This can be used to adjust the minimum FCK/PCK ratio.
|
|
|
|
With this you can make sure that DISPC FCK is at least
|
|
n x PCK. Video plane scaling requires higher FCK than
|
|
normally.
|
|
|
|
If this is set to 0, there's no extra constraint on the
|
|
DISPC FCK. However, the FCK will at minimum be
|
|
2xPCK (if active matrix) or 3xPCK (if passive matrix).
|
|
|
|
Max FCK is 173MHz, so this doesn't work if your PCK
|
|
is very high.
