Dell 3008WFP-HC

After calibration
Default settings are disappointing. There is a noticeable dominance in grays while in other colors it’s even worse. One good point is that the OSD offers a number of adjustments as well as being well conceived and clear. We take a look at this in more detail on the following page.

Either way, to more precisely correct colors, the only solution, or at least the most accurate, consists of carrying out a calibration. We put this screen through ours, everything being automatic. The operation takes 5 minutes after which we have the following differences in colors:

IPS 8 ms : Dell 3008WFP-HC
  • Average difference, dE94 = 0.5.
  • Black level: 0.32.

    It’s better but to be perfect black levels would have to be deeper – at least in presettings with a brightness of 200 cd/m². This is a comfortable setting and recommended for most uses.

    For those looking for a display as close as possible to their previous CRT or more "paper-like" rendering, take the time to lower the overall brightness. The best settings we found were Brightness at 39 and Contrast at 40. Black then goes down to 0.24 cd/m² with an average dE of 1.7. Black levels improve while the contrast ratio and overall color fidelity worsen (although we still have a very good value!).
    Homogeneity of colors
    This time we place the sensor on various points of the panel to verify if the colors are indeed the same everywhere. Or to be more precise, we measure the differences as there always are.

    It’s a process that we reserve for high end screens because this test isn’t without its problems. Homogeneity depends on the screen’s transportation conditions and small shocks can noticeably affect this quality. Between the boat, truck and then the car trip home, there are many factors beyond the manufacturer’s control...

    High end screens should be particularly well packed for exactly this reason. In our opinion, the 3008WFP-HC should be amongst those monitors for which we expect the maximum quality.

    More specifically, between the brightest point (in the center) and the darkest (upper right corner), we measured a difference of 29 %. This is significant but not uncommon and characteristic of classic entry/mid-level screens.
    Once again, we were surprised that such a monitor has rather "normal" and non-exceptional rendering, something we wouldn’t expect given its price. This is all the more true because Dell has shown better on its 27’’, the 2707WFP, which only had a maximum difference of only 13%.
    So is this 30 % gap really a problem? Luckily, no, as the transition is progressive and spread out on a very large surface. Unless you display a single color and really look for the differences, this shouldn’t bother you.
