Hi,

thanks,

Can u detail me, how to resize and move the overlay.

i have a ntsc_tv_var structure as following, * NTSC frame size is 720 * 480, * but due to overscan, about 640 x 430 is visible */ .xres = 640, .yres = 430, .xres_virtual = 720, .yres_virtual = 480 * 3, .xoffset = 0, .yoffset = 0, .bits_per_pixel = 16, .grayscale = 0, .red = {11, 5, 0}, .green = { 5, 6, 0}, .blue = { 0, 5, 0}, .transp = { 0, 0, 0}, .nonstd = 0, .activate = FB_ACTIVATE_NOW, .height = -1, .width = -1, .accel_flags = 0, .pixclock = 0, /* picoseconds */ .left_margin = 0, /* pixclocks */ .right_margin = 0, /* pixclocks */ .upper_margin = 0, /* line clocks */ .lower_margin = 0, /* line clocks */ .hsync_len = 0, /* pixclocks */ .vsync_len = 0, /* line clocks */ .sync = 0, .vmode = FB_VMODE_INTERLACED, .rotate = 0, .reserved[0] = 0,

Hi,

I am using beagle board connected to TV via s-video.

In the display, the top screen is slightly cut-off.

Is there any way to fit entire frame to a screen.

my framebuffer resolution size is 640x480. i am using ntsc.

S-video resolution is 720x574 (pal) or 720x482 (ntsc). The edges of that area are usually not shown by the TVs. To get a framebuffer that is fully visible, you need to resize and move the overlay.
