If you are interested in the nitty-gritty of HDTV projections sets, this article is for you buddy. This is Extreme Tech's round two of their LCoS Shootout where they go in detail about the testing. And let me tell you, they did extensive testing.
Before they just shoot numbers at you, they explain in full detail
what and why they are testing it. For example, they explain the brightness level and why it's set so high when it comes
right out of the box. It is, of course, because of the sales floor and making it stand out from the other TVs.
Take some time (15-25 mins) and read over this article.
