Hi there, I have been trying to calibrate/profile my monitor with argyll. I have a Colorvision Spyder 2 Express. The monitor in question is a laptop screen, specifically it is a "Dell 15.4 WSXGA+ with TrueLife". Basically, my attempts have been pretty unsuccessful. Every calibration I do ends up having lots of magenta, such that blacks and greys on the screen have a distinctive colour cast. I presume this is not correct - it certainly doesn't make photos look very good! I have read about "dynamic contrast" monitors, and apparently they aren't any good for profiling unless you can turn it off. I can't really find any very technical details about the screen, and have no idea whether it has "dynamic contrast" or not. Also, there are no hardware controls for the screen, so I can't really adjust it at all before doing the calibration. Could this be the problem? Alternatively, I know my colorimeter is a pretty cheap model, so perhaps it is just not working very well? Any thoughts would be appreciated. Many thanks, Jon Leighton
