Let us first mention the contrast, which does not sparks here! With a score of 1098: 1 measured by our probe, it is a little pale appears in front of other models that we have tested recently, such as the Ultrasharp U2724D Dell. Let us hear, this is not a catastrophic value, especially for a screen mainly intended for office work. On the other hand, this is a point to consider if you plan to play or watch videos with this screen.
On the other hand, it perfectly fulfills its contract in terms of maximum brightness. Announced at 400 cd/m², we measured it at 394 CD/m² in SDR, a very correct score for a screen at this price. We nevertheless regret reflectance a little high with clearly visible reflections in a well -lit room. We measured an average of reflections of 20.6 %, despite a matte slab. Correct, but some descend to 8 %.
Admittedly, the colorimetry is not perfect, but this screen is getting away with honors, at least in SDR. We calculated an average delta e of 2.51, which is lower than the fateful 3 from which the eye begins to perceive the drift of colors. This is at least the case in SRVB mode, not selected by default. It should be noted, however, that certain colors, especially red, deviate a lot from the ideal value.
The color temperature, measured at 6908 K, is not frankly ideal, because it is quite much higher than the 6,500 k of reference. The result is a globally a little cold image. As for the gamma, it displays an average of 2.14, slightly below what we expected. In particular, there is weakness on the darkest tones, which can generate a somewhat washed -out aspect in dark tones.
HDR
This screen is HDR compatible, but does not excel in the matter according to our tests. The colorimetry then loses clearly in precision: most of our reference colors derive largely beyond a delta e of 3. results in a medium delta of 3.6, which clearly shows a general drift in the return of colors. The coverage of the colorimetric space is nevertheless rather satisfactory with 96.3 % of the DCI-P3 spectrum.
The EOTF and Luminance curves also show the weakness of the screen in terms of maximum brightness in HDR. Thus, the device fails to offer the expected brightness, especially in terms of luminance. It must be said that the maximum brightness that we have measured in HDR is low with only 377 CD/m².
