Just don't raise brightness more than 1 or touch contrast. Otherwise your grayscale/gamma goes wonky. So essentially chose your white clip point of either 235 or 255 and leave it be. Ultimately from what I've seen from several of this year's models you only need to touch up the grayscale OOTB and you're good to go. It won't be perfect, but it will be good enough that you shouldn't have to fuss with it, especially since fussing with it will probably result in a worse looking picture. Maybe Spectracal will figure out some new stuff with their auto cal and provide a valuable tool for doing the CMS, but OOTB the colorimetry of this years models is already fantastic. If you REALLY want it to be near perfect, invest in an outboard CMS like a Lumagen or a eeColor box.
Thank you for your help! You certainly have a lot of insight on this topic and I respect your opinion. I have these questions, and I am betting they might help others too. Sorry for the list, but I thought organizing it this way would be easier than a run on paragraph.
1) What picture/color mode would you recommend then? user1 with standard color space? or something else?
2) I had read the same about the CMS, but the "Secrets of Hifi" review noted that simply turning the CMS to "ON" and not adjusting anything actually improved things. Have you found that to be true?
3) Is the 4910 CMS worse than the 4810. I was able to on the 4810 to minimize luminance and hue errors fairly well...is this not the case wit the 4910?
4) With leaving contrast alone, as you stated, you clip at 235 or 255....wouldn't 235 be the better choice for better light output. 255 seems like a lot of wasted light!
5) If I run with HDMI standard, can i still leave my player (PS3) set to superwhite on? my thinking is it shouldn't matter one way other the other as long as the player is not remapping values. clipping is clipping and what the player outputs is irrelevant. correct?
6) What have you found with gamma? If I want to aim for 2.3 and then 2.2 at 5-10% do the dark and bright gamma controls help at all? I'm used the the 11 point system where I could tweak more easily.
7) You said don't raise brightness above 1. Is it best to leave it at 0, or does that clip and 1 is actually correct?
Thanks in advance...your help might save me a lot of trial and error calibrating!
