en la review de la ST30 David Mackenzie pone que prefiere la ST30 en condiciones normales de luz o durante el dia debido al panel “Infinite Black Pro”, y en cambio, para salas oscuras sale mejor la G30.

"Despite the fact that its pictures were slightly less accurate than those of the Panasonic TX-P42G30 (Panasonic’s highest-specced 2D-only Plasma this year), we preferred the ST30′s images during daytime viewing. The reason for this is the “Infinite Black Pro” branding, a marketing phrase that Panasonic uses to refer to a high-performance Plasma panel which features an ambient light rejecting screen coating. In a pitch black room, the G30′s extra accuracy would result in technically superior picture quality, but in most normal viewing conditions which have some ambient light present, the inkier blacks displayed by the TX-P42ST30 thanks to its screen coating sway things in its favour. Accurate Greyscale, Colour and Gamma are all important in determining picture quality, but Contrast is of critical importance."
