Depending on your willingness to invest in the set the correct answer to dramatically improved the image on the 82740 is to properly calibrate it using external color management via either a Radiance Lumagen or an EEColorbox and something like ChromaPure or SpectraCal. Once you do that you have a totally different television. You will do it in Bright... Brilliant worthless for anything resembling accurate color. You can have a bright snappy picture with dead spot on color.. That is hopeless with any of the preset modes or in Advance Mode. The CMS is not linear.. external color 3D Color Look UP Tables are required. The EE Colorbox is about$700 a pro can do the calibration and you don't have to buy a meter and software. The Colorbox will correctly set 4000 plus colors and interpolate to near perfect anything in between 4000. This kind of image is not available on your Sammy without an external color management processor either. In fact just about any display needs such a device to get color right. Some pro monitors have a similar capability built in. Pefect color/Perfect Tint may be the name for the CMS in the Mits but it is just crap, totally crap. I spent 3 years messing around with an 82837 then the 92840. I bought a Radiance XS and ChromaPure automatic and magic astonishing color... The XS is no match for current Lumagens or the EE Color... but you can still get color to an error level dE 1 or so on average... A pro with a high end meter and a late Lumagen or EEColor could get it to nearly dE of zero. The lamp needs to be on bright btw.
I don not plan on investing in any calibration equipment, but had a question about a point you made...are you saying that "Bright" pic mode is a better starting point than "Advanced"? This is the first I've seen this mentioned, so I wanted to confirm.
I'm assuming to get this incredible picture you describe, not only would a person need the equipment you mentioned, but the knowledge of how to work the service menu...correct? What I'm asking is - if I switch my TV to "Bright" mode and mess with the contrast, brightness, color, etc. I'm not gonna just happen across the perfect balance, am I?
