We have a Panasonic plasma display (TH-50PF9UK). Just recently I noticed
that the monitor is doing something similar to AGC although AGC is turned
off in the menu. When the picture is darker it boosts the light output and
when it's brighter it lowers the light output. Toggling AGC on/off does not
seem to affect the picture at all.


I spoke to tech support and they said that this AGC-like behavior is built
into the monitor and they knew no way of bypassing it. Does anyone know a
hack that will bypass this behaviour?  Or, does anyone know how to get into
the system menu?
