Display resolution adjustment for OMAP4 based board

Hi, is just that i am working with a Pandaboard ES, with Android 4.0 and kernel 3.0.8, and i'm using the parallel display option with an LVDS converter and a 14'' LCD (also a 15.6'' LCD), but the resolution is not the right one, so i modified the /drivers/video/omap2/displays/panel-generic-dpi.c and the max resolution that i could get was 1330x770 but is not the right one for the LCDs, i still have a black strip because the resolution is not being adjusted to the LCD, is there a way to change it in Android, for it to be adjusted complete to the LCD??? , because when i try a bigger resolution, the system UI stops working. i really need some help on this, thanks in advanced.

    Hi Michelle.

    Assuming you are seeing no kernel errors when you set the proper resolution, you should be able to learn why Android is unhappy with the display by running "logcat" on the console.  It will be quite verbose, but looking for the word "FATAL" is quite often helpful.

    Hi Steve, i made a few tests, and this is what i got through the logcat with a resolution of 1338x778 (the 778  fits exactly to the Y resolution of the TFT LCD), i cant get to adjust the X resolution, it keeps showing 'Unfortunately, System UI has stopped', i don't know what could it be, i am using the panel generic display driver. thanks.

    Logacat output:

    Hi Michelle.

    The significant lines from logcat seem to be:

    E/AndroidRuntime( 4523): java.lang.RuntimeException: createWindowSurface failed EGL_BAD_ALLOC
    E/AndroidRuntime( 4523):     at com.android.systemui.ImageWallpaper$DrawableEngine.initGL(ImageWallpaper.java:586)

    It has the appearance of being related to a memory allocation, but that's a real guess.  Doing a quick Google on that, it appears as though a few others have run into the problem, but with no clear resolution.  An upgrade to a newer version was suggested but no indication if that helped.

    Also, in http://e2e.ti.com/support/omap/f/849/t/226489.aspx, the indication is that TI does not test beyond 1080p.

    Regards,
