Dell U3014 LCD Review
by Chris Heinonen on April 15, 2013 2:00 PM ESTFor AdobeRGB calibrations, we target the AdobeRGB gamut, with a power law gamma of 2.2 as the specification says. We go for 200 cd/m2 as there is no official luminance target, and we used CalMAN 5.1 to do this as well. Everything is done using a C6 meter that is profiled from an i1Pro.
After the calibration, our RGB balance is perfect, as expected. Perhaps you can see a couple points where one color is 3-4% higher, but those are few and far between, and we have an overall CCT of 6482K here. The greenish tint is long gone, and black and white images look totally neutral on this display now.
Our gamma curve only has a small little bump up at 5%, but as you start to run out of as much control in the monitor down low, it’s really pretty close. The overall average comes out to be 2.21, almost perfectly 2.20, and that highlight issue we saw before is gone.
The grayscale with this combination of results shows no issues at all. The average dE2000 is 0.57 and a couple points get close to 1.0, but really there is nothing to fault here after calibrating, nothing at all. The contrast ratio is 894:1, which is slightly better than sRGB but close enough that a small stray bit of light on the 0% measurement would easily cause that difference.
Colors were already good, but the average dE2000 drops down to 1.03 now that White has been corrected. No color gets past a dE2000 of 1.5 and the color points are all very close to the CIE targets. We have a slight bit of under-saturation in Red and Blue still, but even with that they are very close to ideal. Dell manages to use this LED setup to have a full AdobeRGB gamut, which is nice to see.
Now our Gretag numbers are excellent. The average error is a dE2000 of 0.80 and there is no luminance errors to be seen at all. A few numbers are closer to 1.5, but overall you are not going to see anything wrong here. A worry with any display with a larger gamut is that it is only going to get one gamut right, either sRGB or AdobeRGB, but not both; the Dell U3014 manages to do both with near perfection.
The saturations aren’t quite as perfect as they were for sRGB mode, as Red and Blue don’t quite get all the way out there, but only a few pass a dE2000 of 1.0 and then just barely. The average dE2000 of 0.98 is fantastic and shows the U3014 does a very nice job with its electronics and LUT for building a uniform display.
Using CalMAN, we get flat out superb measurements from the Dell U3014 monitor. Before calibration they are good but not excellent, but after they are nothing but excellent. Dell also has their own calibration software that works with the U3014 and an i1DisplayPro sensor which they provided, so perhaps that can coax even better performance out of the display. Let's check that next.

We have four, and they're all 'responsive', but don't go labeling them as 'ergonomic'. Still, since you rarely perform complex settings adjustments after initial setup, they're probably a better choice for longevity over cheap mechanical buttons that may wear out.cheinonen - Monday, April 15, 2013 - link
I didn't test the U3011, but the U2713HM and other Dells that I have tested have had the actual buttons, which I love. I wish they kept it that way, looks be damned.p05esto - Monday, April 15, 2013 - link
Yea, I have the U2713HM and like the phyiscal buttons. I hate all the "touch" controls companies try to shove down our throats. Nothing beats pyysically raised buttons with tactical feedback when pushed. This goes for just about any gadget. Cameras with touchscreens are soooo useless for example.chubbypanda - Monday, April 15, 2013 - link
Aging Dell U2410 also has touch buttons (with motion detection) and real power on/off button. Kind of annoying, but it's bearable. Looks better than physical buttons on U2412M of course (the overall design is better actually).blau808 - Monday, April 15, 2013 - link
I have/had the U3014 and the U2410. The U3014's touch sensitive buttons are anything but. Sometimes it takes 2 or 3 touches to get it to activate whereas on my U2410 I never had a problem with the touch sensitivity. So they changed something that put them a step back from their previous solutions it seems.blau808 - Monday, April 15, 2013 - link
I recently purchased one of these and am now in the process of sending it back. While changing any of the preset mode (game, multimedia, etc) the monitor turns to severe static and artifacting. In standard preset mode, the reds seem to flash on and off turning the screen a bluish tinge before flashing back to normal. I am truly disappointed and keep telling myself thats what I get for being an early adopter. Hopefully the next panel I get wont be a dud.CSMR - Monday, April 15, 2013 - link
Excellent to see continued progress in monitors.One question is why the review focused more on sRGB and AdobeRGB modes than Standard? The usual advice is to always have the monitor on Standard and let Windows do all the color conversion.
cheinonen - Tuesday, April 16, 2013 - link
If you use Standard mode, you aren't certain what the gamut that its using is (probably a larger one than sRGB), and then you're dependent on Windows to manage colors, which means you need to have both an accurate ICC profile, and every application to be ICC aware. sRGB will force the monitor to use the proper gamut for 99% of things (very little properly uses AdobeRGB, but for those people that need it, it's essential) and you don't need to have Windows and the applications be ICC aware.CSMR - Tuesday, April 16, 2013 - link
Getting this monitor and using sRGB would be a real waste. People who buy monitors like this know that they want a wide gamut and precise calibration. Yes there are some applications that are not color aware and give wrong colors on a calibrated monitor, but 1. these applications are not color critical or else they would be ICC aware, and 2. the gamut would be right as that is done via a global setting (LUT) in the graphics driver.cheinonen - Thursday, April 18, 2013 - link
And that's why there are multiple calibration modes available that you can save, as well as included software that will switch the display between those modes when working in the correct application. So if Photoshop requires AdobeRGB and Premiere needs sRGB, you can have the monitor switch on-the-fly between those two.Of course, if the included calibration software worked better, so you could have more accurately calibrated modes saved to the CAL1 and CAL2 presets, that feature would work even better.
