It is needed to calculate position of each last in the line pixel in memory, corresponding

the frame buffer, and clear it.

HI Yuri Muhin,

    My custom mx6dl board using ch7055a vga display color is  not bright enough.

   Ch7055a fae suggest modify to configure display related

signals data to zero during blanking period .

   Is or not can configure the blank data to zero?

Thanks,

Leo

Leo,

You may try to configure frame buffer so, that the recent pixel in each

line is zero.

Regards,

Yuri.

  The i.MX6 IPU does not provide options to configure display related

signals in predefined state during blanking period or in sleep mode.

(Previous state is kept.) 

Have a great day,
Yuri
