We done with Windows CE 6.0 porting with iMX28 7" display (resolution 800x480) Now we are doing for 10" display with same resolution 800x480. The boot splash screen logo is properly displayed but after completion of device boot process (after loading all peripheral drivers), display not showing properly (Windows CE OS desktop is not displaying properly). What could be the possible cause? 10" hardware is same as 7" except size of display (even though display resolution is same i.e. 800x480). We are using display driver '43WVF1G'. First we doubt something wrong with PWM frequency but problem still observed even though backlight driver is disabled.
