Kuro 6020: Use 2 Grayscales with PC Advanced

[Dahlsim]

Thanks to the fact that out-of-box movie mode is so close even before calibration to an accurate white point on this display the rise in tempature to rest of the modes is a minor one. Optimum mode is included btw in using the Global Grayscale.

One inadvertent "feature" though I've realized while learning to individually adjust and tweak modes on the 6020 is that PureCinema: Advanced gives you what amounts to a 2nd grayscale memory. All you need to do is switch to PC Advanced you still have your original grayscale. This puts a 2nd grayscale (the original grayscale) at your fingertips. :thumbsup:

This works out particularly well using Standard Mode A/V where you also get separate memory settings for each input. If you calibrate movie mode for instance and want a certain input to use standard mode with the orginal grayscale you should be able to simply set standard A/V on that input to use PC:Advanced. You should get the lower grayscale on that mode.

I have set my Game Mode to use PC: Advanced in fact since though it looks fine with the movie mode grayscale it still performs well with the old grayscale at a couple hundred Kelvins lower.

I would love to see if both memory settings can be saved independantly using ControlCAL. This may simply be an effect offset values kept in memory for Pure Cinema Advanced so this may not be possible but it would be interesting to try.

David Abrams did my pro Kuro calibrations, and unfortunately I do not have meter equipment yet (mainly a time issue). It would be interesting to take meter reading on grayscale, gamma, brightness etc. for each of the A/V modes after a global grayscale calibration to see how they are perform technically.

From avsforum thread (http://www.avsforum.com/avs-vb/showthread.php?p=15762334#post15762334):

I am currently breaking-in my new 5020. I plan on eventually using ControlCal to adjust the settings provided by D-Nice.

The way I read Dahlism's post is that the Advanced Film Mode reverts the back to the grayscale prior to the adjustments made with ControlCal (the out of the box grayscale). Is that correct?


Right. This is assuming you entered your calibration settings using a Pure Cinema Mode other than Advanced.

I assume that is why in D-Nice's Non-Service Menu Adjusted settings he recommends Film Mode: Advanced, but for the Service Menu Adjusted settings he recommends Film Mode: Standard.

My post is really directed to using the Pure Cinema quirk as a grayscale/color temp control rather than for it's intended purpose which is a frame processing control.

This is a fortunate inadverdant "feature" of the 9G Non-Elite Kuro. Combined with the diff temps of the selectable A/V modes, it makes up a bit for the missing color temp control. It so happens that it doesn't really limit your frame processing choices much either.

The easy way I find to think of it is simply as 2 different Grayscale memories, one for Pure Cinema Advanced and one for the rest of the Pure Cinema Modes. (In reality I'm not sure it's implemented that way, but for our purposes it appears to work that way).

So if you calibrated for Pure Cinema Standard but want to handle frame processing using Pure Cinema:Off or Pure Cinema:Smooth you will still be using the same grayscale. It's only if you switch to Pure Cinema:Advanced that you're getting a different grayscale.

Combine this with the fact that each A/V mode remembers it's own Pure Cinema setting and you have some added flexibility/adjustibility using the Non-Elite selectable video modes.
