What is the difference between the LMD and LXD models of the Pansonic Viera?
LMD and LXD refer to LCD models, not plasmas. The difference between LMD models and LXD models is in the direction of the ultra wide viewing angle. This is horizontal in the case of the LMD and both horizontal and vertical on the LXD models. Whether this is important depends on the situation of the set in relation to the viewers. In a normal living room situation you may notice little difference, but in some circumstances it could be beneficial to have the higher specification LXD, at higher price.
