摘要： Apparatus and methods for adjusting the video display controls in a multi-frequency video display include an EEPROM that stores multiple sets of video display parameters for the video display. A microcontroller receives input from a user, changes the stored display parameters and outputs changes in the parameters to the video display. The microcontroller also controls video display apparatus that displays on-screen menus and value indicator graphs for facilitating user input. The video display apparatus incorporates a video clock synchronized to the horizontal synchronization signal of the multi-frequency display, to keep the displayed menus synchronized regardless of the current frequency. In addition, the video display apparatus elongates displayed characters at higher frequencies to control the absolute size of displayed characters across frequencies. The present invention provides for changes to video display parameters, and for resetting the display parameters to factory standards, without manipulating electromechanical devices such as potentiometers.
摘要翻译：用于调整多频视频显示器中的视频显示控制的装置和方法包括存储用于视频显示的多组视频显示参数的EEPROM。微控制器从用户接收输入，改变存储的显示参数，并将参数的变化输出到视频显示器。微控制器还控制显示屏幕菜单和值指示器图形以便于用户输入的视频显示设备。视频显示装置包括与多频显示器的水平同步信号同步的视频时钟，以保持所显示的菜单与当前频率无关地同步。此外，视频显示装置以更高的频率延长显示的字符，以控制跨频率显示的字符的绝对尺寸。本发明提供对视频显示参数的改变，以及用于将显示参数重新设置为工厂标准，而不需要操纵诸如电位计之类的机电装置。
