6.5.3 Ramp
Each time you press RAMP, the ramp type switches between Ramp and Deep Color Ramp.
The ramp types that can be transmitted vary depending on the output format and aspect
ratio (see Table 12-2, “List of output patterns”).
Ramps are used to adjust or test linearity, adjust gradation, and so on.

Deep Color Ramp
Deep color ramp patterns are transmitted from the HDMI connectors on the LT 450 and
its installed options when the output format is 1080p/59.94, 1080i/59.94(30sF),
1080i/50(25sF), 720p/59.94, 720p/50, 480p/59.94, 480i/59.94, 576p/50, 576i/50, or
VGA(640×480).
Deep color ramp patterns are transmitted in the following order: 8 bits, 10 bits, and 12
bits. To transmit a deep color ramp pattern, set FORMAT to 4:4:4 and BIT WIDTH to 10
or 12 as explained in section 8.8.2, “Configuring the HDMI Output.” (When BIT WIDTH
is set to 10, the 12-bit section is displayed using 10 bits.)
Because all the gradations of the deep color ramp pattern cannot be displayed in a
single line, the pattern is displayed over multiple lines. The number of lines used
depends on the output format as shown below. (See the figure above for an example of
the deep color ramp pattern when the output format is 1080i.)
