Hi All.


Currently we are testing different hdmi screens. Most of them has 800*480 resolution.

I know that this mode isn`t supported by hdmi driver.


So I add

static const struct fb_videomode wvga_mode = {
       /* 20 1280x1024-60 VESA */
        NULL, 60, 800, 480, 29850, 89, 164, 23, 10, 10, 10,
        0x40000000, FB_VMODE_NONINTERLACED, 0

into hdmi driver.
fb_add_videomode(&wvga_mode, &hdmi->fbi->modelist);


I was able to get this resolution support.  But the image is chopped from top and bottom a little.


Could anybody give me advice how to get correct picture? Is this Android issue or hdmi driver problem? As I understand this resolution should be supported by Android. I also know that there are successfull experiences with LCD 800*480 screens.
