Without futher ado, here are my settings.
Dynamic Contrast OFF
Static Gamma -4
Color Temperature WARM
B DRIVE -4
G DRIVE -13
I first set my service menu settings to match my friends newer TV. If you play with the BRTC, COLC or UVTT register, remember to set the registers for all of the resolutions, inputs and aspects that you will be watching. Those registers seem to be stored individually for many of those variables. Also the COLC register needs to be set one count higher than the desired final setting. Seems like a bug in that register only.
At the 10% luminance level with all of the CUTS set to zero, my TV produced a very high Blue level, a middle Red level and a very low Green level. I kept the Red Cut the same lowered the Blue level and raised the Green level. The result was a near perfect 65K at 10% with a delta e under 2. My 65k jumps higher at 20% luminance becuase of a hump in the Blue output at that level, it then goes back to 65K with delta e's under 2 at 30% to 80%. At 90% and 100% Red drive drops off a bit, so my delta e's approach 4.
Notice that this calibration is for a backlight level of 20. My meter noticed a very small difference between backlight 20 and backlight 0 for a full black screen. For values above 20, the black level rose a bit with each click. I have a light controlled room, so I am trying this backlight setting and enjoying it.
Contrast has been raised to 98 when I have such a low backlight to conserve all of the light available. The meter showed a contrast ratio of over 2000:1 with those settings.
For color, I used the tint control to put the cyan and yellow right at their optimum values. I then turned on Colormaster and raised the Magenta saturation to offset the very high saturation of Green on our machines. The result is that the crossing lines for Blue-Yellow, Cyan-Red and Green-Magenta all cross exactly where they should at the 65K mark.
I have been watching these settings for serveral days now and I like 'em. And the meter is happy too.
