The last Dell monitor that I reviewed, the U2713HM, really impressed me by having a very accurate sRGB mode out of the box. It was the best performing one that we had seen to that point, but since then we’ve switched the way that we evaluate monitors and now use dE2000 data that can’t be directly compared with previously tested displays.

Pre-Calibration with the Dell, the sRGB mode was the most accurate, though I did look at the grayscale on every other mode to be sure before I selected it. The Multimedia preset was the closest other than the sRGB, but color accuracy on it wasn’t nearly as good as it was on the sRGB mode. Looking at the grayscale data, we see that there is a bit of a green push there, and our average CCT winds up at 6389 and not quite the ideal 6503K.

The Gamma has a small dip at 5%, indicating that the gamma is an sRGB target and not our 2.2 target, but there is also a large drop at 95% that I see many times in displays. This indicates that the very peak whites are spaced too tightly together, possibly by an incorrect contrast setting or something else in the display electronics. You’ll see highlights be slightly washed out as a result.

The grayscale dE hovers right around 3-5 for most of the range and has an average dE2000 of 4.3. I did measure a contrast ratio of 905:1 in this mode, with whites just over 200 cd/m2 and black at 0.2225 cd/m2. The grayscale is good here but not excellent.

Colors are much better, with the major errors being in white, but overall the luminance levels are very good. That's the most important aspect and the color errors are low. If we could remove white from the average it would be far below the 2.14 we got, but color performance is very good. They also match up pretty close to the targets, with just slight under-saturation in some colors.

The Gretag Macbeth numbers are very good for a non-calibrated display, and we once again see that the grayscale is the majority of the issue here, with colors being much better. That’s a bit surprising to me as often it’s the other way around, but that is just what we see this time, along with some more slight under-saturation. I included the luminance chart here for the Gretag Macbeth data just to show that the U3014 is dead-on accurate with the luminance levels, which is what you want to see.

Finally when we check out the saturations, we see that some colors are very good, like Yellow and Green, but Red has a noticeable lack of saturation across the gamut, and the issues get larger as we get closer to 0%. These aren’t awful numbers, but they're not as good as we could see.

In the default sRGB mode, the U3014 is still very good, and as we get more displays in for testing I think the quality of those numbers will just improve as we see what other displays manage on our new benchmark. Keep in mind that these are all out-of-box numbers so far, where many displays end up close to double digits for DeltaE.

    Small typo in the table of 2nd page. "256x01600" should read "2560x1600". I wanted one of those korean 30 inchers just because it's hard to find good 16:10 IPS panels but sadly, for reasons i can not fathom, they are almost 2x as expensive as the 27 inch 1440p counterparts. So, i eventually ended up buying a 27 inch 1440p panel. Although i'm delighted by my choice nowas this "QNIX QX2710" samsung PLS display that i bought is capable of 120Hz at 1440p without any mods and it's going for 289$ on ebay as i speak. Reply

    Have you actually clocked it @ 120Hz? Reply

    I have a shitty GPU (HD6670) so i get artifacting in fast moving scenes at 120Hz. I'm running this at 108Hz currently and it works flawlessly. Reply

    Love my job, since I've been bringing in $5600… I sit at home, music playing while I work in front of my new iMac that I got now that I'm making it online.(Click Home information)

    How is the input lag on the QNIX? Reply

    Try the HP ZR30W. 2560x1600 wide gamut. There's also a great review here on anandtech. Reply

    Have you noticed any motion artifacts (possibly due to the excessive? pixel overdrive used on this display in an attempt to decrease the advertised pixel response time)

    Indeed, we need usability in review, i.e. overdrive artifacts are way more important than initial color accuracy. Dell U2713H looks great on paper unless you see the movement artifacts. NEC PA271W was pretty awful in this aspect too. Reply

    Hi. I'm the guy whose Dell forum post was quoted in the HOCP forum post. Dell don't want to know at all about this issue. It would be good if AnandTech could put some pressure on them about the hideous pixel overdrive they have set as default.

    The mouse cursor on a white background is bad enough, but grey to grey is especially bad because of the overdrive.
