The buttons of the screen menu
The keys of the screen menu are classic, i. e. via small buttons under the screen, slightly to the right of the centre of the screen. The ON/OFF button is illuminated.
The Dell U4919DW connectivity system
This 49-Inch of the new Ultrasharp 2018 range has all the latest connections and standards. So it was very good at the end of 2018, when this screen was launched.
So, what is the huge panel of this Dell U4919DW worth after calibration with the i1Display Pro?
I calibrated this monitor - like all the monitors I test - with the best current sensor (except the superlative and very expensive Discus) in an excellent price/quality ratio: the i1 Display Pro + i1Profiler software (version 1.8.0) in order to be able to locate this new panel compared to the other screens on the market. I connected it with the HDMI to HDMI cable.
 Note on display quality before calibration - This is increasingly a noticeable quality of Dell Ultrasharp series displays: their color display is already more than correct at the factory with perfectly neutralized grays. The image is therefore beautiful as soon as it comes out of the box. Obviously, a proper calibration does not hurt it and reduces its default brightness quite significantly, but a buyer with a tight budget (or broke because this screen is not cheap!) will be able to enjoy a good screen set by default at first and then consider a calibration a little later... Very good point!
I choose the following screen settings:
- Color mode: Standard
- Brightness: 23% for 90 Cd/m2 targeted,
- Contrast: 85%.
 Essential! Be sure to reset the factory settings AND choose the generic profile of your computer before calibrating on Mac or sRGB on PC if you re-calibrate.
And as target values in the i1Profiler software (1.8.0 at the time of this test) in advanced mode...
- Display technology: white diodes,
- D65 or possibly a little less if you want a slightly warmer screen. (Note that at D55, the screen becomes yellow rather than warm, unlike high-end displays).
- Luminance: 90 Cd/m2 or more depending on your main use (printing or web) and especially the brightness of your room,
- Contraste: Native,
- Gamma: 2,2 – Standard curve,
- ICC norm: V2 to avoid incompatibility problems with some image viewing software (too dark images especially in Windows 10) and obviously V4 if you know what you are doing.
And the result is?
First subjective feedback after this calibration...
Even at the exit of the cardboard, the panel displays neutralized grays so it can only be even better after calibration but the base is "healthy".
What does the final report say after calibration:
The color temperature (CT) of 6832 K for 6500K represents a low score on a mid-range display. Saying it shows is another story, so nothing embarrassing! The 1058:1 contrast is in the "high" range of white LED tiles, even if there are starting to be panels with a contrast ratio of 1500:1. However, to retouch photos is perfect. The micro-contrast is also very good, especially on the texts as I mentioned earlier.
Now, let's move on to the famous Delta E after calibration according to the 2000 standard which I use for the calibration of all the screens on this site:
The average Delta E standard 2000 is 0.80 so very good and not so common on mid-range screens and frankly, I did not expect such a score on a panel certainly Ultrasharp but with office or trading rooms and especially unique by its size.
The Delta E of 3.22 for the worst patch (only one that slightly seals the overall average)! Fortunately, this color is not a flesh or sky color. And strangely enough, only this patch is dead in the water. All the others are in an excellent average.
Now the luminance uniformity tests:
Results above the high average for a screen despite all medium range and especially to the huge panel. Again, I did not expect such a result. The perceived reality is the same and it is especially good to note that the panel is so large that the differences in brightness are very progressive so you don't really see it. Usually such figures are found on 27'' panels, so they are much smaller. Clearly, this is a pretty good achievement from Dell!
... and the color temperature:
The results are in the same vein without being exceptional since the worst corner remains below 1.6. But again, this is not really embarrassing in real life.
