Dear Sir,

I recently bought my mini2440 board. I am playing with it for various qt
project for both small(3.5") and big(7") touch screen.

While switching the screen for 7 inch I recently got whitescreen. You can
see the actual screen in attached photo, however backend everything works
perfectly fine, my qt project also working, i can see it via 'ps' command,
but I am not able to get touchscreen working, it display whitescreen.

Please let me know the possible solution to overcome the problem as I am
not able to continue my project further.

I will need to work this 7 inch. screen working for my project. I have also
 changed the cable which connects board and screen, also make sure cable
connect well with socket, but no luck :(

Please let me know the possible steps to take for working screen.

Thank You for your time and consideration.

Best Regards,
Miniarm

There is no autodetection for the attached screen. You must tell your
kernel to create a different timing and resolution for different LCDs.
