Hi, I've been trying to calibrate my Dell laptop with Windows XP using my Spyder 3 Pro without any success. After running the calibration process, nothing changes. The laptop screen is still too cold, and running CheckCal shows that the gamma is still too high at 2.8. There is no Adobe Gamma on it. However, on my Lenovo laptop with Vista, calibrating it resulted in the screen being a lot warmer (and correct). Does anyone have any ideas why the Spyder software doesn't seem to be able to override whatever Windows XP has on my Dell? Thanks in advance
