Dell UltraSharp U2711: Quality has a Price

Resolution Support and OSD
While the ideal solution is to run your LCD at the native resolution, there are times when you might want to use something lower. With the fine 0.233mm dot pitch and 2560x1440 native resolution, running at something lower becomes even more likely. We tested the VGA, HDMI, DisplayPort, and DVI connections to see how the U2711 would handle non-native resolutions (note that we didn't test component or composite video). The OSD provides three aspect ratio options: Fill (use the entire LCD, with stretching), Aspect (fill as much of the LCD as possible but avoid stretching), or 1:1 (no stretching at all).
The vast majority of resolutions work exactly as you would expect. 800x600, 1024x768, 1280x800, 1280x960, 1280x1024, 1440x900, 1600x1200, 1680x1050, 1920x1200, and 2560x1440 showed no problems at all. Also, when using a VGA connection, every resolution we tried worked properly. Shift to the digital connections and we did encounter a few minor issues.
Starting with DVI, both 720p and 1080p filled the whole LCD regardless of the aspect ratio setting. This isn't terrible, since the image will still maintain the correct aspect ratio, but it does mean that the 1:1 setting failed to work in this instance. We also encountered some oddities with 720p and 1080p using an HDMI cable at times, but those problems appear to be more of a laptop driver issue than something in the U2711. On one laptop, 720p output always looked blurry, and the 1:1 setting didn't actually map to 1280x720 pixels as far as we could tell. In general, though, these common widescreen resolutions still worked well.
The resolutions where we had the most problems are all less common resolutions. On DVI, 1280x768 didn't have the correct aspect ratio, with black bars on all sides. 1360x768 stretched horizontally but not vertically on "Fill", making for a very skewed result, "Aspect" left borders on all four sides, but "1:1" worked properly. 1792x1344, 1800x1440, 1856x1392, and 1920x1440 all did an "aspect" stretch, regardless of OSD setting.
HDMI didn't show as many resolutions, probably because we had to use a different computer as the source (a laptop). Again, "odd" resolutions caused some incorrect behavior, but we don't really fault Dell. 1152x648 and 1776x1000 (underscanned 720p and 1080p, respectively) have a black border at all times, and like the DVI connection 1360x768 was squashed vertically unless you use the "1:1" setting. DisplayPort behavior was the same as HDMI. Note also that the HDMI connection didn't allow us to select resolutions above 2048x1152 (a 16:9 resolution). 2048x1152 was also the maximum resolution we could use on a VGA connection. We're not sure if the limitation was with our test laptop or if it's inherent with the U2711, as we don't have any HDMI connections that we're sure will properly handle 2560x1440.
In general, all but a few uncommon resolutions worked well. Something else we really liked was the "Sharpness" setting when we were using something other than the native resolution. The default setting of "50" appears to pass the signal on without molesting it, but as you move towards 0 the display becomes a bit blurrier and increasing towards 100 will apply a mild to moderate sharpening filter. Running at 1680x1050 with sharpness set at 70, you have to look very closely to notice that the LCD isn't running at its native resolution. Other LCDs have a similar feature, but on many displays the sharpness setting is only active if you use an analog connection (i.e. VGA).
The OSD
For the sake of completeness, here's a gallery of all the OSD settings. Yes, there are a ton of options. We like that Dell allows you to customize the "quick jump" buttons, but we wish they had allowed us to make one of the settings "Aspect Ratio" rather than limiting the choices to "Preset Modes", "Brightness/Contrast", "Input Source", or "Mode". There's really not much to say about the OSD: it works as expected.

