Hi all. Need a little assistance. I am considering buying either the Mitsubishi 52725 or the Samsung 5674 (whenever it comes out, if ever). My wall unit is going that I must put the TV set in will require the set to be placed at height that begins at 40 inches. I will be sitting in a couch that is about 12 feet away that will but my eye's at about 40 inches. Accordingly, since these sets have a based of about 6 inches or so, the center of the screen will be approximately 18-24 inches above my eye level. Is this going to be a problem? Will there be diminished Picture Quality or is this difference not substantial enough. Help. Thanks
