Dell U3011 Review: Dell's New 30-inch Flagship
by Brian Klug on January 13, 2011 9:17 PM ESTPower Consumption
The 30-inch category of displays have always been power hungry, and the U3011 is no exception. Laws of physics still apply here, and when it comes down to it, there's just a lot of area to fill with photons. The U3011 specifications note that power use of 250 watts is maximum, 110 is typical, and standby is around 1 watt.
At maximum brightness, the U3011 draws 144 watts. At minimum, 73. That's just slightly below the ZR30w, but not really enough to make it notably better or worse.
We don't measure it directly, but subjectively the U3011 feels surprisingly cool. There isn't a ton of heat which seems to come out the top grilles, nor a ton of heat coming out the front (unlike my BenQ FP241w monitor array which seems to noticeably warm my face).
Conclusions and Final Thoughts
The U3011 is an all around good performer, though I find myself wishing that contrast and Delta-E were just a bit better so it was an unequivocal winner in all the right areas. That said, it does have a number of advantages over the HP ZR30w, namely an OSD, a wealth of input options, and audio pass through. Where the HP ZR30w bests the U3011 is with its excellent display arm which feels subjectively sturdier and beefier, and its slightly better color performance and input latency. Heck, maybe there's something to be said for not having that display controller SoC.
If accessory inputs like an extra DVI and HDMI port are what matters (not to mention the option of having 5.1 audio out), the U3011 is the better choice. As an all around desktop display, the ZR30w edges out in my mind purely because of the slightly better display performance and build quality - it feels solid and just seems to have a much beefier display arm. It's a tossup that ultimately comes down to what features are really most important, and price. Right now, even price is a tossup, as the two are priced within $10 of each other on Amazon. Personally, having HDMI with audio pass through and all the scaling options makes the U3011 the better pick, but again that's just my take. Now the question is: who will be first to market with a 120 Hz 30-incher?

I am running the 3008wfp now and I am extremely interested to know how it compares to this new one? Any insight on it? Or maybe an update to include more 30" models that have been around for awhile? Thanks for the awesome review otherwise.B3an - Saturday, January 15, 2011 - link
I'd like to know this as well but dont think that monitor was ever reviewed on here. Weird considering how popular it was.I have the 3008WFP and also the HP ZR30w thats been reviewed on here before and also mentioned in this article.
They say the HP's colours are slighter better than the new Dells when calibrated, well theres not even much difference between my HP ZR30w and my older Dell 3008... but it is better (i have them both colour calibrated too).
And the HP also has more uniform backlighting with less bleed, and theres no noticeable lag.
I couldn't even notice the lag on the Dell 3008WFP until i got the HP monitor, had them both running side by side, and dragged a window down the middle between them. On the 3008 it lags about half a centimetre behind and it seems the lag is still there on the new Dell...
Another thing is, the HP switches res a lot quicker.... the 3008 can take it's time to come back on when the resolution is changed, pretty annoying. I'd like to know if the new Dell also does this.

I've got a 3008WFP too and I agree that the res/input switching lag is rather high on it. It's quite annoying because it takes a lot of time for the display to come out of sleep. The OSD also seems much improved on the 3011.However, I haven't noticed input lag on my A02 revision. I have a Sony HDTV that according to hdtvtest.co.uk has 0-10 ms input lag and running both displays in clone mode I saw no real difference between them.
Have you run into problems with colors on the HP? Since it has no OSD, things like games should reset colors to whatever is calibrated from the factory because they don't understand color profiles. At least the 3008WFP has terrible color presets before calibration so I imagine that would be an issue if there are no hardware controls for color settings.

I have an A02 revision too. The only way to really see lag is to have another display right next to the 3008 thats the same size/res, then have an extended desktop spanning across both displays, and drag a window down the middle, so half of the window is on the 3008, and the other half on the other display. Even then you can only just see it.Colour with games isn't a problem much on the HP, it's default colours are pretty good, just a little cold. They're much better than 3008's factory default, and it's harder to notice with games compared to the desktop anyway.
If the HP had the Dell U3011's OSD and the card reader, then i think it would be the perfect display.

Hey B3an,Iahev a U3011 and I can say it DOES still take its time switching resolutions. No change there.

Brian,How would you subjectively compare the U3011 and the U2711?
I am personally on the fence, debating whether the price difference is worth the 3 inches.
For me, I would use it primarily for general office use, followed by Photoshop/digital photography, and then gaming last.
Thanks.

I think quality wise both are pretty close, and I've seen the U2711 for extremely cheap on slickdeals and other places occasionally. Granted, I did see the U3011 for $1045 last week as well, so it's one of those things that's entirely luck-bound.Honestly I'm a bit partial to the U2711 because of it's lower pixel pitch/higher PPI (I'm a fan of insanely high PPI). That can also be a downside if you have a hard time reading text without scaling.

Comparing the Anandtech reviews, the U2711 seems much better designed. The minimum brightness level of the U3011 of 159cd/m^2 is well beyond a normal optimum brightness. (See http://www.eizo.com/global/support/wp/pdf/wp_08-00... )It's as if Dell thinks their monitors are going to be used outdoors in broad daylight.
Also some photographers are suspicious of dynamic contrast - I haven't looked into this, but if you don't use dynamic contrast, the black level on the U3011 is going to be unacceptably high (as the figures in the review show).
DanNeely - Friday, January 14, 2011 - link
The upper brightness is driven by a combination of sharing parts with TVs (if you're farther away the optimum brightness is higher than for a monitor right in front if you), stats inflation (idiots who think bigger numbers are always better), and to make it look good in show rooms that typically have ambient lighting cranked to excessive levels (it supposedly helps hide the crappy nature of cheap panels). The high minimum brightness is because CCFL backlighting can only operate over a brightness range of about 2.5x, so the minimum is always ~40% of the max.I'm not sure what you're getting at with the dynamic contrast comment. The blackest black will be just as dark with brightness at minimum as with dynamic contrast turned on, and because of the standard overpowered backlight it will probably be near there most of the time to remain comfortable to use.
CSMR - Saturday, January 15, 2011 - link
I don't fully understand the measurements of dynamic contrast. It does seem to me that if they advertise a 10x advantage in contrast ratio with dynamic contrast on, and getting their figures from 2.5* the lowest brightness setting, that the lowest black level is 10/2.5x less than it is without dynamic contrast and with minimum brightness. Unless there is some additional way to cheating on the figures?A black level 4x lower would be very acceptable.
