20110219309 | VIDEO DISPLAY SYSTEM AND DISPLAY CONTROL METHOD - In a video display device for use in presentation, a display state on computer display screen of an application software program used in the presentation is detected. When it is detected that the application software is in a maximized display state, a video image is projected from a video display device; upon detection of any other states, a user's designated video non-display state is set up. An objective of using this arrangement is to automatically switch it to disappearance of a display image of the video display device or to displaying of an alternative image, thereby to improve the user's usability relating to non-display of a desktop image which can contain therein unexpected important information. | 09-08-2011 |
