It's not surprising that Vizio does not reveal this information on their support pages (LOL). In this case I suggest asking the pros @ AVSforum.com. Very helpful in this type of situation IME and O>
Does the VIZIO M601d-A3R 60-Inch have the same type of semi-gloss panel as the VIZIO M551d-A2R 55-Inch. The 65" inch panel in this series is supposed to have a full glossy panel. I just wanted to make sure that the 60" and 55" inch both have the hybrid glossy/matte finish vs. the full gloss on the 65". Can anyone answer that question? According to CNET, "Vizio also mentioned that, like all of its 65-inch passive 3D TVs, the 65-inch M651d will have the glass pattern retarder finish, which results in the glossy screen we like the M3D651SV. The other 3D sizes will have a matte or at least semigloss film pattern retarder, like the M3D0KD, while the smaller non-3D sets will be straight matte. Anyone with knowledge please comment.
