rear projection tv's are the ones that are deep & have 3 foot of workings underneath them, LCD rear projection tv's are not a lot bigger than a plasma, we had a 42" sony LCD rear projection & it was fine, but you get used to the size after a while so we bought the same T.V. but in a 50"
the deepest part of it about 40cm, including the base stand it has about 20cm from the bottom of the screen to the cabinet it sits on.
