Really quickly, if i may, I'd like to chime in on the "color" issue.
AVSforums have gotten more and more popular as people find out about what an amazing resource it is. As prices drop and HD becomes more accessible, the numbers of people wanting to get involved in this crazy hobby of ours increases.
That being said, one of the reasons avs exists is becuase it is a place where experts and laymen can come together and discuss the finer points of Audio Visual Sciences.
The goal for a long time on these forums was to find out how to get the most "accurate" images and sounds from their equipment. That is why you will see people obsessing over what units do the best jobs at decoding different sound sources, and why people obsess over color.
It used to be (and seems like less so now) that most people here would pay 300-600 dollars to have an ISF calibrator come to their home and spend hours working on their displays to get them to perform as close to "accurate" as possible.
The goal was to have this "televisions" show exactly what the directors intended.
Now, especially with this panasonic unit which is A) cheap enough and accessible enough to many people and B) accuratly calibrated OUT OF THE BOX on color 1 mode, those people who are looking for that accuracy are very happy. Most of the people on this site used to settle for nothing less and pages and pages on this forum were devoted to achieving those goals.
That being said, after an ISF calibrator worked on the sets, they often had reduced light output, lowered blacks, and overall less "pop"
One of the reasons for that was that our televisions are capable of more color and more range than the film sources and movie theaters are. So much of that is toned down.
Furthermore, some people don't care as much about the "accuracy" of the image. Perhaps they are less interested in films and the shots and moods that the directors intended and are more interested in say, television, sports, gaming, or an accessible and enjoyable vieiwing for their friends and families, perhaps even with some ambient light (which was a complete no no for a long time).
There is no RIGHT answer. People saying Color 1 and ONLY color 1 should be used, really are not being fair. If you want to see movies EXACTLY as the directors intended, and that is your primary goal, then they are corrrect. Use color 1.
If, on the other hand, accuracy is less important than enjoying a bright, more saturated image, especially on sources other than films, by all means, enjoy the other settings and tweak them to your hearts content. That is why they give us all of those options.
I think its a wonderful thing that we are even able to purchase a unit that has perfect color and calibration for movies out of the box, but then with nothiing more than changing the preset setting, are able to boost light and color for watching football or playing games.
you dont have to choose one setting and keep it there!
Thats my two cents and i hope it wasn't insulting to anyone or too much of a repetition of whats already been stated, but if it was insightful to even one person, i'm glad to have posted it.
Be well and enjoy!!! Its a fun hobby, no?
