Hi Brijesh,
We have started our demo, in which we are capturing 1920x1080 and rescaling it to 1600x1200 where we see flickers on the screen.
While our demo was running, in-between we set bit 15 of 0x48106000 register and we could see proper color bar pattern(without and flickers) and we also verified via monitor that the current set resolution is 1600x1200.
Thanks,
Ronak
