Luminance False Color
The Luminance False Color display replaces pixels that fall within a specified range of
nits or stops values to a color that you specify. Up to 9 configurable ranges can be
defined. For example, you can use the Luminance False Color display to tag pixels that
are within a specified HDR range.

The false color ranges are defined in nits or stops depending on the gamma curve set
up in the input (select Settings and then Input). If a camera-based gamma curve is set,
such as S-Log2, the false color ranges are in stops. If a display-based gamma curve is
set, such as SDR Narrow, the false color ranges are in Nits.
These controls adjust the Luminance False Color display:
Meter Overlay
Set to On to enable the Meter Overlay in the Picture application. The overlay shows the
false color definitions in nits or stops made in the Luminance False Color table at the
bottom of the menu. The overlay can be moved to the right, bottom, left, or top of the
image by dragging the meter with a mouse or by touch.
Default: By default, the false colors are defined according to the BT.2408 specifications
if a display-based gamma curve is set for the input, or a typical camera specification if a
camera-based gamma curve is set for the input. If changes are made to the false color
