Dell UltraSharp U3417W review: update of a favorite

Extremely good colour quality with clear downsides

By


Colour quality

The colour quality of its predecessor was remarkably good, probably because Dell calibrates their UltraSharp monitors in the factory. For this reason the U3415W ended up at an excellent colour temperature of 6567K and a respective colour- and grayscale deviation based on DeltaE 1994 of 1.5 and 2.5. Because of this we are curious to find out how the new monitor performs, which we test with a significantly more demanding set of tests using a more modern, stricter standard.

To start off we take a look at the coverage of the sRGB colour space of the Dell UltraSharp U3417W, a measurement that we did not do with the older model. We end up at 99.1%. An excellent result.

Secondly we look at the colour temperature of white with the standard setting. With a value of 6516 K this monitor is even closer to perfection than its predecessor. 

Looking at the colour deviation, the U3417W shows an excellent value of 0.93. Furthermore the standard deviation is very small as well: all individual sub measurements vary very little. This is a new level of calibration that we usually only see with a lot more expensive monitors – and even there it is exceptional.

The grayscale deviation is impressive as well. The white point is neutral and the grayscale barely shows any variation. 

Standard

Below you can find the detailed measurements of the colour analysis. Note that there is nearly no sub colour that deviates in a meaningful way. The only outlier is 100% red and the ‘fault’ there is slightly more saturation than desirable according to the sRGB-standard. In practice we cannot call it a disadvantage. The only other negative on the otherwise clean slate is the brightness of black, which is slightly high.

Gamma 

The gamma value is excellent as well, on average we measure 2.17, a very modest deviation of the desirable 2.2 and not bothersome in practice.

Standard gamma

The gamma course follows the desirable line nearly flawlessly, the sub colours are very well balanced, and there is no colour deviation at all. This is exceptionally good.
