Did "57" (whom I do know about, same as Hugh from digitalhome still, correct??) use a totally dark room? Its always best to do in darkness to reduce light bleed. OH and the TV needs to be properly warmed up usually...around 3-4 hours if I recall before you start any calibration.
When I started my calibration, I removed all of the ambient light with curtains and shades. I would use various colour grades ramps, and screen calibration stills from the application I used, HCFR (
http://sourceforge.net/projects/hcfr/), and spent a good week reading the FAQs and forums on how to properly use it. I used a notebook to capture and interpret the data with my iDisplay 2 from X-Rite, used another computer to show the images from blueray disk, then used my PS3 HDMI also and calibrated that. I had to go into the ADVANCED section of my TV...and adjust the colours individually, and something else....truthfully I forget now...it was maybe saturation and then brightness? Funny thing....none of the setting ever where the same after each test....once I hit a perfect sweet spot...then I tinkered some more....and could not get back to the previous level....oh well.
Sorry, I did not say "57" was not a PRO, the reference was to anything from BB or FS...seeing they use just the cheap tools, and non professionals....IMHO.
My projector was calibrated by William Phelps...he was considered one of the best in North America (he was so in demand with the vendors it was hard to get a small projector like mine completed, i said take your time which was around 4 weeks before he could start)...maybe even the world. I know my calibration took around 2+ days in his Lab in california. LCOS exhibit a particular bluish tone from the panels, so using filters, you can remove it, and extend the contrast ratio. Needless to say, its a 14 year old projector...that I will still use!!! Oh am I have a prismasonic anamorphic lens in front of the projector.
I think that calibrations are always needed....but just depends on the extent or level you want to achieve....I wanted the best ...but now I have to start all over
