If it is 16:9 aspect ratio programming coming from your signal source then that is normal...A good way to check that is to minimize contrast and maximize brightness...So blacks become grey....If your black bars turn grey, but you can still see contrast/picture content and lack there of then you know it is your signal source.

If it truly is not scanning that area then try readjusting height and V linearity (preferably with a test pattern)....Some vert sections will scan more at a different frequency (which the vert may run at without sync signals) or without a blanking pulse from a broadcast
