If only it were so easy.  The Kid's TV is an old 60" Sony SXRD rear
projection set... and apparently they do not offer a full pixel option on
projection sets.  I guess it makes sense... the projectors in these sets
are actually 3 seperate 1080p projectors aligned to form one image, to
eliminate overscan you would need to physically adjust focus and realign.
