EH model is side lit and thinner and, according to images online I have seen, has an audio output.
FH model is back lit so is thicker, to the tune of almost 4" and does NOT have an audio output of any kind whatsoever.
This is not a problem IF you route audio through a receiver or prefer to keep things simple and use the TVs onboard speaker. Which in our case do sound quite good in our TV room.
