These features are a bit like screen savers
only they can actually 'rub out' screen burn. Please be aware however
that it is still easily possible to cause irreversible image retention.
'Signal Pattern' and 'All White' are however fantastic tools.
'All White' is great for checking to see if you have got any screen
burn as it shows retained images very clearly. It is also the quickest
way for removing minor screen burn. Quite simply when you select 'All
White' the screen goes.. well.. all white. This is simple but very
effective.
Signal pattern makes a pattern of black and white repeatedly across the
entire screen. This is slower then 'All White' for removing screen burn
but if you have been caught out and got a nasty bit of image retention
then a good blast (perhaps an hour or more) of 'Signal Pattern' might
reduce or even remove it.
The built in protection features of a TV are not a replacement for
precaution and I definitely still recommend turning down the
brightness, contrast and colour when you set up the TV. These features
are however extremely useful. So much so that I would consider that
they are top of my list of requirements when choosing which screen to
buy.
