (High gamut displays running sRGB content can sometimes look oversaturated if your applications aren't color space aware.) So now that we have an idea of what HP had to do in order to hit this price point, did the performance suffer from these choices? Here's a quick overview of the specs and then we'll get into the evaluation portion of the review.

Despite the large panel, viewing angles are very nice on the HP as you can see. To see much of a brightness shift you had to be very far off angle, and I had no issues at all with normal use.

    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. Reply

    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. Reply

    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. Reply

    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. Reply

    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 :) Reply
