I got 7 on my iMac Alu 24". Monitor has not be changed from Apple defaults. It's definitely too bright for an ideal photo editing screen, but the colour accuracy is clearly fairly good.
7 on the Dell 2408WFP I received yesterday. I run Linux so none of the hardware calibrators will work for me. I calibrated it by eye, and I guess I did OK. I am male, 58 years old. Worst for my gender & age range was 1429. That guy must have been color blind.
I got a zero on my calibrated 20-inch apple screen and a 10 on my uncalibrated MacBook Pro screen, which I about what I would have expected. I think the test is cool too.
20 on an uncalibrated Dell LCD in bad flourecent light at work, in only a few minutes while on a phone con. I'll have to try it again at home in good light and on my calibrated GDM-FW900.
I am curious to know if any of the colours in the test are technically out-of-gamut for consumer LCD panels (laptops and non-pro grade TN LCD panels). Seems like many people are getting good results on these inferior screens.
I suppose it's reasonable to assume that even if a monitor does not have accurate colours, you would still be able to get the relative order right provided that none of the colours were out-of-gamut.
I am getting an Apple Cinema Display soon (S-IPS type panel) so will test again on that to see if it makes a difference.
