Dell U2713HM Color Quality

When testing the Dell U2713HM my standard way, using a 2010 Macbook Air, my initial performance numbers were not very good at all. Some investigation found that on the MacBook Air when using DisplayPort sends YCbCr color information instead of RGB color information, and so I was getting worse results. Using a StarTech MiniDP to DVI adapter let me drive the Dell at full resolution but in the RGB colorspace. This issue didn’t happen with an ATI or NVIDIA card, so I have to think it was something specific to the MacBook. When using this display, make sure to check the video signal format, as it handles RGB much better.

Dell includes a report for how the monitor should perform, and unlike other vendors that promise a certain dE, Dell shows what they tested and what the results are. These only apply to the included sRGB mode in the display, so you should make sure to use that, and reset your video card LUT, to achieve these results.

Our targets for calibration are D65 for the white point, 200 nits of light output, a gamma of 2.2, and a minimum black level. Once set up correctly, using the included profile and sRGB mode, the Dell provides the best out-of-box performance that I’ve measured so far. The average dE is only 3.15 and the maximum value is only 5.75, which is lower than the average of most displays. Dell includes a calibration report in the box and in this case it really seems to have paid off. For most people, this will likely be good enough performance as it is quite accurate and the errors should be mostly invisible to the naked eye.

With such stellar out-of-the-box numbers I had really high hopes for how the Dell would perform after a calibration. For reference, in YCbCr mode I only managed to calibrate to a dE of around 3, which is far worse than the 1.62 from RGB mode. This outperforms almost all of the 27” displays seen to this point, and those that do out-perform it cost significantly more. There are no issues with the grayscale or anything else after calibration, and you wind up with a very nice, accurate image. It is significantly better than the pre-calibration one, but many users will be fine without the extra step.

When targeting 100 nits of light output for print work, we see a dE of 1.85, which is good but not as excellent as the 200 nits numbers are. On this test the best monitors manage to do much better with those tricky shades of blue than the Dell does, but this doesn’t really worry me that much. Blue is the color we are least sensitive to, so errors in blue are more acceptable than errors in greens or reds. The Dell produces very accurate shades of green and well-rendered skin tones, making it a good choice for more color sensitive work. It isn’t as excellent as the NEC is, but it is around half the price.

Overall the Dell has very good results on the calibrated results, and the best results that I have seen by far on the pre-calibration numbers. If you want accurate color but don’t own equipment to do the calibration yourself, Dell provides results better than anything else I have seen and the included calibration report and testing hopefully means this isn’t just a random sample that happens to be excellent.

As with all the LED backlit 27” IPS displays, we see the sRGB gamut being covered but not AdobeRGB gamut coverage. The Dell manages to cover over 79% of the AdobeRGB gamut, which is pretty good for a panel without special backlighting, so for normal sRGB work it should do a very good job.

    Thanks for doing this review. I appreciate the time and work put into it.
    This is exactly what I've been looking for.

    sorry i meant we are seeing 10-20ms on models with a scaler...still not enough to be that concerned about Reply
  • haukionkannel - Thursday, October 4, 2012 - link

    There is a lot of talk that imput lag may be due scaler. Any chance of getting allso 1440 mode imput lag in comparison. Not all monitors can do it, but it would be nice to see... or is is impossible because you can not get comparison from ctr? Reply
  • cheinonen - Thursday, October 4, 2012 - link

    No 1440p CRT available means no available no-lag reference display unfortunately. I'll be done with 27" displays here soon I imagine and back to displays that can be tested for lag. Reply

    Since you are running several color calibrations with extremely expensive tools, why not provide the resulting ICC profiles to readers on the website? I'm certain the demand is there. Reply
  • cheinonen - Thursday, October 4, 2012 - link

    I don't provide an ICC profile for a simple reason: Monitors (and projectors and TVs and everything else I review and calibrate) are manufactured with a certain tolerance on every component inside of them. If I pull 10 displays off the line and put the same settings into them, I'm almost certain to get 10 different results. I have no way of knowing if the settings from one display are going to benefit or detract from another display.

    I fully realize I can put up the ICC file and say "Here it is, use at your own risk", but I also know that same ICC file is going to wind up hosted somewhere, or passed to someone as an "AnandTech U2713HM Calibration File" with no explanation as to the fact that it might make your display less accurate, and then a user will either wonder why their display is worse than before, or believe that the review it came from was obviously flawed because that file didn't work for them.

    Basically, there's no way to get a display more accurate aside from having your display calibrated, and sharing settings is just as likely to make a display worse as to making it better. I always mention the preset mode I used for testing, as I try to find the most accurate one, but that's the long reason behind no ICC profiles being shared.

    TFT Central has a review of this monitor and they put up their calibrated ICC files for download. Reply

    It's bizarre that this review does not compare against what is quite possibly the most relevant monitor to compare against, the U2711, which the U2713HM would seem to replace. Dell still sells the U2711, for that matter. Surely it's relevant to see how this model compares to the previous model, since this review gives no indication beyond cost of why somebody should choose the U2713HM over the U2711. Reply

    Dell usually runs periodic sales though, so I'm hoping I can do it for under $2k. Reply

    Hey, I might have missed this mentioned in the article. Does it have the same antiglare coating that the U2412M has? I have one, and the spotty/blur that it causes on white backgrounds can be pretty annoying. Reply
