Dell U3011 Review: Dell's New 30-inch Flagship
by Brian Klug on January 13, 2011 9:17 PM ESTBrightness and Contrast
For brightness we display white and black levels at maximum and minimum brightness as allowed by the OSD, and divide the two to get contrast. We use the same colorimeter described earlier. In this case, an Xrite i1D2 with ColorEyes Display Pro. For the U3011, dynamic contrast is turned off, contrast is set to maximum on the OSD, and the brightness control is varied across its possible dynamic range.
The brightness dynamic range on the U3011 isn't really amazing. In fact, it was a challenge to get the display to 100 nits for calibration (it required changing contrast and carefully balancing brightness and contrast controls on the OSD). One look at the contrast ratio plot however, and it's obvious what Dell did here - sacrifice dynamic range control for luminance but in so doing keep contrast extremely stable across that range of brightnesses. It's a tradeoff which actually makes a lot of sense, even if it isn't readily apparent when you're playing with the display, especially because the contrast OSD control visually makes a much larger difference than brightness which actually controls the CCFL power. I took a lot more data, but between max brightness and min brightness, contrast is pretty steady at around 750.
It's a bit unfortunate that the IPS in the U3011 isn't a bit more contrasty, especially when advertised is around 1000:1 with dynamic contrast off. Still, not bad.

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.godel - Wednesday, January 19, 2011 - link
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.spilled - Thursday, January 20, 2011 - link
http://www.youtube.com/watch?v=qrjDbWU_43AGreat 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.http://en.community.dell.com/support-forums/periph...

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?ruzveh - Sunday, May 29, 2011 - link
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.
