Well it says it supports a wide gamut with 82% coverage, I had to look up what that meant, 82% of CIE 1976. The U2410 supports 110% of CIE 1976 (whatever CIE 1976 is, supposedly all the colours the human eye can see or something).

16.7 million colours for the U2412M vs 1.07 billion for the U2410, and the specs for the U2412M don't mention any industry standard colour spaces at all.
It's not a high gamut monitor like most, but because it dithers I guess it could emulate high gamut by mapping a wider range of colours into 16.7 million colours.. you'd think the specs would mention that though.
