Screen filled display of digital video content

A dynamic region, such as subtitles, is detected in a stream of digital video, and displayed along with a static region also in the stream, such as a video region, so that nearly all of the total vertical display area of a monitor displaying the dynamic and static regions is filled. For example, when the dynamic region is detected, the vertical size of the static region is adjusted to allow the vertical display of the dynamic and static region on the monitor simultaneously, without extending beyond or reducing to less than the total vertical display size of the monitor. Also, when the dynamic region is not detected, the vertical height of the static region is adjusted to fill the total vertical display size. Moreover, iterative increase and decrease in the vertical sizes of the regions may allow for a more pleasant viewer experience.
