| 82 | help | |
| 83 | This can be used to adjust the minimum FCK/PCK ratio. | |
| 84 | ||
| 85 | With this you can make sure that DISPC FCK is at least | |
| 86 | n x PCK. Video plane scaling requires higher FCK than | |
| 87 | normally. | |
| 88 | ||
| 89 | If this is set to 0, there's no extra constraint on the | |
| 90 | DISPC FCK. However, the FCK will at minimum be | |
| 91 | 2xPCK (if active matrix) or 3xPCK (if passive matrix). | |
| 92 | ||
| 93 | Max FCK is 173MHz, so this doesn't work if your PCK | |
| 94 | is very high. | |
