So they are pretty similar in end result then.
so I've used "dispcal -v -yc -t6500 -qh test" then "dispwin test.cal"
BTW, does dispcal reset the LUT before calibrating or should I reset it with some other app ?
dispcal takes control of the LUT for the calibration, and should restore the contents when it exits.
I've used the pre-calibration options(choice 5) of dispcal to set the OSD properly,

Usually for a CRT, the contrast control affects the white level, so you'd adjust it in the menu item 3, while the CRT brightness control affects the black level (menu item 1). For LCD's it's almost impossible to know what a "contrast" control does, since it doesn't relate to the display device, but is purely electronic, so the best advice is to set it to it's default setting (if you can figure this out).
I'll try on my DLP projector during the week-end, the s2pro did a pretty poor job

Yes, it's accuracy does improve with longer integration time. I've fiddled my driver to do that automatically to some degree, but it's hard to know what sort of trade-off is reasonable.
do you think I would see some major improvement if I upgraded to a Eye One Display ?!
Hard to say. They use what is basically the same sensor, it just comes down to the filters, geometry, calibration and drivers. The Spyder is somewhat more sophisticated, having seven sensors and filters, but I'm not sure whether this turns out to be much benefit in the end or not. Graeme Gill.
