I have a few CG19's and
I'm getting the following numbers...
DE2000 Max 6.3, Ave 1.5, white pt. 1.0
DE76 Max 15.8, Ave 2.9, white pt. 1.0

I'm measuring my GRACoL 7 2006 coated1 proof white point inside my GTI booth
instead of selecting selecting 6500, 5500 etc...

Switching the measurement device's compensation table to "none" didn't
change my numbers either.

My CG19's have close to the same gamut as your monitors. We have been using
the CG19's for 3 years now. We know they don't match GRACoL 7 proofs exactly
but they get very close visually. As the DE2000 numbers indicate. It's not a
problem in our workflow because we know the limitation of the monitor gamut.
I've downloaded profiles of several newer Eizo models such as the CG222.
I've compared the gamuts and the CG222 has a wider gamut than the CG19. The
gamut still doesn't cover 100% cyan but it's a lot closer than the CG19 at
about the same price. I would expect that the CG222 and other monitors with
similar gamut size would have lower DE numbers.
