One thing you have to know about the AVSforum (and the main reason most people avoid it) is everyone nitpicks things to the point of ridiculousness.
I have literally seen 30 pages on something, where someone takes a TV displays something like a greyscale or black background, messes with all the settings like contrast/brightness to a point where the TV really isnt watchable, and then they notice an artifact and complain that their TV has a major problem, when it is pretty obvious the person was just trying to find something wrong, and they noticed some weird effect they practically forced the TV to have.
My personal favorite is people who have antialiasing (clear-type is default on Vista) on fonts on their computer outputting to the TV at native resolution with no overscan then claiming the TV's colors bleed. They claim this because a red font on a black has reddishblacks around the letters and isnt crisp, so clearly the image must be bleeding, and the fuzzyness has nothing to do with the filter that they have on all fonts in their computer. And yes, specifically antialiasing's job is to make it bleed so its easier to read by appearing round, thanks idiot, the problem is on your end, but we needed 40 pages on the "no overscan bleeding problem" you found.
Sharps have banding, Samsungs have purple haze or a halo or something, Sonys have huge huge smearing issues, Pioneer TV's buzz, Toshibas are green pushing, Westinghouses Green crush, Vizios sell crystal meth to their neighbors, Phillips TV's ate their kids........ lol What people don't mention is that typically these problems are isolated to someone looking for them *and* if it is a real problem, Samsung, Sharp and whatnot are pretty good about replacements.
Also you need to keep in mind the that people tend to post (especially at AVSforum) when something is wrong, and then they follow it up with 900 posts on the topic and try to sound like a chorus of people to ensure they get noticed. When someone loves something they post once or twice and leave it be.
