Please Help with SXRD "Advanced Settings" Values...

[ClinicaTerra LTD]

Hello, Forum!

If there is anyone with any knowledge or in-depth understanding of Sony's SXRD Grand Wega HDTVs, I would appreciate you taking the time to perhaps lend some insight to these questions I have regarding the operation/modes of my KDS-50A2020 model...

Like I said, my model is the 50" KDS-50A2020 in Sony's Grand Wega rear projection line; the set offers three picture modes: Vivid, Standard and Custom (this is not one of the Sony displays that offers "Pro" or "Cinema" modes...). Now, most enthusiasts, videophiles and even professionals would of course state that "Custom" is the preferred mode for a super-accurate picture, what with its "Warm 2" color default and overall access to massive tweaking...but going back and forth with a calibration disc and making settings in both the "Standard" and "Custom" modes (I didn't bother with the Vivid mode even though the colors are pleasing) it seems that the characteristics of "Standard" looked the best with the most "punch" -- also, the "Custom" mode opens up an entirely different "Advanced Settings" menu that just confused the heck out of me; my train of thought was Standard mode was a good compromise between Vivid and Custom, without the needed extra tweaking that's required in Custom, and so I calibrated with a "DiscWasher" calibration DVD in Standard mode. Believe it or not, the settings I settled on, based on the test results, really weren't that far off Sony's default settings...

In STANDARD mode, values came to this after calibration:

Advanced Iris: Auto 1

Picture: 80 (the voice-promoted calibration system I used claimed that I should "reduce contrast to approximately 80 percent of maximum and stop..." so I left the Contrast/Picture at 80 because Sony's default value for this setting was 100 which seemed too high...)

Brightness: 53 (Sony's default for this was "50," but the calibration system noted that at "53" is where the Pluge Pattern dark bar dissapeared and barely showed -- so I left it at 53...)

Color: 50 (Sony's default of 50 seemed fine)

Hue: 0 (Sony's middle default position for Tint/Hue seemed correct at "0" too)

Color Temperature: Neutral

Sharpness: 50 (this was a massive pain to set -- no matter which test pattern disc I used -- the DiscWasher or the THX Optimizer -- the sharpness didn't seem to change either way. I am connected via HDMI to this display, and I have been told that some HDMI connections don't really change the sharpness on a display at all, so I don't know; what I DO know is that Sharpness did not seem to increase or decrease on the test patterns so I just left this at Sony's default of "50"...)

Noise Reduction: Low (not sure if this should be Off or not, but Sony's default of Medium is what it goes to in Standard mode)

That's all the settings for Standard mode -- now, under CUSTOM, these same adjustments can be made, plus an extra menu called ADVANCED SETTINGS, and this is where I would need help...I just ordered a DVE "HD Essentials" Blu-ray calibration disc, as a Blu-ray player is feeding this screen through an Onkyo receiver, but if I decide to recalibrate under Custom mode once I get this disc, I would need help adjusting these controls that open up under Advanced Settings:

GAMMA (I was told this should be LOW for better shadow detail)
LIVE COLOR (I was told this should be OFF when using Warm 2 color temp)
EDGE ENHANCEMENT (I was told this should be OFF)
DETAIL ENHANCER (I have heard everything from leave this OFF to use the MAXIMUM setting for Blu-ray discs to really pop off the screen...but which is it?)
WHITE BALANCE (this is the most difficult setting to make -- there are Gain/Bias adjustments here for all color parameters, but without tools, these can't be set right; would it be okay to leave these on Sony's default of ZERO (0)?)

...can someone perhaps guide me in the right direction in terms of which mode to use and if I do recalibrate in Custom, how I can set these Advanced Settings?

Any help would be greatly appreciated.
