The graphics below show the relationship between the LEDs reaction to real time video on the
screen, this is called “Local Dimming”.

The areas in the picture on the left shown by A, B, C and D show the dark areas of the screen.
The picture on the right shows the backlight LEDs. Note they are dimmed out in the same area
as the dark video on the left.
To see a representation of the “Local Dimming” the TV has to be set to the “Store Mode”.
Note: These graphics are from the 47LG90 which has more LEDs than the 42LH90,
but the explanation remains the same.
