Let me start with a little background. I've been a long time user of the Colorvision Spyder for my PC. I do a lot of photographic printing and use the Spyder as part of my calibration process. So I've become very familiar with color temperature, CIE charts, color workspace, gamma, etc. I also have a 36" Sony CRT that I've adjusted trying either Avia or (the original) Video Essentials. So I went and got the SpyderTV and Spyder2PRO upgrade - not only for my photographic work - but in the hopes that I will be able to tweak my set a bit closer to standard.
One of the first things I did when I got the TV was go into service mode and write down the value of every single setting. I'm an electrical engineer by trade so I usually dive into the lowest detail of anything I wind up buying. I also appreciate not changing anything until I have the tools and the understanding to do it.
My DVD player is hooked up to the Sony Video4 input (component). In looking at the service codes I see there are separate Drives and Cuts for the Video4 input. No problem. But then I also find that there is another set of separate Drives and Cuts for "Warm Color Temperature Offset". Now that got me a little confused. I am in fact using the "Warm" setting for Video4, so which Drives/Cuts should I use when calibrating?
And while I've read many of the threads here over the last few months (yes, I tend to plan things out), there are some practical concerns that I haven't been able to get the clearest handle on. So I have some more questions about calibrating a CRT TV:
1) In general, is it better to calibrate the primaries before the greyscale, or the other way around? (edit) Ignore this question, as Chris straightened me out about CRTs not having primary adjustment controls.
2) When using a measuring device like a Spyder or EyeOne on a TV, I assume it's better to set the "standard" controls (the ones normally available from the menu) to the center position just as a matter of good practice, and then use the Drives and Cuts in service mode to make the adjustments?
3) I've read http://www.avsforum.com/avs-vb/showthread.php?t=531494 , and there's a ton of great info there, but one of the recommendations is to go into a calibration process with SBRT set to 31, which is the max. Is there a consensus on this?
4) Related to 3, is it better to use the standard menu options to set the Black and White points, or is it all best done in the back and forth relationship of the service codes?
