OpenSPA: of course that source (a users forum!) cannot be considered reliable.
The typographic font used in the table is very rough and clearly not Vu+ original...
As you can see, the people that manually compiled that summary ERRONEOUSLY SWAPPED these 2 contiguous values for the Zero:
3D = No (absolutely wrong, all receivers can output 3D video signals!)
PiP = Yes
while in the official Vu+ summary:
3D = Yes
PiP = No
So, you could ask for a reimboursement to the author of that deceiving summary...
I have already posted the Vu+ official source:
