No reviews anywhere online (albeit a very short and undetailed one on Vizio's website). Also OOS on Vizio's website. Be wary, this might be some defective model that Vizio has chosen to discontinue.
This is a reply to myself. I realized that the OP actually made an error in typing the model number. It's actually M3D420SR (makes sense if you think about it, its a 42 inch TV, not 40.) and that's actually the model number on vizio's website.
