Dell UltraSharp U2711: Quality has a Price

Dell U2711 - Near Professional Quality at a Pro-Am Price
If you're a professional image or video editor, it's possible that the U2711 will fall a bit short. Specifically, we've seen better color accuracy, especially after calibration. For the price, we'd recommend looking at HP's LP3065, or one of the other 30" S-IPS displays. However, the U2711 does win out in quite a few areas. If you want a fine dot pitch, there's no better desktop LCD right now. The U2711 also supports 30-bit deep color with 12-bit internal processing; most displays with 30-bit color output cost twice as much! Look at the HP DreamColor LP2480zx for example: $1800 online and it's a 24" 1920x1200 LCD. (Note that we haven't tested that particular LCD; for the price we would hope color accuracy is better than the U2711, but we can't say for sure.)
Since the U2711 uses an IPS panel, viewing angles are a non-issue. Off-angle viewing isn't perfect, but it's far better than what you get from any TN panel and as good as any LCD on the market. Color quality and accuracy on IPS panels are also very good, and given the various compromises you can make we feel IPS is the best overall solution for LCDs right now. Very likely we won't get anything better until OLEDs, SEDs, or some other display technology takes over, and right now the cost of larger OLED solutions is prohibitively high.
Another great feature on the U2711 is the large number of video input options. HDMI, DisplayPort, and two dual-link DVI connections will be the preferred method of connecting, but you can also use VGA, component, or composite video. The ability to handle lower resolutions very well is a definite plus, though with a decent GPU you can often let the graphics chip do the scaling and not worry about shortcomings in the LCD's scaler. The problem with LCD scalers is that they also add a bit of latency. We don't know how much, but we do know that the U2711 has about 15ms more latency than other IPS displays that we've tested in the past. The latency may also come from the 12-bit internal color processing, but that would be part of the scaling hardware. Having seven different video inputs is going to be overkill for just about every potential user, but we could certainly see situations where using two or three of the inputs is feasible, e.g. PC, HDTV, and gaming console. The U2711 supports an optional audio bar along with audio out, but in either case you'll be limited to 2-channel audio, so you might want to look somewhere else for an ideal home theater display.
Aspiring imaging or video professional looking for a capable display will find the U2711 is a great option. We've seen better color accuracy, true, but few displays offer out-of-box colors that are anywhere close to this good. Dell guarantees every U2711 will have a Delta E of less than 5.0 without any extra calibration, and our test unit delivered an extremely good result of 2.24 (average Delta E). Buying a separate colorimeter and software will set you back another $200-$300, though you could then use just about any IPS or PVA LCD. The U2711 also delivered very good color uniformity. I still like the larger 30" LCDs, but then I have access to a colorimeter, I only need one video input, and I prefer a larger dot pitch.
We suspect "true" professionals will still prefer more expensive solutions that can achieve a Delta E of less than 2.0 for every color patch, but that's a very small market. If you're wondering if you might notice the colors where the U2711 "only" scores ~4.0, then you likely don't need to worry about it. In fact, we think most professionals would only "see" the problem if they had access to a colorimeter; you really won't notice any problems with the uncalibrated results using your naked eye.
Bottom line is that if you're looking for a large LCD with lots of features, a high resolution, great colors, and what we feel is the best current LCD panel technology, the Dell U2711 should be at the top of your list. $1050 isn't chump change by any stretch of the imagination, but you won't find quality like this in a sub-$500 LCD. In fact, the only real competition right now comes from the 30" S-IPS panels that have been around for several years. If you want something a little smaller, or if you have a need for 30-bit color support, the U2711 is a better buy than anything else currently on the market. This is a great high resolution display that delivers on the quality and features fronts, and we're pleased to award the Dell U2711 our Gold Editors' Choice award.

Where is the application form for writers/reviewers? I'm interestedJarredWalton - Friday, January 22, 2010 - link
It was posted by Anand a few weeks back... here's the link; I don't know if he's still sorting through and accepting submissions, but it can't hurt to try. :)http://www.anandtech.com/showdoc.aspx?i=3698">http://www.anandtech.com/showdoc.aspx?i=3698

16x9? Boo!Mr Perfect - Friday, January 22, 2010 - link
Oh, hey, you're right.Why did Dell make this thing a 16:9? On what planet in this or any parallel universe is a 2560x1440 display more desirable then a 2560x1600 one? I can almost understand why they make 16:9 24" screens(Look it's 1080! Full HD! It must be the bestest resolution available!), but that doesn't apply here. Give us back the other 160 vertical pixels, please!

Agreed. its a matter of marketing bullshit. 16:10 is going the way of the Dodo just because marketing monkeys like to yip-yap about "FULL HD" resolution despite inferiority in every way - its a sad, sad world.But its probably not Dell at fault there, but the panel maker(s) instead. You cant sell what you cant buy as a company like Dell.

I totally agree, and I hate 16:9.strikeback03 - Friday, January 22, 2010 - link
I'm gonna guess Apple was the one that paid some LCD maker to make a 2560x1440 panel, so Dell was stuck with that. Can't be a lot of options for these panels.Ph0b0s - Friday, January 22, 2010 - link
You need to explain in your reviews of high gamut displays the implications of getting one of thoes displays. Especially to your gaming audience.High gamut displays are not always a good thing. They are great for photo and video profesionals who use applictions that have color management (can covert to the high gamut color space). But for every other application and game where the assumption is that the display connected is a normal gamut one, the colors will be over exagerated or just wrong. The reds and greens will sear your eyes out. Now this my be ok with the other advantages of the monitor (small dot pitch, etc), but people should be given the negatives as well as the positives.
Hopefully all apps will become color managed at somepoint and this will no longer be an issue, but until then high gamut displays are bleeding edge. I expected better from anandtech.

Agree, it should be mentioned. Technically - aside from OS and software problems - more is better. But unfortunately I don't know of any video players that are color managed even on Windows 7. Same for games I guess. This can be fixed at the OS level but I don't think Windows 7 does that with all applications.Presumably there is a monitor setting for sRGB so if you are using non-color-managed software you can switch to it temporarily.

A lot of Wide gamut displays have an sRGB emulation mode. But a lot of them are rubbish and don't realy do a good emulation. Seems to depend on whether hardware (lut ?) has been installed in the monitor or not. Maybe this should be part of the testing during the review to see if the sRGB emulation is any good or not. Since it is an expensive display reviewd above, then maybe the sRGB emulation is being done properly on this display....
