My design is  UXGA@60Hz,GR, input. Use the PIN AIN0-AIN2 .

when use it  above  -20℃,it works fine.

but below -20℃,the HS  is not ok. the position of HS looks like  moved 1 pixel,which means the color is wrong when the output is YCbCr 4:2:2.According to the datasheet ,the adv7441a can work at  -40℃,but why my design can't not.

any ideas?
