I got a urgent issue that the navigation unit cannot show the expected performance. The LVDS doesn't connect to i.MX6 directly. The connection chain is i.MX6 <==>TW8838<==>DS90UB927<==>DS90UB928<==>LVDS screen. I corrected clock, bpp and checked LVDS differential voltage of i.mx. I got the display issue as the pictures i attached. Could you please tell me the other detailed possible check points? Thank you.
