Power 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. 

LCD Power Draw (Kill-A-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?

    Dell outlet has these from time to time for $899. When they pop up, they go fast. I got one last week and it's top notch (coming from 2408WFP). I'm using it primarily for PS CS5. I calibrated it and I'm well pleased with my prints. Awesome display.

    It's a pity they didn't go to LED backlighting instead of CFL.

    The monitor is already over a thousand bucks, so a few extra dollars shouldn't matter much, and it would benefit greatly from a reduction in power consumption, as well as the reputed gains in picture quality that comes with LEDs.

    LED is a benefit for power consumption, but it can actually be a detriment to image quality. This monitor's CCFL backlight allows for a wider color gamut than WLED would, which is why they chose it.

    Great video showing the clear input lag winner. A shame... without the lag, and with the audio output, this would be a nobrainer for me. The limited inputs on the z30 make it less attractive, but still moreso I think.

    As an aside, I did a similar comparison to this using my M6500 and a trusty dusty 2001FP I still have from 10 years ago. About 1/3rd of a window similar in size on that test behind for the old Dell.

    Things have gotten better, but for $1300+, I think I'll sit the fence.

    I really like seeing displays reviews benched with meaningful metrics.

    I want MORE,,,

    why do all the 30" monitors miss speakers? (the DELL speaker bar for the 3008 is worse than my worst notebook computer. I don't need much, but the DELL speakerbar is really bad.) and yes, many people just like having a one-in-all monitor. heck, I would even like a webcam in it, but I understand that this is not a common need. I would also not tuner while we are at it, but again, this is not needed.

    but speakers?? come on.

    for lack of speakers you should subtract a half-star.

    DisplayPort has some problem with power management. Won't wake up after going to sleep. Too bad, it's a really sweet monitor visually.

    The review states that there is no pivot mode.

    Are you sure that this has no pivot and cannot be used in portrait mode?

    Dell have confirmed in writing to me that it can pivot and do the portrait mode!

    I want to use two of these monitors side by side. I have an Nvidia GTS450. Will it work?

    I dont understand why 30" Monitor so expensive than usual 40" TV? Is it really worth buying a 30" TV than 42" or 46" high end TV at the same time? If resolution is not the priority or preference or use then better to go with TV than a monitor. Anyways we r still way behind the technology like how Anandtech rightly introduced us right at the start.
