I have used the Colorvision Spyder system (with the OptiCal software package) for my CRT monitor. I recently converted to a ViewSonic VX2035wm LCD monitor, and went to calibrate/profile it.
In reviewing the User Guide. I see it said that the PreCal function and the Precision mode of calibration are not applicable to an LCD display. (Funny that when I set the software control panel to "LCD", it doesn't disable those things!)
Operating with the Standard calibration mode, the on-screen instructions say to set the monitor's Contrast and Brightness controls to the factory defaults. Just for kicks, I did that. (Lost various housekeeping settings that way, but oh, well!)
With the Standard mode of the OptiCal software, I had no chance to set a target value of white luminance.
The calibration/profiling process went smoothly. When everything was done, the software reported that I had a white luminance of about 190 cd/m^2.
I understand that the optimum white luminance for reviewing images varies with the luminous envronment, but that something in the range of 80-120 cd/m^2 is probably reasonable for "general" use.
After this experience, I left the software set to "LCD" but in fact used the Precision mode, set the target white luminance to 120 cd/m^2, and went through the process again. Everything seemed to go well. (I couldn't get the black luminance up to the value initially recommended by the software - 0.36 cd/m^2.)
How should I react to this chain of events? What do I need to know about these curious things?
Thanks.
