Well your homie needs to do his research, theres alot of people who sell tv's out there who dont know shit.. like when you hook up your coaxial cable tv, i asked if they had quad shielded cable.. they looked at me like huh? i explained to them that regular cable is weak especially when you are running it next to power you get alot of interference, therefore quad shield eliminates all that.
The TV with the best picture came out to be a Panasonic actually, after doing 6 months of research
In this exact order, Panasonic, Sony/Samsung, Sharp, LG, Toshiba, Mitsubishi to me atleast.
