This command is used to specify an offset to the horizontal and vertical position of the displayed image.
A positive horizontal offset will move the displayed image to the right, and a negative horizontal offset will move the displayed image to the left. A positive vertical offset value will move the displayed image down, and a negative vertical offset will move the displayed image up.
If the requested offset requires the image to be moved beyond the bounds of the display area, part of the image will be cut off.
The horizontal offset is limited to ±10% of the input horizontal resolution, and it must be a multiple of 2 (..., -2, 0, 2, 4, ...). The vertical offset is limited to ±50% of the input vertical resolution, and it must be a multiple of 4 (..., -4, 0, 4, 8, ...).
Additional detail on bezel adjustment can be found in Section 5.1.6.
Write Parameters
| BYTE | BITS | DESCRIPTION |
|---|---|---|
| 2:1 | 15:0 | Horizontal Bezel Offset Pixel count for horizontal offset LSByte = Byte 1 Two's complement notation is used to allow negative pixel offsets The maximum allowable offset is ± 10% of the input video horizontal resolution For example: 10 pixels right is 0x000A, 10 pixels left is 0x7FF6. Important Note: For DLP4620S-Q1 or same array size DMD, when input resolution is 1358x566 or 1220x610, the pixel offset must be in increments of 32 pixels. |
| 4:3 | 15:0 | Vertical Bezel Offset LSByte = Byte 3 Two's complement notation is used to allow negative values The maximum allowable offset is ± 50% of the input video vertical resolution For example: 10 pixels down is 0x000A, 10 pixels up is 0x7FF6. |
