SOAP OPERA EFFECT: Ignore this!
Why?
The so caled soap opera effect is caused by creative frame interpolation (CFI). Almost all manufacturers have a different name for it, but they have two things in common. First, the more CFI which is used, the more soap opera effect you end up with. Second, you can turn down, or off completely!
People tend to be stupid about this and not realize that you can just turn off CFI if you don't like it. I've gone into the Sony store and told them that I hate the look of their CFI. It is unnatural and makes their displays look lousy. The guy disagreed with me... But, he was stupid. Like I said.
Some people like it, some don't, so it's a personal choice and IS a choice since you can control it.
I will restate: The Panasonic plasma I listed will provide a better image than the LG will provide, and Panasonic has a failure rate that is about 75% lower than LG displays. So, IMO, it is worth it to go that direction.
I personally would never recommend LG due to their serious reliability issues, but if your intent is to get one, then I strongly recommend that you get a warranty for as long as you intend to own the display because I personally know half a dozen people who have seen catastrophic failure of their LG displays.
Sony and Samsung have average reliability, but have some great looking LCD screens.
Panasonic has the highest reliability, and their plasmas are second to none, but Samsung plasmas look great.
Since you are most likely going to end up with a glossy screen whether it is LCD or plasma, I will ask again...
Is there a specific reason why you aren't looking at plasma?
In my experience, people don't buy plasmas because they don't realize that plasma produces the best image of all the display types. They think LED backlit LCD displays do (they don't). So, they pay more, and get a lower quality image.
