Vertical Position Adjustment
Bit 7 - 0
: VPOS - These bits determine the vertical starting position for the OSD screen display. It is the vertical delay
starting from the leading edge of VFLB. The unit of this setting is 4 horizontal lines.
The equation is defined as:
Vertical delay = (Vpos x 4 +1) x Horizontal Line
The default value of it is 4 ($04) after power on. Please refer Figure 5.

Horizontal Position Adjustment
Bit 7 - 0: HPOS
- These bits determine the horizontal starting position for the OSD screen display. It is the horizontal
delay starting from the leading edge of HFLB. The unit of this setting is a 6-dot movement shift to the right on
the monitor screen. The equation is defined as:
Horizontal delay = (Hpos x 6 + 49) / P.R.
Where the P.R. (pixel rate) is defined by the HDR & Horizontal Frequency.
P.R. (Pixel Rate) = HDR * 12 * FreqHFLB
Please refer to the HDR control register at row15 / column15 for the P.R. setting.
After power-on, the default value of these bits is 15 ($ 0F). (Please refer to Figure 5.)
