Since this panel is dual LVDS they need to be doubled. With this change the panel reaches its nominal vrefresh rate of 60Fps, instead of the 64Fps with the current wrong blanking. Philipp Zabel added: The datasheet specifies 960 active clocks + 40/128/160 clocks blanking on each of the two LVDS channels (min/typical/max), so doubled this is now correct.
