工作学习 / 学科技术讨论 / 请教技术大牛们：笔记本电脑一般都有一个VGA输出，可以接另外一个显示器或投影仪。这个VGA输出是否和本身的LCD共享一块frame buffer？是否有办法在windows下直接写此VGA的frame buffer？
谢谢！

1) usually yes. 2) yes. but I dont' know how to write VGA frame buffer. maybe you can try to use some DDKs, or get some details from your graphical driver. some directx or opengl drivers have the APIs to fill the frame buffer.
