One thing I definitely do not agree with is how you guys are doing your backlight. Any numbers I have put in and any of my own calibrations has never worked out with the backlight less than about 70-80. I don't know what you guys are seeing with that so low but I don't see it in any of my real world tests whatsoever. It always in every single instance makes the picture too dark to call it reference by any means. How are you supposed to realize real world photographs and such when your backlight doesn't allow you to produce natural sunlight and the bright sky? I guess if you cannot handle it for long periods it makes sense.
Anyway, I am having troubles. At the http://www.lagom.nl/lcd-test/
site I am running into a problem with ANY numbers that I input into ISF. The problem is that there is ALWAYS banding on the gradient test and immediately when I switch to any other mode BUT THX the banding COMPLETELY DISAPPEARS. What the hell is going on with that? I can also say with fact that the ISF modes indeed wear off on each other. After inputing a 10 step calibration I immediately noticed a pinkish haze in the gradients that wore off on my other ISF calibration. Extremely weird to say the least. Anyway, would it be possible for anybody with a calibrated set to go to that site and test your ISF calibrations against the homegrown ones on this set. I will be inputting more of the sets I see on the set before I go back to my own or use natural! Yeah, you heard me right.
On my April 2010 build Natural is almost perfect. I have no idea why but it hardly takes any calibrating with the limited tool set you are allowed to match colors, or gamma, or whatever. The only problem I have in general is that Edge Enhancer is locked on and you have very limited color tools. Why and the hell would they lock edge enhancer on for all their homegrown inputs?
I would be grateful if anybody can check the lagom site out for me and report back details. My set is a truly beautiful one and was night and day from the one I switched back. There is no dirty screen, no pixel problems, nothing. The thing is beautiful in every sense but damn does it take a lot of computing to find the sweet spot.
