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.

Would you guys be able to review the new monitors from Monoprice.com? Here is the link for anyone interested.http://www.monoprice.com/products/subdepartment.as...
The 27 inch model apparently uses the same panel as the apple cinema display. These prices are also quite competitive so they have me interested.

I'm talking to them, though I personally think the 30" would make for a more interesting review as we've covered a lot of the 27" IPS panels now. Also, if you look back at the two LG 29EA93 reviews that I did, you can see that the panel only makes up a small part of the performance of a display. The corresponding electronics are a huge factor in performance, so I don't recommend just looking at the panel to determine the performance.Trefugl - Tuesday, April 16, 2013 - link
It is great to hear that you are in talks with Monoprice! I would be grateful for a review of either model, but would be more interested in the one with an OSD. I'm concerned with having a wide gamut screen that has no sRGB mode or color correction on board, tho the potentially reduced input lag of not having processing is alluring as well.cheinonen - Thursday, April 18, 2013 - link
I don't believe any of the Monoprice displays are wide gamut, only sRGB gamut. It looks like the 30" one has a 10-bit panel, but that's certainly 8-bit with AFRC, which might give you better gradients, but won't give you a wider gamut.B3an - Tuesday, April 16, 2013 - link
Chris, i'd really appreciate it if you could help me as i'm thinking of buying this monitor. Do you have any idea at all if the i1Display 2 will calibrate this monitor well? It comes with Eye-One Match 3 software.And what software would you recommend most for calibration? dispcalGUI?
cheinonen - Tuesday, April 16, 2013 - link
Personally, I wouldn't use an i1Display2 anymore for color accuracy. With the design of the i1Display2, and the fact that they haven't been made for a year or two now, the filters degrade over time so that anything it is reading now may or may not be accurate at all. It can read light levels correctly, so white and black light output, but not the colors of light. I have a pair of them here and testing them now compared to the i1Pro, I see dE2000 errors > 10 in the grayscale using it. The standard calibrated modes are going to likely be more accurate.I like dispcalGUI. I haven't used the most recent version, but I've been using it for a long time now and they do a great job adding more and more features to it.

You know what's missing from this monitor? Support for 5.1 output like its out-going predecessor. I make great use of that feature on my U2711, and not having it here is a major deal-breaker. I run my Xbox 360 to the monitor via HDMI and pipe the audio out through the analogue 5.1 jacks to Logitech X-530s. I would not be able to do that with these new monitors.I might be a hold-out, but one of the primary selling points for me on the U3011 and U2711 was the fact that, for a PC monitor, they offered a diverse array connectivity. You can do HDMI, composite, component, DVI, VGA, and DP all on the same monitor. You can also, as mentioned, earlier, output to analogue 5.1 surround. This monitor is not worth the $1500 asking price in light of this "streamlining" of features. If I'm paying top-dollar for a monitor whose predecessor I already own, I want it to have all of the capabilities of that predecessor and then some. $1500 for what is only a good panel and LED back-lighting is a raw deal no matter how you slice it.

Chris, my coworker has a Nixeus 27inch monitor attached to a 2012 MBP. His Nixeus has the same problem of not activating after sleep sometimes as well. A simple power cycle gets it going again for him too. Just another data point to indicate where that particular problem may be.l_d_allan - Tuesday, April 16, 2013 - link
The 2010 and 2011 models are coming down in price nicely. I just ordered a U2410 that should be a significant upgrade from my current Samsung TN panel that only has about 70% of sRGB.The only significant difference I'm aware of to the U2413 is the hardware calibration capability, but I have a Spyder rather than X-Rite, so my understanding is that is a non-issue. YMMV.
cheinonen - Tuesday, April 16, 2013 - link
The U2410 is a CCFL backlight and the U2413 utilizes the G-B LED backlight that the U3014 uses. It also has the MiniDP and DisplayPort inputs and a DisplayPort output for using MST, and USB 3.0 over 2.0. It loses the analog inputs that the U2410 has, so if you have a need for those it is certainly the one to use. Since you're using a Spyder, the calibration software is a non-issue.
