Energy consumption
Consumption is measured with the display of a standard photo.
In the same way we see "Beware of dog " signs, the 3007WFP should have a warning on its package of being a big energy user.

IPS 8 ms : Dell 3008WFP-HC130 Watts at 200 cd/m² in white! It’s more than triple the measurement of a normal 22 inch! It’s the equivalent of 11 low consumption light bulbs (11 Watts).
For comparison here is the energy use of the Iiyama E2403WS, a rather efficient 24 inch:

TN 2 ms : Iiyama E2403WSConclusion
The 3008WFP-HC is a great and very practical screen but don’t expect high performances. It has poor factory presettings, is subject to latency, input lag, shimmering in movies and it consumes too much energy. If only the inside had gotten as much attention as the exterior!
There are indeed problems. For this reason, we are a bit frustrated and had the impression of not getting our money’s worth. In the end, Dell ambitious price isn’t on par with the actual qualities of its monitor.
To this, they could reply :
Yes, but you forgot to mention that it is a wide gamut. This was done on purpose!
The gamut on the 3008WFPThe wide gamut has started to pop up everywhere. And then manufacturers realized that it is often not a real plus. You have to be meticulous to actually take advantage of it ; use the wide gamut when the source or target are well adapted (a reflex that functions in the Adobe RGB space, a pro color printer, etc.) and then come back to normal settings the rest of the time. This means permanently juggling between two states and therefore two profiles. Without a calibration device, this is a problem!
So what we really didn’t like with this screen were the imprecise factory pre-settings. As much as the user is given the option to switch between two modes, these should have been more accurate.
The ultimate question : what does the 3008WFP-HC add compared to the 3007WFP-HC ?Here we have to go back to the test of the former model. More or less this is what we wrote: poor color fidelity with default settings, brightness homogeneity varies roughly 20%, good reactivity, an IPS 6 ms panel, and wide gamut. We precise that at the time, some tests were lacking such as measured contrast and energy consumption. Nevertheless, our conclusion is that the biggest change is only in terms of the bezel and even the price. It’s really just an aesthetic update of its predecessor. So should we be surprised? No. There aren’t many 30 inch screens, the demand for them is still low, and their revision is almost inexistent. In short, the panel is the same, or at least it wasn’t radically changed and without great surprise, this screen’s behavior is more or less identical.
