A:Answer Hugh - The type of wall mount you utilize will ultimately depend on what your preference is, and if you'd like your TV to move/tilt or stay in a fixed place. In comparison to the TU8000, the AU8000 features Dynamic Crystal Color, Mega Contrast, Motion Xcelerator, Samsung Health, and PC on TV functionality. The AU8000 also features Q-Symphony, Object Tracking Sound Lite, and Adaptive Sound to improve your audio experience. ^Gina
