Una pequeña diferencia entre los dos pdf's es sobre el 3D. El HD25 pone que es compatible con nvidia 3D visión. Sin embargo en el del hd131x no pone nada al respecto, pero usa la misma tecnología que el hd25, así que es posible que sea información omitida.

En teoria mañana Worf presentará su review donde esperemos que hable del 131x.
