You'll need to post a log.  It's probably getting the mode info from
the edid your monitor supplies.  1280x768 is probably the native
resolution of your monitor.  The monitor probably scales 1920x1080
down to it's native resolution.  That said, you can add a 1920x1080
modeline to your config or use xrandr to add a 1920x1080 mode on the
fly.
