I've just hooked up my Wii U to my 46PFL9706 via an Onkyo TX-SR608 amplifier.

I'm reading a lot of stuff online about the Wii U graphics being washed out due to it outputting limited range RGB (RGB 16-235, rather than 0-255).

Many online sources suggest adjusting the TV'S 'HDMI black level' to compensate.

What would be the equivalent setting to alter on my 46PFL9706, as there is no 'HDMI black level' setting?

Or is there a better way around this issue?

Many thanks,
