Could you try to use these VGA timings to see if your TV can handle it?
.name = "HDMI",
.refresh = 60,
.xres = 640,
.yres = 480,
.pixclock = 39721,
.left_margin = 48,
.right_margin = 16,
.upper_margin = 33,
.lower_margin = 10,
.hsync_len = 96,
.vsync_len = 2,
.sync = 0,
.vmode = FB_VMODE_NONINTERLACED
If it works, then you could try 1280x720 manually as well. The IPU
clocks will need to be probably changed to reach this resolution.
Currently we are not flexible with the IPU DI timings in U-boot, but
we could try to improve it in the future.

Fabio Estevam
