> I've struggled for a decade to understand monitor calibration. I've never really understood it very well, but managed to get by with my old WinXP system with an Eizo Flexscan monitor. I was still getting by after buying a new PC over a year ago with Win7 and moving the Spyder3Pro over. I also bought an NEC LCD 2190UXi monitor and things worked well initially.

I worked with tech support for a few weeks and they could never figure out the problem. So, I've been uninstalling and reinstalling the software each time I want/need to calibrate again. It's a pain, but it has worked for the past year—until this evening.

I've always used the default settings (2.2 gamma, 6500k, LCD monitor, etc. However, when I get into the calibration process and try to complete the step where I match the brightness setting to the number that Spyder3Pro is giving me, I can't raise the monitor's brightness setting high enough to match the given number. This is true whether I select the "Accept Suggested Settings" option or the "Keep Current Settings" option. I've tried both, but hadn't experienced this problem before. The "Suggested Settings" are 90 and 5000k (not the 6500 default I set earlier in the process). I can't adjust my monitor quite high enough to reach the 90 figure. The "Current Settings" gives a 120 brightness figure and I can't come close to matching that.

This is showing up when I cancel a calibration after being unable to match the brightness in that step where I'm supposed to match the monitor's brightness to the number the software is presenting me with. When I cancel at that step and use the BACK button to start the process from the beginning again, that's when I see that the settings have been changed. Is this indicating a problem or is this to be expected? I'm guessing these changes have something to do with my inability to match the brightness during the calibration process, but it's only a guess and I don't know what to do about it. I need some help.
