Horizontal Panel Size Bits [6:0]
This register determines the horizontal resolution of the panel. This register must be pro-
grammed with a value calculated as follows:
HorizontalPanelSizeRegister = _^{H-----o----r--i--z---o---n----t--a---l--P----a--n----e---l--R-8---e---s---o---l--u----t--i--o---n---(}---p---i--x----e---l--s---^{)} – 1
This register must not be set to a value less than 03h.

This 10-bit register determines the vertical resolution of the panel. This register must be
programmed with a value calculated as follows:
VerticalPanelSizeRegister = VerticalPanelResolution(lines) – 1
3FFh is the maximum value of this register for a vertical resolution of 1024 lines.
