4.5.10 Shoulder - White Stretch / Compression
With Shoulder - white stretch/compression -, the contrast in bright picture areas can
be either enlarged or reduced. Four different characteristics according to the dia-
gram in figure 429 are selectable. Unlike Master Gamma, dark picture areas are
less affected by this adjustment. Note that white stretch does not lead to any clip-
ping of highlights (luminance levels above 100%).
1. To use shoulder - white stretch / compression, select menu Color, submenu Pri-
mary
2. To select Shoulder parameter slide directly on the touchscreen or use the cor-
responding digipot
