Depends. I go to the movies on an almost weekly basis (depending on if there is anything good out). Does that make me hardcore? I doubt it. Just someone looking to have a good time.
Yes, much more for best picture quality. There are other things that can be changed to bring the best picture out of your set. The default picture settings are usually horrible in terms of picture quality, bulb life (rear projection sets) and overall longevity of the set. All sets have a "hidden" service menu where these settings reside - things that go deeper than contrast, sharpness, black levels etc.... I recommend getting an ISF certified calibrator to mess with these settings. One wrong move and your TV is a large weight.
You could also get a calibration DVD that shows exactly what your contrast, sharpness, tint and o. Something like "Digital Video Essentials" or "Avia".
Possibly. But then again, so are a lot of casual gamers. They don't know any better to know it should be different.
I don't know. I've bought an air intake for my car, but I wouldn't call my self an enthusiast. Just someone messing around really.
Definately. We could debate until our hands are bleeding, but it's really not worth it as it won't change anything. Plus we've gone more than off-topic with this thread. I'm partly to blame for this going way off topic so sorry about that.
So sorry guys, but this one's run it's course.
