So I checked this one out today at Sam's and the design of the back panel would seem to indicate a Full Array Direct Lit LED backlighting scheme.
I didnt like the off axis viewing, which seemed to dim rather quickly.
There is no Optical Digital Audio Out. It is a SPDIF Coax Digital Audio Out.
There is a 1/8th" Headphone out jack.
There is no Audio Input associated with the VGA Input.
There are separate Component and Composite inputs but they share the same RCA Analog Audio Stereo Inputs.
Hope that helps.
Ill pass on this set and do not plan on recommending it. Too many odd things about it.
