Hello,
We have several workstations with Dell U2410 LCD's. I've calibrated them in the
past with Argyll & dispcalGUI with very good results (deltaE 1-3). Since we
upgraded to 10.8.4 I've been unable to get anywhere near the accuracy.
Typical results Average ΔE*00 of 3.7 to 4.4, and max at 10.8 to 11.2. I've seen
the sRGB coverage at >99% (where it should be) but more often at ~66%. I got
similar values from 3 monitors on 3 machines, and even X-Rite's i1Profiler
seems to generate the same level of (in)accuracy. I've given the monitors
plenty of time to warm up and stabilize.
- i1DisplayPro on Dell U2410 LCD
- OS X 10.8.4
- Argyll 1.5.1, dispcalGUI 1.2.7.0
- sRGB preset on the monitor (not the custom mode)
- Rec. 709 tone curve w/ ambient light measurement (approx. 30 lux).
Command line:
dispcal -v2 -d1 -c1 -yn "-P0.450879765396,0.472049689441,1.49865229111"
-X WGCCFLFamily_07Feb11.ccss

-t6500 -b100.0 -g709 -f1.0 -a31.0 -k0 -A4.0
U2410 2013-08-03 100cdm2 D6500 Rec. 709 HQ 3xCurve+MTX.icc
Any ideas?
Thanks,
Drew Lahat
