Abstract
A television monitor display comprises a first selectable source of a first video display signal and a second selectable source of a second signal for video display. A video processor receives signals from the first and second selectable sources and controllably combines the second signal with said first video display signal. A sync separator is coupled to receive the combined signal and generate therefrom separated synchronizing signals. A controller is responsive to user selection of the first selectable source and generates a disable signal for controlling the video processor to inhibit combining of the second signal for a predetermined time.
