Why does my Dell U2412M only show about 79% Adobe RGB after calibration?

I’m calibrating a Dell U2412M/U2414M with a Datacolor Spyder4 and expecting full Adobe RGB coverage, but the calibration result shows only about 79% Adobe RGB. The monitor is set to its Adobe RGB-related mode. Is there a way to calibrate it to 100% Adobe RGB, or is the panel itself the limiting factor?

Carol, are you sure you have the U2414M? That's Dell's medium gamut variant of the monitor, covering about 75% of Adobe RGB. So I think that if that's the monitor you have, it's behaving as expected.
See this review on TFT central for details.
Dell's terminology here is unfortunately confusing, since previously the U2413 (with no M) was the wide-gamut variant, but now the new 2415 (still no M) is also only standard gamut (albeit with a respectable 99% coverage of sRGB, similar to the U2414M). It looks like Dell is now using the term PremierColor for its wide-gamut displays — see this list on their web site.

You generally can’t calibrate a monitor beyond its native color gamut. Calibration can improve accuracy, but it cannot turn a standard- or medium-gamut display into a true 100% Adobe RGB display.
Based on the community answer, the Dell U2414M is only around 75% Adobe RGB, so a result near 79% is in the expected range. If your model is actually a U2412M/U2414M rather than a true wide-gamut Dell, the monitor itself is the limitation—not the Spyder.
Dell’s naming has been confusing: some models without the “M” designation were the wider-gamut versions, while many “M” models are not full Adobe RGB displays. In practice, if you need close to 100% Adobe RGB, you need a monitor specifically designed for wide-gamut/PremierColor-class coverage.
So the answer is: you likely cannot reach 100% Adobe RGB on that display through calibration alone.
