RE: Re: TV Recommendations?

["Neil Ball" <neilball@xxxxxxxxxxxxxxx>]

The backlight settings can be thought of like a dimmer switch for the
backlight intensity - the backlight is needed as LCD is not
self-illuminating unlike plasma cells, therefore without a light source to
shine through the RGB arrays the picture would be black. Exactly how the
backlight works depends on the TV - some models simply have a uniform
backlight so adjusting its level simply makes the entire source for the
screen higher or lower. At higher settings the screen will be brighter but
this can have an adverse effect on black levels. Other screens (usually
using a direct LED array rather than edge-lit) use local dimming of the
backlight too so that if that area of the screen is meant to be dark then
the backlight can be automatically adjusted to improve the appearance of
dark scenes.



When you take a look at any TV in a shop environment you are likely to find
it is in "shop" mode with all of the settings maxed out to make
the screen
as bright as possible under the often very bright shop lighting. This makes
it hard to really assess how well the screen might perform in your living
room! You'll only find properly set up screens in specialist AV dealers
demo
rooms but they will not have several models set up to compare.

One more question....
I had a quick play with an LCD TV with edge lit LEDs and it has setting for
backlighting, contrast and brightness.
Contrast and brightness speak for themselves.
But what effect on the picture does adjusting the backlighting setting? (It
was on 100%).
Does it effect the contrast under certain conditions? e.g. night scenes?

Thx
Andy
