Dell U4320Q Connections
This 43" of the new Ultrasharp 2020 range has all the connectors you would expect: HDMI but in version 2.0, DisplayPort 1.4 but also the famous USB-C, so practical, especially since it is now capable of delivering 90W. So very good in 2020, at the time of the launch of this monitor
What is the Dell UltraSharp U4320Q display worth after calibration with the i1 Display Pro?
I calibrated this display - like all the displays I test - with the best current sensor at a simply excellent price/performance ratio: the i1 Display Pro+ i1Profiler software (version 1.8.3) in order to be able to locate this new panel in relation to the other displays on the market. I connected it with the HDMI to HDMI cable and then USB-C to Display Port without any change.
I chose the following screen settings:
- Color mode: Standard
- Brightness: 24/26% for 90 cd/m2 target,
- Contrast: 75%
- Enlargement in Windows to 125% to ensure the correct software window size at the time of the uniformity test.
Essential! Reset the monitor to factory settings AND choose your computer's generic profile before calibrating on Mac (Monitor Preferences) or sRGB on PC!
And as target values in the i1Profiler software (1.8.3 at the time of this test) in advanced mode
- Display technology: white LEDs,
- D65 or possibly a little less if you want a slightly warmer screen. (Note that at D55, the screen becomes more yellow than warm, unlike high-end screens),
- Luminance: 90 cd/m2 for a photographer who prints or more depending on your primary use, web or video, plus in a bright room,
- Contrast: Native,
- Gamma: 2.2 - Standard curve,
- ICC standard: V2 to avoid problems of incompatibility with some image viewing software (images too dark especially in Windows 10) and obviously V4 if you know what you are doing.
And the result is?
First subjective impressions after this calibration?
Even at the cardboard outlet, the panel displays neutralized gray so it can only be better after calibration but the base is "healthy".
What does the final report show after calibration:
The color temperature (TC) of 6502K for 6500K target is of course perfect! The contrast, measured at 90 cd/m2 I remind you, is 673:1 and is therefore in the "normal" range of white IPS LED panels in 2019/2020 for photo rather than video use (which accommodates more contrast). Black at 0.134 cd/m2 is ideal for those who print but lacks a bit of depth for the black stripes you see when viewing a movie.
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 monitors on this site :
The average Delta E norm 2000 is 0.79 so very good in absolute but rather standard if I look at the average of my tests. That said, if we put this monitor in its context given its size, it is rather rare to see control monitors or to share such good images with others.
The Delta E of 2.80 for the worst patch is, in absolute terms, not negligible for a high-end or Ultrasharp display but there is nothing to worry about in practice because a single patch is a bit below the overall average (see below)! Luckily, this color is not a flesh or sky color. And curiously, only this patch is really bad. All the others are in an excellent average. It is even surprising.
Note! I insist a lot on the fact that the first vocation given its size is not to do photo retouching alone but to share a monitor to work in a group and in this context, this monitor is then above average.
Now the luminance uniformity tests:
Important! Unlike many UltraSharp displays, this Dell does not offer the Uniformity Compensation option. We will see that this is not disabling.
We're in 2020 standards, not overzealous! But then again, if in absolute terms it's not "incredible", what is more incredible is what we're dealing with a 43-inch panel.
... and color temperature:
The results are in the good average with a maximum delta e of 1.7. And in real life, it shows: the panel is very homogeneous.
