if you can control ambient light option 2 and 3 for best overall pq. if you can't the sharp would be the winner. the lg is junk in every way possible.
I vehemently disagree with this uneducated statement. The LG 65LW6500 is a fantastic tv that consistently gets excellent reviews. Head over to the official thread for more info. OP, you would be very happy with the LG or any of your choices, as they are all good in their own right. I will say this though. If you are prone to the rainbow effect on DLP's, do not get a plasma. It will drive you crazy with the trailing and headaches. Yes, actual experience.
I have not yet seen a passive TV that has a gotten a really good review for 2D content. If there are any please post a link to them.
Samsung D8000 sets seem to be in short supply, apparently the E8000 sets are already in production and will arrive in about a month.
