Check the framebuffer resolution in:

# adb shell cat /sys/class/graphics/fb0/virtual_size

Is your LCD display able to work with this resolution, did you tried
to swap the HDMI-/DVI connector?

Here you can check if the display is set to the right resolution/timing:

# adb shell cat /sys/devices/omapdss/display0/timings