Honestly, I'm sitting in from of my 3007WFP (not the HC version) and moving my head around and I just can't see anything. LOL.I'm looking at a white background and I can't see anything bothersome. I just did the same thing with a couple glossy laptops as well as the U2711 and I'm still not seeing anything sparkly. In fact, I just wandered around my lab and looked at six different LCDs (laptop and desktop, glossy and matte) and I'm still at a loss.
I might actually sort of see what you're referring to, but even then it just doesn't register as something distracting to my brain/eyes. My best guess is that either my eyes just aren't good enough to see it well (entirely possible), or my brain has adapted to where this effect doesn't affect me.
This is something I try to get across in my display reviews: you know what bothers you and I know what bothers me, and sometimes something that I totally don't see will irritate the hell out of others. If you can see/test a display in person, that's your best bet obviously. I figure if you're spending $1000 on a display, you'll want to do everything you can to make sure it's the right panel for you in advance of laying out the cash.
Caveat emptor, eh?

Not really. Most of the issues people are referring to and talking about are what I like to call "subjective preferences." People want things the way they like them to be will pay more attention to the features, defects, etc. For most users, they aren't even aware of most of this features/defects to even begin realizing and thus not seeing.Selecting a TV is no different. However, once you do start to pay attention to what others are saying then you will begin to notice as it becomes more apparent.
If you can't see and anomalies on your 30" I wouldn't worry about it or bother to do research. Doing so might just ruin your enjoyment of it. For those that care way way too much, they usually end up here...

You don't need to mvoe your head around to see it. I can get the same sort of thing only less severe on my LP2475W but only if I'm less than one foot away which is not normal use. With Dells I see it very easily from normal distance (2-3 feet.)If Dell still has a solid 100% back free shipping return policy on monitors there's little risk in trying them. All I know is when I tried a 2407WFP a few years back even without reference to another LCD I was like 'wtf is this?' and then found comments about the same thing from others. But obviously there are plenty of people who like Dell monitors so it's all personal preference. I was coming from a CRT and it was my first shot at an LCD if that matters but still it was immediately noticable to me. Maybe lighting plays a role too *shrug*
Given their return policy (if it's still the same) I don't see any problem recommending people try Dell monitors. The strong anti-glare is just something that for people who know they don't like it to the extent it's a deal breaker want to know ahead of time so they just won't bother.

I've got a refurb 3007WFP-HC and it's definitely got the sparkliness going on. I only really noticed it when I first got the display and was scouring for dead pixels (got a couple, but they're hard to see, and the rest is immaculate, so I kept it). I guess I've gotten used to the sparkling, which is a much better term than grainy. It's never bothered me. I strongly prefer it to seeing a reflection of myself like a gloss finish.MadMan007 - Saturday, January 23, 2010 - link
I guess that's what sucks about being ugly :( ! lol :Ddasgib - Friday, January 22, 2010 - link
Thanks for your answer.Just to clarify: large white areas are shown as large, white areas, not as "large dusty/grained kind-of-white-but-not-really-white" areas? ;-)
Anyway, I'm really looking forward to the release of the devise. I haven't found any 24-inch that has no crappy colours or that frickin' grain :(
The LP2475w has _incredible_ colours and a very deep black - but it's extremely grainy - even in comparison to a really, really old and really cheap 22-inch TN panel.

If he says it looks the same as the 3007WFP then it likely has the typical Dell anti-glare coating. I just don't think he knows what it looks like or doesn't notice it any more. It just doesn't bother some people.hadphild - Friday, January 22, 2010 - link
Does this monitor cope with different Hz ranges?I am really looking for a monitor that can cope with all hz range up to 60hz. I work in a pro video environment and regularly need to use 50Hz outputs.

The only reason I'd see a gamer wanting this is if a resolution that high is really worth sacrificing size since you could just get a much larger (42"?) quality 1080P HDTV for roughly the same price.erple2 - Saturday, January 23, 2010 - link
If I'm doing work? Yes, I'd much, MUCH rather have more vertical pixels than a larger screen, no comparison at all. I'd pay significantly more for it too, than a "High Quality" TV with crummy resolution.I love the 1920x1200 15" screen on my laptop, thank you very much. I love the fact that I can see 4 windows at the same time on it. Using the company provided 14" screen with an (IMO) appalling 1280x800 resolution makes me feel so ... cramped.
