We haven't had a display review since our desperately seeking quality LCDs article. That doesn't mean there haven't been interesting displays released during that timeframe, but the trends highlighted in that last article have continued. TN panels are everywhere and are by far the cheapest option, although they do have a bit of competition from E-IPS displays. For example, we have 1080p 23" TN LCDs starting at under $200, compared with 1080p 23" E-IPS LCDs for $300. However, E-IPS isn't the highest quality implementation of IPS (in-plane switching) LCD technology; what if you want to go for the real deal?

Despite the preponderance of TN panels, it's still possible to find some good quality IPS displays. The catch is that you need to be prepared to spend two or three times as much money (or more!) to get that quality. Most consumers will look at the 24" TN panels starting at $200 and then they'll look at an IPS or PVA display costing $550 or more and they'll wonder why anyone would spend the extra money. The answer, quite simply, is quality. Dell offers U-series UltraSharp displays that look to satisfy professional users without quite getting into the professional display price range, and they'll provide substantially better quality than any entry-level display. That brings us to today's review.

The latest offering in the U-series is the U2711, a 27" beauty sporting extremely impressive features. For starters, it has an IPS panel, but this isn't your granddad's IPS panel. The U2711 has an extremely high resolution 2560x1440 panel - similar to the panel that's used in the Apple 27" iMac. Notice that we highlighted the word similar? That's because the two panels aren't identical; the glass might be the same, but there are definitely differences.

For one, Apple uses LED backlighting whereas the U2711 sticks with CCFL technology. But isn't CCFL worse? That depends on what you're after; the iMac 27 offers a 72% color gamut while the U2711 has a 102% color gamut (based on the CIE 1931 standard). Using RGB LEDs, it would be possible to get a similarly high color gamut, but our experience with RGB LEDs to date is that they cost more and consume more power than regular LEDs, so we can understand Dell's interest in sticking with the "older" technology. (We've only seen RGB LEDs in a few laptops so far, and as one example it's a $175 upgrade on the Dell Studio XPS 16 compared to a regular white LED display.)

Since this is a display rather than an all-in-one computer, there are plenty of other differences between the Apple and Dell LCDs. Dell includes just about every input you might want on the back of the LCD - DisplayPort, HDMI, two dual-link DVI connections (all with HDCP support, naturally); and just for good measure they toss in VGA, component, and composite video connections as well - not that we would recommend using those if you can avoid it, though the VGA connection is always good to have "just in case". Like most UltraSharp displays, you also get a couple USB ports on the back, two more on the side, and a handy flash memory reader.

Besides having a higher color gamut and different backlighting technology, Dell uses 12-bit internal color processing with the ability to output 10-bit color. That means you can get 1024 levels of grey instead of just 256, reducing the amount of banding present in certain situations. 24-bit vs. 30-bit color also means you get a color palette of 1.07 billion instead of 16.7 million, though we were unable confirm this in testing. First, you need to have a graphics card with the ability to output 30-bit color, which typically means you need a workstation class GPU. You also need some sort of "special sauce" - specifically, you need an application that knows about deep color support. We connected the U2711 to a Dell Precision M6500 notebook (Quadro FX 3800M GPU) via DisplayPort. NVIDIA tells us that the GPU is aware of the deep color capability of the display at that point, but it requires an appropriate application before 30-bit color output would start. Despite our inability to test this feature, considering the cost of other 30-bit displays (often they are priced upwards of $1800), the U2711 becomes a very interesting option for users that need (and know how to use) "deep color" support.

So what's not to like? As with so many other things in life, all of these lovely features don't come free. The U2711 has an MSRP of $1050, so it costs quite a bit more than lesser 27" displays. Then again, it has a higher resolution, better features, and it's still $200 cheaper than most 30" LCDs. Overall, the U2711 makes a very good impression if you're after a high quality LCD; it's just not intended for users that are merely looking for a decent display at an affordable price. If you're a discerning image professional or just someone fed up with lackluster consumer LCDs, read on to find out if the U2711 is the right display for you.

    Where is the application form for writers/reviewers? I'm interested Reply

    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. :)

    16x9? Boo! Reply
  • 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. Reply

    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. Reply

    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.
  • CSMR - Friday, January 22, 2010 - link

    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.
  • Ph0b0s - Friday, January 29, 2010 - link

    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.... Reply
