Sharp LC-LE745U picture settings

Calibration report using these settings:
Below you'll find the settings I found best for viewing the Sharp LC-60LE745U in a dim room via the HDMI input. Your settings may vary depending on source, room conditions, and personal preference. Check out the Picture settings and calibration FAQ for more information.
Calibration notes: The Movie mode delivered the best presets but its grayscale was too bluish. While I was able to correct the grayscale to a large extent using the 2-p[oint system, the more advanced controls, namely the color management system and the 10-point grayscale, didn't function well enough to use to improve the image further.
When I first set it up using test patterns, the color management system seemed to work beautifully aside from one major flaw: a blue test pattern caused the TV to dim, making accurate measurement of blue impossible. The TV brightened enough for an accurate reading when fed a higher stimulus than the standard 75%, but it wasn't consistent so I ended up not tweaking blue at all, despite its poor readings and results on my charts.
However, once I exited the calibration process and looked at program material, it was clear the dimming in blue wasn't the only issue. The image looked overly saturated and too red/blue despite solid readings on my charts. Long story short, I decided to zero out all of the CMS controls and ignore it for this review/calibration. Note that the CMS controls on the 640U worked fine.
Trying out the 10-point grayscale system, I noticed large light output difference when menu was up, making it tedious, and adjusting one "position" (IRE point) mode affected another quite a bit. I also found myself having to increase the backlight control to keep light output consistent during the course of adjustment. Those issues made the small gains of using the 10-point system not worth it, but on the plus side my results using the standard 2-point system were very good.
I did not publish a calibration results chart with this review, and the Geek Box readings for gamut are not available yet. That's due to a labs hardware issue; my AV Forge signal generator failed before I could get correct readings. I'll upload and attach the chart and update the Geek Box with gamut readings when the generator returns from repair.
Update June 13, 2012: My equipment has been repaired and so I have added the calibration results chart and modified the Geek Box results accordingly.
