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.

    The 16:10 variant would be 1600 px vertical, and 30 inch diagonal. It is quite understandable why anyone with a brain would prefer that. And there have been several such 30" monitors reaching similar price to this 27" so the OP is right about it being too much money, hopefully some nice discounts will appear for it though.

    People were using 1600x1200 15 years ago on 20 inch CRTs. Getting less vertical resolution now is really sad.

    If a 10" iPad can have better resolution, I don't see how you can think this one is OK.

    Ouch, still a retarded 16:9 product. When will a 16:10 27"-30" IPS monitor come out...
    I am still using the old dell 2709W. Not an IPS but i keep it because of 16:10.

    at least five years ago (Dell 3007); not sure if it was the first 2560x1600 monitor; but Dells model number scheme at the time baked in the year making it easy to date. Reply

    30" with 2560x1600 have been out for years, but they usually cost nearly twice as much as the 27" pendants. Vote with your pocket if you are serious, I am fine with 16:9 in this size range (though I go 16:10 below that). Reply

    Get over it already, 16:10 is gone. 16:9 has become the standard whether you like it or not, so you should start getting used to it. Move your Windows taskbar or OSX dock to the side, that gives you ~80px. If you absolutely MUST have vertical resolution, do what my buddy does: buy two smaller monitors and use them in portrait. Learn to adapt. Reply

    You are clueless. 16:10 is far from gone, in fact several companies have released new 1920x1200 screens in the last few months. 16:10 is also the standard in a 30" display.

    Apple is releasing a new notebook this year which will be 2880x1800, 16:10. Asus has at least one product coming out with a 10.1" 1920x1200 display.

    There are people all over the internet complaining about 16:9 monitors these days. You can't go to a hardware review site without seeing a growing numbers of people posting about how they think 16:9 is trash for a monitor.

    Right, but those hardware review sites (like here) are a representation of a very, very small slice of the monitor buying population. For that small slice, and professional designers and other people, there are still 16:10 panels being produced with their associated price premium. For most people, they're plenty happy with 16:9 panels and the more affordable price with them, and I really wish the comments didn't get filled with this endless diatribe every single monitor review.

    Just get a bigger 16x9. The argument is dumb IMO once you're at this high resolution. Reply

    If you're going to talk about affordable 27" 2560x1440 panels, you're missing the whole point: the Korean domestic market monitors: The Catleap/Shimian whatever other name monitor. Uses a 2560x1440 LG panel and can be had for ~$400 SHIPPED. Reply

    Sorry, just so I don't leave people hanging, yes these are real, no they are not a scam, yes sometimes they have a couple of dead pixels, but that's perfectly acceptable:
