As Brian says, most tvs advertised as led are back lit lcd/led or led/lcd, the confusion is worsened by these new terms, true and full, however there is led image picture tvs which were initially called true leds, available to the public, see this gizmo article from last year,www.gizmag.com/sony-crystal-led-display/21056/
All the manufactures tune their TVs for a little different look. Go to the stores pick out the picture you and yours prefer also after 90 days or so it wouldn't hurt to have it tuned.
What is having it tuned and where would one get that done?Dave5Cs from Galaxy S III
