Hello,

I have difficulties finding the correct timing for 320x240 display (QVGA).

For other resolutions it is very easily can be found, but not for these one.

echo 148500,1920/88/148/44,1080/4/36/5,1 > /sys/devices/platform/vpss/display0/timings

Can anyone please help ?

Regards,

Ran

    Hi Margarita,

    Thank you very much,
    But I can't see in the list the 320x240 60hz LCD resolution.
